    Yes if you're looking for glorious old school ... it is, I totally love mine but it's not for everyone.

  2. I'm picking up an empty Sunn 200s cab tomorrow. Just don't have the resource of time to build one. Been wanting to build something for years, just always something else that's priority. Even bought the plans for a BFM Omni TB, never built the thing. But I've been playing!

    There's just always a cab around to run an amp into...
  3. Another Sunn would be 2-15SH

    Folded Horn cab

    Also came as 1-15SH
  4. One of these?...

  5. Ok so I'm hearing different renditions of what speaker origjnally went with what cab... is it the E-140 or the D-140 that was originally on the 200s, and would loading in the other one be ok/not ok/"better"/"not better"... and in few words, how come?

    The less science here, the better! Thank you all for your indulgence!
  6. Apparently the E-140 won't fit in the 200s cab unless you mount it to the front of the baffle. Then you have to add some kind of minimal spacer to get clearance from the grille, which is doable.
    Also the D-140 has some more x-max to it than the E model, which was covered here I think.
    I can get it, I think, with the Ds in it, maybe he'll take my E-140s in trade...
  7. Originally the 200s came with D-140s, I'm getting confirming entries from several other sites too...
  8. Lol... answering my own questions...
  9. D-140 has greater x-max but is a little more fragile.
    E-140 takes more power but has less low-end extension it seems.

    My Acoustic 370, at 4 ohms (250 watts or so), doesn't appear to present much hazard as a speaker-ruiner though, so maybe the D- is my go-to?
  10. I've run into a Peavey 215 which appears to be the non-Deep version. This:

    Got that pair of JBL E-140s to drop into it... the Sunn 200s I've benn looking at turns out to be farther away than I want to go in my old Chevy S-10, and this one is nice and close.

    Anyone who knows the 200s cab have any wisdom here? Is this a waste of time, or a reasonable idea? Thanks!

    I'm sure this will become something else later, what I really want is an oldie Acoustic Control cab. But this needs to hold me for a few shows.

    When the Qts is 0.17 and Vas is 297L it takes a big box to get any low end. That's why they don't make them like they used to.

    Somewhere the rumor of the D-140 having 5mm of Xmax got out, but in actuality it's closer to 3mm. The winding height of the VC is not tall enough to get 5mm of Xmax using the stock D-140 VC. In fact, I don't think the bobbin height is tall enough to be able to wind a tall enough coil to achieve that much Xmax. It's been a while since I reconed these models, but I'm pretty sure of this in spite of what the internet might suggest.

  13. That's the kind of info I'm after... thanks.

  14. Found this nearby.


    Think I'll pick it up this week (bag the Peavey, posted above). I'll make a tidy grille for it, cut a couple wood wedges and have a little kick-back caster thing down at the bottom of one side.

    It's not that intriguing folded horn type porting like the Sunn, but it's a JBL... and it looks big enough to hold 8 cu. ft to me. I'll bring a tape and use the calculator app on my phone to check that out before I take it away. Only $75... that's my kinda sound, nowadays! Lol.

    There's where I'm at, at this point... pix and confetti or laments to come...

  15. This is what the E-140 speakers were in when I got them:




    Sonic enclosures, about 2.27 cu ft each. I figure I can resize the baffles for an appropriate 12 or 10 down the road. They're certainly a handy size.

    Be sure it's plywood (I've seen them in various materials), it looks like a 4648 LF cabinet (cinema series) but they did make a 4638 which was shallower. There should be a crossover or biamp connection plate on the top right side (not the back) looking at the front of the cabinet. They were intended for installation behind the screen, there may be mounting hardware on the top for the HF horn bracket. They were also sold to be used as subs in small theatres, but more often we saw 4645 cabinets with 2245 drivers (foam surrounds, I reconed maybe a couple hundred 2245's as 2240's because the foam deteriorated. My client owned a cinema chain with about 350 screens)

    This cabinet was tuned for 2226 drivers, the tuning is likely to be considerably different for the D140's. You may be able to get away with closing up one port for D-140's but you need to run the numbers.

  17. Mine are E140s, don't know how different specs are, but I see a lot of either talked about in similar context. But that's good to know, I'll keep it at the forefront when I go see.
    Thanks for chiming in.

  18. Yep, heard these. I did take the opportunity to listen again though, it's interesting to get inside each sound and walk around in it a minute.
  19. I've had a K140 in a Joe's TL-606... two of those would be my answer to all things speakerish...
