___________________________________________ Thanks for the reply, Scott. I figured as much. Unfortunately most folks cannot afford a proper test facility, so one does what what one can with what

You should assume that loudspeakers will have frequency response variations, just as microphones do. Also just like microphones, the enclosure will have a significant effect on the

easy to measure the low frequency response of omni microphone capsules. You only need a small woofer mounted in a small enclosure. _______________________________________ Sidebar Question ---> How

So - I just had a good look at one of my unused 5024 capsules.... I'm not seeing a small vent hole. Can anyone confirm this? Do they maybe vent through the front spacers? I did see some open

Heaps of thanks Ken. I’ll make those changes and yeah, verify with my younger son’s gf who is a double major: computer engineering/physics. She has lots of electronics experience. But having all

A bit off-topic, perhaps, but since the subject is being

It would have been a list or two ago, and long gone from my archives.? But at one point somebody (I think Mark Strong from JLI) suggested putting a long piece of tubing behind an omni capsule instead

It's pretty easy to measure the low frequency response of omni microphone capsules. You only need a small woofer mounted in a small enclosure. There needs to be a sealed hole to connect to the

Hello everyone, small insert here - I like using low frequency tactile transducers, also known as bass shakers for the reproduction of infrasonics. Attached to a structure you sit or lay on, you

An omni electret's LF response is usually limited by * the small hole which prevents it acting as a barometer * the electronics. The hole is easily seen on the side of a B&K capsule but should be

Do you really still believe the manufacturer's specs?

At this point in time, I doubt I have anything that will reproduce 15HZ or anything below 20 for that matter, but the wish to capture these frequencies is really for some future when I may have a

I'm just a punter, but I am amazed by the amount of low bass that even a 10mm omni electret will capture. It's usually too much. To explore this, i would look into the following: * using an

Question on this one: What will you use to reproduce the infrasonic stuff you capture? ;-) Jules -- Best Regards, Jules Ryckebusch 214 399 0931 Linkedin

Interesting article. An MKH-20 would be a good choice, but alas out of production and no more affordable than an Earthworks. I did find the Behringer ECM8000. Very affordable an rated FR goes down to

Infrasonics!? That was a rat-hole I arm-chaired down into a decade or so ago.? Record meteors, landslides, volcanoes, etc.I did hang out with the local student section of the AES who had a project

Hello everyone, I was thinking how cool it would be to record a thunderstorm with a pair of earthworks M50 measurement mics seeing as their frequency response goes way down into subsonic territory.

Hi David, You're pretty close with your circuit redraw. Notes: * USB sockets supply 5v DC * your output connections are unclear, and possibly incorrect. The output is after C1 * as Jerry mentions, R1

I have serious doubts about the use of a 5.6 ohms resistor rated at 10W. Also C1 at 0.2uF will kill most of treble.
