Two weeks ago I took a new prototype of the Acme 1x12 Neo (no tweeter) to try out at a gig. Unfortunately, we had house power problems at the gig and I spent all my time trying to keeping my head from shutting down rather than putting the cab through its paces. Yesterday, before I returned the prototype to Andy, I decided to run some A/B comparisons between it and one of my Low B-2s (Series II). I powered them with an all-tube Eden VT-300 and a Genz-Benz Shuttle 9.0 and I used my passive Precision (P/J). The prototype was 4 ohms and my Low B-2 was 8 ohms. I cranked both as much as I dared in the house. Once enough chattels start rattling, I cant tell where a buzz might be originating. The prototypes woofer, which has a sensitivity of 91+ according to Eminence, was still a little louder due to its lower impedance. Here are some impressions and some new info about Acme: - Andy has apparently resolved his delays with his mill and now has lumber cut. Some of the new Neo speakers delivered from Eminence were damaged, but that has now been resolved. He has an inventory of all his hardware and other components, and is in the process of training some of his people on construction of the new models. I think hell be ready to announce and take orders very soon. - Andy and I casually referred to the tweeterless 1x12 Neo cab as the "dumb box", a temporary nickname that obviously has no marketing panache. It will officially be called the "Flatwound" and will be the first Neo offering among the new Series III models that Andy is about to announce. I believe the Series III models will include the existing Series II models (1x10, 2x10 and 4x10) plus the Flatwound. The Series III models will all have black Duratex finishes, new handles (I think), polyswitches instead of light bulbs, no edging between the corners and new badges. - A 1x12 Neo (with a different name, of course) will come out later that includes a concentric tweeter mounted on the center dust cap of the woofer. Not a whizzer cone, but a true tweeter. Andy is testing adhesives now. In typical fashion, he has tried dozens already and has a few finalists that he subjecting to breakage, heat, cold and other types of tests. - If you purchase a Flatwound before the 1x12 Neo is available with the concentric tweeter, you will be able to buy a kit that allows you to easily add the tweeter at a later time. If the system Andy has devised works as well as it appears it will, all you'll need to mount the tweeter in the center of the woofer is a screw driver to remove the grill and jack plate. NO SOLDERING. The wires will connect with push-on connectors. - The announcement and availability of the Flatwound is imminent and its concentric tweeter stablemate is pretty close, but I have the impression the 2x12 Neos might be farther behind. - After comparing the Flatwound to my beloved Low B-2, I surprisingly decided that I actually preferred the Flatwound--though the Low B-2 is very close and is still an incredible cab. Some players, I think, will continue to prefer the Low B-2. I thought both cabs are equally deep, if "deep" means the ability to hit notes at 40 Hz or 30 Hz and not roll off 6 or 12 db in sensitivity. The Flatwound is a full-blooded Acme in terms of low end frequency response. The Low B-2, to me, has a somewhat darker and lower voicing so, from an EQ standpoint, the Low B-2 may seem "deeper" to some ears. Remember, this is on a comparative basis between two Acmes. Both have a low end as strong or stronger than any other 2x10 or 1x12 Neo Ive heard. - Through the lows and mids, the Flatwound's natural voicing is more open and even than the Low B-2 and I thought it was actually a bit cleaner, with more "presence". The Neo woofer goes down to 30Hz and goes up above 2000Hz. It sounded naturally a little brighter to me than the Low B-2 does with both attenuators set at noon. As a card-carrying old schooler, I was surprised that I liked the Flatwound a little better than the Low B-2, but I wondered if I could get the B-2s darker, even "bassier" tone from the Flatwound. A little EQ adjustment was all it took. I have a Genz-Benz Shuttle 9.0 that has a shelf-style boost from 38-67 Hz. The moment I hit that boost button, the Flatwound sounded almost identical to the Low B-2. I once thought I might wait for the "tweetered" version of the 1x12 Neo; but now that I've heard the Flatwound's wide response and know that the tweeter can very easily be added later for only the price of an add-on kit, I see no reason to wait. I'm really excited about the new Series III Neos.
