Show your Bill Fitzmaurice cab

How about making an omni 10 with 2510's and then a half sized omni 10.5 with a single 2510. then you have the option of practice/small gig, med gig, bigger gig. still 3 drivers, still avg 2.7 ohms, but without any modifications and with some added flexibility.

Agreed, that definetly would do the trick, I just hate having two cabs... because the way i am, i will always bring both and then it will be an extra trip... maybe I should just stop bein stupid and just do a two cab solution...

Another thing...

I just got a good look at the Omni 15's chart, man that looks like an impressive speaker... ? how does the Omni 15 serve as a bass cab in say bars and clubs... its output seems to smoke the omni 10 a bit... and have a much broader frequency response...

Don't think for a moment that two 2510s in an O10 will replace an 8x10; I'm a speaker designer, not a magician. OTOH, two 2510 loaded O10s would give an 8x10 a pretty good run for the money.

Oh im not suggesting that at all, im just pointing out one of the reasons why i dont think the 010 would replace my gig rig :)

Im sure two O10s would give an 8x10 a run for its money, especially if you have them stacked. But ive been a big fan of sealed cabs for playing live for quite a while, so, im not sure if ill be switching over is what i was meaning :)

(altho, an O10 with a Titan? thats another idea, but, just something i really want to try out!)

As far as "my sound" goes, I'll use my 15" Carvin and my 212 Carvin for the studio tone. I'm needing to be heard right now. So I'm under the impression you built the OT2x15 and not the 1x15 and just kinda curious, is there a decent volume curve when turning up the master volume? Ie. volumeset on 4 is way to loud but put it on 3 and yu cant hear it or is smooth and predictibal as you turn it up. The reason I ask is I have a good friend that has couple of way older horn loaded Carvin 15's and they go from not so loud to way to loud real easy.

I built the 2x15.

I don't hear any spike in volume when turning up the master, but i've tried some amps that do this at a small fraction of a turn. If the taper on your amp is smooth, you shouldn't have a problem.

You'll definitely be heard with this cab. If you pan a little to the bridge pickup there won't be any mistake about your presence in the mix.

I have two Deltalite II 2510s en-route, that i ordered up last week, but, its going to take a lot to even get close to me replacing my 810.

An Omni 10 won't outperform an 810, so I wasn't implying it would replace your 810.

What I am saying is that it's so lightweight ( mine is 20kg - a one hand lift ) yet so powerful thus an easy cab to just quikcly pick up and drag along to a gig where it will do a mighty fine job.

Yet small enough to sit around home as a practice cab.

It will give a 410 a good run for its money though - we have an SWR410 at church and the O10 demo I have is a much nicer cab in terms of tone. I can't crank these two to the max there, but for sure the O10 is heard better through the all hte noise on stage than the 410 is.

The DR's though - they're in another league. Nothing much touches my DR280 even when used by itself - with a T39 sub underneath it's just insane!

The Omni 10 Looks like a good bet. I wanted something to define the high end a little more, The Tweet in my 2-12 finally crapped. I winded up just disconnecting it and now I find myself lacking in the upper and upper mid. I really just want something to define all freq. Though, I really like what my 2-12 does, I want more.

Echo...Echo...Echo!

Will the O10 get me what my 2-12 doesn't?

Dude...build a fully loaded Omni 12. Do it according to BFM specs. You will get more. :)

I can't, its more than I can spend. I might be able to scrape up the 150 for the O10, but I can't come off $300. But yeah the Charts look sweet on that one. Maybe I'll be allowed on the BF forum so I can pose my question there. I looked at the O10 charts again and it looks pretty good in the high end but really shines between 150-300hz. The db is crazy.

The O10 is most awesome yes. But you were looking or the full range and more. I don't know about what you have available. BUT you may be able to use 1 of the 12's then you need a 8" and a tweeter, wood, x-over and glue. Price it all out man! Before you have to say no. At least buy the O12 and O10 plans.

Check this guy out. For great prices and knowlege.

I just finished this omni 10 and it sounds great but I may be biased. 2 eminence S2010 drivers and a tweeter array. total weight- 42lbs

Just wondering how they would do in the cabs. The specs on this speaker go deeper (40 Hz) compared to the Delta series. And Mr. Bill, are there any suggested upgrades for the tweeter/ horn assembly iin the Omni/Dr speaker lines?

Your stuff is looking better all the time from what people are saying about them.

Thanks,

Cameron

Acoustic Chris, how do you you like the treble response from your eight tweeter array? Do you have an L-pad to fine tune it? I found the unattenuated tweeter in my Omni 12's to be too much for electric bass, to my ears. I had to go install an L-pad to get treble response where I like it.

One of the nice things about piezo tweeters is their sensivity is much closer to that of typical bass speakers, whilst compression horns tend to be far louder and thus need padding back. If you do need to pad back a piezo array, rather than using an L-pad which is quite complicated as the piezos represent a capacitive load and have to be turned into looking like a resistive load to work, you can simply wire the piezos in different combinations of series and parallel to get the sensitivity you need.

I believe you can use an piezo array in the Omni 12 and 15 cabs by offsetting the mid horn and running the piezos from top to bottom of the front baffle.

Thanks, Alex. I have a pair of Omni 10's in progress right now, and without your guidance I would have put an L-pad in series with the tweets, which is not the way to do it, right?

I decided to go with four tweeters rather than the eight tweeter array because I want a rounder top than a true full range speaker provides. I have heard of guys using simple on-off switches to cut the tweeters out entirely, and I may experiment with that.

Dave Carter installed some switches on his O10 and can comment directly on their usefulness. What do you say, Dave?

I hardwired the array so mine are one all the time. I really like the added high end punch. I never realized now broad the eq was on my pup until I plugged in the O10.

My amp has an 8 band eq bank so I can turn off the tweets by just removing anything > 4khz. I find this is very effective.

An L-pad would work (if you deal with the capacitive tweeter load) if you wanted some method of fine-tuning your array while maintaining your impedance rather than just on/off.

My 2 cents. I would recommend you wire the puppy up and then decide. It's rather easy to pop the back and insert stuff later.
