Lawrence Audio Cellos use the Heil for the Treble and Midrange. They are extremely good!! They are relatively unknown here in the states. They have a nice website and will shortly be reviewed. I have no affiliation and just had the opportunity to hear one of the few pairs in the US.
ESS and Heil air-motion tranformer - any thoughts?
These seem like interesting speakers, has anyone on this board had any experience with the ESS line of speakers?
A.M.T. description:
"The Heil diaphragm, made of soft, quiet mylar to reduce background noise, is bonded with conductive aluminum strips. It is equivalent in surface area to a conventional cone type eight inch midrange driver, but is accordion-folded down to a compact one-inch band for better point source dispersion. The low mass diaphragm is suspended in a massive magnet structure concentrating an intense magnetic field around the diaphragm.
When a signal passes through the aluminum strips, the bellows-like motion of the folded "pleats" squeezes air out five times faster then the air motion of a conventional cone driver. The virtual "instant acceleration" provides high definition, crisp transients, and overall spaciousness with superb dynamic range. This type of performance distinguishes the heil from all other transducers."

Dawgbyte, It just so happens I have a pair of ESS MT with Optional sub-woofer bass cabinet the made for the ESS main cab FITS into. I Bought ALL NEW BACK IN THE DAY!!Late 70's The sub woofer is a KEF Rectangular 6 X 12" floor firing. It's set-up for Tri Amp operation only. How good are they? 15+ years back. I hauled them to buddy home who had just bought a pair of Sound Labs Electro's Their were (4) of us. We did blind. TEST both were hooked to ARC-D150M (Mid to Highs.)(2) ARC 120 for mid-bass & woofer on my EES MK11 all thru ARC-SP15-2 Pre-amp. Test record was a Telarc: Grand Canyon Suite. THE TEST(4) chairs turn backs to speakers. His wife JOB turned the balance L to R as the Pre was in Mono, playe SAME 15-SEC track over/over. We all wrote down. L is better. or R is 5 plays. 3 of the 4 picked the ESS for best upper Mid range to Highs. All 4 including myself picked the S-Labs detail in lower Mids to upper bass hands down. But the EES SUB had punch all could feel the standing wave on our backs. No of us were told which speaker was L or R. Hope that helps your question. Tube444 |
They came out with some headphones that uses these Heil air-motion tranformers, the new Obravo HAMT-1's for $1500 that sound as good as.. Reference Floorstanding Speakers!! http://www.absolutesounds.com/pdf/main/press/Obravo_HAMT-1_HFN_JAn15.pdf |
