Great Sub for the price

Like most things in life you get what you pay for. But in the $150 range this is the most potent 8" sub you can find. It has phase settings, cross over settings and standby settings.

The crossover run from 50-150 hz and so based on your front speaker's lowest freq you can pretty much set up your HT to have all Low Freq Effects (LFE) going to the sub. You do need to set all other speakers to 'small' on your A/V receiver for you to optimize LFE signals.

Also puhleeeeez invest in a good/decent dedicated sub-woofer cable if you want to really see the standby setting work. You don't need to invest in some super-duper monster sub-woofer cables, I bought $15 Philips/Magnovox cable and they work just fine.

Great LFE sub for a small/medium size room. Set the volume knob to about 2-3 'o' clock position to get a pretty decent response.
