For pure dynamic range I have a copy of the Mussorgsky" Pictures At An Exhibition" transcribed for organ. And, since it gets into the 20's and up over the top, it really rings out a system.

HA!, I heard Hugh live last summer in The Concertgebouw here in Amsterdam. He tore the place down! What a performer!

Just to be clear: A single 8cm driver like the Alpair 7.3 will choke on sustained reference level playback. No argument there. But the question was: Can it handle the short powerful bursts of an orchestra up to 95db? To me it's clear that yes, it can handle that just fine in a FAST setup.

Ah - the Great Gate of Kiev - maybe a pair of servo 15's isn't only just for "Transformers"


I remember reading a quote somewhere (talking about Night on Bald Mountain) that "Mussorgsky invented heavy metal"

who else recalls Disney's Fantasia in Cinemascope & stereo ( was it 3 channel? ) as a kid in the late 50s - talk about foreshadowing of the psychedelic 60s

OK. A7.3 and two RS225-4's it is.

Obviously, one 8" would be enough, but I want two for the transient response. It is my theory that the larger the Sd and therefore smaller excursion, the sharper the leading edge of the sound wave. IMO this is what produces "slam". I cannot understand a 4-6" "subwoofer" with huge Xmax. The leading edge of the sound wave has to be mushy. Again, this based on my experiments with am 18" H-frame. At 100dB and 30Hz, I had to put my finger on the cone to detect come motion.

In my opinion this nails the two drivers. Head to head, I would pick the 10 if having to use a single driver, but with support, the 7.3 is the choice. I have got two 12" peeless coming as well as two CA 22RNX. Eventually they will be employed. IT will be interesting to see the difference in thet 8'' Seas vs the 12" Peerless, as they both have the smae linear excursion. Should give an very specific look into overall driver surface area and how it affects the sound delivered. EVen got measurement equipment now, to make it official

Some of us attended a St. Louis Symphony concert recently. The program included some selections from Dvorak Slavonic Dances, Rhapsody in Blue, a dance suite from Bernstein (Leonard, not Elmer), Ravel's La Valse and some other material. Not only were there very wide dynamics in these performances, but the orchestra played really loud. Not The Who loud, but we were all surprised. And we were sitting a few rows from the top of Powell Hall (best seats for listening). We didn't measure SPLs, but they were well above our ability to talk to each other.

I say this to suggest that very few, if any, speakers (even large mega-bucks multi-driver systems) will actually reproduce the full dynamic range of an orchestra playing full-tilt without the risk of relatively high distortion and / or damage to the driver(s). Even using semi near-field listening (my personal preference) much of the tonal purity, instrumental timbre and fine detail are lost when trying to reproduce large scale orchestral performances with loud dynamic peaks.

Wait a few minutes to reply so that I can put on my bullet-proof armor and get into the bomb shelter.

From what i understand, horns are the only thing that come come close to reproducing the dynamic range of an orchestra. Moving the amount of air that is need to reproduce just a single tuba is impossible...at least i think i have heard this stated. Could be wrong. I guess it is relative to the volume at which the music is played. I like it loud personally.

I think the JBL Everest D66000 played large orchestras very well... If I get the opportunity I will try some MBL 101 Extremes and Focal Scala Grand Utopia as well.

By the way, played some music today on my EL70eN's. Played way louder than i usually do and heck, they still sounded good. Seems like I've underestimated them. Although, I didn't play any dense music, just "simple" music.

Wont play them in my room, I'm not that rich :P But Audioconcept in Stockholm has them in their store in a slightly larger room.

Well, you might very well have heard that before because as I grow bolder I turn up the volume more and more
