JBL 2241H 18" High-Power LF Driver

The 2241H 18" low frequency transducer represents the results of JBL's latest engineering research in high power transducer design. For increased power handling while reducing power compression, a unique direct voice coil-to-air heat dissipation method called Vented Gap Cooling has been used. This process pumps air through the magnetic gap and directly over and around the voice coil to provide immediate heat transfer and reduction in operating temperature. Through the use of new computer-aided magnet optimization and analysis techniques comes a new weight-optimized Symmetrical Field Geometry (SFG) magnet structure, resulting in a reduction of overall driver weight and a significant reduction in harmonic distortion. This new magnet structure offers much of the weight advantage of rare earth magnet structures without their prohibitive cost.

JBL 2241H 18" High-Power LF Driver
JBL 2241H 18" High-Power LF Driver is rated 4.75 out of 5 by 4.
Rated 5 out of 5 by from AMAZING SUBS! WILLL BLOW DOWN SHEET ROCK!I have been searching for a sub that can keep up with my high bass demands for atleast a decade. I have owned cheap 18" P.A. subs, a velodyne DD-18, sonance THE SUB, and the titanic 15" kit. all of them fell short of my needs for home theater. The JBL pro is amazing with HUGE limitless output. I baught the jbl 4642a with 2 of these drivers and it punishes through movies at 120db's powered by a crown DSi 4000. Don't mess around with lesser subs if you are serious about home theater... use the real thing they use in theaters.... this sub blew my mind.

Rated 5 out of 5 by from The Best!Simply the best 18' driver made period. The presence and sound stage are excellent! The price might seem high but you get what you pay for and it's well worth it. You will enjoy this product for many years to come!

Rated 4 out of 5 by from Hummm...I didn't buy this driver from PE but I've used (by request) and bought it (with someone else s credit card)! I find JBL raw drivers are over priced. They are only a speaker and anything over $300 for some metal, paper, and a bit of wire is ridiculous!!!I would take a Selenium driver of JBL any day the performance is about the same but minus the dumb price. (And Selenium, just because I pat you on the back does not mean increase your price. If you do you'll be the same as JBL and I won't use your stuff). That is what I have to say about this driver.

Rated 5 out of 5 by from The only 18 inchJBL pro produces the only drivers that combine fantastic tonal quality, dynamic and reliability. their know how is legendary. At this price this is a steal to own professional quality large studio monitor components. Bass becomes physical and its restrained power makes it classy. I use them with JBL 2226, 2446 and 2382 and JBL tweeters in a 4 ways system. Electronic cross overs Rane AC23B, power Bryston, sources CD and LP Linn.
