I have a prototype Billfitzmaurice Design Omni 15 bass cab which was my first O15 cab build which I put together as a prototype.
Anyhow - There's not enough space in my workshop now and seeing I make the new configurations of the Omni 15 ( still perform the same ), I'm prepared to let this go for material cost - so it's a bargain for someone.
This cab spanks the pants off a 410 - go to http://www.billfitzmaurice.com for specs and click on the forum for reviews etc.
Weight -about 29kg
Woofer - Eminence Kappa-Pro15LF
Mid - Eminence MR8
500 watt - 8 ohm
Note! HORN LODADED - so it performs MUCH better than a std radiator cab.
Crossovers fitted using top quality Erse coils and poly-caps
Hours played at gigs/demos - about 12hrs total
Now, being my first Omni cab, the carpet job isn't all that flash compared to the standards I like, but you have to look hard to see the flaws.
