speakers for a large room
I have a similar set up as preslisa64. My room is 25x45. I have a pair of Martin Logan Renaissance 15A and a pair of Martin Logan Balanced Force 212's as subs. I use McIntosh 1.2 kwh mono's and each one delivers 1200 watts. I have no problem filling every crevice in the room. I listen to just about everything but particularly enjoy jazz (Myles Davis), acoustic and classical. They deliver a great soundstage even at the lower volume levels. Ironically, my wife loves the aesthetics and the fact that you can see through them despite being large. Depending on how far you place these from the wall you get sound from the front and rear of the panels. Good Luck topjetboy!! |
@Duke I never had the maggies 2 feet away. I tried it today but really did not like it. As it is now, they are back to 5 feet away from the back and 2 ft away from the side. When I cross them to 45 degrees, the 'sweet spot' is broader but the image is blurred. I prefer the proper positioning for now, about 15 degrees toe in so that each panel faces my head. I do not understand how to measure the effects of reflections except for trial and error. So when you talk about reflections from the back wall, this is what I perceive as essential to the imaging. As a quick test, the image stays coherent even as I walk close to the imaginary line connecting the speakers and even walk past it towards the back wall. This tells me that I am hearing the reflections because the speakers are actually behind my head in this position. This 'walk close' test is how I 'measure' the reflection strength and direction. In terms of getting rid of the wall coverings, I never really tried that. I could just gather up the curtains with a tie to expose the wall and windows. Are you using dipoles (electrostatic, maggie, etc)? |

Well I admire your quest for knowledge in trying 2 feet! Yup, it sucks. Those additional 3 feet (to bring them out to 5 feet) make a huge improvement, because of the additional time delay they impose on the arrival of the backwave. " When I cross them to 45 degrees, the ’sweet spot’ is broader but the image is blurred." Maggies are NOT good candidates for the extreme toe-in that I suggested. Their radiation pattern is generally too wide, and the tonal balance changes at different horizontal angles due to the side-by-side driver configuration. " Are you using dipoles (electrostatic, maggie, etc)? " No, I’m using what might be called an "asymmetric bi-directional" configuration. The first-arrival sound comes from a fairly directional front-firing array, then the reverberant field is augmented by an up-and-back firing array, whose output bounces off at least one wall and then off the ceiling before arriving at the listening area. This long two-bounce path mimics the path length of a dipole speaker pulled at least 5 feet out into the room, but without requiring that much distance. The SPL and spectral balance of the up-and-back firing array is user-adjustable, for adaptation to different room acoustic situations. The Part-Time Audiophile took some good photos at a show last summer. Note the aggressive toe-in, and the up-and-back firing coaxial speaker installed in the speaker stand: https://parttimeaudiophile.com/2019/06/17/new-gear-from-audiokinesis-and-resonessence-labs-t-h-e-sho...
