I keep trying to come up with a design that can approach the sound of the 1.6 cu ft 12" woofer loaded cabinets with a MT (separate 5" mid with 1" tweeter) cabinet sitting on top and crossed at around 150 ~ 300 Hz - only in a much smaller cabinet/footprint.
So far all I can come up with is to emulate the Troels and his Bass Module using an 8 " down firing subwoofer driver with face tilted upwards (30*) and out of a rectangular opening in the lower front of the cabinet (~ 1 cu ft or less) with the Mid installed just above that woofer opening and the tweeter mounted above the mid.
This alignment is in order to maintain the SHORTEST Height of the overall enclosure. I'd rather it be deeper (depth) than taller or wider but keep it under 10" wide, overall and no more than 14" tall.
If the woofer is vented then the port can go on either the front or back - I am looking for detail and note-changes not just one-note thump.
If the Woofer is mounted on the bottom at 60*-ish from the MT - how much difference will it make (phase-wise) if crossed at 150 HZ using 2nd order/12db X-over?
The Troels say that below 150 Hz you need to move air fast with a lot of surface area to make good sounding low-end and from my experience he is right as rain.
86 db sensitivity isn't going to cut it in an 8" woofer . . . or will it?
