Eminence Kappalite 3015

the superior top end extension of the 3015 makes it a better choice if there will be no midrange driver.

True, but that's a whole 'nutha can of worms. IMO those who insist that they don't need a midrange driver have never heard a midrange driver. In fairness, that's not their fault, since bass cabs running a fifteen and a six or eight are almost non-existent.

Now there is only one issue I have with these speakers, they just don't go low or deep enough. Well for me at least.

That's the fault of the cabinet, not the drivers. But, since when the cabinet was designed drivers with the 3015s capabilities were three decades away, to be expected.

So, the better choice for the Carvin is the 3015LF, due to the midrange speaker in it. Still, the crossover is at 500, not 800. I will have enough power to drive either one to Xmax.

I don't see any issue crossing over at 500 instead of 800, jnewmark. Usually the limiting factor is how low the mid can safely be crossed, and evidently the answer is 500.

Thanks. having a hard time trying to decide what speaker to get. I really don't see myself driving either one to Xmax on any of my gigs, so maybe just the 3015 will do.

Like I said my 2x15 kappalite 3015 cab is a good all around cab!

Compared to my SVT 6x10 brand new out of the store cab.

I would of had much more fun burning my money then buying that SVT garbage.

I'v also owned 4 different 8x10 SVT cabs and I'v played trough 20 different ones. There was only 2 I ever liked and it was the gray cloth older SVTs single 4 ohm input. I'm not sure if they were late 70's or early 80's ones.

Now this is where you and me will never agree because my perception of low end will never be the same as your perception of low end.

I've had people come up to me after our set and say "man I came up to the 5 feet in front of the stage and I had to leave, it was so heavy you almost made me puke" or "man I just got full body massage after watching that!" while I'm thinking to myself I could go lower if I had so and so...

I currently own a 2000S SUNN cab the biggest 2x15" cab ever made by SUNN loaded with 2 JBL 140D's and that thing has nice low end but the low end I really like is the low end I'm getting from my 18"s but I think it's time for them to get reconed.

Anyways I have access to 6 2x15 cabs at the moment and I will swap out the Kappalites and put them in my 2000S SUNN cab and I'll see if there is a huge differents in low end department. But I'm pretty sure it's the speaker.

I do understand that cab design has a lot to do with the sound a particular speaker produces. I've seen it happen many times.

And the cab that I have the kappalites in is one of my smaller 2x15 cabs. I've taken that into account I still think it's the speaker that's limiting the low end.

If I was to rate the low end out of 10 it would be somewhere around 7 maybe 7.5 but I really wanna be close to 8.5 or 9.

It's not a huge difference but it's enough to make me notice.

This is very hard to explain cause it's such a small difference.

how would a 3015 do low-end wise in an old mesa diesel sized 1-15 bill?

I understand that a 3015LF & midrange (would a 6.5 generally be preferable to an 8, or is this purely subjective?) will outperform a 215 from yesteryear.

...but would a 215 using 3015LFs & midrange(s) give significantly more output than a single 15 & midrange? Or only marginally more? Would the two 3015LFs, even in an array, somehow "get in each others' way"?...

...and if the 3015LFs' 215 wouldn't get in one anothers' way, would a single 6.5 (or 8) be the right way to go, or should there be two 6.5s (8s)?...

Iualum, if the cabinet volume is sufficient, two 3015LF's will give you 6 dB more output than one alone. They won't get in one another's way. As for what to use for midrange coverage, offhand I can't think of any single 6" or 8" that would "keep up" with a pair of 3015LF's. Either diameter will work well as long as efficiency and power handling are sufficient.

Now if you only have enough cabinet volume for one 3015LF to perform well, shoehorning two into the box will play louder but you'll lose bottom end extension and the upper bass will probably be over-emphasized and muddy.

Potentially yes, but a single 3015LF in a well designed cab will provide as much low end output as anyone could possibly need. That includes playing to thousand seat rooms with no PA support.

The thing about the 3015LF is that it can really take 450 watts of juice without bottoming out, in a proper sized cab. Very very few speakers actually do that with low frequencies.

My hypothesis would be that you would really need to be throwing 900 watts at the 215+midrange to get a significant increase in volume (3db).

The thing is, since most quality midranges are significantly (3db-6db) more sensitive than a single 3015LF, one midrange can cover two 3015LFs if it's crossed over well.

So getting a pair of 3015LFs with a nice midrange is about 20lbs heavier than a single 3015LF with a midrange, so if size is not a big issue and you don't want a modular rig, you can save a lot of weight and money by getting a 215/8 or something like that.

You could expect to save around 2-300 bucks by buying a single cabinet, and also be able to utilize neat stuff like dolly casters without having to pay twice. In my case, I got a Dr. Bass 215/8 (3080) and saved around 500 bucks if you assume I put dolly casters, kickplate, and skid rails on both 115s in a modular rig. Plus it comes out to around 75lbs instead of 90.

how does the new Carvin NE15-8 / NE15-4 Neo compare with the 3015 ?
Click to expand...
That could only be answered by Carvin releasing T/S specs on them. - 15" Neodymium woofer
- 3" Voice Coil
- Power: 600W @ 4 ohms
- Rear Vented
- Freq Resp: 35-3kHz
- Net weight 7.4lbs.

 is not sufficient information to draw any useful conclusions.

I've read this thread and it seems like the 3015 is the choice for me. I have a marshall 1552 cabinet ported with 2x15's. The OD of the cab is 29.7"x29.3"x17.5". I found a site that calculated volume but it didn't include the 5" port......it told me the volume approx. 7.25 to 7.75 cu. ft. depending on the size of the plywood and taking the installed drivers into consideration. I'm new to cab/speaker design and there is a ton of info out there so thanks to everyone here posting info, it's overwhelming and helpful.....

thanks much bill. i have a old kustom 2-15 and i was thinking about a pair of neos for it. it's now sporting a pair of d-140's, but wonder if a pair of 2515's would fare better....
