Volume - While the volume control on your Kenwood will control the sub and the Polks simultaneously, the volume control on the sub is used to set its volume relative to the Polks. The sub will have two adjustments (maybe 3):ġ. Select A+B speakers on your Kenwood, turn on the subwoofer (it will have it's own amplifier, unless you buy a passive sub.which I don't recommend for your situation), and voila! You would just run two pairs of speaker wires (one pair for right, one for left) between:Ī) the B speaker terminals on your Kenwood, andī) the subwoofer speaker input terminals. Most mid-grade subs allow for speaker-level interconnection (one for left channel and one for the right).
You don't necessarily need a sub that goes all the way down into the low 20Hz region.most of the action and the punch of the electric bass, low notes on the piano, etc is in the range of 35-100Hz. Keep in mind, though, that you may need a larger sub (bigger cone size and more powerful amp) for larger rooms. I use a Pioneer SW8MKII in my workshop system to complement a set of Snell JIIs, and have been very impressed with it. Your little Polks cannot be expected to do much meaningful bass below 50-60Hz or so, and not do it very well below 100Hz.Ī decent subwoofer can be had for little $ used, and the small 8-10" offerings from Pioneer, Polk, Yamaha etc can be had for less than $150 new. You are a perfect candidate for a subwoofer.
