    Posted this in the other thread but I didn't want it to get glossed over. Some info from Matthew Polk regarding the Bass Brace:

    Tony –

    The “Bass-Brace” was introduced as a recommended modification for the SRS 1.2 and was available free for the asking. The kit was composed of nothing more than a piece of all-thread, ?” I think, with a t-nut for the back of the cabinet and an selection of wall anchors. All late production SRS models came with the t-nut already installed in the back of the cabinet plugged with a bolt to seal the hole. (Note: when the all-thread is screwed into the cabinet it will often wind Dacron around it like cotton candy jamming in place and requiring removal of a driver to free-up.)



    The “Bass-Brace” did make a noticeable difference in bass performance. Slam and speed were noticeably improved. If you anchored to a masonry wall the difference was really quite dramatic, more than you’d get from improving your speaker cables and even better than spikes.



    However, the real reason for the Bass-Brace was not initially to improve performance. Around that time new industry safety guidelines were issued for loudspeakers which included a “tip test”. The tip test specified that with the speaker placed on an inclined plane at 10 deg. (as best I recall) it would not tip over in any orientation. Needless to say, the SRS products did not pass. That was a real problem and with an inventory of product already in the warehouse we needed a solution. The solution was the Bass-Brace which when installed prevents the speaker from tipping over. But, when trying it out we realized it also made a significant performance improvement. So, it became both a performance modification and a safety feature. However, it was very difficult to install and I doubt many SRS owners ever enjoyed the benefits. Over Amy’s objections I did install mine and anchored them to an 18” thick brick and masonry wall. It was very impressive.



    Hope that helps

    Cheers. :cool:

    When I bought my SDA 2B Studios back in 1988, the salesman gave me a pamphlet that detailed how the salespeople were supposed to demonstrate the SDA's. A lot of it was positioning of the speakers and is covered under the owner's manual. It also included 3 pages of songs to demonstrate the abilities of the SDA's. The guy said they normally didn't give out this pamphlet. I'll send it to you tonight/tomorrow and you can look it over and see if you want to post it under other information.

    Trey, can you add the "bass brace" mod that Raife did for his 1.2TL's and/or SRS's please? I didn't see it on your page, and others may like to read up on how Raife did it. Thanks Trey.
