Low Down Sound 15/6.5 Cab

...There was also no built in pad on the mid driver...

I'm starting to think my memory isn't as bad as I thought it was (although my documentation is in question). I took a look at the specs on the 6ND410 last night and with it being as hot as it is, I would have put some kind of pad on it even if I knew there was going to be an L-pad. I'll confirm when I get the box from Don.

I assume a pad would just change the level of the L-pad anyway, right? So, it's kind of a moot point. Not sure if I'm understanding Alex's post above correctly, but I guess putting an L-pad on a mid driver that is crossed over quite low is more problematic, due to all the juice/current/sound pumping through it. In that case, getting the pad level right would seem to be key.

I look forward to hearing what you guys come up with. Again, the current crossover, etc. that you came up with sounded very, very good to me with that L Pad at around 10 o'clock or so.

From our discussions, I think you would dig this design a lot. I actually LOVE the deep low end, but as you know, I prefer that more 'modern' top end consisting of the upper mids coming from my 10" drivers, and then extended further up by a high quality tweeter (Just personal preference there).

I know that these can be made into a three way design, so I'm still interested (I love trying all this stuff).

I tell you what, Don's passive 62 J Reissue was just SMOKING through this cab. That upper mid driver transmitted that upper mid/lower treble grind beautifully. And, as posted above, even though the cab is 8ohms, the SPL, etc. seems very good, and my MB head wumped pretty well. I think Alex has reported very good results with the LH500 into it.

Awesome, yeah I like a "vintagey" top. Good response up to 4-5 K, and after that I don't really need anything. I definitely don't like sizzle for my personal tonal goals, and I'm not sure I like "grind" either but I might not be interpreting that right. I like a smooth, sweet treble response with a little bit of bite and edge from single coil J pickups. I usually associate grind with pickstyle playing.

I think KJ didn't find it to be his cup of tea due to no horn.

He likes it pretty shiny on top, and a paper cone mid driver-even a great one-just isn't "that."

Thanks, do you like the upper mid/treble response out of your LDS 212?

I don't know if this is helpful, since we all come from different music backgrounds, preferences, and even generations, but if you dig Bob Glaub's tone on Jackson Browne's 'The Pretender', you will love these cabs... that fat, articulate, but still relatively mellow P Bass (or J bass tone), with plenty of brightness, but no sizzle at all.

Also, if you slap tone preference (if you have one) leans more toward early Larry Graham, you would also dig this type of cab voicing.

Of course, take into account that I've only heard one execution, but I have to believe the top end is at least somewhat similar across designs.

I can definitely dig that tone, and that's usually the tone I go with my P bass w/ flats. I just listened to the whole track, very nice P bass tone.

You would be very happy with a cabinet like this.

+1 And, a bit OT, but hey, it's my thread:D, isn't Porcaro's drumming on that track frightening. Legend has it that was a one take deal. I LOVE Glaub's playing and tone on that track (and really just about everything he did during that era).

Yeah, the L-Pad is one thing I am slightly concerned about with this design - a 100w lpad (standard I think) seems likely to be undergunned for the 700hz-ish crossover I'm using. Hope it works out - I'm sure Ralf won't put something in there that isn't able to handle it. And, I'm not going to be churning amazing wattage through there (500w@ 8ohms).

I think Alex uses an even quite a bit lower xover, but not sure - closer to 550?

I know this is Apples to Oranges, but I was just wondering
about the difference in sound between this box and the
Schroeder 15+L. I understand its a horn instead of a mid
speaker, bit I'm just looking for a reference point.

Also, Roger Baer has been using the 6in mid speakers with
great success too. Plenty of highs but not the sizzle on top.

Mine's still around 700Hz but the filter slopes are very steep.

When correctly implemented these 15"+6.5" variants sound absolutely nothing like any conventional 15", or any other cab, save one with a similar or identical midrange driver and similar end result from the crossover. The woofer size has almost no bearing on tone, just on sensitivity, power handling and max output.

The 2x12+2x6 is really a different deal.
It has (I believe) eminence 6's in it, and tho I've not heard the mid driver spec'd for the Fearful 16/6 design, it's my understanding that they're much brighter, more efficient, and much louder.
Mine dont' have an L-pad, so they do what they do, and that's...what they do. Which is about what you'd expect. Semi-subdued mellow paper cone top end.

I think the Fearful thing is likely to be much more aggressive, and thus, the l-pad is a great idea, I think.

Hey Bruce!

Well, I can answer that one. Of course, the 115L+ is a tiny, tiny little box, and the Celestion driver is voiced totally opposite of that PA subwoofer type 115 that we are all talking about.

So, in short.....

115L+.... very mid forward, and a tight, somewhat compressed low end and grindy upper mid that comes from (I think) a tightly voiced, full range driver being driven a bit beyond its excursion limits in a small box (from what I learned from Alexclaber... Alex, I hope I got that right). As a result, it's punchy, articulate and just loud as heck, but is much more upper bass oriented than 'shake the ashtrays'.

115/6.5.... that almost subwoofer type 115 with that high xmax (if again I have that term right), will go deep, deep, deep. Since it goes, deep, deep, deep, it won't go even into the lower upper mids, which is why it 'needs' that powerful mid driver.

So, 115L+, a massively tight punch machine that has that 'tight low end/aggressive upper mid grind, with a subtle tweeter on top to add some sparkle. I call it my 'baby AE410'.

115/6.5 (at least the execution I reviewed in this thread).... totally open, smooth, uncompressed deep low end, very even low mids and mid mids (fat), and a more 'bright' upper end (clean, even, paper cone sounding, no sizzle).

Another way to put it, the 115L+ could easily be used by Flea or even Marcus Miller with pretty good results IMO. The 115/6.5 would make Bob Glaub or Sting, or even Chuck Rainey, weep like a schoolgirl (sorry if I offended any schoolgirls:p... or Chuck Rainey)

Nice review and kudos to Don for an excellent addition to his line. He ought to sell quite a few of these. I like the size on this cab; easy to carry around and stack if needed. To get the full output, I'd bet the LDS 15/6.5 would sound great through a GK1001RBII which is rated 480 watts at 8 ohms and has a nice crisp punch with some growl to it.
