    New Towers-BMR Philharmonic, Revel F208, or other?

    The new HT's are 43" high, 8.5" wide, and 10.75" deep. Weight is around 55 lbs.

    New Towers-BMR Philharmonic, Revel F208, or other?

    We have no dealers anywhere. And shipping the towers to Europe would be extremely expensive and risky. They're over 90 lbs each. Shipping our upcoming HT tower would be more practical. They're due to arrive in March.

    New Towers-BMR Philharmonic, Revel F208, or other?

    The new HT uses a more sensitive version of the Purifi 8 Ohm 6.5" woofer. There is a trade-off in bass extension, but anyone who is serious enough to buy the HT for movies will no doubt have a sub(s). The box tuning is mass loaded transmission line, and there's useful room response down to 32...

    The New Advent Loudspeaker Review (Vintage Speaker)

    The New Advent was introduced to meet comments that the original was too laid back in the highs. Lacking a time machine, I can say for sure whether the sample I sent Amir was in spec, but the tweeter impedance measurement matches others that have been published. There's no question that my...

    The New Advent Loudspeaker Review (Vintage Speaker)

    Thanks very much. I had forgotten than the original came in a utility cabinet. I owned the rounded veneer version.

    The New Advent Loudspeaker Review (Vintage Speaker)

    I'm not sure that's correct. The New Advents, which Amir tested and I worked with, had elevated and generally unpleasant highs, and the only change in cabinetry was the option of a less expensive finish. AFAIK, the original cabinet, shown in the picture, was never improved upon.

    New Towers-BMR Philharmonic, Revel F208, or other?

    Thanks for the research. The Audioholicsfull-range measurements for the tower show pretty much text book behavior off axis, assuming you think very broad dispersion is a plus. I'm not sure spin data would add much.

    New Towers-BMR Philharmonic, Revel F208, or other?

    This isn't my area of expertise and I don't want make anything like a definitive statement, but my experience has been that James' ground plane measurements usually don't match all that well with the factory specs. Here's his measurement of the big hog Perlisten S7t

    New Towers-BMR Philharmonic, Revel F208, or other?

    I've never done his experiment, but I'm very skeptical. My nearfield measurement matched the simulation exactly.

    New Towers-BMR Philharmonic, Revel F208, or other?

    The mic was at most 1/4" from the woofer dust cap when I did the nearfield measurement. I really doubt there was any bleed-through from the port, or vice versa.

    New Towers-BMR Philharmonic, Revel F208, or other?

    Well, I have a taste for science and accurate sound reproduction:) A good bit of work went into the tower's box tuning. I always call on Paul Kittinger to do this part of the design work. He uses extremely sophisticated transmission line design software that optimizes the location of the...

    Why are there so few omnidirectional speakers?

    I'm not sure there is any "correct" radiation pattern. Dr. Bose thought he provided it with the 901's, which were sort of omnidirectional. His calculated the ratio of direct to reflected sound in a typical concert hall (which--I know--doesn't exist) and tried to replicate that ratio with the...

    KLH Model 5 review and measurements by Erins Audio Corner

    For what it's worth, it didn't get any first place votes at the recent Arizona Speakerfest.

    Attempts at Circular AMTs or Ribbons?

    I'm not sure what directivity issue is being referenced. The main problem involves woofers, not tweeters. Obviously different sizes and types of tweeters will have different radiation patterns, but that just means you pick and choose. As for distortion as it applies to ribbons, RAAL has...

    Attempts at Circular AMTs or Ribbons?

    The Emit was actually a planar device (Electro Magnetic Induction Tweeter) It didn't have a transformer. It might be very difficult to suspend a disc in a magnetic field.

    What is the worst speaker you've ever heard?

    Now really. The tweeter kind of sucked, but overall it was a better speaker than the BS22 that garnered so much praise. What was your major gripe about the 21?

    BMR Tower vs Revel F328Be Compared

    Hmmmm--don't know why that would be unless it's strictly a matter of sensitivity.

    KEF R3 vs. Philharmonic BMR Grudge Rematch to the Probably not Death Thread

    I checked the voting machines and could find no evidence of foreign tampering. As for level matching, there were dress rehearsals where the speakers were measured using pink noise (I think) and volume settings prescribed. I didn't hear any complaints about differing volume levels.

    KEF R3 vs. Philharmonic BMR Grudge Rematch to the Probably not Death Thread

    I can't help getting a chuckle out of some of you guys. Here you are dismissing the results of a major listening session without even knowing the pattern of results. No one is claiming it was perfect science. It never would have happened if that were the requirement. But I think most people...

    KEF R3 vs. Philharmonic BMR Grudge Rematch to the Probably not Death Thread

    No. What use are they? Way better than no results. And the vast majority of people there had never heard of Philharmonic Audio, so I really don't think the BMR's were advantaged.
