Edifier T5s

The budget subwoofer that's actually available in Canada. At $170 CAD it adds real bass extension to a receiver system without the outlay of an SVS. 8" long-throw woofer, 70W Class-D amp, ported design with a front-firing driver. Not reference-grade, but the community consensus is that any subwoofer beats no subwoofer, and this one ships.
