Fair enough! It certainly all looks intentional and I guess they figure the world doesn't need more "flat on axis smooth directivity" studio monitor-like speakers. And I have to give credit where it's due for bass extension and done in a similar way that KEF does to manage room gain. I just find the midrange and treble swings to be pretty aggressive to the point that I wouldn't consider these even at half the price.No. The Epique woofers and (new model) Reference Series tweeters are pretty recent models and best sellers.
No. DIYers know the designer, he participates to a limited extent on some of the DIY forums, takes Spinorama measurements and uses VituixCAD.
The speakers generally have good reviews but that doesn't mean everyone is going to like them. They definitely don't measure flat enough for a lot of ASR members. I get the feeling that PE knows it's customer base just fine and it's goal is to make money selling speakers to that base. (And ASR members aren't the core of that base.)
Simple Hoffman's Iron Law. The Epique E150HE-4 woofer can reach crazy-low in a small enclosure (F3 of 32Hz in ~0.40 cf). Raw driver is 83.3dB sensitivity and with baffle step loss the final speaker has low sensitivity. But has huge xmax so give it a bunch of cheap power.
That said, I can't dispute a "love it or hate it" strategy in a crowded market, if that's what they're doing. Those that want this sound signature don't have a ton of high quality and affordable options.
