Subwoofer damping
Shadorne, my understanding is that a variovent is used when a sealed box of the size you need to use would result in too high a Qtc with a particular woofer (say, one with a high Qts). Some of the backwave's pressure, but not all of it, passes thr... 
Subwoofer damping
I remember Madisound carrying a very expensive Scan-Speaker woofer with a short coil/long gap geometry. I recall a peak-to-peak x-max of about 10 mm, or 5 mm one-way. I think this was a 12" woofer, but maybe yours is a larger version using the sam... 
Subwoofer damping
Forty cubic feet? Wow.Without knowing the parameters of your woofers, I'll just toss out the possibility that your box is too big. Can you tell us what the woofers are, and perhaps even what the port tuning is (or what the port dimensions are)?If ... 
I need some speaker help
I suggest high efficiency speakers with prosound drivers.You might contact Johnk, as he can probably build you exactly what you need. Other alternatives include the JBL model 4430 or 4435 studio monitors, or Altec Model 19, or Klipsch Heritage ser... 
Preamps with two pairs of balanced outs?
Atma-Sphere preamps can be fitted with a second pair of balanced outputs as a factory-installed option. I've had it done a couple of times.Dukedealer/manufacturer 
Change to Horns or stay Dynamic
Unsound, many horns do sound quite nasty. I have yet to hear a prosound hornspeaker that doesn't, especially at high volume levels.Two potential sources of nastiness are frequency response problems and diffraction. Horns all need some sort of equa... 
Change to Horns or stay Dynamic
Dgad,Thanks for asking for clarification - it sounds like I was giving an incorrect impression. Horns don't ordinarily give a more diffuse reverberant field than direct-radiator dynamic speakers. If anything, their typically narrower pattern resul... 
Change to Horns or stay Dynamic
Thanks for the mention Manga, and the clarification, Kana813. The ones that got the award are indeed bipolar, kinda like their designer....The subject of fullrange horns came up. Well, the Edgarhorn (with Seismic sub) and Classic Audio Reproductio... 
speakers for classical music
At the risk of redundancy, let me suggest taking a look at the paper Atma-Sphere linked to:http://www.atma-sphere.com/papers/paradigm_paper2.htmlBriefly, different amplifier types behave differently when they see a non-resistive loudspeaker load. ... 
speakers for classical music
I second Atma-Sphere's endorsement of Classic Audio Reproductions speakers. Tonal balance is excellent, as is inner detail, and they seem to have no dynamic limitations. They convey the emotion of the music extremely well, presumably by preserving... 
Something missing?
Shadorne, that was a clever but(t) cheeky response...;o)Duke 
Something missing?
Note that the hornspeakers Ditusa recommends use a fairly wide-pattern constant-directivity horn; these are imho a cut and a half above your average hornspeakers, and two cuts above your average prosound hornspeakers.The JBL 4430 and 4435 studio m... 
Mbl Magic?
Jtwrace, you know me all too well. Yup I like the SoundLabs a lot. My bipolars actually copy the radiation pattern of the A-1 over much of the spectrum, at least in the horizontal plane: 90 degrees, front and back.Assuming the upper end of our hyp... 
Mbl Magic?
I think the richness and liveliness you hear from a well set-up pair of MBLs is due in large measure to the unusually well-energized, spectrally correct reverberant field they generate. In this area, the MBLs replicate the soundfield characteristi... 
Emerald Physics CS-2, Opinions Please
My own experience with Robert Greene is that he doesn't join this or that product's "fan club"; he maintains an objective position. For example, he really likes the performance of the Gradient 1.3 and the Harbeth monitor 40, but is also well aware...
