I would like to announce the availability of yet another product

The Quattro MFW-15 Driver 1000Watt amp.  $495.00 available now

This is designed and tested to work with the MFW-15 drivers in a SEALED 2.5ft^3 cabinet per driver, utilizing 1,2 or 4 drivers.   Mark has a dual woofer cabinet design and I will be adding pictures and pricing as soon as that is available.

This was designed with the DIYer in mind that wanted to build their own box, but might not want to spend all the time learning and money on trying to get good response and this also gives you limiting, something that is VERY well needed when using these drivers

Tested to both Mark Seatons and my own standards, the amp has been modified to yield a response curve that will benefit from room gain and give very good response.  The Near Field Measurements are ~+/-3db 20hz-160hz   Couple that with room gain and you could be seeing very impressive levels down to the low low teens.

While this amp starts out life as the Dayton SA1000 amp, I heavily modify it to get both the limiting and EQ required for a seamless playback that will not having you running to turn it down due to ugly noises or having to cycle the power button due to shutting the amp down.

I know many of you were unable to purchase these drivers, Mark and I have been looking into a similar driver(upgraded) that will be in the same price range.  This amp will then also be modified and available for that driver.

Kevin,  how/where do I order this amp?  Also, what is the smallest enclosure size recommended.  Is it 2.5 cubic feet per driver?  Could I go any smaller without giving up too much performance?

For ordering just email me orders@motorcitycustomaudio.com

This amp was developed for a 2.5Ft^3 box and is the sweet spot on the size, going to a 3.0Ft^3 box is fine also, I will look into a smaller box size and see what it does. 

How small are you thinking?

Kevin,

Any idea of what would happen if I put 4 drivers, (2 per side) in a 8 cubic foot box.  Would I be sacrificing a lot of low end extension?

from what we see in the model you will get about .5db gain above 60hz, from 50-55hz it will be the same and then below 30hz it will be about 1.5db less efficient.  I do not see any problem with the limiting in the smaller cabinet.
