Default How to mount sub. plate amp in the box ?

Dear all,

I'm planning to build an active sub. The sub is 12" with 300watt plate amp, The box would be around 2cu/ft big sealed.

The questions are ,

Should I make a divider inside the box so that the driver and the amp. have separate air space?,

Or should I simply Cut a hole for the amp. and mount it in the box that it shares the same air space with the driver.

Are there benifits in separating the amp. and the driver in one box?

I plan to use the 300 watt plate amp from madisound, KG5230, Has anybody tried it , Does it sound good, Does it have high quality components, That justify it from being more expensive than comparable plate amp. from other sellers?

Thank you.

Just mount it, but use some kind of sealing so the mounting is airtight......

Hi Jan,

It likely comes with a gasket, no?

are you sure that u can sealed by the pressure air cannot flow out.

i had ever have the problem too much. the air can flow out at rca jack and the other on the plate amp. but when u make a divider inside the box. it's easy to sealed the inner box. therefor if that i, i choose the first question./

Won't the RCA plugs correct that when plugged in?

I am yet to see a commercial woofer that has a divider.

EDIT: Something wrong with the madisound site right now. Can't tell if this is one of the amps with a closed back on it anyway.

Hello CAl,

I have a B&W sub in my primary system, and when I checkd it out, It had a devider that is air tight.

I wonder if the rising temperature caused by the amp would affect the performance of the sub in a shared space, provided that the amp itself is air tight.
