The bass clarinet is a popular member of the clarinet family due to its plethora of tones and practicality in orchestral pieces.
When it comes to recording or spot-miking a bass clarinet, a microphone is surely needed. So what microphones lend themselves best to the bass clarinet? Here are my top 3 recommendations:
Top 3 Bass Clarinet Microphone Recommendations:
- Schoeps MK4/CMC 6: The Schoeps MK4/CMC 6 (link to check the price on Amazon) is a cardioid condenser capsule (MK4) and mic amplifier (CMC 6) combo. This microphone is incredibly accurate and works wonders as a spot mic in orchestral settings as well as in studio environments when reinforcing or recording the bass clarinet.
- AKG C 414 XLII: The AKG C 414 XLII (link to check the price on Amazon) is a multi-pattern large-diaphragm condenser microphone. The immense versatility of the C414 makes it a top recommendation for many instruments. It can be used in nearly any miking technique in order to best reproduce an accurate capture of the bass clarinet's sound. The AKG C 414 XLII is my recommended large-diaphragm condenser microphone for the bass clarinet and the rest of the clarinet family.
- DPA d:
dicate4011: The DPA d: dicate4011 (link to check the price on Amazon) is a remarkably precise small-diaphragm condenser microphone. The 4011A high-quality preamp model is an industry-leading spot-miking microphone while the 4011C compact preamp model is perhaps the best instrument clip-on mic in the world.
Let's discuss these microphones further in this article and talk about why they make for excellent bass clarinet mics.
“Best” is a dangerous word. There is really no such thing as a “best microphone” for any situation. The microphone(s) listed in my Recommended Microphones And Accessories” page are simply my recommendations. These recommendations are based on my own experience and are mindful of budget. It would be easy to suggest an ELA M 251 or U47 for most scenarios. However, these tube mics are very expensive, putting them out of a hobbyist's price range and making it difficult for professionals to make their money back on the gear.
Another important note is that the microphone or equipment you choose is not the most important part of recording audio. In fact, there are many factors that are arguably more important than the choice of microphone. These include:
- Performer (whether a musician, speaker, or otherwise)
- Microphone technique/placement
- Number of microphones used
- Natural sound of the room
- Content (whether that's the song, discussion, or otherwise)
- Signal chain (including mic cable, preamplifier, console, and/or interface/computer)
With that being said, some microphones and gear suit some instruments better than others, prompting this series of articles under “Recommended Microphones And Accessories.”
What Does A Bass Clarinet Sound Like?
When choosing a microphone for any application, it's to our great advantage to know the characteristics of the sound source. So what does a bass clarinet sound like?
An interesting note on bass clarinet is that most of its body is a cylindrical tube, whereas the oboe, bassoon and saxophone are conical tubes. Because the bass clarinet is cylindrical and is played by closing one end of the tube (where the mouthpiece is), the bass clarinet only produces odd harmonics.
The bass clarinet has a range from B♭1-B5, though this instrument is typically played in its upper register (A3-F5), which is suitably named the “clarinet register.” The notes in the clarinet register sound full and brilliant. The timbre of the notes below this register is dull, but warm, while the timbre of notes above this register sound sharp and piercing.
Sound emanates from the bass clarinet's bell (where the clarinet “points”) and from the top of the instrument. In general, the higher frequencies are more directional than the lower frequencies, which leave the instrument in an omnidirectional sense.
A Note On Miking Bass Clarinets
Bass clarinets typically find themselves in orchestral ensembles, so we'll discuss
One technique is spot-miking. To spot-mic a bass clarinet is to focus in and isolate its sound as much as possible.
Position a directional microphone between half a foot to three feet away from the bass clarinet and point the mic at the keys in the centre of the instrument (not at the bell). Experiment with the distance and positioning to get the best sound.
Clip-on mics are another common strategy for close-miking bass clarinet. Simply clip a small directional microphone (like the DPA 4011C) to the bell of the bass clarinet and point at along the tube at the keys. Again, experiment with mic position to find the “sweet spot.”
When miking a solo bass clarinet in studio environments, experiment with greater distance from the instrument. Distant-miking allows the fullest sound of the bass clarinet to unfold before hitting the microphone. This technique works best when the room also sounds nice.
For more information on microphone placement, check out my article Top 23 Tips For Better Microphone Placement.
Frequency Range Of Bass Clarinet (B♭)
- Overall Range: 58 Hz ~ 12,000 Hz
- Fundamentals range: 58 Hz – 998 Hz (B♭1-B5)
- Harmonics range: 116 Hz ~ 12,000 Hz
- Formant range 1: 1,500 Hz – 1,700 Hz
- Formant range 2: 3,700 Hz – 4,300 Hz
So we want a microphone that will accurately capture the true sound of the bass clarinet. Knowing the fundamental frequencies and the harmonics of the bass clarinet is a great place to start. On top of this, there are a few more criteria to keep in mind when choosing the best bass clarinet microphone.
What Factors Make A Bass Clarinet Microphone?
Let’s discuss a short list of the critical specifications that make up excellent bass clarinet microphones:
- Flat/Extended Frequency Response: The bass clarinet has a wide variability of tone and most often finds itself in orchestral music. Therefore, it is best to capture the sound of this instrument as cleanly and accurately as possible. Choose a neutral microphone with a flat frequency response to reproduce the sound of the clarinet without any colouration.
- Directionality: Choose a microphone to best suit your miking techniques and performance situations.
- Sensitivity: The bass clarinet can be quite expressive. Choose a microphone capable of accurately reproducing the nuances in tone and the dynamic range of a bass clarinet.
And For Live Applications, A Few More Considerations:
- Price: Pick a microphone you can afford. This is important for performers and crucial for venue owners and audio technicians who plan to make money from their microphone investments.
- Cardioid Directional Polar Pattern: Select a cardioid directional microphone to work well with fold-back monitors and on noisy stages.
- Size: Though not a major factor, size does play a role in microphone placement live.
So we have a general idea of what we’re looking for. Let’s discuss the recommended bass clarinet microphones through this lens.
The Schoeps MK4/CMC 6
The MK4/CMC 6 is a capsule/microphone amplifier combination with the MK4 being the cardioid small diaphragm condenser capsule and the CMC 6 being the mic signal amplifier. This microphone is an excellent choice for spot miking bass clarinet live or recording the instrument in a studio setting. The Schoeps MK4/CMC 6 get the top recommendation on many woodwind instruments, including all the clarinets.
Schoeps Mikrofone is featured in My New Microphone's Top Best Microphone Brands You Should Know And Use.
Frequency Response Of The Schoeps MK4/CMC 6
The frequency response of the Schoeps MK4/CMC 6 is rated from 40 Hz – 26,000 Hz. This range goes above the range of human hearing (20 Hz – 20,000 Hz). The frequency response graph is as follows:
This beautifully flat response picks up the full range of the bass clarinet with pristine accuracy. An accurate capture with no added “colour” from a microphone is ideal when recording orchestral instruments like the bass clarinet.
For more information on microphone frequency response, check out my article Complete Guide To Microphone Frequency Response (With Mic Examples).
Polar Response Of The Schoeps MK4/CMC 6
As mentioned, the MK4 is a cardioid microphone capsule. Here is its polar response graph:
This microphone has a very consistent cardioid polar pattern and excellent rear rejection. Contrary to many cardioid mics, the MK4 does not “colour” sound coming in from its sides. This yield a much more natural sound than many cardioid microphones on the market.
The MK4 provides superb rejection and, therefore, is a fantastic choice when spot miking the bass clarinet in an orchestra. It's also great when recording the clarinet in an environment where other instruments are also being played.
For more information on the cardioid microphone polar pattern, check out my article What Is A Cardioid Microphone? (Polar Pattern + Mic Examples).
Sensitivity Of The Schoeps MK4/CMC 6
The sensitivity rating of the Schoeps MK4/CMC 6 is given as -36.5 dB (V/Pa), 15 mV/Pa. This value is within the typical range for condenser microphones and the microphone will output a strong mic signal.
For more information on microphone sensitivity, check out my article What Is Microphone Sensitivity? An In-Depth Description.
The small diaphragm of the MK4 reacts with pristine accuracy to the variations in sound pressure around it. The sensitivity of the MK4 diaphragm gives the microphone a spot-on transient response and picks up on the subtle nuances of the bass clarinet performance.
Price Of The Schoeps MK4/CMC 6
As of the writing of this article, the MK4 with CMC 6 amplifier goes for about $1,500 USD. That's quite expensive for a bass clarinet microphone. However, the value and versatility of this microphone is worth every penny.
The MK4/CMC 6 is nearly ideal for spot miking any instrument in an orchestra.
In the studio, the microphone will surely be a go-to for capturing sound sources as accurately as possible.
For even more versatility, consider checking out the Schoeps MK5, which has a switchable option between cardioid and omnidirectional mode.
For more information on the price of microphones, check out my articles How Much Do Microphones Cost? (With Pricing Examples) and Top 20 Most Expensive Microphones On The Market Today.
Size/Mounting Of The Schoeps MK4/CMC 6
The MK4/CMC 6 is a small pencil microphone measuring 138 mm (~5½”) long by 20 mm (~¾”) in diameter. The microphone is easy to mount to a stand and fit in with an orchestra or band as a spot mic. In the studio, the mounting is even easier due to increased flexibility with the potential microphone positions.

The AKG C 414 XLII
The AKG C 414 XLII is a multi-pattern large-diaphragm condenser microphone modelled after the legendary C414 microphone. With 9 selectable polar patterns, 3 high-pass filters, and 4 pads, the C414 is king when it comes to versatility. Nearly any bass clarinet miking technique will benefit from the C414 XLII.
AKG is featured in the following My New Microphone articles:
• Top Best Microphone Brands You Should Know And Use
• Top Best Headphone Brands In The World
The XLII is the model specialized for vocals, whereas the XLS is specified to instruments. Though the differences are slight, I recommend the XLII over the XLS since the bass clarinet shares similarities to the human voice. Both microphone models deserve a recommendation but I'll be talking about the XLII here.
Frequency Response Of The AKG C 414 XLII
The frequency response of the AKG C 414 XLII is given as 20 Hz – 20,000 Hz. The C414 XLII (omnidirectional position) frequency response graph is as follows:
I chose to show the frequency response of the C414’s omnidirectional polar pattern (of the 9 polar pattern options). This is because
The C414 has a very flat frequency response. This means the microphone will reproduce sound (in the form of a mic signal) with pristine accuracy.
The slight boost in the upper presence range will help to accentuate the bass clarinet in a studio mix. The boost of the upper-frequency range helps enhance the “brilliance” or “air” of the bass clarinet and the space in which it is being played.
The high-end boost and the brightness that comes with it could be subjectively good or bad. It all depends on the role of the bass clarinet, the room, and how we want the clarinet to sound. The roll-off at the very top of the frequency response range help to
As for the high-pass filters (HPFs), the C414 will capture the entire bass clarinet's range with the 80 Hz HPF engaged. I'd recommend experimenting with the filters, listening to which sounds the best to you. I typically end up with either the 80 Hz or 160 Hz HPF on clarinet.
If we were tasked with miking the other members of the clarinet family, another HPF would likely work better. For example, the lowest octo-contrabass clarinet would likely benefit from no HPF at all.
For more info on high-pass filters, check out the following My New Microphone articles:
• What Is A Microphone High-Pass Filter And Why Use One?
• Audio EQ: What Is A High-Pass Filter & How Do HPFs Work?
Polar Response Of The AKG C 414 XLII
As mentioned, the AKG C 414 XLII has a whopping 9 selectable polar patterns. A common choice for recording the natural sound of a solo clarinet is the omnidirectional mode. The C414 omnidirectional pattern graph is shown below:
I chose to show you the graph the coincides with the omnidirectional mode polar pattern since it’s a common pattern for solo bass clarinet studio recordings. In orchestra spot-miking settings, a cardioid-type pattern will work better. You can check out the other graphs in the manual here.
For more information on the omnidirectional microphone polar pattern, check out my article What Is An Omnidirectional Microphone? (Polar Pattern + Mic Examples).
Sensitivity Of The AKG C 414 XLII
The sensitivity rating of the AKG C 414 XLII is given as 23 mV/Pa (-33 dBV ± 0.5 dB). This means the microphone will output a strong signal when miking the bass clarinet.
The large condenser diaphragms of the C414 are also very sensitive to changing sound pressure levels. Therefore, the mic's accuracy is spot on when capturing transients and nuances in the bass clarinet sound.
The DPA d:dicate 4011
The DPA 4011 is a top-of-the-line instrument microphone in spot-miking and clip-on miking situations. The 4011 is a cardioid condenser microphone capsule that comes with the choice of two attachable preamps: the High-End Preamp (making it a 4011A) or the Compact Preamp (making it a 4011C).
The DPA 4011 is featured in My New Microphone's 50 Best Microphones Of All Time (With Alternate Versions & Clones).
DPA is featured in My New Microphone's Top Best Microphone Brands You Should Know And Use.
The 4011A works amazing well as a spot-mic in loud environments and as a deadly accurate transducer in the studio. The 4011C has much of the same specs but is better suited to clip directly onto instruments, making it one of the best, most versatile clip-on microphones on the market today.
Frequency Response Of The DPA d:dicate 4011
The frequency response range of the DPA 4011C is given as 20 Hz – 20,000 Hz, which coincides with the entire range of human hearing. Here is the frequency response graph of the DPA 4011A:
The graph shows us the response of sound coming in at various angles. Because the 4011 is a cardioid capsule, there is maximal rejection at 180-degrees. We notice here the lines of 0, 30, 60, and 90 degrees are all very much similar to one another, albeit at lower sensitivity. This tells us that the 4011's polar response is consistent.
The flatness of this response graph tells us the DPA 4011A will capture an incredibly accurate sonic picture of a sound source. The 4011C's frequency response is nearly identical.
Polar Response Of The DPA d:dicate 4011
As we've discussed, the 4011 capsule has a cardioid polar pattern. Here is the polar pattern graph of the 4011A:
The consistency of the 4011's polar pattern makes it sound beautifully natural when spot miking instruments. There is a negligible amount of off-axis colouration, which is often the main con of cardioid patterns.
Pointing this microphone properly at a bass clarinet will yield great results. The amount of isolation attainable is fantastic with spot-miking techniques and more isolation is possible with the 4011C compact preamp clip-on version.
Note that the polar response of the 4011C is nearly identical to that of the 4011A pictured above.
Sensitivity Of The DPA d:dicate 4011
The sensitivity rating of the d:dicate 4011 is given as 10 mV/Pa; -40 dB re. 1 V/Pa (nominal, ±2 dB at 1 kHz). This rating is true of both the 4011A and 4011C preamps.
Though this may be considered on the low end of the condenser microphone sensitivity spectrum, the 10mV/Pa sensitivity works quite well in loud orchestral or band situations. The microphone will output a strong signal, but won't be overly influenced by all the sound around it. Rather, its pickup will be focused on the instrument it points at.
The reactivity of the 4011 capsule's small condenser diaphragm is top-notch. Transients and nuances in the bass clarinet's sound will be picked up effectively and accurately by the amazing DPA 4011.
Price Of The DPA d:dicate 4011
With price points of roughly $1,900 USD for the 4011A and $1,800 USD for the 4011C, these DPA microphones are likely out of many clarinetists' budgets. However, if you're looking for the best option for spot-miking or clip-on-miking, these are honestly your best bet.
The versatility and pristine sound quality of these high-end small diaphragm condenser microphones make the investment well worth it, in my opinion. That being said, I'll be holding off on buying one of these for a good while!
Size/Mounting Of The DPA d:dicate 4011
The 4011A high-quality preamp model measures 170 mm (6.7 in) long, 19 mm (0.75 in) in diameter and weighs 158 g (5.6 oz).
4011A's are excellent spot-microphones and are able to fit in many of the practical positions in orchestral or band settings in order to capture the best sound of the bass clarinet.
The 4011C compact preamp model measures 64 mm (2.5 in) long, 19 mm (0.75 in) in diameter and weighs 58 g (2 oz).
4011C's make for excellent clip-on microphones when used in conjunction with the GSM4000 gooseneck shock mount. Though not all that common on bass clarinets, clip-on mics may wind up being the best choice for a consistent pickup of woodwinds.
So these are three of the best microphones for capturing the sound of a bass clarinet. Of course, there are many microphones that sound amazing on the clarinet, but in considering price and setting, these are my top 3 recommended bass clarinet mics. Let’s recap:
- Schoeps MK4/CMC 6: Top recommended mic for bass clarinet.
- AKG C 414: The recommended large-diaphragm condenser on bass clarinet.
- DPA d:
dicate4011: Recommended for spot-miking or as a clip-on bass clarinet microphone.
- Royer R121: (recommended ribbon mic on bass clarinet)
- Sennheiser MD441 (best moving-coil dynamic mic on bass clarinet)
