Recently, we covered a couple of AVR discounts from Yamaha and Denon wherein the units were available at their lowest prices in a long time. Those deals are no longer live, but in case you happen to be looking for active (powered) subwoofers, there is a really good budget option on sale at the moment from Monoprice as its "Premium" Select 8-inch model is just $161 on Amazon (purchase link under the specs table down below).
Being a budget option, you cannot expect the subwoofer to go super deep, but despite that, Monoprice promises that the model can go down to 40 Hz with a 12dB boost at 45 Hz. Thus the vast majority of music in your playlist should sound great and movies too will pack a serious punch.
The plate amplifier has a high-pass filter at 28 Hz such that the 8-inch paper cone (with rubber surround) subwoofer driver does not run into over-excursion in an attempt to produce bass that is just too low for it.
There is also a fifth-order low-pass filter on the plate amplifier set at 270 Hz so that only frequencies at or below this point go through to the subwoofer"s amp. Speaking of the amplifier, it can deliver 100 watts of continuous (RMS) power at 4 ohms, which should be plenty for an 8-inch driver like this.
