Sonic 15 Enclosures??

Discussion in 'Amps and Cabs [BG]' started by Count Bassie, May 27, 2018.

  1. I'd like to reference this thread: Anyone heard of Sonic Bass Cabinets??
    ...and follow up with a query:
    I bought the cabs pictured below, loaded with JBL E140s. The cabs are very small, nearly half the recommended internal volume for those venerable JBL 15s. But I'm reading that perhaps these cabs were sold with those speakers purposefully?

    Does anyone have knowledge of this, or of the origins of these cabs?

    The internal dimensions are:
    And are shelf ported:
    2"H x 5-1/2" D

    Thanks for your time!

    It's 30 x 24 x 18. It's a bass monster!

    I had one for a while that I bought in L.A. in the mid 1980s to go with a used Walter Woods amp I bought out there. Was only used for home practice; I think it had whatever stock speaker was in it at the time.
  5. Right, sounds reasonable, esp at that depth- 18" is the depth, I'm presuming here. 30" high... yes?
    Can't figure putting a speaker requiring 4 cu ft of volume into a box with 2.27 cu ft... 12" deep... I wonder what driver it originally came with.
  6. The Sonic website is decidedly sparse in the info they offer, and not too good at communicating, so far.

    Those cabs are tuned in the vicinity of 75Hz, pretty useless for bass.

    You are welcome to come up and try mine. It's inside my house as I have been using a pair of 12s.
  10. Where are you at? Also yours is an 18, right? I'm trying to finx, maybe even build, at this point, a boxes/boxes for a pair of JBL E140s.

    I bought a used empty one about seven years ago and put a Carvin PS15 8 ohm speaker in it. It's a nice compact size and was great for small jazz gigs.

    Probably not too much different than a Bag End S15, IME.

  13. It seems to be similar, yet there's some lows coming out of the Bag End. Porting and the right driver I guess.

    I thought the two S15 cabs I had were great, until I tried an EV B-210. That made me realize how much bottom end there really wasn't coming out of the two Bag Ends compared to the one B-210. I sold both of the Bag Ends and bought a second EV cab.
  15. Tools for jobs I guess. I sold my S15-Ds to an upright player who was touring with Bill Kirtchen, the guy who wrote "Hot Rod Lincoln". They sound unbeatable in that context. My little Sonics might too, but not here... I mean they're cute and all, but...

    I believe if you use a actual QB3 alighment for JBL D-140 you do get a very small enclosures around 2 cubic feet and yes some ridiculous high 70s tuning to get a butterworth response.

    So maybe it is a actual " TS" alighment and Sonic had good intentions. but anybody who knows anything or actually owned JBLs would instantaneously burst into laughter and ignore a QB3 and many other assisted alighments for older JBLs
