Hi Thawach
What you have built is not a jbell SS15 but an early attempt by me, to meet jbells Single Sheet Challenge. The Cube shape was rejected, and a rectangular profile as used, with a different fold to increase the path length.
Here is a link to the SS15 plans.

As you say with this cube TH plan, the bass is 'Soft' but the mid bass, I hope, is 'Loud'

The photo you have posted of jbells TH cabinets is another bigger design

ive just been downloading. all my friends seem like the tapped horn in pa. many designs from me now they seem don't like. they only want the tapped horn design. they never listened the TH before when someone built. they listened and like it. two plans ill waiting someone to build. thanks tb

Thawach · 2011-11-30 11:06 pm

just measure 0.5 tsw-218 today. use the P audio P180/2242 new series. i try to use the simple sysrta to measure. ok it looks good but only freeware. the box only paint wood primer one time and still paint it again.

Thawach · 2011-12-01 12:47 pm

@martin, i'm surprise about the cube th plan. why to use the 12 mm mdf thick. strong enough? and another Q i want to know u use any dsp brand to cut off the low freq problem of the tapped horn. thank u

Thawach · 2011-12-01 4:18 pm

my friends like the light weight if 12 drv can use the 12 mm. i think bracing a lot. ok the 12 mm may be good.
