Has anyone heard the Kappalite 3015 yet? The 5.9 Xmax sounds fun with highs up to 4k
The 3015 looks real nice on paper.
Conservative highs to around 2,500 Hz.
2.75 cubic feet tuned at 45 Hz.
F3 around 65 Hz.
The 3015LF is a tad less sensitive, uses a bigger box, and gets down a bit lower. The high end is all done above 1,000 Hz. It has a lot more Xmax than the 3015 above.
4.6 cubic feet tuned at 43 Hz
F3 around 45 Hz.
Add to this that the 3015LF has an XMAX of 9.0mm which equates to a lot of cone travel available.
If I ever get to building my omni 15 you better believe it will have a kapplite 3015LF in it.
The best driver for the Omni 15 is what is recommended in the plans.
I've not yet seen the Omni 15 plans, so do not know which driver is preferred. Bill is on top of the latest Eminence drivers, and keeps the plans updated accordingly.
The 3015LF is killer for a Tuba 36. Ideal specs and light weight.
Yep. The 3015LF is a good driver if you want cheap lightwieght efficiency with decent extension in a fairly large ported box, but it probably isn't ideal for the horn loading in that design.
I recommend it in both the O15 and T36.
ok its been a few days...has anyone had first hand expiriance with this speaker yet?
correct me if im wrong, but xmax has nothing to do with a horn, although it helps. You basicaly want an efficient speaker ( a spec not published regularly) along with a low vas. true?
Sorry, that post was a brain fart; I was mentally thinking 3015LF specs on one hand while juggling some others at the same time.
You are wrong. First read Olson's Acoustical Engineering,
Then download McBean's HornResp program and experiment with it for a month or so, and then spend the next ten years or so building a few dozen horns. At that point you'll begin to understand what they're all about. I built my first horn in 1968, and I still learn something with every new one.
ok i just order a kappalite 3015 (non LF)
i should get it next week. I'll be sure to comment.
I did exactly that, and I am pretty much where I started. Figuring out Thiele-Small was comparatively easy.
anyone hear the kappalite 3015 yet? Mine should be here this wensday. I can't wait......
Looks like you're the TB guinea pig GE. We look forward to your review, good points and bad.
yes keep us posted. If it sounds great, i got a box that i might throw that thing in myself.
I just installed the kappalite 3015 in my cab (leslie 122). I had an EVM15B pro-line in there and thats what i will use to compare. Thats how good it sounds. I was expecting the evm to have more mids and i was very shocked at how simular the 3015 sounds in the mid section. The lower notes i play, the better sounding the 3015 is. the 5.9 xmax is really sounding great. The Evm is not going back in the cab.
Pros: Great bottom end. Awsome mids. Lite. Sound is clear and loud.
Cons: Not as clear as the Evm 15b at high volumes but i think i have to break it in more before i can crank it up.
This is my first post after lurking around for a bit. I have used the 3015 in 1x15 and 2 x 15 cabinets since the speaker came out. Play a HiWatt DR201 with a 74 rick 4001 and a 6 string Ibanez Prestige. After being a devote EVM15B user since the 70's, I feel this will be my speaker for remainder of time. No need for a horn on the highs and produces a very strong 32 hz sound wave through our own designed cabinets. The trade off in weight from 25 + pounds to 9 is just another bonus.
Great information on this site!!!
