    Probably only a curiosity, but I have a new-to-me Sparkle Blue - cabinet only. Apparently the actual cabinet size varied - a bit larger in the Kustom 250 line, vs the smaller Kustom 200 product line - and I'm trying to figure out which series is this box.

    Anyone know the actual cab' sizes for the two versions?

    Truth is I already have D140's lined up (*Selling these Guitar Speakers), so ... just a curiosity for my provenance (smily face)

    Crappy Pic, and TIA !

    man, why risk vintage D140s on bass? or is this just to complete the collection and sit in the house looking cool?

    why not put in something modern that's way beefier (and the right tuning for the cab of course) so you can use the cab without fear?

    My bad - I said D, I meant K140; with two, I should be good for 3-400 watts. That was for the vibe - I know that speaker (at some level) - had this rig in the early 70’s with D140 - long gone, but I’m not wed to them. Always resale value

    I really hadn’t considered new drivers that are better suited to the cab - back in the day that was burgeoning technology.

    what have folks upgraded to?

    You can tell if it’s a 200 vs 250 series by the grill. All solid black grill is 200.

    And they never outfitted 200’s with K140’s.

    i could see if you were powering it with like an ampeg V4 or something in the jam room, that would likely sound pretty good. i'd be scared to use a 300w cab live with a modern 800w bass head though, one stray transient might be the end

    and it’s an all black grill, afaik, so Series 200

    But they did D140’s, and K is a reasonable alternative - agree?

    I hear ya, and I don’t know (lol) … plan was to use as a show piece in a show band, and push it until the cones start to cry - then let the house add whatever else they need … probably a QSC 1804 w/ 600 @ 8 ohms … so short of a session with John Bonham, I’m probably good.

    but … what alternative speakers have you heard and liked?

    They did indeed do D-140s back in the day, and they sounded pretty dang good, IMHO. And yes, the K-series is a 'plug-in' replacement. It's the same driver with a 'Kapton' plastic former for the VC.

    Edit: The 1804 sounds like too much power for a couple of K-series. Plus, I'm guessing these are 8-ohm drivers, so a 4-ohm total load, yes?

    Nope - 16 /2 = 8 ohm cabinet.

    I bought two used, one seems "workable" at 16 ohms - I'm having the other re-coned there. Hopefully the "workable other one" will last - taking some chance with it, but seem an acceptable risk.

    bass (D-std tuning) … and, ok, some exaggeration, but yea, push ‘em occasionally - although that speaker naturally has a sweet sound, especially when a couple are paired. 4 is a better number of D(K)140’s, but two is all I plan.

    PS: not vintage, reconed

    Sidebar question: I was gifted a Kustom 2x15, non T&R just a plain black vinyl/Tolex and the model number just says 2 x 15 and a SN on the ID plate on the rear. Is there a site that shows what these cabs are in terms of drivers etc? I've had a look but I think my search-fu is not working so well. TIA.

    these being old-school JBLs they're pretty efficient right? a lot of noise with not much power?

    my first instinct is a 300w or so bass amp would be about right then, i think that would let you push them a little without so much risk of letting out the magic smoke. so like a typical 4-500w at 4Ω head, leaving you with 300-some odd watts at 8Ω

    Not especially efficient, about 97dB or so, or average for a 15" pro driver, low power handling and low Q/high Vas.
    I've owned quite a lot of these and don't see a reason for the mythology around them. There are better modern drivers especially for the elevated prices the vintage units bring. Unless you can measure them thoroughly, it's hard to know if they've been abused or not and whether they're to spec. If they've been reconed and it's not factory, they're not worth much at all.

    hmm

    yeah, i have to think a pair of eminence kappas or something would be a much better bet for fearless live use, a lot more performance for a lot less money

    I’m open to suggestions - alternatives tried and true in this cabinet.

    If this cabinet is truly original, that means it was designed in the early 60s before Thiele and Small came up with the math for correct porting. I would get modern drivers that are optimized for this enclosure. That will get you much better performance and reliability.
