Thanks again for you help Jason, according to the specs, recommended sealed box volume for the MW160 woofer I will be using is between 7.1 and 21.1L. Here is a link to the specs:

I'll try and get in touch with manufacturer re. ports etc....7.1L may be achievable since I am using the space in front of the pedals etc, but 21.1L would be impossible!

Retaped the interior this arvo and applied another two layers of fibreglass matt (trying to minimise resin use!).

Think about 3.5 two litre bottles per panel. That's a LOT of volume. Your right, you can only get that if you wrap around. Again though, go through pedal travel with some big shoes on, make sure you have plenty of room.

Picked up the new eclipse sub today - would have liked to mount it inverted but the rollcage gets in the way so it will sit like this. 6x9 holes will be glassed over soon.



Trimmed base for kicks (again) after second two layers was applied - nice and rigid now. Once I set the mdf rings in place I'll ensure I do lots of imaginary trial runs to make sure my feet clear - I'll even make some "broom broom" sounds for special effects

Not much work this weekend (going away), but will continue next week.
Cheers
Alan

Have you measured that the volume is correct for the Eclipse sub in that enclosure? Contrary to popular mythology, Box A and Subwoofer B may not be compatable. The box volume must be correct for the sub or you may have much less than enjoyable results, from just poor sounding bass to woofer meltdown. You can use Kitty Litter or just plain water if everything is glassed to calculate volume. Don't forget, once the volume of the box is understood, the volume of the speaker assembly must be subtracted from that volume to equal the actual working air volume that the subwoofer sees. Usually the speaker assembly volume is somewhere in the list of sub properties.
