@tomic601 Infinity Systems certainly changed direction in terms of their speaker designs following Arnie Nudell’s departure in 1989, no longer producing boxless dipole speakers. The rights to the EMI drivers were also split between Harmon and Arnie, with Arnie keeping the Emit-R tweeter which formed the basis of Genesis Advanced Technologies’ tweeter. From there, Harmon tightened the screws leading to the departure of Company President Cary Christie in 1995, who continued on only as a consulting designer for another 3 years. A factory fire then destroyed much of the tooling for the remaining EMI drivers, hastening the end of the era of classic Infiniity speakers. Harmon were only really interested in milking Infinity to develop it’s own line of speakers. There used to be a photo on the internet of Harmon/Revel voicing a pair of Revel Ultima Gem’s with Infinity IRS-Omega speakers, but that photo mysteriously disappeared after I mentioned it in an Infinity thread a few years ago. So it was really Harmon who screwed up Arnie’s legacy, hastened by bad luck.
New speakers for my system
I am currently running a bi-amped system comprised of a pair of 360° dispersion transmission lines that are tuned to 17Hz and a pair of 2 ways using Scanspeak Ti HF and 6" full range drivers. The 2 ways are crossed over at 4k with 2nd order Butterworths.
I am driving them all with a pair of Classé strereo amps. The crossovers to each amp are via a DSP.
The plan is to eliminate the 2 ways and replace them with a better imaging pair of something that will not require digital filtration but will only see the digital crossover. The crossover can be at a low enough frequency, perhaps 100Hz, so there will be no significant time alignment issues caused by the digital circuitry.
Another option would be to bi-amp a single pair and replace both speaker pairs. This is hard to justify since the T-Ls are pretty effective. In fact I’ve needed to roll them off at 25Hz. They use a pair of the old Focal kevlar cone drivers (8".)
Maybe some time-aligned D’Appolito configuration?
