I find the prototype better looking than the "final" products .. They look too much like giant butterflies > Now are these 15 inches drivers or 15 inches compression drivers? ... They look like regular woofers to me
Hi Frantz,
I am not quite sure about the 15" drivers, you may be quite correct and I think that I may be mistaken; I may have misread what Larry Borden of Stereo Times had reported. This is what Larry Borden of Stereo Times reported about the OMA New Yorker speakers; Larry has the 2nd pair of speakers that look like mine:
I am a fan of high-efficiency speakers, both for their SET amp-friendliness, and for their incredible dynamics. Whereas many such speakers use horn-loaded compression drivers for the highs and mids, bass frequencies pose a considerable problem. Low frequencies require very large horns, which are impractical in most settings. Many designers therefore opt for “traditional” woofers, but this brings its own set of problems, namely one of integration. The new OMA New Yorker speaker is a two way design, encompassing twin 15" neodymium extreme high efficiency woofers with a conical horn and neodymium compression driver. The horn is cast in aluminum by OMA at a foundry in Pennsylvania, where the speaker is built by hand using select hardwoods such as Pennsylvania walnut, cherry and ash. The main body of the speaker enclosure is constructed from 25mm Baltic Birch ply, veneered and finished by hand with Tung oil. The unique twin woofer configuration affords a kind of front horn loading, increasing bass efficiency and minimizing room interactions to a great degree. An optional solid hardwood set of baffles or "wings" further increases this effect. The New Yorker's unique design allows perfect time alignment of all drivers.
Overall efficiency is 105db/1w/1m, frequency response -3db 30hz to 20khz.
