So in an ever on-going goal of efficiency in any and every way possible.. Ive taken a liking to a little woofer. The MCM 8"
to be exact. Anyone in HT will probably recognize it.
My goal was originally a decent system for 100 bucks. The woofer is ~40 shipped, and MDF is 30, but the amp will be a problem.
So can we get a full system for 100 bucks? No.. but expanding the budget to ~150 should get you an amp with a SSF and a sweet little woofer.
The enclosure Ive been working on..
34wide, 11.5 tall, 10.25 deep.
Is it a low end monster? No, but most people going for a single 8 and low budget wont be striving for teh l0ws. The idea is, when placed properly in a vehicle, the added loading and cabin gain should get you down to 35 or more with ease (thats the idea, anyway).
An off-axis firing enclosure may help as well, but would require a larger mouth. But when placed close to a trunk wall for example, the added extension and loading should give you smoother low end. Though of course, every vehicle is different and this is a generic enclosure design, being not vehicle-specific.
So The $150 dollar mark ain't too shabby for a little woofer with a ~90db 1w sensitivity.
Note* In this enclosure, the woofer will mount inverted and max out around 200w xmax wise. It will need a subsonic set around 35hz to keep it safe.
My paycheck has been held due to weather so Ive yet to build one. If anyone else wants to give it a shot I would love to hear the results. I could also do a low-end extension enclosure for the woofer if anyone would like, though of course at expense of good sensitivity (around 6db lost for 30hz or lower in a normal ported box)

amp. It has a predicted spl of 125db. In car, Im guessing the goal of 130db is entirely possible.
