Subject: Re: thats a horn.


it isnt mine :( i may build a similar thing for my mate who has the space though.

i know how to make a band pass sub and how to make a horn well, but not combined I could not find any theory or way to correctly construct that'
heh i DONT know how to combine bandpass sub and horn,it seems like they are just bandpass with a big port.

the picture is called 'labsub' ,2 of them infact.
they were designed by tom danley from servodrive.com
as a DIY free plans project.

30hz operation with 2 boxes against a wall
can use a few watts,or 1kw per box.

if you love woodworking i reccomend the LABSUB.
you could design your own if u want..
the labsub uses the LAB12 woofer from eminence.
it has 104db efficiency
it is designed for outdoor use in stacks,but in house it works fine in a corner,particurly with acorner reflector
if you want details,reply back,i got a txt file with all the data.

for pics,autocad stuff and plans


cheers
