    Actually, back in the day before it was purchased by Tymphany and went to China, the XT25 from Vifa and made in Denmark was about $55. This would have been about 2006/2007. The Chinese manufacturing under the Peerless (V-Line) badge dropped the price to 20-30 clams.

    If you look up Dunlavy or Duntech speakers you will find thr Vifa XT 25 in several $ 20, 000.00 dollar plus speakers.

    The woofer appears to be the Morel TiCW 958Ft.

    This speaker doesn't seem that outlandish to me . . . for the high-end market. Sounds like they could use a better crossover, though.

    My wife likes to watch The Price is Right on TV between 11:00 AM and noon, and I often sit down and watch with her for a short while before I eat lunch. Last week one of the prizes a contestant was trying to win was an audio system from PE featuring the Epique CBT24K Line Array along with other audio goodies.

    The Alta sure looks (appearance) nice. The design is interesting in that it sounds like the morel mid and two Dayton’s are all sharing the same circuit.

    Looks like Alta uses Dayton’s RS drivers in some of their other designs.

    Cellulose acrylate. Although magnesium silicate sure sounds fancy!

    They were using Dynaudio drivers. Also the Endeavor design uses Dayton woofers, HiVi mid, and a Vifa tweeter.

    Same issue also reviews a Totem Acoustic Signature One where they openly spec the tweeter as SEAS, but don’t credit the woofer, which appears to be the new Dynavox 6.5” woofer. Cone material listed is allegedly different, but it sure looks the same to me, right down to the part number molded in the surround.

    I read the review, woofer is a Morel as well. Of course the overall review is highly positive. I think the measurements are horrendous, however JA doesn’t seem too off-put by them. They are a dipole in the mid and maybe I don’t know how to interpret this as well but the fr graph shows numerous 5db variations with a total variation of 15db. I don’t fault the drivers, perhaps crossover design, measurement techniques, and dipole use all factor. Better have a good amp, phase is outside 45deg in three places and impedance is at or below 2 ohms around 100hz and 200-300hz.

    I’d share some pics but my phone only makes giant files too big to upload.
