[QUOTE="Art Welter, post: 115640, member: 52"] Re: tall skinny speakers You wrote "it does have the pattern of a horn that is around 27' deep", and Tom Danley wrote a similar thing on the facebook page (only he said 20' deep and 5' tall) and the "preliminary" specifications sheet claim it "is actually a large horn with an effective path length of over 25’!" The problem with those statements is the SBH10 does not have the pattern control of a large horn of those dimensions, which would have -6 dB pattern control of around 10 degree vertical down to around 225 Hz. The polar graphs of the SBH10 show by 800 Hz (the very upper range of speech fundamental frequencies) it is 30 degree vertical, 400 Hz around 45 degrees, and nearly 90 degrees at 250 Hz. Although the polars look relatively smooth (but who knows what they look like in any frequency range where the SBH10 actually exhibits a pattern control of 10 degrees) they most certainly do not look like those of a large horn with a depth of over 20 feet. The response does look like classic "pattern flip", but one would not expect that from a "horn" that is 20 to 27 foot long with a 5' tall mouth. For over half the audio spectrum the SBH10 does not conform to the rated specification, and the so-called horn gives no low frequency gain whatsoever over what would be expected from eight 5" drivers in a 60" tall line.
