I didn't see the following ID Speaker brands in this list:
<2K
Pi Speakers
ARX Speakers
Soundfield Audio
>2K
Theorionspeakers.com
Gedlee
Vapor Sound
Audiokinesis
Seaton Sound
JTR Speakers
Grimm Audio
Selah Audio
Clearwave Speakers
And also, Magnepan's MMG I believe is an ID only speaker, even though they're fundamentally a B&M company. It should be worth noting since it's a very good option at ~600 dollars.
Also, I don't know why it was said that Funk Audio only makes subwoofers. One of the posters here on Audioholics was raving about their
8.2 MTM speakers with the dual 8 inch high efficiency faital woofers and larger format high efficiency planar tweeter. It also had the 7.1 two-way tower before:
Those discounts are already factored into an MSRP. I don't see it as a pro or a con.
Again, this isn't free, it's just already factored into the price, and very much brand specific. Aperion for example offers a hand rubbed piano gloss for much less than that.
They're not "feasable" to build B&M either, though. Those speakers are into the five digits.
Not sure how this is an "advantage". I've seen plenty of ID companies in Soundstage and Audioholics. SOme of those other ones give totally useless, smoothed graphs that don't tell you anything about the speaker. All that really leaves is stereophile, whose frequency response graphs are a bit of a gong show but their normalized polar response is useful.
