    So I just bought a V4B and I'm looking for a suitable cab to go with it. Preferably I would go for 2 seperate cabs including at least one 15" but unfortunatly I cannot afford this.

    Luckily I stumbled across the following two cabs combining my preferences. Both for sale in my area and for a reasonable price.

    Ampeg SVT 1540 HE (4x10" + 1x15")
    Ampeg SVT 50 Isovent (2x10" + 2x15" folded horn)

    I'm planning on using them with just the V4B so no bi-amping and I know they're both heavyweights. Who has experience with either of these cabs and could tell me something about the match with the V4B?

    Any help is much appreciated ;)

    Those are the two worst cabs Ampeg made. No used 410he's or used 810e's in your neighborhood?

    Care to elaborate about your bad experience?

    I used a 1540 for a gig a couple of times, plenty of loud (with Mesa Bass 400/Ampeg SVT 3 Pro) and nice sounding cab. :bassist:
    No experience with the Isovent cab...

    I owned a 1540HE, and it was terrible (picked it up in a trade).

    To me, it just sounded like ass. Could not sell it fast enough.

    No experience with the 1540. I like the Isovent. Sounds good. That's the most important quality in a cabinet to me. Heavy though. I know you expect a "heavyweight" but really, surprisingly heavy. It looks a little bigger than a 4X10, so you may be surprised how surprisingly heavy.

    Some people like the 1540he. I'm firmly in the "worst Ampeg cab ever" club. Absolutely hated it.

    Go grab a used 810e for like 500-600$. I've even seen heritage 810s as low as 750$ in GCs used section.

    Both cases are cabs with mixed drivers, and no cross overs. You end up with a miss match in power distribution with the 410 and 115, which is a horrible combination regardless if the speakers are in the same box, or different ones.

    Power distribution is miss matched
    Phasing/dispersion conflicts


    At least they dont share the same air space like the Mesa Powerhouse 1000/1200.

    curious as to why you're set on having at least one 15 in the set up. looks like you play in a heavy rock band... the 8x10 is the industry standard.

    Also terrible.............

    You MAY think your getting a 2X15, but it only has the output of a single 15.

    Thanks for the useful info!

    Read a lot about the 15" blowing up in the 1540HE, probably as a result of the mismatched power distribution. A friend told me he owned a isovent but it got way too undefined if you werent standing directly over the 10's.

    I might go with two separate cabs afterall. Probably go for a 410 HE (though used ones only seem to be able to handle 200w) and hold off the 15" for a while (or go with the 410HLF which seems to have enough lowend on its own).

    As for why I'm not going with a 810

    1. 410 should be loud enough for a while (is there much difference in tone?)
    2. I can't afford a new car ;)

    SVT-410HE and SVT-410HLF are vastly different designs. Looks aside, they have very little in common. HE is 8 Ohms, thick/rich in the mids, rolled off in the lows, sound much better in a mix than alone. It is not so sensitive to different amp voicings, IMHO.
    The 4 Ohm HLF has big lows, slightly scooped mids, can be harder to make work in a dense mix and since it has wider frequency range, it will also "reveal" more of the amp's voicing. It also needs plenty of amp driving it to get really loud.

    I like both but prefer HLF.

    Which ever cab you go with, the best cab to pair with it is a matching cab.
