  • They were free!

    What should I do with them?
    These were completely assembled and on display in Deetes Sound Room in Carmichael the last time I was there. When I went by there today, all that was left were the enclosures.
    The enclosures originally had a 12 inch full range driver installed. The enclosure construction is pretty good, but this design really sounds like cr*p. Yes Mr. MSaturn, these really did sound bad.
    The distributor of this pair took out the 12 inchers, took off the grilles and removed the input cups. He left the enclosures and Deetes gave them to me.
    I could turn them into subwoofers.

    You could also make a 'mini-3-way on a plate', and install it.

      I was actually thinking of cutting off the entire front baffle!
      Then gluing on a new one.
      Or if I could find an inexpensive pair of 12 inch woofers.
      Quick and easy subwoofers!

        Perfect candidates for a pair of 12" Tannoys.

          Install some internal bracing. Remove the ports and everyrthing else that projects above the baffle surface. Scuff the finish off the baffle. Laminate a new baffle onto the face of the existing baffle. Mill the new baffle for new drivers. Seal, fill, level, smooth, prime, and paint the new baffle. etc...

            2.66 cubic feet internal volume.

            But I can't afford Tannoys, maybe something else.

                That's a little small for a pair of Tannoy's anyway...you're off the hook.

                  They're well-suited for the Pioneer BOFU driver, you'll just have to add a new baffle piece to mount the driver over the existing hole. A little extra bracing and you'll be golden. You can go whole-hog and get a pair of ND20FB-4 supertweeters and mod the drivers up (I have them installed ina a coaxial arrangement with 2.2uF- they're a superb match) and have a REALLY nice pair of speakers for <$100 and a few hour's work.

                    the 8 inch vifa coaxial would work
                    cut a pair of mdf rings.
                    use the bi amp plates.

                    I ran them sealed in this build. but you could port.

                    also some else sells a working
                    bi amp plate a little bit lower cost.

                      wakka wakka bad sounding full rangers? what's new? :D

                      but hey, if you have free enclosures, even I'd be willing to give them a listen/ try. too bad I don't get free boxes :E

                      would make for some easy stereo subs with some bracing. just take off the front baffle and go to town with some shelving and you've got a serious 12" sub box! and stereo if you want!
                      I am trolling you.

                        Hey, I don't need to cut off the fronts to make them into subwoofer enclosures.
                        You can cross brace them inside with pieces of 2 x 4 or other lumber.

                          How about some of those AR12's from Jack Hidley? He still has some NHT drivers and stuff to clear out:

                          Jack is also selling some Peerless and TC Sounds 10" and 12" subwoofers. You have to click on the spreadsheet at the top of the page to see what he has as these are not pictured on his main page. Here is the link to the spreadsheet:
                          http://home.comcast.net/~jhidley/NHT_Drivers-2.xls
                          Scroll down a bit to see the TC Sounds and Peerless offerings. Some of those Peerless drivers can work well in a small box.

                              Just the notion of a 12" full-range speaker makes me think of listening to music through a guitar amp. Eeugh. In order to have low enough mass to reproduce the treble range, they've got to have extremely thin cones. Which is great, if you like breakup with your highs.

                              For me, the ideal size for a full-range driver is between 4" and 6".
