I am planning on purchasing as pair of speakers to go with my Muse Model 18 subwoofer. I have to keep it under $2000.00. I have Adcom GFA565 mono amplifiers and a Adcom Model 565 preamp. I will be using a Thorens turntable, Model TD160 as my source.
Class A is a type of amplifier, not a speaker.
Speakers are not rated that way, only amplifiers.
Stereophile is a magazine and they have a list of what is called "recommended components" divided into Class A, B, C, and D, with categories for speakers, subwoofers, and electronics.
Class A is predominantly over $5k bookshelf speakers $10k floorstanders; high end Dynaudios, Revels, etc, although a few lower priced speakers like the Usher Be-718 ($2795) managed to sneak in.
Class B are midrange speakers, usually under $10k floorstanders, under $4k and under bookshelf speakers, although there are some expensive designs that don't make the cut.
Class C are typically high performi♦ng budget ($2k and under) speakers.
i thought most A. subwoofers are class D anyway
I believe most subs are Class A/B still. BASH is one of the popular cheap class D amps they use in a lot of HT subs these days, but it's plagued with reliability and sound quality issues, which is why you don't really see it in anything but extreme budget subs.
How is that funny? While it's no doubt overpriced, but it's one of the better subs out there. It's basically an F113 with 3db more output. The JL subs do not produce a lot of SPL (It's a 220lb sub in a small sealed box) but their extension is among the best. >90db output at 12.5 Hz is incredible. Car audio and home theater are much different markets but JL got the gist right when the transitioned to HT, although they are charging you $6,000 per sub. Similar performance can be achieved with a $1500 sub like the SVS 13.
im guessing klipsch, bowers and wilkins and some others, are made for HT instead? right?
Klipsch subs are for pure SPLs. You can see here output falls dramatically below 50hz but it keeps up very high SPLs overall. The reason for this is Klipsch speakers have high sensitivity/output so they have to design their subwoofers in the same fashion to keep up with their mains. Klipsch works well to fill a large seating area on a budget but the overall sound quality is lacking due to lack of response above 13KHz (horns are very directional) and non-existant low bass.
At the price range you mention nothing will be competitive with the very expensive speakers that Stereophile magazine rates as "class A". However I would suggest you listen to the Revel F12 towers ($1500) or Revel M22 mini monitors ($2000). If you can stretch to $2500 the new Atlantic Technology AT-1 tower would be another great choice (works great with Adcom amps). These represent great bang for the buck.
