The MiniDSP would be perfect if they would make a limiter and/or compressor software module available. I've seen talk of this on their forum, but nothing has emerged so far.

Thanks for the heads up on the maximizer. Maybe I'll go for a MiniDSP, they're cheaper anyways and my roommate is majoring in programming things like those.

Subharmonic, for voltage swing do you mean on my current plate amp or on the Crown I'm powering my mains with? I'll have to look up how to check that.

Radian, thanks for the recommendation, I'll lower the crossover right now. I was wondering if that would be a factor. As for what I said about the HP, I was saying that with the thinking that my mains might be playing too much of the same bass notes and canceling out some of the sound as the CV's will play down into the upper 30's with some authority on their own.

They certainly will, a 6dB high pass is virtually useless.

Unhook the plate amp from the sub.....put a voltmeter center on it set to VAC. Play a 60hz test tone through it....see if you getting volts in the high teens low twenties. Ifso your amp should be easily powerful enough for the sub.

Were the drivers broken in before mounting? Not sure if it is in the home audio plans but is in the PA sub plans. They will sound better when the spiders and surrounds have some hours on them

Mini dsp sounds cool!

Put the money into a good EQ.

Inquiring minds want to know. What do you consider good EQs for home?

IMO, get a decent sound card with more than 2 output channels, or a pair of them with only 2 channels. Install it along with a quiet power supply into an old PC, then use this software.
Edit:I apologize for being overly terse.

Basically, for home systems you don't need the precaution of putting hardware limiters in ahead of the amplifiers. So if you are like me and use your computer for all your audio, you can do all the processing in your computer.

The best understood way to do this processing is using Impulse Response Filters. For this you need 2 tools: a filter generator, and a processor to apply the filter to the audio. The above link only has a filter generator. The filter processor in Windows is going to be a Foobar 2000 plugin. In Linux, brutefir. I dunno what you'd use on a Mac.

The hard part of this is setting up the filter processor. There's a PDF detailing how to use the one I noted above, and it appears someone created a graphical interface for it, but it appears long gone from the net. There's another filter generator called PORC that seems easier to use, but uses different math to generate the filter.
