First off it was free because Parts Express sent me a couple of broken passive radiators I fixed here at the shop to save the shipping, and second, I thought it might just give me a little more low end at low volumes.
When the wife is gone, I do crank up the gains now that I have an 8 ohm load to the QSCs and I like my music DVDs to sound like I'm there at the concert, kinda sorta wide open.....as the drivers are rated at 1000 watts, and driving them at the low freqs I'm only hitting them with about 800 watts. It varies with the quality of DVDs I watch and how they are recorded. I wanted to stay out of that clipping range with the gains too. I've got the clip limiters turned on with the QSC's.
Before I built the second subwoofer, I had one QSC per driver. Bridged at 4 ohms, that's too much power for them.
That's what this DIY is.....playing with older kids toys....
