  • Overnight Sensation vs. Swope: Reduce BSC for on-wall mounting?

    First post here! I am looking for the right high-value design to build for a small bedroom wall-mount stereo system. No subs.

    Forgive me if this has been covered before; I tried to search through the forums and Paul's site before posting.

    The Overnight Sensation TM, Overnight Sensation MTM, and Swope TM are all on my short list. But I can't find good information on how much BSC is designed in the crossovers for those designs. Other than port location for ported designs, are they suitable for wall-mount without modification? If not, what components should be tweaked?

    Related question, how shallow can I make the enclosures on these? Let's assume I keep the volume the same by making up the difference in height, and I find room for the port (slot or out the top/side/whatever)... Then how shallow before it becomes a problem? In a 6" deep enclosure, you could still fit thick foam behind the magnet of the woofer in both designs.

    Final question...are there other obvious candidates that should be on my short list?

    Thanks!

    Cameron:
    Mine are mounted in a 5.5" deep enclosure and the interior walls were lined with cheap "rubber" backed area rugs ( from "Dollar" stores ) and the polyester pillow fill ( same source ) was used inside.

      Nice! Did you make any changes to the crossover to reduce BSC?

        Just to be clear - I was offering a suggestion for an alternative to thick foam in a shallow cab.
        This is NOT the Overnight Sensation design, by rather an in-wall MTM of my own.
        No BSC ( not required ) and it uses active crossovers.

          Paul, any chance you might notice my thread and chime in straight from the resident authority on these designs?

            I just replied to your email. But basically, the Overnight Sensation TM and MTM have been wall mounted countless times, and seem to fare just fine. No changes are needed for this config.

            Now, if the speakers were mounted INTO the wall, then changes would be necessary.
            Isn't it about time we started answering rhetorical questions?

                I was looking to do something similar here but actually build a shallow box, front port it and mount it into the wall. Paul, would you consider modifying the crossover to allow for this?

                best regards,

                Pete
