I'd like to augment my current stereo speakers, which go down to about 40 Hz, with a subwoofer. In the future, I'd like to add center & rear channel speakers for a full "home theater" rig. To the best of my knowledge, the subwoofer will need to meet the following requirements:
1. Flat, smooth, frequency response to well below 20 Hz. (I listen to both classical organ & D.J. Magic Mike)
2. Flat, smooth frequency response up to 150 Hz (I plan to add those meager rear surrounds)
3. Fast, accurate response for music - I don't want "one note boom boxes" that thud only for movie effects. The subwoofer must transition seamlessly with my fast main speakers and be unobtrusive in its crossover (which will be done by an AVR, hopefully with individual turnover points for the main, center, and surround speakers)
4. I would prefer to buy an undervalued, lesser-known, used subwoofer at a ferocious discount, but I'm willing to buy new if I must.
I've previously owned two subwoofers. One was the shining example of what I want, the other the stinking example of what I don't. The sub that impressed me was a M&K MX350THX. Its two 12" drivers were low-distortion, high output-capacity, and played down into the true subsonic range. I successfully mated it with a variety of speakers (for music & movies) and never noticed the sub as being distinct from the main speakers. Unfortunately, they aren't made anymore & are exceedingly rare on the used market.
The sub that stunk to high heaven was a JBL 12" that never mated successfully with any speaker that I tried it with, announced its presence at its preferred note (and only at that note), and wouldn't smooth out even with massaging by the receiver's room correction.
The majority of subs that I've researched online don't go very low into the bass frequencies. They're basically self-powered woofers - NOT true subwoofers. Some that DO seem to go low, I've read bad things about if you try to run them up above 40 Hz (the Carver & Sunfire models come to mind).
Subs that look good on paper, but that I haven't auditioned include the Definitive Tech models. How are they with music? As the title of this post says, I'm looking for advice. My priority is music, with the home theater stuff a distant second. What subs do you recommend? Thanks! Boomzilla
