28"W x 12"H x 18"D HDF with LE10A, PR10, 2405H, 2426J/2312/L94, 3110 & 3106. I tried a 2441/HL89 and 2410/2312/l94. I had a Klipsch Academy for a horn loaded center but saw this post and decided to go JBL to match my S20R's upgraded with 2450J/2380's.
Nice that looks like a real kick ass center channel. How do you like it? Do you run it fullrange?

Here are two more updates. I bought the fiberglas horn from a shop in Montreal and mated it to a 2450j and now have a 2397 on it. So far the 2397 sounds the best to my ear. I have no sound test equipment so I listen to one then change to another. Notice that I had to move the 077's when I exchanged the LE85/HL91's for 2450J/2380A's on my homemade S20R's built in 1974.
Ah.......That spk is in the way of the TV sir! The Smith version looks quite cool. How do you keep it from falling over the back side? I know that the 2450 is some what light, but not that much?
I have some 2397's too but alas I have too many speakers in my living room already.
It's a 4:3 screen. If you watch in 16:9 and place the image at the top of the screen, the speaker should not be in the way.
At 78" dia., according to Stewart, I have the second smallest 4:3 Firehawk they ever made (at least at the time). Our 16:9 viewing is done at the bottom of the screen so you don't have to look "up" nearly as much. The smallest 4:3 Firehawk was 72" and I saw it being used in a booth at the CES in Las Vegas.
I put a thumbs up in there??
Nice room there, wish I had so much space. I need to move.
I don't know anything about the Firehawk, is that what his is too? I'm still in ctr mode with one of the last great ctr rear projection sets from Mitsubishi. It's very hard to beat the black levels of a good ctr. I just wish that when we got it we had the room for a 73 but had to settle for a 55.
I didn't know an image could be moved up and down like that except for the usual adjustments.
At least I can put a speaker on top of mine.
He appears to have either a Greyhawk or Firehawk. Both are grey screens for improved contrast and for viewing in less than black conditions. I think the greyhawk has a "gain" of 0.8 and the Firehawk has a gain of 1.3.
If the projector has a 4:3 native resolution, it can typicaly display the 16:9 at the top, middle, or bottom of the screen and is selectable. It's just a matter of whch pixels are switched on or off. Also they do upside down and backward for various mounting options.
Mine is LCOS with a 4:3 native resolution of 1,365 x 1,024. When I shoot HD format the resolution is 1,365 x 768. The standard is only 1,280 x 720, so even in HD format, my resolution is 13.75% higher than the HD standard.
I guess I misunderstood. Those are screens and you use a projector? I've been looking over Stewart's web site.
I bought the Stewart Grayhawk (SNDQ90V) on Ebay for less than half retail price in 2003. I'm on my third ceiling mounted TV projector (Panasonic PT-AE-4000U-greatest for the price). I tried to buy some black Velux applique to convert the 4x3 to 16x9 from Stewart but they told me that they don't recommend installing it across the bottom.
The HDF center box is 18" deep so there is plenty of room for the 2450J.
HD has a few "Standards". The top resolution is actually 1920X1080, called 1080I. (I for interlace.) A lot of projectors now do 1080P (P for progressive, i.e. no interlace) or higher, either by up-conversion or de-interlacing.
For film transfers 1080P is popular. I'm not going into all the different frame rates...
1280X720 is a "Native" progressive format, known as 720P.

The "High Definition Standard" for broadcast television is 720P or 1080I. I, as many people, find that 1,280 x 720P from my Motorola cable box (upconverted to 1,365 x 768P by the projector) looks better, especially on action shots, than the 1,920 x 1080i, at least on my projector. While 1080P is now available on such things as BluRay or though deinterlacing/upconversion, the brodacast standards remain as they are.
