So definitive technology wouldn't replace the amp that blow,,,soooo I removed amp and noticed the mids and highs have a crossover but the subwoofer amp that blow was also the crossover for the sub, took out amp wired in crossover for subwoofer and tower sounds amazing. Lol minus Definitive technology amp!!!!hahahah

Installed it to a subwoofer and it wasn't as expected. It did increase the bass but no where near what I thought it would do.

Measured coil inductance with capacitor in series gives resonance at 146 Hz. If you like to shift the cross-over frequency higher you may remove the screws and the ferromagnetic core blades to boost it to 240 Hz. Or, remove only some of the core blades to tune it as you like. The capacitor is 188 uF and the inductor with core should be about 6.25 mH with self-resonance above 200 KHz. Since this is a resonating circuit the impedance of the driver in parallel to the capacitor (and in series to the coil) only has impact on the slope, 8 Ohms driver will cause stepper pass-thru slope of the signal.

Just quit for no apparent reason after about 2 minutes. I only had it hooked up to an 6.75" 8ohm woofer, supplying it with 20w (max) from 1 channel of a mini-amp. It's too bad because it sounded like the frequency cut-off was right on, so I wish it would have lasted.UPDATE.... I tried replacing the capacitor on this crossover and it still doesn't work. I'm not sure what else could go wrong with a crossover, except maybe the winding shorted or something, but that still makes no sense because it never got hot and I didn't over-amp it.

I bought this to fix a powered Polk Audio sub woofer. The original power amp fried beyond repair. So I acquired an NHT SA-1 mono amp to power it. I got this crossover along with banana plug terminals to turn this once powered sub into a passive sub. It works beautifully. This crossover is fully compatible with pre-amp adjustments of frequency response. The top end of this crossover is 120hz. It produces loud, thunderous bass; even more than this sub ever did when it was new!If you are making your own sub, or repairing an old one, I HIGHLY recommend this crossover.

Works well for tight low end response for fine tuning my Home Theater passive sub. I have only one concern. The electrolytic capacitor has a working voltage rating of 50 volts. This is fine up to 100 watts RMS. If you want to run it with higher wattage for extended periods such as a car environment I would suggest replacing it with a 100v or higher WVDC rated capacitor. I paralleled a 3.3uf 250v poly cap rated at 250v as a bypass cap for safety since my HT sub amp is running 150 watts RMS. So far working well.
