Guys,
    I had ordered DIY kit for eD A7s-650 subwoofer. Estimated another 2 weeks to receive the item. Total weight for the whole subwoofer should be around 200lbs.

Anyway, I need help to source for Titebond II wood glue. Kind of hard to get in Penang. I asked my friend to look in Ace Hardware Puchong but he only manage to find the Titebond I.

Below is the wood glue I need for the project.

I'm still deciding either to just paint the subwoofer with wood paint or laminate.

if you don't mind me asking, how much if the total cost for the DIY kit? any links? as i searched ebay and didn't find any eD A7 nor eD A7s
and how much did you paid for shipping?

eD sells driver only if you want to DIY the cabinet. Maybe built a twin 18" sealed sub like their eD A7s-900. This is a monster. Twin 13" is only slightly better than single 18" (based on total surface).

as i thought.. elemental designs are marketing the same sub for both car sub and room sub.
the drivers used in the A7s - 650 are the 13Av.2, which is marketed as a car subwoofer.

guess a long throw car subwoofer does make a viable choice for room sub after all. easier to source locally, and i reckon a cheaper alternative for initial test builds.
will start looking into it after i finish my current project.

Spec wise I believe Velo DD-12 is 18hz to 120hz +-3db. SPL should be around 110db max. Advantage for Digital Drive series is the Servo feedback (adjustable) and built in EQ (something similar to SMS-1). A7s-650 measurement is 16hz to 100hz +-3db and able to exceed 115db. eD definitely will be better in terms of pure SPL and low extension. Not sure if it would be as musical as Velo sub without the servo feedback.

can't wait to hear your comparison for a DIY (even when it's semi DIY it's still DIY in my book) sub against a commercial sub.
