  • My take on the BBC thin walled lossy speaker enclosure .

    The idea is to prevent each panel from transferring its resonance to the other panels.Each panel including top and bottom will be separated by 1mm washers.In theory this should reduce colourations.We will see.Ok so I am at the next step and I believe having an optimum size reflex box was not a good idea as the escaping pressure has reduced bass depth.Might have to place some wooden blocks inside to reduce the volume.The sound reminds me of listening to OB designs.

    Looks interesting: is that an SB16PFC woofer? If so, how do you like the sound?

      It is the SB 13pfc25-8 and I love it.It`s priced like Radio Shack but believes itself to be a Scan speak.

        No thanks, I'll take a thick, heavy, well braced enclosure.
