Hey all, My full story first. I have an Acoustic 370 amp, early 70's production (I think), and when I bought it this year I had a cab maker (around 30 years in the business, read some pretty good rep, too) build me a 2ohm 2x15" with two 4ohm drivers that he makes himself. I was shown the whole process of production. The guy basically takes an old East German Vermona speaker, leaves only the basket (which, I was told, is of surprisingly good quality) and everything essential to a loudspeaker - diaphragm, coil, etc. - is assembled by hand from parts (not East German, though). Fair enough, I thought, and went for it. Knowing the power, possibilities and reputation of my Acoustic 370, and wanting to push heavy kickass vintage early '70's road-worn solid-state USA air with a lot of deep end, I specifically asked to wire the cab for a 2ohm speaker load. That, by the way, is why I turned in the first place to the guy instead of going for a 4ohm or 8ohm factory made cab, as I couldn't find anything wired for 2ohm. So, the result is a 60kg cabinet with no wheels that my bandmates aptly nickname either "The Bitch" or "The Pig", when one of them has to help me carry it around. We play rehearsals in a damp basement of a building on the grounds of what used to be a factory complex making TV's. Every time we have to grab our gear and carry it up to our band's van, we have to carry "The Pig" up (and later, down) a very narrow and steep flight of stairs. It then takes up about half of our baggage space, and we have to carry it around at the venue. And believe me, it is a pain to move. Apparently, as one of my mates puts it, the only thing worse is an Ampeg 810. After playing for some time during rehearsals and live shows I have noticed that this combination, the Acoustic 370 and this 2ohm cab sounds rather... weak and dull. Especially during rehearsals. No matter how much I tweak the amp's settings it seems that I can't get the sound that I like, and the whole thing seems dull, like if it was choked, or something similar. The cab is definitely pushing a LOT of air, so much that when I stand close to it, on lower registers it feels as if I put my hands against a small cooling fan, and the Volume is barely around 1. There's that Acoustic legend for ya! Also, every time I hit a note there is some weird distortion going on. In the best description that I can give you, it seems like there is a "second channel" in the cab, you can hear the note from the bass clearly, and at the same time there's something that sounds like the same distorted note coming from "under" the clear sound. It's weird, I know, but it's not a problem with the amp (I'll get around to it in a second). Perhaps, if anyone's interested, I'll try recording exactly what I mean with my Zoom H4n recorder next time we rehearse at our space. I believe that one of the speakers is shot, or maybe something with the wiring. In the meantime we recorded at a studio... and honestly, I gotta say, that time I was very satisfied and content with the setup that I have. Hopefully after we mix the material it will sound good. In the end, given all the problems I'm having with the cab - sound and transportation-wise, I've decided to look for something else. Upstairs from our cramped and damp little cellar is another rehearsal space/studio, and I took their US-made Ampeg 410 (I believe it was the HE, Classic series), hooked it up and... HOLY JESUS. This thing ROCKED!! That made me think about getting a 410 speaker cabinet for my Acoustic 370. Later, as I began my research, I started looking into the 610 and 810 also. As for my existing 2ohm "Pig" - oh well, lesson learned, I've chalked everything up to inexperience and decided to move on. I could deal with the guy who built it, replace a speaker, whatever, but I decided against this kind of hassle. I'll just go with a factory-made cab. As for the amplifier, I am totally content and I really love it. I've used it during gigs with various other cabs. Some that I remember were an SWR 610, a David Laboga 610/810 (?), Ashdown 410 and various others, I loved the results so I know that my Acoustic is not the problem here and kicks ass. It's gonna stay no matter what. ---------- So, right now I'm in the market for a Ampeg cabinet. I'm specifically looking at the Heritage series, given all the positive press I've read about them. The ones I'm considering are the SVT-410HLF and 810, and a regular Ampeg SVT 610HLF. Can't find a Heritage model of a 610 around here (Poland), or maybe they just aren't made? And yes, I know that my current cab, "The Pig" is cumbersome and a big problem in transportation, and I'm still considering an 810, which is even bigger. But hey, it's an 810 and it's been my dream for a long time. I'll work out the transportation part with my band mates. Sound wise what I'm looking for is something with a lot of punchy, clear and coherent deep end. I totally admire playing such as Klaus Flouride from the Dead Kennedys ("Plastic Surgery Disasters" era; 1966 Jazz Bass, Badass II bridge, SD Quarter Pound pickups, Acoustic 150b/Traynor Mono Block amps, 2x15 cab loaded with JBL's) or JJ Burnel of The Stranglers - I believe their sound is like a runaway freight train, yet it is still very clear and coherent. I play a 2008 MIA Standard P-Bass and that's not gonna change, except for the pickups (planning on SD Quarter Pounders) and the bridge (Badass II), and in the future I'm looking forward to getting a mid-'70s P-Bass. Unfortunately I can't just get used Ampeg gear around here, unlike the United States for example. New gear only. The Heritage 410 costs around $1000, the 610 around $1450, and the Heritage 810 - $1653. I need a cab by the end of September, beggining of October - lots of new gigs coming up, and next year we'll probably be doing a new album. I'd love to simply get a 810, but I heard it's got a lot more midrange than the 410. Not really what I'm looking for, as I'd like to stay in the lower frequencies. So, for my choice of amp - the Acoustic 370 - and the sound that I'm looking for - deep bass, yet coherent and clear, which cab would you recommend? The Heritage 410, the regular 610HLF (Asian production, I guess?) or the Heritage 810? What are your opinions on these cabs? Thanks in advance and thanks for reading.
