Item: pair passive 30hz tapped horns, Will Cowan design, built by Paul Spencer with brand new never-used 12" Eminence Definimax driver Location: Kinglake West, VIC Reason selling: Not using. Condition: DIY, never used. Pickup only, COD Price: $650 for both horns and both drivers. Firm. I had Paul build me two of these last year but my plans for speakers took a different direction so haven't had the need for these. The drivers were bought brand new and haven't been installed, other than Paul briefly installing one to measure the finished subs. Some plans and graphs can be seen here http://www.cowanaudio.com/th.html The finish is fairly rough, form ply, the subs designed to be out of sight, might benefit from a sand and paint.

The sale doesn't include any driver, I didn't get as far as buying those. The kit crossover kit cost me AU$612 (US$445.88) landed. https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=6&ved=2ahUKEwiQtaGy89DdAhXSdt4KHbrrB_wQFjAFegQIAhAC&url=http%3A%2F%2Fforum.vegalab.ru%2Fattachment.php%3Fattachmentid%3D251471%26d%3D1448362988&usg=AOvVaw05-9r4P5g-nPKK_LRpg-fa

Thanks Dave. I had been running a pair of these drivers in sealed 110L cabs, with EQ down to 20hz, but they bottomed out on one or two tracks. Now I'll use them mostly for movies as I'm building some floorstanders that go down to 30hz, so figured I might aim for proper HT subs for just the bottom=most octave..

Hi - hoping someone can run the numbers and confirm my math before I start cutting. I'm rehousing a Dayton Ultimax 12" from a large box into something tall and this that will be mounted into a wall. I can pretty much make the volume whatever I want, but shape is flattish, about 45cm wide, and floor-to-ceiling in height if need be. I'm wanting bass down to about 16hz if possible. The only calculator I have is the online ml-audio one (dont know any program that run on OSx), I'll attach screen shot. It seems to suggest 154L, and I need a port with total surface area of 57.55 cm2 and length 28.84cm to get -3db point of 14hz. I can only fit in a slot port I think. The calculator says "The bass reflex port should have at least 1/3 of the driver's diameter!" - I assume a 43cm x 1.33cm wide port will chuff... How does 10cm x 5.7cm opening x 28.84 long seem? Thanks for any help with this, Bevan ps, the 'plot frequency response curve' doest work on my Mac (Java problem), can I assume the above tuning produces a reasonable response curve given that the box size and 17.88hz tuning is what the program suggested?

Weedgie, bit ugly atm, but so far kept him away from the glowing screen. He's only a crawler but I had fears of him one day taking the diffusors for a climbing wall. Louis - I realize I did forget some pertinent info - they are passive in the mid/tweeter, i.e. the horn runs off a single amp, but the bass is active. I forgot to take this amp into consideration in both the cost price and selling price. I have a Minidsp PWR-ICE 250 I can sell if needed, say 2/3 of what I paid for it which would be about $340. I had good results with a 2W EL34 on the horns. You're obviously welcome to come give it a try. Cheers Bevan
