Need more power? A pair of Deltalite II 2510 woofers takes you up to a whopping 500 watts, while the cabinet still comes in at less than 50 pounds. But despite its small size and weight the O10 is no slouch in the response department. This cab has bass power that you usually need two twelves to achieve. Take a look at this 1m/1W SPL chart, comparing the O10 to a larger and heavier Eminence Delta loaded 2x12 w/tweeter:

If you've already got a pair of tens and can't afford to trade up to a bigger rig just pop those tens into an Omni 10. With the average 5dB advantage it has over commercial cabs it will be like having triple the watts. Read what builder Dave Tenney thinks about his O10:

"I've been playing bass for 17 years, and for five of those years I played an average of 120 gigs a year. I've been through many amps...Ampeg Portaflex and SVT and just about every classic series cabinet they made (2x10, 4x10, 8x10, 1x15). Unfortunately my two favorite cabs were the Ampeg 8x10 and an old Peavey 2x15...Way to big and heavy for me anymore! The best ones I have owned had two characteristics that, to me, made them great. The first one is that the cabinet has to have a certain presence in the lower midrange. If the cabinet doesn't have any "Honk" (My word here...Think Jaco's tone) you can't hear it on stage. I avoid cabs that have that scooped out midrange sound...They just get lost in the mix, which really sucks when you are playing fretless. I've also found that you can't really add the "honk" back with EQ. The second thing a great cabinet has to have is an even tone. When I play a Chuck Rainy style double-stop up on the 14th fret I want it to be the same volume as the stuff I'm playing in the first position. The good news for me is that the Omni 10 has both of these characteristics-! I am really impressed with the way this cabinet sounds. It also has waaay more output than ANY 2x10 I have ever heard...More like a 4x10. I built mine with BP102's. I compared the cabinet to my Redhead which has the same speakers in it and there was no comparison....The omni completely overpowered the 2x10 SWR ported cabinet. Low end wise the omni is plenty capable for electric bass. I think this is going to be a cabinet that I will be able to live with for many years..."

Like the O12 and O15, the O10 is an easy build, even if you don't own a shop full of power tools. All you need is a circular saw. An electric drill would be nice, but if you haven't got one don't worry, this puppy will go together with a hammer and nails.

Like the DRs, multiple O10s can be vertically arrayed, but for even wider dispersion they also can be cross-fired. Unlike the DRs, you can build a half-sized O10.5, loaded with a single ten. That brings the size down to 14x16x20 inches, and the weight to 25 pounds. And the build cost? You can do a full sized O10 loaded with a pair of MCM 55-1740 woofers for about $150, complete.
