im looking to build a tapped or folded horn for a single 8" jbl gto804, ive built a tapped horn before for two 6.5" subwoofers and it works brilliantly, but it lacks in the low end, i dont know how to design them i had someone do one for me and i was hoping for the same again,

ive got someone designing me one at the moment, the they said the jbl doesnt have a good flat response in a t-line or a bandpass but good response in a ported box, but i love the bass production of a horn, i didnt want to have to buy a new subwoofer if i had to, just make do with what ive got ?
An externally hosted image should be here but it was not working when we last tested it.
This driver?
As previously mentioned it looks good
What about the previous TH was not good enough?
What driver and box design did you use?
yeah that jbl, the th i have now is brilliant for quite listening, but as i turn the volume up it doesnt perform idealy at louder levels, but then again im using cheap skytronic 6.5" woofers, they're 8ohms 125watts rms and ive got two in parralel, ive got the plans on sketchup but i dont know how to post them in here, its tuned to around 35hz and goes really loud and the low end, i'd like to use the jbl and tune it to around 30hertz or lower if possible without having a big box
Got any info on the skytronic woofers?
You can post the hornresp model text export in a
You can upload your sketchup model to the google 3D warehouse directly from sketchup and post a link here, it's under File>3D Warehouse>Share Model.

code box, that's the # tag in the advanced post editor
If sombody was twist my arm I'd build a new one, with a new/better driver.
What to look for, a low Q Sub woofer?
Hi Doug,
What direction do you want to go - lower, louder, fatter response???
I've made room in my inbox
dual 6.5" woofer th by 2009thread1 - Google 3D Warehouse
hope this works, the woofers are - SkyTronic 6.5" Woofer with Kevlar cone Subwoofer: speaker price comparison - prices at idealo.co.uk
ive got two in parralel on 250 watts rms, but as they're cheap they make some machanical noise at high xmax

This one?
Attachments
yeah those, two of them.This one?
for 11.99 each and there power handling i thought it would worth the attemp, they've held up good so far
im looking to do a tapped horn or folded horn, i prefer the bass from them compared to the rest, for listening to its clean, loud and most importantly lowI've got a pair of JBL 10" subs - GT1041. Works very well in a Bass Reflex. Outstanding performance. Dynamic and detailed bass.
