I recently acquired a 12" Pioneer full-range driver with horn tweeter in the middle (is this coaxial?). printed at the back is Pioneer PAX-30G, full-range, 8ohms, 20 watts, Made in Japan.
the cabinet is huge 26"x15.5"x12"(HxWxD), with non-removable grille, 3/4" plywood construction, and rectangular port in the bottom front. damping is minimal (a 15"x12") cottony substance stapled to the back plywood panel--colored yellow due to old age). The tweeter, BTW, has a level control or VR connected to the back plywood.
the sound is a bit muffled, if the cabinet is used, clear and sweet if listened to in the open; the bass is almost non-existent or so-so. (the back panel is screwed loosely in six places and bracing is at a minimum-- I'm probably listening to cabinet coloration much more than the driver).
i've searched the web but can't seem to get any info. not even from the single-driver website.
maybe you guys can help me out. is this a good candidate for OB?(reading through all your posts makes me want to try OB)
or, should i just reuse the cabinet, add bracing, cover up some holes (make it non-resonant) and tear off the grille? --it's stapled inside the cabinet
if i reuse the cabinet, should i use stands to bring it up to ear height? (the driver btw, is located at the upper third of the cabinet front; and mounted from the rear).
this is the nearest reference i could find http://www5b.biglobe.ne.jp/~tritium/pax20f.htm
the PAX-30G's horn does not extend to either side of the edge. and is protected by a grille in the middle. hope to post some pics.
tnx for your advise.
