Bob Posted February 17, 2022 Author Share Posted February 17, 2022 As an FYI, I was able to find the measured frequency response difference for the Stewart MicroPerf AT Screen that I have. Defining the Difference in Perforated Screens - Stewart (stewartfilmscreen.com) As you can see, the high frequency attenuation starts around 5K and above.

I'm going to look into what Anthem ARC can do for this case. Probably turn up the pot(s) also. Looking for other ideas as well. Link to comment Share on other sites More sharing options...
Holmz Posted February 18, 2022 Share Posted February 18, 2022 The new MiniDSP flex is a 2 channel (IN) to 4 channel (OUT), so one would need 2 for L/C/R. (As they are the ones behind the screens). I would assume that the anthem may be better, but some room correction speakers do nothing above ~500 Hz. The ~5dB in insertion lost can be absorption or reflection. Ideally one would hope for absorption, as reflections will have it rattling around behind the screen. Any loss in 2.0 quality from a DSP is probably going to end up as a gain in your situation… But it is uncertain. There are some PC Audio approaches, and if the screen and speakers were in, then one could likely take a CD track and apply the correct to boost the high freqs, and do a listening test against the raw CD. That would be a cheap way to dip a toe into the water. If it was a DSP, then I think you might want a 4(IN) to 4(OUT) to service those three channels. I just ordered an 8 channel DAC, (Octo DAC8), so it mostly a paper and google exercise for me at the moment. Hence these are opinions and ideas more than solid facts.

Thanks for the idea though. Link to comment Share on other sites More sharing options...

RV While all that is largely true, the OP seems like they are totally backed into the corner as the screen needs to be there to see the video. And it is good to hear enough of the content to understand the dialogue. Boosting the higher frequencies with a FIR based EQ, using some mix of minimum phase, and symmetric FIR would at least give the boost with destroying the phase and timing. (But that also assumes that the video side could offer a way to sync the lips.) Maybe many of those sound bars are uncomfortably bright, so as to make up for people using screens? (I dunno.) In a world of compromises, I am pretty sure I am better off using your speakers and some correction. At least after hearing a few of the HT speakers, I concluded that I was better off building upon the 2Cs. But then again, I am no expert. Link to comment Share on other sites More sharing options...
JonM Posted February 21, 2022 Share Posted February 21, 2022 I am coming in late responding, but I would suggest looking hard at 3 matching center channels, placed on stands (custom, see Core Audio Design for example) in front of the screen. I know a lot of theater folks like the hidden look, but I actually went the other way. I like seeing the gear. I used 3 Triad Platinum centers this way in front of my Stewart anamorphic screen. It would be great if you could squeeze Treos under the screen but it doesn’t look like you have vertical clearance for them. You can high-mount the centers just below the bottom of the screen. And, you get the freedom of moving them about to optimize the room. You can easily lay them out in an arc pattern like RV suggests. Link to comment Share on other sites More sharing options...

The 3A Sig behind the screen with the Treos outside is a good compromise. Gives me some freedom for 2 channel as well. 1 Link to comment Share on other sites More sharing options...
ctsooner Posted February 23, 2022 Share Posted February 23, 2022 Can’t wait to see what you come up with and how it sounds. Seems to be simple to try either way so that’s a positive. Link to comment Share on other sites More sharing options...
Brad O Posted February 24, 2022 Share Posted February 24, 2022 For 2-channel listening, the first row appears to be closer than an equilateral triangle. The second row is too far back to make that possible as well. 1 Link to comment Share on other sites More sharing options...

I understand what u guys are trying to do. I fully support it, but the train I got off on was the 2 channel. I remember being in Brooklyn at the premier Wilson dealer years ago. He has a system of all 5 channels of Watt Puppies (not sure which mark but it was one of the 200 or so marks they kept coming out with). It used the lexicon electronics I bet. It was all state of the art at the moment for multi channel. There isn’t a to. Of cohesion with those speakers anyways, but this was a trip. How could anyone listen to that for even 30 minutes? The owner of the store was so pissed at me for not liking what I heard. It was so out of phase. The bass was disjointed. since that day, I stood even trying multi channel. Some of my friends do it and love it, but each one of them has a dedicated audio room for the 2 channel set up. It’s never easy lol. i admire you guys who do the set ups. Would love to hear it someday Link to comment Share on other sites More sharing options...
