david_e_m made a post in this thread: 8" or 6.5" tower speaker?Surface area rules in an open field environment and based on surface area one 8-inch speaker is nearly like having two 6.5-inch speakers. Plus, you will undoubtedly have more pod displacement with an 8-inch speaker and that determines the low freq...

david_e_m made a post in this thread: Anyone cut vent hole(s) 4 sub under port dash?Eric,
In order for the vent to be worthwhile it has to have considerable surface area....at minimum equal to the size of the woofer....but given the size of the port locker, ideally the vent should be even larger.

david_e_m made a post in this thread: 2 12L7's in a MalibuLet me add another scenario to Phil's example.
Let's say the first woofer is direct radiating into the cockpit. The second woofer is side-firing against the hull and into the under-helm cavity. The second woofer 's phase response is a summation o...

david_e_m made a post in this thread: 2 12L7's in a MalibuJohn,
First you have to get the 12L7 Thiele/Small parameters. You at least need their recommended internal gross enclosure volume. You'll simply double that displacement for two woofers. Phil with Kicker is on here frequently and extremely helpfu...

david_e_m made a post in this thread: Drivers side sub enclosures.Daniel,
That particular enclosure is down-firing so the enclosure was elevated off the sole as much as was possible, but certainly limited. To be honest, it didn't sound as good as it could....but it was what the boat owner wanted as a show piece...

In the two underdash plex sub enclosure pics that I posted, the enclosures and facade are elevated off the sole so that your feet slide under the enclosure for more leg room.
