Efficient sub for Omnes Audio L8's
 
hi, after recently making my new speakers with the Omnes Audio L8 full ranger in OB, i have been using my tannoy ts8 sub for the moment, but it cant really keep up, so a new one will be needed.

my main goals are that it cant be too big( max around 30L) relatively easy to make (open baffle would be good), dont need to rock the house, would rather have an accurate and punchy 40Hz than a boomy 25Hz (so quality over quantity) lol!

sort of like the orion bass (http://www.linkwitzlab.com/orion_challenge.htm)

budget around 300-400 inc drivers, amps etc.

any sudgestions?

Just about custom designed for your application and inexpensive. Regards Moray James.

isnt that the 12" version?

that looks good, and cheap to!

whats the best way to power them? (say one each side on the existing baffle) was thinking of using a cheap but powerfull power amp like the Behringer A500 (http://www.dv247.com/invt/25947 120) and an active crossover rather than two cheapish sub plate amps.

Maybe the Dyna-fone from Diy Hifi Supply: Dyna-fone (scroll down).

XLS10 and passive radiator, from BK Electronics. Maybe one of their plate amps too.

Perhaps what you actually need is a WOOFER.. not a subwoofer.

Consider using your sub somewhere below 40 Hz and perhaps the "Augie" dipole bass driver (or 2 of them), bottom of the page:

Of course you can also use a cheap plate amp for this as well.. Consider the MCM (you'll not find better for less):

(..the continuosly adjustable phase is particularly noteworthy at this price.)

For an actual subwoofer consider tha servo Rythmic sub:

Lots of options...
 
the XLS10 and matching passive radiator will take top place for performance Vs size but if you can stand a bit more volume you can buy two SLS12's for a lot less money and move more air. You would probably have almost enough left over to buy your plate amp to run them (100 watts ought to do). Good value all things considered.

but wont the 2xSLS12's need to go in a bigger box than 30L, the Auggies look tempting but might end up expensive shipping from the usa.

Dual SLS12...
 
have a look at the dipole sub at the Linlwitz site. This is about as small as you will find for a sub. Sorry can't do volume in liters, just not in my head. Cabinet would be about 14 inches high and deep by about 17 inches wide give or take (outside dimensions). Very compact for a sub.

inrank 17th October 2006 07:25 PM

well that might be compact for you, but my sub (Tannoy TS8) is 12L and about 11" cubed lol!
