What does LPF mean on a subwoofer?
low pass frequency
As we discussed earlier in this article, subwoofer amps typically use LPF (low pass frequency) filters to block high frequencies that should be playing through your speakers. A subsonic filter will attenuate frequencies so low that your subwoofer cannot reproduce them OR that humans are incapable of hearing.
What should I set my subwoofer LPF to?
As a general rule, the Low-Pass Filter should be set at a value approximately equal to (or below) 70% of your main speaker’s lowest frequency response. For example, your speaker’s frequency response goes down to 43Hz. 70% of 43Hz equals 30.1, so you should set the subwoofer’s low pass filter to 30Hz.

What kind of speaker wire does a Klipsch use?
The latest Klipschorns and La Scalas come internally wired with some Audioquest Star quad. Good enough for Roy is good enough for me. Magico uses the Canare Star Quad in their speakers. Their standmount 2 ways costs more than AK-6. So cost is not why. Benchmark sells speaker cables too.
