new speakers/used/demo- 4K- 6K

CALLING DUKE< PLEASE COME TO THE INFORMATION BOOTH
as i've nosing around, i read w/ great interest the knowledgible and honest explanations of a member on audioassylum explaning planar speakers[maggies and sound labs] to the members on the assylum. this is our own audiokinesis a/k/a DUKE.
i have zero exp w/ planars--would a maggie 3.6 or 20; or a soundlabs M-2/M-3 or A-2/A-3 fit my criteria including rockn' roll, duke ellington & mahler @110dbs in my large room. i know that the string quartets would be spooky.
thanks for any info that you might provide---BOB

Bob -

First of all, thanks for your kind words! Yes you've uncovered my alias - I'm "AudioKinesis" here, and "Duke" at the Asylum. You see, at the Asylum, industry members aren't supposed to use the name of their business in their moniker, which is fine with me.

I'm afraid 110 dB is beyond the capability of most full-range planars, and at the edge of the envelope for the few that might be able to do it. It would require far more powerful amplification than even what you have.

It's a tradeoff: we full-range planar lovers trade off levels over 100 dB for being able to do lesser volume levels with superb clarity. I do have a couple of Sound Lab customers who approach 110 dB peaks with their systems, but they have spent much more than $4K - $6k.

If we throw that 110 dB in a large room requirement into the mix, our choices narrow considerably. I would estimate you'd need conventional (point-source) speakers of 96 dB efficiency to give you a clean 110 dB of music at the listening position. Here's how I figure it: Starting out with 96 dB for 1 watt input, halfway across your room a single speaker would be doing about 87 dB. Add the second speaker, and we're back to 93 dB. Add 200 watts to that, and we're at 116 dB (ignoring dynamic compression, which would be minimal in a speaker of this efficiency). We'd want 6 dB of headroom to be able to handle instantaneous peaks, so that brings our clean music SPL down to 110 dB.

Now, if you're only talking about 110 dB maximum instantaneous peak capability, and maximum average levels of more like 104 dB, then 90 dB efficient speakers would theoretically suffice.

I'm sorry to muddy the waters, but it's all about tradeoffs, and that 110 dB requirement changes the picture significantly. And, do you mean 110 dB maximum peaks, or 110 dB sustained music?

my pass aleph 1.2 will put out a clean 105db on the rat shack meter thru b&w 802 serIII which aren't that efficient.
i guess i'm leaning more towards peaks, but it's not comfortable to listen to the hi db for long time periods--more than ten minutes or much, much less time.
duke, you are far more knowledgable than I. its great to feel like the stones, tito puente or the radiators are in my home!! i can't get a feel of the compromises that you are suggesting w/ the sound labs and the big maggies. if i cannot ressurect ray brown by feeling his bass in my gut, it's not life-like jazz. do the piega 8 or 10 involve the same compromise in sound level and dynamics?
