Design Goals:
loud deep bass on the cheap.

264-919 Tang Band W6-1139SIF 6-1/2″ Paper Cone Subwoofer Speaker

only used half a sheet of mdf. painted with whatever white paint i had lying around.

Tips & Tricks:
cut all the pieces accurately. this is more complicated than a ported box and the pieces have to be precise.

i couldnt be more happy with this sub, not boomy at all. ive thrown everything i have at it from jimi hendrix to some old school bass testers just to see what it could do. it can play it all with ease.

    I built this a couple of days ago. I used 3/4” birch ply with maple veneer. Absolutely phenomenal results. I’ve got it hooked to a 2.1 system on my TV. The bass is huge but it’s also very natural sounding. People talking sound natural but when it’s an action scene or a concert, look out. The bass is massive but smooth. I need to build one (or two) for my car now.

    Hmm.. I build this design with the same tang band 1139 (even tried the neo magnet version) but discovered way too much air noise from the back of the driver frame. The vent holes in the steel frame are just not large enough for quiet operation at medium to full excursion. Will be trying two different Wavecor drivers and an SB Acoustics one that fit the box. Not many options left to fit the 7″ wide inside panel. The box design is good though, I feel.

    I would line the internal walls with light absorption because without anything, there is way too much air noise. Huffing puffing.
