I just picked up this sub / enclosure combo for a great price but unfortunately it's more designed for SPL (used to be in a car) and not so much for sub 30hz movie watching. Originally intended to ship an SI 18" from the states due to the lack of 18" subs here in New Zealand. But high shipping costs (almost the same as what I bought this setup for!!) led me down this path instead.
I'm looking for some advice on how I could possibly tweak this enclosure to sound cleaner and deeper for my movies ? I'm pretty sure I'm going to be limited by my subwoofer specs, you will see my fs at 37hz is quite high.
But I was wondering if the knowledgeable enclosure builders out there could suggest what I could change to improve its sound ? Should I add some insulation ? if so how much ? What would plugging the ports do ?
I have tried a test tone and it sounds really nice down to 27hz but anything less than that the sound level drops off and quality diminishes.
The enclosure dimensions are 95cm x 60cm x 44cm (excuse the metric I'm from New Zealand) converting these units I get 8.85 cu ft (outside dimensions).
I'm running a Behringer ep2500 bridged @ 4ohms, sub is rated 1800w so a good power match, easily pressurizes my high 25ft ceilings.
Excuse all the glue marks.
