Speaker companies with a focus on parts quality and measurements


Researching my next upgrade and am looking for good price/performance ratio with high quality drivers and public measurements. Currently using a pair of Chane A1rx-c bookshelf with a Rythmik F15 sub, and I'm actually quite happy with this setup. Right now I'm primarily looking at Ascend Acoustic's sierra-2 or something from Philharmonic, but I'd like to know if there are similar companies that I'm not yet aware of.

Both PBN and Shahinian are pretty accurate, based on what I've heard and talked with personally. I would also recommend Defiance Audio and, of course, Devore.

Personal bias, but Reference 3A are beautifully matched in terms of price to performance. As are Acoustic Zen Adagios.
You should watch R Vandersteen U-Tube video on pistonic motion.....real science about how driver cones behave ... or not.
He has been working on time and phase accuracy for decades, which some have just discovered...
