The tri state area sales rep for Sim2 calls on me for James Loudspeakers and other products. Previous to Sim he was the rep for Runco for 8 years. If you like I could ask for his advice? Tom
Runco has trouble even providing parts for a 2 year old projector that they had 99% 0 build influence on from the get go. Very much a tweak shop that buys a whole lot of advertising and marketing and a 40 point markup for their dealers. They don't make anything its farmed out. Tom
JK you have a great system and room! I should have mentioned that there are other fill materials for stands. These other materials will be more reactive to vibrational energy than sand thou more dollars. Both steel shot and brass {not lead] will drain away more vibrational energy more quickly to ground than sand. For proper termination of the stand they would need to be grounded to the floor with some type of coupling points preferably also made of brass. These methods and materials would couple the speakers acoustic energy into the room more effortlessly and result in more open sound. Tom
The use of sand will decouple your speakers from their acoustic environment. Acoustic instruments played naturally in the great outdoors in the nearfield with no boundaries will sound nothing like what is being referred to you by others. There will be no dynamic coherence or scale. Tom
Jk I think of room acoustics as if they were areodynamic devices and how to improve the flow. Smooth the flow from the source not having to fix the flow down the trailing end. Redirect the energy at hand hoping not to kill the dynamics..All the while focusing the dynamics at the listener who more than likely paid for the hopefull outcome. Tom
Jk I found the digital eq of my room to be an overall negative investment. Its gone. Yea the bass went deeper and I was able to reduce a void that I had, but the bass had no musicality to it at all. One note at a time one after another, really dry, no harmonic flow.
Flow thats what I feel the angles improve. They improved the overall loading thru out the room. The prime spot for listening became broader and more defined. Bass loading improved at other positions as well. I found that loading the upper corners behind the speakers and redirecting that information towards the main listening position increased the midbass weight and impact{measured] and enhanced the stage stability. If I could eliminate all the 90 degree angles at the wall ceiling junction I would. Tom
Adding the 3 other soffit areas made the room symetrical..thats great to balance the pressure. What I found in my room that is 21w/27L/9 is that the soffit overhead that is symetrical in the room caused a dip in response of 5db between 50 and 80 hz at my listening postion. This was measured with an Audiocontrol RTA at the ceiling the chair and near the floor. When I put an angle of 32degrees across the full face of the sofitt most of the bass came back plus the image and focus improved as well. Since then I have incorporated similar angles in the room. One large enclosure is around my drop down theater screen. Looks like a spaceship there on the ceiling I think it looks pretty cool. Main thing though is that it too improves the punch and again stage and focus. I happy for you that your room and your system all came together. Tom
Jk did Rives advise you on the actual construction of the room from the outset? Did they offer any geometric advice from the start concerning sonic issues generated by 90 degree angles mostly those at the soffits? Tom
