BDA front wall vibration
Posts: 4

I will being your BDA, perforated absorbtion units but need clarification concerning the front wall assembly. You state in videos the importance of the front wall being to vibrate in sympathy with the next wall and specifically state the dado be well fitted so the wall can vibrate as you designed. sam smalls video shows him applying caulk to the perforated wall seams, locking them to the side walls. am i looking to deep in deciding that the dado should be somewhat tight or is his caulking necessary to anchor the wall to the side wall so that the baffle can vibrate as you designed?
One more question please; The longer the baffle, the easier it will vibrate versus a shorter length. How do you reconcile this with differences in height of the units you sell at 60' high versus the diy at 48' high?
glad to hear youre doing better dennis. Thank you for all your efforts.
