Topic: How to build: Battery box w/ adjustable bass roll-off?

[TheMetalist]

I need a battery box with an adjustable bass roll-off filter (no level control needed).

As they are pretty expensive to buy a friend of mine will help me to build one. Unfortunately he doesn't really know how to do it (he is an electrician but doesn't know a thing about taping). I need a schedule and what components he has to use.

It will be used together with my SHARP Minidisc recorder MD-MT770W and Sound Professionals Mini Binaural Microphones SP-BMC-2.

Any help is appreciated. Thanks.

Use polypropylene capacitors, and 10kOhm resistors.

Wheee! Thanks.

That's a lot of english for two dumbass Swedes like us. I hope my friend will understand this. I don't. 

I'm just interested in the battery box and bass roll-off. The mic part mixed together with the battery box makes everything a bit confusing for me.

Any description which is easier to understand available? Eh...
