Low Down Sound 15/6.5 Cab

#323
The 18Sound mid driver has puh-lenty of top end content...but, it's a different flavor than a horn would deliver.
It would be nice to be able to add (or turn off) the top end sheen the horn provides.

I don't believe the shorter LDS design cab I have would support adding a horn, let alone the mega sized bell that the lastest GB versions have.

Yar, I don't really think I want a horn but I am a techno nerd and if I get a second cab, definitely gonna stick the huge monster horn in there just for kicks ;) Gonna have to wait and see how some of my other stuff sells. Come around to the idea of wanting two smaller cabs I think.

Two smaller cabs is a workable idea, for sure.

Having used my LDS designed 15/6 several times now, I'm fairly confident in saying that if you hit it with enough power, it's as good a one cab solution as my:
AE410, 410UL, LDS2x12+2x6
though all of those are really different flavors.

My needs and preferences may be different that y'alls, but the only time I use two cabs anymore is using two much smaller ones. My two LDS 2x8's stack into a nice 4x8 line array. I used to haul two Mesa Diesel 115's at times, but as nice as they sounded it was quite a bit to move.

I intend for my 15/6.5 to standalone. You think 800 watts into this cab is enough? ;) I have a Carvin BX1200 on the way...

Yeah, the PA situation here in Phoenix is weak sauce, and our band has a bose PA - so the bottom end is garbage. So any show we can't rent a real PA, I have to carry wherever we are with my cabs. I'm gonna see if my Iamp can put out enough juice and if not, will decide whether to get another cab or a bigger amp, dunno yet.

We played Tempe Marketplace last week and the LDS cab woulda been plenty there cos we had a pro running sound with his monstrous Carvin PA but I dunno if it would have carried without. Huge outdoors and stuff. I'm looking forward to giving it a run in the fall as we've got another show there.

rp: we use one bose stick and a sub a lot, so my backline is the house, a lot.

"how much is enough, watts wise."

well, I gotta say, I do feel the 8 ohm nature of this cab.
my walkabout is one of my go-to heads, and it sure doesn't push this cab enough for me, and I can feel the M6 choking on it a bit.

the F1 does ok with it; which is weird because I've always felt the M6 had bigger guns inside than the F1, but they behave fairly similarly powering the 15/6.

bridging 1200 watts of wt800b into seems to be a good thing.

I'd have no qualms using either my 1602 or 2402, bridged, with preamp of choice with it...which is not to say "turn it all the way up and jackhammer it," but, clearly, the cab like some juice.

It should be more than sufficient.

How did the weight on yours work out? One-handable?

Responding to a number of posts all at once.....

I was very impressed with the volume and fullness of your cab (and also the other one I tried that Chef has now) with only the 300 watts of my MB F1. The low end was full and non-compressed, even when slapped. My big test for a cab is to compare the lowest fundamental tone between a plucked open E string and a slapped open E string. You shouldn't be able to hear any difference in the deepest region of the note between slap and fingerplucked style. That was the case with this cab. Slapping added all that transient attack, but did not result in either the amp or cab compressing (i.e., losing deep low end). Very nice!

You cab has a bit more oomph than the other one I tried, given it's a bigger box, but they are pretty darn similar. Without doing a side-by-side, I can't really say that one crossover design sounded significantly better than the other. I guess if someone put a gun to my head and said I had to choose, the 'new' 800 hz' crossover that Don put in your box sounded very smooth, and provided plenty of brightness. I did find myself cutting my upper mids a touch (the 800hz upper mid control), but I do the same thing with quite a few cabs.

However, I don't want to start a crossover churn again, since the boxes were quite different in a number of ways (porting, internal volume, and general vertical versus horizontal configuration)

Your cab is nice and lightweight. It surely is light enough to do a one hander, but quite frankly, it's big enough that I would find that cumbersome. If you have the cash, get a Kart-a-bag Super600 and you would be VERY happy with the schlep. It's also stable enough (i.e., big enough depth and width) to easily add castors.

Again, VERY nice cab, and I will again congratulate my friend Greenboy on the basic design. It's a beautifully even sounding cab from top to bottom, and I'm sure for those that need the super sizzly, adding a little tweeter crossed over way high wouldn't be difficult.

Nice, nice, nice IMO!

Interesting point on the F1. I find the F1 and my Puma500 to behave at least somewhat similarly through most cabs (the F1 is a bit louder and punchier, but not much). Into 8ohms and these particular cabs, the Puma500 rapidly runs out of headroom (i.e., it still sounds great, but literally just stops getting louder), while the F1 just ROARS for some reason.

Thanks for all your comments and thoughts guys :)

I am going to be hitting it with the IAmp of course, might try running a 40hz highpass into it or something for kicks if I see any volume issues (though really my Iamp is startlingly loud if you juice the input enough, seems to have a pretty tough input section).

I will probably wind up just two-pawing it for schlepping, or maybe getting a rolly cart or something.

I actually was thinking about throwing a tweeter (or two) in there just flat high-passed around 5khz or so, accugroove style. I really dig the sound of the titanium tweeter in my Drb cab - it's one of the best things Marc did with these designs, adding a relatively low sensitivity sparkly top. But for this cab I'm going without to see if I even need any more and if I do, I'll get another one :> Gig money's going to pay for this one pretty quick and if I can sell any of my other stuff, should be no problemo.

I should be receiving mine tomorrow.

Dimensions are 21.5"w x 25"t x 18"d with the mid centered above the 15" and four corner slot ports.

The ports will be flared/rounded off inside. He originally said it wouldn't add that much to the sound so we agreed not to do it. A month later he said he was able to do it.

I'm looking forward to receiving it.
