Does Wilson Sophia Sound good at low volumes?
Newton,The decline in LF hearing sensitivity as level is reduced is usually portrayed by a set of hearing sensitivity curves published by Fletcher and Munson, of Bell Labs IIRC. Preamps and receivers with a knob or switch labeled "loudness" usuall...

And so it goes. Enjoy your A-7s.db 
Projector
Just revisited this thread. Mitch, I stand by my 7/20 post. I suspect your judgement of a high quality picture differs from mine, but perhaps the OP would be satisfied with your picture, which I suspect I would judge washed out and lacking in deta... 
Projector
Mitch,You may have mislead OP with your bigger is better comment. It's not just a space consideration. It's the ability of a projector to throw an adequate picture on a large screen, an ability unlikely on a 150" screen for any projector even thou... 
It is all about the ‘Room’, thinks Toole.
Judging from many of the posts on Audiogon, Shadorne, I think it's mostly a hobby about fools' gold, mysticism for the gullible. Toole's advice pretty much comports with what I knew about psychoacoustics when I was active in the field, but it's no... 
"Best" multichannel universal player right now?
Of course, knee of the curve is a general term that refers to a break in a plotted function. In the case of a cost/value function, it's usually the point where cost rises faster than value, often much faster. I think the argument in these posts is... 
Altec Lansing A7's 50's model
Learsfool,I am one of those people who used an A7-500 and MC 60 in my home, when I was a graduate student and the A-7s were being surplused. As I previously noted, hard to beat for the horns in the triumphal march of Aida, but not my choice for a ... 
Altec Lansing A7's 50's model
Hey, Ginas, I'd take the comments of Spl and Learsfool with a grain of salt. Finesse and texture are not terms that come to mind as I recall the A7. One only has to consider their design aim and common application: Auditorium sound. You might like... 
Single vs Dual Subs
Bob Reynolds,I refer you to pages 2, 22, and 28 of the Harmon paper re a single sub in a corner location. Of course that may not be ideal for every room and equalization is usually desirable for LF.I use a Velodyne SMS-1 with an HGS-15 located so ... 
Single vs Dual Subs
Didn't this issue come up in a series of posts a short while ago? One of the posters cited the Harmon web site. Their expert advice based on psychoacoustic research differs from that given in these posts. Given that LF has little or no directional... 
What's the best Sony CD/SACD player?
Allen,My DVP-S9000ES had a bit of stridency. When it finally failed to play SACD discs reliably, I sent it to Sony Larado. According to their report, Sony overhauled it and brought it up to specs. Whatever they did, the stridency is gone and it is... 
Older Altec horn speakers
Altec's claim to fame was their VOT speaker systems, aimed at auditorium use. We had several such units in our psychoacoutics lab, and I had one at home for a time. IIRC, the HF sectorial horn came in 2 sizes with 2 different drivers, one for 500 ... 
1 Subwoofer or Are 2 Better??
I found the Harmon paper interesting, although I think there was little new that I didn't already know, but it is a reasoned explication. Bottom line is that one well placed sub, often corner placed, is usually all you need unless your room is ver... 
Velodyne's Dim View
My experience with Velodyne couldn't be better. I had a bit of a problem with my HGS-15, and dropped it off in Morgan Hill while attending the Monterey vintage car week. I talked and exchanged emails with folks at Velodyne, and they couldn't have ...
