    You are a patient man... I really hope you find a notable improvement from all that dampening. I'd have lost my mind by now!

    IMHO he's been brought under the mods microscope by another member.:( and stepped over the line one to many times. Bummer, he's is one of the most helpful, generous, contributing members we have.

    Okay,, but can you point me to where he went over the line please. He has some very good threads at the moment and I would hate to see members deprived of his SDA upgrades.

    I don't know where he stepped over. It's just a short, temporary ban so he'll be back soon.

    Me too! Those mounting rings he made for the drivers and PRs is an awesome idea. My PRs screw holes are all stripped out and the MW screw mounts are pushed towards the inside. Those rings would sure be a God send plus they make the Mortite fit tighter.

    Well You guys have seen my rings in the other thread I am using for the drivers and passives.

    Larry, those rings are pure genious. I want a set if you decide to start selling them!

    So here are a couple more. as you can see I have put in the BlackHole and Sonic Barrier on the walls. I have also added some extra cross bracing to the side walls. I used 1 3/4 round Oak dowels, I put 3 in each cabnet.

    I have some concern about the extra sound coating and bracing because they may actually work against the acoustic properties of the cabinet. Did you discuss any of this with Polk's engineering department?

    I say this because the SDA 1.2 and SDA 1.2TL cabinets were redesigned to drastically reduce resonance though the use of a "monocoque" structure wherein the rigidity is derived from the external casing rather than internal bracing. [Reference: Monocoque-Wikipedia]

    Adding internal bracing or adding bracing in a less than ideal location might actually reduce the resonance reduction properties of the monocoque cabinet sturcture.

    It appears that the thick, soft sound coating materials (Black Hole and Sonic Barrier), which are much denser than polyfil, are changing the interior dimensions of the cabinet and providing a large absorptive surface for air. Therefore, rather than air pressure being channeled through smooth, hard interior walls and efficiently transferred to the "fluid coupled" passive radiator, some of that air pressure is now going to be transferred to the thick padding. I would think the result of this would be diminished bass impact and speed.

    The textured surface of the sound coatings may also induce more air turbulence inside the cabinet, which would affect the response of the drivers and the passive radiator.

    Raife, I agree with your thoughts about the sound coating and extra bracing.

    Sonic Barrier really doesn't displace much. To get an idea of how much air it displaces, if you step on it, most of it's depth disappears.

    Sonic Barrier and Black Hole don't do much for cabinet resonance as they do for standing waves. Poly fill is only good for high frequencies. SB and BH are much more effective for mid and low frequencies, preventing them from reflecting off the back wall and through the cone again(distortion). In turn, you should experience more coherency, better defined images and possibly a larger soundstage.

    I would think with it's density most effectivness is in the mids.As long as there is no hi density stuffing restricting airflow from the backwave of the woofers to the PR,then it's operastion / tuning should be unaffected.

    I am pretty sure that is why in the end you have to listen to things, not sure, but pretty sure, that you have to listen to be sure that is.

    we know that fluid always seeks the path of least resistance

    so what??? he said dirty light bulb too someone....shame

    LOL! That is exactly what he told me today on the telephone. He's definitely taking it in stride.

    What kind of speaker cable are you going with for the innerconnect? Wonder if matching speaker cable and innerconect would be the best bet.
