Since good things often come in multiples heres another cab to add to my collection.

Omni 10.5 with Deltalite 2510 and BK plate amp.

I needed a new backline cab as my old one (see final pic) is getting a bit tattered and is an awkward shape to move around! Its still great though - 2x10 PD loaded + Powerline Piezo.

So I have finally got my arse in gear and got this new BFM cab to replace it with a built in 600W amp.

I played out with it the other night, in a local trades and labour club with a covers band....

Hmm problems.... I couldnt get it quiet enough, I had to turn down the gain on my keyboard, for some reason the plate amp has a minimal gain setting that isnt quite 0, and on heavy organ sounds, it was a little too loud.

I have never been used to hearing myself so clearly so it kinda scared me a bit!

Overall the sound was good, a little less bassy than I am used to but thats ok, the cab is on a kickback stand so that would explain why.

I can hear myself a lot better though, the lower notes on the piano seem somehow clearer, despite not having as much <100Hz output as before, plus the cab is now pointed up at my ear which is definitely an improvement.

I want to get a cheap 9/10/12 band EQ at some point to have a bit of tone shaping EQ potential so the response can only get flatter

It also weighs next to nothing with a Neo driver and digital lightweight amp!

So very useful, very flexible and pretty cheap, certainly much better quality sound than if I had bought a purpose built keyboard amp, plus its a horn, so everything just sounds cleaner and punchier.

Just below the driver in the second pic is the slot that ports into the throat.

Why does it vent to the outside aswell then!? seems odd, or is that a secret that only the purchasers of his designs get to know?

It doesnt

If you mean the vertical strip down the side of the cab in the 2nd pic, thats where the tweeters go.

That would indeed be an enormous port for a 10" box, you would have to expect some performance from a 10" to warrant a port that big.
