    117H kit, 116H basket vs 166

    Bobco, the question may have been obscured by a missprint so that you meant 117H and 116H, which appear similar, including variants of the 116h which were used in 4408, 4408A etc, all have 2" voive...

  3. S4S

    I purchased two of these sub transducers, but missed the backbox, which is about 75liters, and appears to be sealed. 88dB and -6@20Hz, high quality, but completely system engineered. Could I use...

  6. Midrange 8" transducer

    I have been listening to 2250h in AM6200 cmcd horns, and J models with a tight backcan ring without the horn, and they are both wonderful, JBL use them 300 or 400 up to 2100 Hz. I think 2168 is...

    Speaker placement

    Studio 590 are wonderful modern JBLs. Your small room appears to have reflective surfaces, which can muddy the sound, and speaker placement changes could help, toe in, for instance, drapes and...
  8. 121a replacement for ultrabass

    This thread has hinted at car subs, for which JBL has an unbeatable reputation, but we seem to shy away from that, and not merely for the 4 ohm (usually) impedance. Please allow me to suggest the...

    Someone may vouch for mix and match

    The wonderful LE14A was matched with LE 20 in L99 and LE 175DLH in 101, and those two ways were limited solutions for bandwidth. Later JBL mid/high transducer pairs coupled to 10 and 12" exhibited...

    LE14 as basis for threeway

    Apart from 4 way L250, I would consider N112 in a slightly larger box, maybe 60 or 70l, tuned mid thirties. That crossover is used for LE10 in L96 and 128H in L112 and L150, each near 14A's...

    Alternatives for S7 load in C50

    Mike, I have a similar problem in an Olympus, curiously also C50. I have tried PA 15s with the LE85, but do not have an LE 15, 2215, or 2235. I tried 2234(early Olympus is about 6 cubic feet,...

    Creative Frankenspeaker

    BlDozier, you often pose perplexing questions. Obviously you know the 8" LE8T (and most JBL 8s) use 2" voice coils and .85 T magnets, while the 2108 uses a 3" alnico motor. So you might plan to...

    what he said

    The 2123 in a sealed mid box goes down to about 300 Hz. Choice seems to be in low frequency transducers 2235 and 2245, each the best, but the 18 needs almost twice the vol.(140l vs. 240l) so your...

  21. AM4315 same box and horn as 6315

    I just found this old thread, and hope others have investigated these speakers. The mid power unit, the AM4315, uses the 2033H bass in the same volume as the 2226H in the hi power AM6315 and the 2265...

    mms

    the 2108 mms is 20grams, the LE8t mms is 16 grams; these moving mass figures include voice coils and, I think, nearly half of surround and spider mass
  23. 3.5 milliHenry

    Kelossus, one indication of the upgrade 104h series offered over the LE5s was the deletion of the little inductor which tamed an output bump in systems like L110 and L86, 96, 112,etc which utilized...
