Low Down Sound 15/6.5 Cab

#461
I added casters last night. The cab is very stable when moving it around by itself, but when I put the B1500 on it becomes front heavy and if you don't orientate the wheels before pushing it from back to front it could tip over. You have to make sure you're careful when pushing form front to back on carpet as is.

I'm not diggin this so I think I'm going to cheat the caster slide mounts all the way to the front of the cab for more stability. None of the screws where long enough to go all the way through the cab. It wouldn't be an issue with a BX500.

With the amount of low end my cab has I doubt I have a 3015 but I'll check.

Yeah, but that B1500 weighs almost as much as the cab. ;) My cab is shorter and wider, so I don't think I'll have such issues. Plus, Don was thoughtful enough to install the handles a bit closer to the front of the cab so it would balance better when picking it up when there's a head in the rack.

It's hear, I stuck a 3015LF in it and Don's sending me a new one, same deal as BP and DG :)

It sounds really great - having an issue with my amplifier's chassis rattling though so going to be a bit on recordings.

It's not quite as loud as the 3080, of course, but the mids/trebles sound a LOT better (despite the horn in the 3080). The low end feels a lot more defined, too, I presume because of the much larger internal space per driver. Pretty happy with the lower xover trimming the nasty mids out of the 3015LF for sure.

I think this is going to suit my needs perfectly.

Yeah the rack is about 40lbs and everything is loaded at the very front, the back 3rd is just air. That rack's literally 80/20 front/back on the weight, the cab is about 55/45 weight-wise.

I wonder if there's a way to lock the swivel casters in the position pictured? I think it's actually time to address the rack portion of my rig ie smaller rack, lose the compressor and rack light.

My old Carvin BRX212 had no problem with these casters but it was 24"w x 20"d @ 83 lbs.

I actually didn't even fire up the 3015, didn't want to cause any issues returning it for Don. Turns out that's not an issue, but I'm not screwing another driver in :)

So far, I'd say it's ridiculously even. Studio monitor-esque from B to G. Since I'd already broken in the woofer I cranked it up a bit and everything sounded amazing except when I really dug into the low B - seems like the grill might be a bit close to the speaker surround as I got a couple quacks. I'd assume that's due to the difference between the LF and the 3015 in terms of displacement. I'll be reviewing my EQ and see if it's something I can fix by cutting a little sub-bass without giving up my sound too much.

I'd be interested to hear if anyone else has that issue with the LF though.

Edit: Also, I *cannot* wait to try this cab out once I replace the foam in my pickups and can get them set so that the treble strings aren't so quiet (an issue with my setup no the cab at all). They sounded so amazing as is, it'd be nice to hear them up closer in volume with the bass strings.

^ RS my cab is completely rattle free with the LF. I'm pleasantly surprised.

My CD player skips at med/low volume now, and the cd player is slightly behind the cab. No cab has ever done that. My snare and kick have made it skip.

4-string or 5-string?

Mine literally only rattles on the low B at super high volume. I can abuse the E-string and get nothing and the same with C#/D - haven't tried C much but I'd expect it's the quality of the open string + the B being super low.

Also, the grill could be a little bent from being replaced or manhandled. The Fedex guy practically chucked it on my porch :P

Couple other notes:
1) The finish is amazing. The coating Don uses is really awesome. Smoother to the touch that DRB's bedliner stuff and feels quite tough. Looks great too.

2) The weight!! With the spring handles I got I can't one-hand it, but it sure is light enough. I carried it very easily. Feels like about 50lbs, maybe a little less.

It might well be the travel of the 3015 surround. I gig-tested an alpha prototype of Acme's upcoming neo 12 (without a mid-driver or a horn/tweeter) this weekend and Andy had to remove the grill before he gave it to me. The surround, due to its increased xmax, was hitting the grill when played.

5 string Dingwall


RS did you post a pic of your cab already?

Holy Moly! So that cab had the regular 115 in it. Interesting, since it was so full and deep and smooth with the regular non LF in it. I'll be interested to hear your take on the difference in the two drivers.

Interesting, so first cab you tried out, which now belongs to Chef, had the LF in it because it didn't have the ribs on the speaker. And the second cab you tried out, which belogns to rpsands, didn't have the LF in it and still sounded deep. I will be interested to hear someone's take on the difference in sound.

All I know is that they both sounded fantastic, and both had a similar low end. I did hear the 'Greenboy' design as being a little 'bigger sounding' and a little 'smoother' in the transition from the lows to the mids. Since they were both different in a number of ways (box size, port design, crossover, and maybe driver), I have no way of knowing what is causing what regarding the subtle differences in tone between these two very nice cabs.

I again know absolutely nothing about the internal components of cabs (i.e., different driver numbers, etc.), and can only comment on what I hear.

Finally, as I mentioned in my original review, I was powering both cabs with relatively low powered micro heads (about 300 watts into 8ohms) in a very small room, so any difference in the deepest low end at high volumes with high power would have been beyond my test.

The great news is, both these cabs, to me, sounded great, and Chef seems to be digging the original LDS execution that kicked off this thread:bassist:

So will I, Ryan. It sounds like another instance in which an A/B listening comparison would provide useful information to compare to the specs.

I just re-read Chef's review and I found this little bit:

Chef said:
The 3015LF moves some air. More than my 3015 loaded Mesa Diesels????...????
Meh...mebbee, but it doesn't feel any different, I think the 3015LF "ups the cabs ability to take a Whipping and Keep On Ticking."

The lowest "usable frequency" for both cabs is 40 Hz according to Eminence.

A few Carvin LS1503 users who swapped in 3015LFs had that problem IIRC, and I've observed it myself when using thinner round grill screens. You need a fair amount of room to the screen, and a thick, well-mounted screen. Since you just did a driver swap, maybe...???:confused:

Ah, I wondered why Don didn't have the gasket on my 15" right against the grill like most manufacturers. Perhaps this is why mine is rattle free, that and all the extra bracing on the front of the cab.
 
#480
Mine is actually a good bit off the gasket, maybe 1/4" from it - but I can hear it slapping against it. I unchecked the ultra-low (+6db @ 40hz ) and I can only do it if I really dig in now, instead of minor digging. I really like the ultralow though :P Makes it sound super fat.

I checked it out and the C won't do it unless I maul the string - so it's a pretty minor issue all in all. I don't really pound the B that much.

I'm gonna see what Don has to say - maybe if I use some deeper spacers right around the speaker cone it'll push the grill far enough away that it doesn't do it. I might also have him rig me up a fabric grill if that winds up not working. I dunno.

Just want to reiterate what a minor issue it is and probably not anything Don did - the grill looks just a little banged up. If it got dented in the wrong spot (which I can't tell) it could easily cause that. It seems to only be hitting on a very particular spot so I think that might be it.

More comments to follow :)
