Those interesting cabinets/amps Ampeg made in the 1990's

Well you gotta hand it to Ampeg, they certainly made a wide variety of different and unusual speaker cabs and amps back in the 1990's/early 2000's.

I cannot find my Ampeg brochures from back then but just a few I recall from memory:

1. Isovent - these apparently don't get much love around here but the concept was rather interesting. IIRC they had two 15" drivers arranged in an isobaric configuration, then a pair of 10" drivers and a horn up top. Pig heavy of course but interesting nonetheless.

2. An 8" x 8 cabinet. Maybe others besides SWR made these back then but I guess it got you a lot of the fridge vibe without quite as much weight

3. A 6.5" x 8 cabinet, the SVT-806HE - I actually own one of these and love it. Eight 6.5" polypropylene drivers in two chambers with a tweeter (you can bypass the tweeter with a jack on the back panel). It's like a 3/4 size fridge (even the logo is downsized) but weighs about half as much (85 pounds).

While not a great low B cabinet this thing has the kind of transient response you have to hear to believe. I use mine with a B2-R head (so 350 watts into the four ohm cabinet) and it's a great, very loud sound.

4. SVT-150H head. This was the transistor amp section used in the B3 series combos only in a small head that looked like a classic Ampeg. This was designed to pair nicely (in size and depth) with the SVT-806HE.

5. B2 combo with four 8" drivers. This thing was HEAVY (like 100 pounds) but you could also pair it with their 4 x 8" cabinet to make an 8" x 8 combo stack that put out 350 watts.

6. B3158 combo - Another neat one, had a single 15" and a 8" driver as well. Was biamped internally with a balance knob to pan between the two amps/speakers.

Was also pig heavy but had rear wheels and a handle to move it around

7. B328 Combo - I wanted to buy one of these back in the day but could never find one new and the used ones I checked out were overpriced and not in great shape.

150 watt amp section from the B3 line, two 8" drivers and a horn in a tiltback cabinet.

Also like all the Ampegs from that era kinda heavy, 58 pounds I believe

8. SVT-350H Head - this was not all that weird but put the B2 amp section in a conventional looking SVT head enclosure. Big brother to the SVT-150H

9. I cannot remember the model number but in the catalog they also offered a 2 x 15" folded horn cabinet. I think it weighed like 200 pounds!

10. PBC-228 combo (this came out around 2001) of which I own. A neat concept, two 8" drivers and a 200 watt Class D amp section. Poplar wood and Eminence Neo drivers used for the cabinet so it weighed only 31 pounds.

The amp section was sort of a mashup of the PB-800 (dual channels, sweepable mids) with the back panel of the PB-250. Oddly though rated at 200 watts into four ohms (what the amp was wired for, no extension speaker jack) even though the PB-250 was rated at 250 watts into four ohms.

Great concept that didn't really work out. I bought mine as a blowout sale because it was cute, small and a bit of an oddity, but it does not get very loud and does not have a lot of low end. But it's a cool little amp

11. Various cabinets with Coaxial drivers for some of the speakers instead of speakers and a horn. I can't remember them distinctly but I think there was even a version of the SVT with this setup.

12. The "Pro" series which were versions of existing designs only I think they took more power and they certainly weighed a lot more. I believe the Pro version of the SVT Fridge was like 200 pounds.

13. B1-R: I guess since the B2-R was one of their more popular amps and sold for $499 back in the day, they decided to put the B3 amp section (150 watts at 4 ohms) into a small rack head. Not sure how many of these they sold

14. Preamps - the SVP-Pro which was highly regarded (I own one and I love it) but they also made a "Billy Sheehan" version which was drastically different. I think there might have been a third preamp as well.

So that's the ones that I remember, feel free to chime in with the ones I left out.

Anybody else like me own any of these interesting products from that era?

I gotta believe one thing that sent SLM into bankruptcy and the arms of loud was just too damn many products. One of the versions of the brochures I have is a foldout one, must be 50 different products!

They have old product manuals online under the support page. A lot of weird cabs are captured - the isovent, 808, 48, 806, 50HE, 1510, 1540, etc are all there. Some of the other stuff you mention as well.

Don't forget the 1540 cabinet-A fridge cab with 4 10"s on top and a 15" on bottom.
Of course pre-Talkbass I thought this was the ideal cab.
I still dug it running it with each half split into an Acoustic 370 head (which could be run at 2 ohms).
I did have to recone (finally replace) the 15" more than once, but whatever I had put in it held up until I sold it.
 
Acquired this new in 1992; Ampeg B-1 combo. Tube pre-amp, solid state 150 watt

power amp, 12" Eminence speaker, mid-range driver, ported cabinet, removable, rack-mountable head. All original. Playing gigs through it regularly to the present.
 
I kinda want a B1 combo, or maybe the head version, but I've never actually seen one.

All the weird cabs Ampeg made are interesting, but most are so heavy to not be really worth it....Even the 8x6 is over 100 pounds! Might as well get an 810 at that weight.

Here that "Folded Horn " cabinet, it was the V4-B, what is interesting, is it pushed the sound out through a small rectangular opening, the issue with that cab, was it was hard to hear, when standing next to it, but 20 or so feet out/away, it would liquidify internal organs, I read, they used this design to maximize the 100 watt V4B head output, sound wise, this was back in the day when 100 wat amps were common, and a SVT head, was one would dream, of having, times have changed
 
#1, Isovent - I owned one of these briefly, paired it with my Mesa Buster! 210 wedge combo. The Buster! atop a 410 sounded better. I was underwhelmed and let down by that cab.

#2, 8x8 cab - never owned one, but I love old Henry the 8x8 cabs.

#5, B2re 4x8 combo - saw one for sale locally but didn't get it, wish I could have at least tried it out.

#12, Pro series cabs - I found a fridge (PR810h) that is owned by my church now. 220lbs of a beast, sounds good, I've posted pics in other threads. I'll add a couple here.

#13, B1-R - love the idea of a 1u, 150w rack amp as a backup but the preamp side was not as clean as I would have liked so I eventually sold it. Missed out on a 112 combo of the same as someone else has posted.
