Dual Electronics L12SW Subwoofer Speaker

Pros: Cheap, relatively powerful and not too large.
Cons: Doesn't rattle the dishes in the kitchen:)

I bought this one to replace a passive JBL sub that used 4 small drivers in a push pull, in phase out of phase, arrangement. The Dual made quite a difference and it was surprisingly cheap off of an online auction site.

I located the sub behind my sectional where I sit and with a good DTS soundtrack or a good concert DVD, it feels like I am sitting with the drummer or varioius rumbling and exploding sensations when the hero blows up half the town getting the bad guy. This is a very good and inexpensive sub for the money.

Boomy? Perhaps, but on a budget, not bad. There are plenty of controls to tailor the response of the woofer from in your face boominess to subtle vibrations.

There is a frequency cutoff potentiometer, a volume control, a phase switch, and a manual on/off switch for those like me who have a low hum on the cable coming in that I am too lazy to troubleshoot.

Bottom line, good enough for the job. Need more bass? Buy a couple of them and daisy chain them. I am going to!!

Pros: Price, Frequency response
Cons: No LFE

I've had this sub for a couple of weeks now, and I really like it. It adds a lot to movies and music. For the price I don't think you can do much better. A little boomy like all subs at this price, but a good sub nonetheless.

Pros: Price, clean lows when properly adjusted
Cons: none at this time

I replaced an old Bose passive sub with the Dual L12SW powered three months ago and am extremely pleased. This is a new version with the port in the back and improved frequency response and sleep mode. It has both low and high level inputs and low level outputs in case you want to add another sub. Although just one gives all the low end I need.
