Which woofer is better?

Question

A dual chambered woofer or an ordinary woofer provide better bass?

Answer 1

Dual chamber is slightly better. Horn loaded is a lot better.

"When it comes to earth-shaking gut-wrenching low-down bass everyone knows that there's no substitute for a folded horn. Tuba Subs take advantage of proprietary folding topology to squeeze the most performance possible from small woofers, and that translates into huge bass from small cabinets, with high efficiency that keeps amp power requirements minimal. In fact, a Tuba loaded with a single ten and 100 watts input will out power an eighteen in a traditional cabinet driven by 800 watts! Yet the Tuba is no larger than the competition. Want more bass from less space? Go Tuba Sub!"

"It used to be that a folded horn sub was just too big to fit in a living room and leave space for anything else. No more. The Tuba 18 easily tucks away in a room corner. For that matter, at 18x18x19 inches it's small enough to fit in a car trunk."

"You want a horn loaded home theatre sub that can deliver over 110dB at 20 Hz. Your wife's reply is "Over my dead body do I share my living room with a big sub-woofer thing." The answer? No, not a .38 Special. It's Table Tuba, a 30x30x16 inch horn loaded sub that will do double duty as a piece of fine furniture, so you can have the sound you want and she won't complain about it."

"The most popular drivers for high end Home Theatre subs are long-throw low fs fifteens. But in a reflex or sealed cabinet you just can't get all of their potential from them. Enter the Tuba HT, a big (36x36x24 inch) folded horn specifically designed to get the most out of fifteens."

"And finally, Subwoofer Myth #4: A top of the line Pro Touring sub is going to cost you a bundle. Well, when it comes to the SB850R that's no myth, they list at better than $3,000. But you can build a T48 loaded with a 3015LF for around $300, and if you can't build your own one of our builders can, for about half what a SB850R would cost you."

"A horn loaded sub in a car? Traditional theory says horns are too big to fit in a car, but traditional theory dates from the 1940's. That was then, this is now, and now there's AutoTuba, a bass horn that can be loaded with an eight or ten inch long throw woofer."

Answer 2

For a high volume displacement subwoofer, operating below 80Hz, my first choice would be an active, self-powered, (augmented) passive radiator design [1] using a push-pull driver pair (preferably 12-inch or larger, long excursion drivers.)

For a smaller, lower volume displacement subwoofer system* an active, self-powered, 6th order or greater bandpass [2], using a push-pull driver pair, would be a viable choice for smaller rooms. (Extra care must be exercised to mitigate vent noise with BP designs.)

*(Note: the Whise­­ [3] Profunder 624 subwoofers, using Whise's patented PAM technology, are clearly the exception with respect to hybrid BP designs; 121 dB SPL @ 24 Hz at 1 m in a 2π sr space and <1% THD at 110 dB @ 31.5 Hz!)
 

Answer 3

There is no absolute answer here. All speakers are a matter of personal taste in sound. Check out subs from Infinity or Boston Acoustic. Both are excellent, and good value.

Answer 4

Dual chambered woofer will pump more punch.
