I did a search for some of my earlier posts on this, but they were out of date, so here goes again! I'm a massive Berg fan!
Current line:
HD... 'High Definition'. This is Jim's current 'modern ceramic' line (210, 410, 112, 212). The HD 10 loaded cabs are based on the previous HS (High Sensitivity) line and are pretty similar (a bit brighter up top). The HD112 replaces the HT112ER (same driver, same box size, smoother, more organic/natural tweeter). The HD212 is a totally new box. Both the current HD 10's and the previous HS10's were revisions of the original SA (Sadowsky) 410 and 210, which were 'tighter voiced' versions designed to work with the Sadowsky tube head. He basically extended the low end a bit (with a driver modification) for the HS line, and then did another tweak and added 12 loaded cabs to the current HD line. The HD 10's are round and warm and punchy, the 12's are big and open and smooth.
CN 'Carbon Neo'. This is Jim's current neo line, and consists of a 112 and 212. Quite different in voicing from the discontinued AE line. They are punchy, mid present, nice round low end, and the same tweeter as the HD line, resulting in a smooth, organic, well integrated, non sizzly tweeter. Amazing cabs.... punchy like the HD 10's, but bigger down low, and WAY lighter. The 'carbon' part of the name comes from the 'carbon patterned tolex', and is meant to communicate 'lightweight, cutting edge.
NV 'New Vintage'. Currently, there is a new 115 with mid driver and a 610 in the line-up. These cabs are both sealed, no tweeters, and are meant to be an improvement (weight and frequency response) on 'classic/vintage' sealed cabs, while still retaining some of that unique sealed cab vibe. Ceramic, not lightweight in an absolute sense, but smaller and lighter than the classic cabs that inspired them. There were three additional cabs in the line that were discontinued...NV215, NV425, and NV412.
* Note: The CN112/CN212 and the HD112/HD212 are basically the same boxes (virtually the same size), with the neo versus ceramic drivers, and hence weight, as the main difference (along with the tonal differences described above). The HD line of cabs has a spray on finish like the discontinued AE's. The CN has tolex.
Older, discontinued lines:
HT (don't know what that stands for... can't remember
). Lots of different cabs through the years in this line... HT210, HT115, HT310, HT212, HT322, modular HT322 (HT210s/EX112s), HT112s, and the HT112 and HT112ER and probably a few more that I forgot. They all sounded a bit different, but, except for the very mid present and very small HT112, they were deep, mid polite, and very hi fi up top. As mentioned above, the HT112ER was recently replaced by the HD112, which is the only 'HT inspired' cab left in the current line-up (same woofer, same box, different tweeter).
AE 'Advanced Engineering' Jim's first neo line. Consisted of a 410, a 210, a 112 and a 212. The 410 and the original 'horizontal' AE210 were very 'tight and bright', as was the original AE112... grindy, punchy. The revised AE112b and the revised vertical AE210 had significantly revoiced crossovers that made them much smoother and more relaxed (I feel the AE210v is one of the best sounding cabs Jim has ever produced). The AE212 was VERY big down low (i.e., low end extended), relaxed in the mids, and relatively hi fi up top, so in a way, a bit like the older HT cabs.
IP 'Intelligent Power' Basically, self powered HT212, HT112 (first the original small HT112, then the larger, low end expanded HT112ER) and HT310, with 1000 watt class D/SMPS ICE power modules, and DSP (digital signal processing) circuitry that provided EQ flattening and selective multi-band compression that made these cabs very loud and quite even sounding. Required a preamp.
SA 'Sadowsky' 410 and 210 cab line designed by Jim to match with the Sadowsky tube head. Even though they were ported and had tweeters, they were voiced to kind of mimic a sealed 10 'all tube amp friendly' design... very tight and punchy.
HS 'High Sensitivity' 410 and 210 ceramic.... slight revision, update of the SA cabs after Roger discontinued his SA amp line. Still very efficient (hence the name) like the SA's designed for the relatively low powered Sadowsky tube head, but with slightly revised drivers to allow for a bit more low end meat, making them work optimally with moderate powered solid state heads. The HS line, as mentioned above, was discontinued and merged into the new HD line (which included another minor revision of the 210 and 410 for a bit more presence up top, and the addition of 12 loaded cabs)
I think that covers the waterfront pretty well.
