JBL 2205, 2225 and 2226 woofers aren't subs, but they are some of the best sounding midwoofers I've ever used. They have well damped cones that provide smooth midrange and flux stabilization that reduces distortion.You can always add subs, which smoothes room modes in addition to increasing bass extension. I use four π speakers and three π subwoofers, and the sound is beautiful. It is delicate and powerful at the same time.
