While I have voiced enthusiasm for open baffle speakers, this does come with the warning that dipole speakers often do not go very deep in bass response because the opposite phase front and back waves tend to cancel each other at progressively increasing amount as frequency goes down. This is true of dipole panel speakers as well. I am not a bass freak so this is not as big a deal to me as it might be to others.
The original Heil AMT speaker had a dipole AMT driver but the bass was delivered by a more conventional woofer that was not used in dipole configuration. That speaker had serious problems with the two drivers not integrsting well. That problem persisted with the new iteration that is out now. But, other builders have been successful matching heil drivers with conventional drivers so it can be done.
a 3 way design speaker with the ESS Heil type sound
I have tried Klipsch RF-7 lll, ADS 780,880, 1290 ll, 1590 ll, ESS 3 ways with HEIL, and Daedalus Speakers. I still own all of these. Is there a speaker with the bass slam and dynamics of Klipsch RF-7 lll, and the midrange and tweeter sound of ESS HEIL, that is as beautiful, efficient, and easy to drive as Daedalus Speakers??
I have VPI prime. AT 760 SLC mm, and Sumiko Blackbird HOMC. Phono preamp is Ayre P-5xe. I run balanced out. I also have a Graham Slee Accession.
I use my Line Magnetic LM-515 CD player with balanced outputs. I like the sound. Great bass and extension. No fatigue with tube buffer output.
I have a Marantz SACD 30n for streaming, and SACD use. The Marantz is definitely a weak link.
I have Simaudio 740P balance into Simaudio 760A.
kinda dry sounding. Thinking this magic unicorn speaker (if existed) would solve my problem.
or do I need a good tube preamp??
looking for advice

That configuration is darn close to my own custom built setup:

Certainly worthy of some links to pics. Wow, those are some serious AMTs! Very interesting open-baffle designs. Others coming in April 2025 eh’. Very Cool. https://arionaudio.com/speakers/ Way more than a 3-way, in a line array, huge AMT sound. Holy cow. :)

@larryi , the AMT 1B’s had a single driver on the face facet with a matched diameter passive on the back... If the bass seemed out of phase, it really was the room. And the means to DSP the space with white noise that likely made the neighbors think our vacuum cleaner had been plugged into the wrong plug.... The issue with AMT drivers ’in general’, imho, is matching the response speed of the bass drivers to keep up. My approach is to have a ’mid/high’ 6.5" bass unit(s) and dump the low bass into a healthy sub or 4..... Like the ’look’ of the Line 10’s over the Cinnamons’......the latter would be a tough sell to the sig other.... |
