I don't know if this is the right section to post this little project of mine that ended this weekend. Basically, since I was 16 (I am now 48), I have always designed enclosures that had little footprint to the eye (I like them slender, short but deep - no nasty comment here). Meaning even a big volume enclosure had to be pleasing and not massive (yeah, honestly, I have always fiercely hated JBL's big boxes). Another fetish I had for the past 3 decades that I only applied on this enclosure is the "forward cabin". I have no idea from where it comes. Maybe something I have seen in the 1960s or 70s, but no clear memory of it.
So, here it is. A pair of 15" subs using JBL's 2235h. The enclosure is 16" wide, 29-1/2" tall with the casters, and 30-1/2" deep (it could be 50" deep, you wouldn't see it from the front. Volume is 4.5cft and the port is tuned to 30Hz.
The front extension is fully detachable (soft mounted with a foam gasket all around), while the main body is made from highly braced 1" MDF and curved laminated layers of 1/4" Massonite sheets. With tangerine orange stained birch venner. The interior is lined with 1.5" thick medium density grey foam. That thing weights 95lbs without the driver.
Better picture coming later.
