Product Details

JBL 2242H 18" Maximum Output LF Driver 8 Ohm

The 2242H is ideal for use in high output subwoofer systems with bass extension to 25 Hz. The total peak-to-peak excursion of the 2242H is 18 mm, within 10% linearity. The Super Vented Gap™ (SVG) series of low frequency transducers takes the patented Vented Gap Cooling™ (VGC) heat dissipation process one step further. A completely new motor structure design extends the pole piece above and below the top plate to improve gap flux symmetry and increase thermal conductivity from the voice coil to the pole piece. In addition to the benefits of Symmetrical Field Geometry™, these transducers also incorporate a copper shorting ring that is imbedded in the pole piece at the precise center of the gap and in close proximity to the voice coil. This ring results in a reduction of third harmonic distortion and a reduction of voice coil inductance, which improves the transducers' transient response.

JBL 2242H 18" Maximum Output LF Driver 8 Ohm
JBL 2242H 18" Maximum Output LF Driver 8 Ohm is rated 5.0 out of 5 by 3.
Rated 5 out of 5 by from JBL2242H behaves better with time to work it inI bought two JBL 2242 five years ago and play them 24hrs per day and they are just now able to create usable information down to 17Hz being down 10db which is easily equalized to bring the drivers output flat to 20Hz, it is also important to know that I have the 2242H's loaded in a 14ft transmission line that is 78inchs high and 30inchs deep while being 20inchs wide with one bend in it half way. The sound is unbelievable with it being tight with intense impact, not muddy at all, my whole house shakes which is audible all the way down the street with all the windows closed and several feet thick snow. The police have been here many times because people say their house is vibrating and it makes it difficult to hear their TVs, the law in Toronto Canada states that between 7am and 11pm you can make any kind of noise along as it is not deliberately to bother people, then the charge is Public Mischief, but playing music or jack hammering outside someone's windows is perfectly within the law.

Rated 5 out of 5 by from excellent wooferA woofer of this calibre is certainly not for everyone but if you are willing to experience high def. bass this is an excellent choice. Speakers are like guitars , some guitars are very cheap and some guitars are very expensive but they all sound like guitars. The difference is in the discernment and the level of committment and how much you are willing to pay. I have owned a pair of these for a while and when properly set up they are nothing short of incredible!

Rated 5 out of 5 by from Incredible wooferI replaced my excellent 2241 with the 2242. The 2242 brings a tighter sound -similar in fact to the audio characteristics of the 2226- than the 2241 more rounded bass. The more powerful motor helps better control the moving mass. I find this woofer more versatile because it can be cut slightly higher. Its clean powerful bass are spectacular and the amount of information breathing from the upper bass register makes for very realistic ambiance.

WHAT WOULD OPTIMUM SMALLEST SEALED ENCLOSURE BE

IF I WERE TO MOUNT A PAIR OF THESE JBL 2242H 18" Maximum Output LF Driver 8 Ohm, Brand: JBL Model: 2242H, BACK TO BACK LIKE THE Dayton RS1202A 1000 Watt Dual 12" Subwoofer System Assembled Brand: Dayton Audio Model: RS1202A, IN A SEALED CABINET, STUFFED WITH Acousta-Stuf Polyfill, WHAT WOULD THE OPTIMUM INTERNAL VOLUME BE IN ORDER TO YIELD THE DEEPEST HOME THEATER EFFECTS FOR MOVIES & WHAT WOULD THAT FREQUENCY BE?
Asked by: ALK53
This particular driver is not optimized for sealed alignments, nor is it geared toward home audio use. For one driver, the manufacturer suggests a ported enclosure of 5-12ft³, tuned to 30Hz or so. With two drivers in the 5.0ft³ enclosure, you would need 2 ports 6" in diameter, each about 27" in length to achieve that 30Hz tuning frequency. This will yield an F3 frequency of approximately 82Hz. As you can see, this is probably not the best choice for low frequency effects in a home theater application. For a small sealed application, you might consider TC Sounds subwoofers. I've linked a popular choice below for your convenience.
