    A force canceling subwoofer for implementing DBA's ( and Trinnov variant) around the periphery of a videowall based on the Purifi PTT10.0X04-NAB-01.

    Oh I considered it alright, what a great invention, but not appropriate for this Project. Marke Seaton was pretty convincing that his low profile 21" 7 of the would work in this room in a cylindrical waveforming application, you can't beat the price for the performance there. In the...

    All I can say is that the second in command at Trinnov which is the waveforming expert said that force cancelling prevents rattling of the walls krix showed this with a dual opposed facing each other venting through a slot, the founder of Speakercraft and part owner of Origin said sheetrock...

    A force canceling subwoofer for implementing DBA's ( and Trinnov variant) around the periphery of a videowall based on the Purifi PTT10.0X04-NAB-01.

    Both points are valid. Given that Perlisten is releasing a force-canceling subwoofer, I've halted my own development. A single center channel placed below a scope screen at sofa height performs superbly, as I was able to test at home after installing my first videowall scope screen. The REVOX...

    What makes The Beatles music still beautifull today

    Mono? I definitely was born one century to soon. I don't think very highly of this Liverpool music compared to its contemporary Canterbury music, one is a panacea for the masses with simplistic tunes, the other mini masterpieces of musicianship.

    Got my little hands on the Purifi 10"s

    Ive spoken to 2 subwoofer array manufacturers they keep each cavity sealed. Besides 2 woofers in parallel and 2 serial will have slight variances.

    Got my little hands on the Purifi 10"s

    i want to have 4 independent 15 gallon backspaces. Yes the new supports are arched contouring the speaker but with open space to preserve cavity volume.

    Better? Thanks to all that helped saved the project.

    I will see what can be done on both sides of the speakers.

    But it is trapezoidal bracing which has to have a positive effect.

    Got my little hands on the Purifi 10"s

    That would change the 15 gallon back box specified by the manufacturer also that would delay the project, there will be fluff attached to the perimeter to lesten resonances, thanks for the feedback.

    quick and dirty Elipson Planet measurements

    Thanks for the link. My speaker enclosure is the final one for me. I will continue to upgrade only the drivers, which are being developed for a second model. As for the enclosure, it's a keeper for my 7.0.4.

    quick and dirty Elipson Planet measurements

    A direct comparison may be warranted. For example, in 1956, RCA conducted extensive research on various cabinet shapes for what was then considered a single full-range driver. Surprisingly, the cabinet shape that yielded the greatest response curve, with all other factors being equal, was the...
