A couple of weeks ago at the Midwest Audio Fest (pretty much a horn speaker and tube amp fest) in Ohio I heard Bruce Edgar's Titan Horn system with his Seismic sub. This is a folded basshorn, a 35hz hyperbolic flare. It is a monster standing 72" tall by 32" wide and 24" deep. It uses an 18" PAS driver and a HSU amp with EQ so that the unit is flat to 20hz. This damned thing made the most realistic low bass I ever heard, it has lifelike dynamics and not a trace of overhang or distortion, not a trace, transients to die for. The utter clarity of this horn makes one realize how much grunge is passing for bass with most subs. This sub makes fewer compromises than any I'm aware of for a commercial product. Up till now the best I'd heard was a rig with a pair of Servo-Drive Contrabasses but the Seismic easily bested them. Price is $1000 in unfinished MDF, $1500 in maple plywood and $3500 in a furniture finish. At $1000 for the unfinished version the price is super-cheap considering that nothing I ever heard performs as well. Second best sub at the show was Mike Bates DIY subs; 2 refrigerator sized boxes, each with 4 15" JBL 2235s in a push-pull configuration. This was matched to his mains, each using 2 Altec 416 15s in vented boxes with Adamson compression drivers on 250hz SB horms for mids and TAD 4001 on SB horns for tweets. Cool. He blew an amp and then ran it with the superclean 1963 15wpc Fisher SA-100 tube amp I picked-up at the swap tables for $275. With the Fisher this rig was hitting 120db no sweat. Just thought you guys might like to know what the crazy hornies are up to.
