Low Down Sound question

amelnick · #1 02-09-2011, 03:47 PM

Looking to get a 15/6/1 and want to stack with another cab on top for ability to go 4 ohms and added support for larger venues. Anyone have a LDS stack? What are you using? I was thinking of a 12/6/1 on top.

HELP!!!

How about a second 15/6 with a mirror image baffle?

A 12/6/1 might be cool if you play some small gigs like coffee houses and want to just bring a mini rig. As far volume, I can't imagine a venue where a 15/6/1 and a 12/6/1 combined at 4 ohms wouldn't be enough unless your in a drop tune metal band or something.

I don't use LDS cabs but I do have both a 15/8 cab and a 12/6 cab that make an extremely versatile setup. Just make sure your baffles are mirror imaged so that stacking lines up the matching drivers in a vertical array and I think you will be very happy with the results.

If the 12" sub handles less juice than the 15"one does, it will be your limiting factor. IOW, if you turn up to drive the 15" fully, you probably just trashed your 12". If the 12" you are looking at can handle a gob of juice then go for it. Otherwise I'd get a second 15" or perhaps a 210.

More speakers will almost always yield noticeably more volume. There is always the possibility that you wouldn't ever need to fully drive your 15" when using a 12/15 cab combo. Still it can be annoying.

Example: I used to use an EA cxl112/nl210 stack. It had amazing tone and was capable of some impressive volume. That being said, there were times when I wanted to feed the stack a little more juice but had the 112 at the max it was capable of handling as it handled less juice than the 210. So I was lugging around the larger 210 without being able to properly use it.

If you just want something different, what about a 15" cab sans mid drivers and tweeters? Just run it full range.

Or a fEarful 15 sub? Sit the 15/6 on top and you otter be able to rule the world!

I didn't answer your question, did I?

That's true, my 12 and 15 handle exactly the same power so it works for me. I didn't think about this aspect when I first posted.

One of our TBers uses that exact stack and loves it . He had the cabinets built the same width and did have them made so the mids lined up but without the tweeters . The two cabs pretty much sound the same and with the 3012LFs power handling make this a very good idea . No real downsides .

That is EXACTLY what I currently have on order with Don.....a pair of "tall" 15/6's with mirror image baffles. I plan to stack them on their sides.

amelnick: The TB'er that uses an LDS 15/6 and 12/6 stack is "Ukiah Bass". He loves it! You can find some posts by him (and lots of other LDS info) in this thread:

Concern is Don stated the 12/6 is 95db and the 15/6 is 101db.

PM TBer Ukiahbass-he has the LDS 15-12 nEarful stack and loves it. I have an LDS 15-6that's a carbon copy of his-amazing cab!!!!!!!!

That's just the laws of physics. Less radiating area, less sound. The difference in volume will probably be close to the difference between a 4x10 and a 3x10. As long as they're both the same impedance, your amp or cabs won't know the difference. The advantage of having two different cabs is versatility. If you want a small cab (easier to handle) to take to practice or a low volume acoustic gig, the 12/6 will cover you, the 15/6 will cover most small to mid sized clubs, and both together increases your radiating area and lowers your load to handle the big stuff like outdoor gigs. This assumes you have around 350 into 8 and 500+ into 4 ohms of good power to drive them.

Add a 1x15 loaded with the same driver as the 15/6/1. The next best bet is the mirror imaged 15/6/1 mentioned already. Anything else is less than optimal, and one of the reasons for custom cabs is so that you can achieve optimal.

rpsands · #14 02-10-2011, 10:44 AM

I'd do the 12/6 + 15/6 stack myself. Optimal is a matter of perception since for me optimal would be being able to carry just a 12/6 for half or more of my gigs.

Adding the 12/6 to the 15/6 gets you some additional height and volume.

To be fair the "real" sensitivities are more like 94db/98db.

tweeter/no tweeter???????

I have a 15/6 and a 12/6 built for stacking. And after all that, I rarely use both at the same time. The 15/6 kicks out HUGE sound. I use the 12/6 on "quieter" gigs. Lots of performance videos at http://www.youtube.com/user/TheStormyWeathermen

IMO no tweeter, one should suffice, and two can do more harm than good. Getting a pair of tweeters in two cabs to constructively combine their outputs requires having them vertically aligned and no more than than six inches apart. The mids should be vertical as well, but the spacing isn't as critical.

i use two 15/6.5 cabs , powered by various amps , to get the full 4 ohm grunt ...

with the Shuttle 9.0

with Stewart 2.1 powering an Aguilar DB659 preamp

... killer .
