DIY subwoofer power amp question

[Sawdust]

Hi,

I have a home built sub based on the Monolith drive unit and was wondering about using one of these: http://www.bkelec.com/Modules/mf300.htm from BK to drive it.

Does anyone have any experience of these amps or know any reason why it would not be suitable.

Many thanks
Mike

BK have an excellent reputation.
They are also experts at subwoofer design.
I'd email them asking for advice regarding which module they recommend for your application.

I used to use one, functions fine as long as you do all the processing of the signal via the amp.
You'll need to do a bit of soldering and house it somewhere safe from prying fingers. I built mine in to the (diy) sub.

Currently, I'm using 2 Monolith drivers in separate ~40 litre sealed boxes, powered by BK's 500w sub plate amp. Pretty tasty IMO!

I was planning on letting the AV amp do all the processing so I don't think I need any extra features so I think I will go for it and see how it goes.

Good point Nimby - they do seem to be a company that know what they are talking about and are keen to help.

Hi Sawdust

I've been using a 200 watt amp module from BK for about 10 years now, it is currently running 2 monolith drive units with no problems, its plenty loud enough for me so 300watts should be ample, I think they are conservatively rated! If you run it from an AV amp then you can set levels crossover from the amp no problem, you can also add a behringer feedback suppressor with room eq if you think you need it.
I've just got an Onkyo TX805 and the Auddessy XT worked well at integrating the sub with my room and main speakers, it has separate filter bands for the subwoofer going down to 25Hz.
So I would say go for it

BK modules are bomb proof

I enquired of BK by email about their bass module to see if it matched my special needs.

They immediately made some special tests on their sophisticated equipment and provided me with further specs and graphs.

If that's what you call "semi-professional" I'll take BK over the Chinese import box shifters in the high street any time.
