B-Large Posted December 15, 2013 Report Share Posted December 15, 2013 I have a plate amplifier from a polk audio dsw micro pro 4000 home sub. I once owned one and had some problems with it so the sub went back but i got to keep the working plate amp. Since the amp is proprietary to polk there are not many specs available. according to polk it's 1200 rms. Not that I need another project or another home sub but would like to make use of this amp. http://www.polkaudio.com/products/dswmicropro4000 Still reading on transmission lines but i know that i want to build one. Either way the problems i have are, what impedance to choose and how much power do i really have here? The only thing i know is what polk says and that the sub was around 6.5 ohms measured by me.
