Yeah, both my B212s came in FedEx but I was wondering about that slight added weight with this new 3-way. But yeah, I'll check first. Thanks, MD and Mike.

Damn, $399!
Sure my fEarful 15/6 is lighter, has a better mid, and a more robust xover.. but this cab is 4ohms and $200 less then what I paid to DIY ... wow.

I'm wondering if the OEM 4ohm 15" is the same basic spec as a standard 3015LF, or is it perhaps something more like a 15" version of the 4ohm 12" that AudioKinesis uses in their Thunderchild cab?

Sweet! Looking forward to hearing your thoughts on it.

I agree, $399 is a pretty tasty price. I've been looking for a 1x15 to go with my "new" 1972 Ampeg V-4B and I've been debating between buying a cab or trying my hand at a build. If I could get one of these in black tolex with black/silver grille cloth, it might just be a done deal...

5sg.

Just sent Dave an email with regards to a timeframe before the cloth is available. He has been super helpful with my inquiries, and prompt to respond. I agree though, the tolex/cloth is butter.

For 399, it answers the 'what do I use it with'...get two of them. There are a lot of people new to the concepts that this cab is 'designed' around, and one of them is to limit the chance of odd filtering and canceling that can happen with mis-matched cabs.

2x8ohm cabs with the 3015LF can reach brutal volumes and depths in a well braced box of the proper proportions.

Someone said that you need an 18" for reggae? Really. Because I've never owned an 18 and its pretty much what I do. For many years I used a decent 4x10 without a problem and shared it as backline without any complaints. Speaker size and how low it goes are mutually exclusive things. They don't impact each other.

I just said I wouldn't want to play reggae without MY 18"

Outstanding intro price!

 

[sleepytime]

I just ordered a 4 Ohm!! Done and Done!! My amp goes to 2 Ohms though, so I can still stack if needed, but get full power @ 4 into one cab.

Glad to see someone finally ordered one. Looking forward to the report.

Drop by and visit my 15/6+15/sub rig and you may change your mind.

$H!T quite the drive SKIES! I would love to tho, man that sounds like the BEEZ NEEZ <avatar joke I'm sure if you play reggae I need to look into downsizing/upgrading!

Well, given the cabs are good for about 1kw each, one weighs in the low 40's and the other is in the 50's...and the cabs reach LOW (and flat down there). In a number of situations, the soundman has pulled me out of the sub because my cab was cleaner and louder and just as low or lower. If Dave's 15-6-1 is 75% of the magic of the GB design, it might be your 18 killer.

That's the conclusion I've been coming to. 2xTB153 and 300 all tube watts. Yes please.

Can't wait to get it and let y'all hear it!

GB mentioned something a few posts back about the horn placement not being ideal. Can someone explain?

For sure. The black/grille cloth would match nicely with my V-4B.

It's kind of weird to me that options aren't already available. I mean, same box as the B212, right? I guess I was under the impression that they do the finishing at their shop... one of the guys called me to let me know they had to redo the tolex on my 2x12 and they sent it out the following day.

No skin off my teeth either way really, not ready to order a cab yet anyway. Just a curiosity.

Thanks - so 1wavelength at the xover freq. (between horn and mid driver) would be about 3" to avoid comb filtering. I think I understand. Does the same hold true for the relationship vertically between the woofer and the horn/mid driver above it?

No, as any combing that occurs would be on the vertical plane, where it doesn't matter. Spacing should be as tight as practical, but it's not critical.

 

[greenboy]

I find that tight spacing is a big advantage on both planes, and what was already tight in my revision one plans got tighter yet in my revision two plans.

The odd thing about BASS GUITAR systems, is that you can't really depend on people having the cabs at any particular angle relative to their ears, nor can you depend on them having the midrange driver and the woofer EACH being about the same distance from the ear. One is often much closer. Espeically in the range that both drivers reproduce due to crossovers not being brick wall devices, this seems to matter.

But even outside the crossover region there seems to be benefit to having a smaller "source area"...

In acoustic sims, closing the distance between the drivers vertically seems to help all the placement variations sound more similar to one another, even when pretty close to the enclosures. Both live use and critical listening has borne this out to my satisfaction. More variance in positioning of listener relative to cabs has less variance overall sound quality.

Anyway, I'm no genius, but in practice over a lot of gigs and again at home with critical listenind in more controlled conditions, this is what has worked best for me:

This is actually Tom Bowlus's 12/6--15/6 stack. Notice that each cab has drivers practically touching. Using a different waveguide in the same cutout hole, there would be about 2 mm between each outer component, provided all cuts were on mark. With the slightly smaller waveguide they still are very close.

Note that mirror image baffle for one cab. That's what I've found is almost always the best way to go with these.

... you know what?.. I live in Florida...and yet the best roots reggae I eva heard was in Buffalo NY...
They did "hard man fe dead" and Dawn Penn's "no no no.." Still get the chills when I think about it.. Maybe you "feel" the reggae more in the cold than we do down here !.. yeah.. and i agree... 10's and 4-string can go low enough for reggae....reggae is all about the spaces between the notes !

This rig is the answer to the question, "Who is number one?"
