Rig for super deep lows.

There's no need for the 18". The Acme can handle all the lows you need. It will give bigger AND tighter lows than the Carvin 1x18 and much better top end.

If anything I'd consider a second B4 if you really need a ton of volume and you have an amp with enough juice to really move some air.

A fEarful 15/15/6 is another option worth exploring.

I think the added 15 or 18 is more of a rounding out the attack because of 18 reacting a bit slower than an added low end thing.

Im not honestly sure about the fEarful cabs. Im reading and passing on what i can but id like an idea of price, build time, and the general idea behind them.
 
He's playing a Gibson EB-0 tuned in standard EADG

Roflcopter. I fail at read. ;)

No reason to go with an Acme at this rate unless you want that super even sound I guess. It's neat, just like the fEarful, but a lot heavier than the fEarful for no real major advantage for 4-string.

fEarfuls are a lot louder than Acmes in terms of sensitivity, so that's how I'd recommend going for 4-string, unless you just can't put that together.

Acme's 12s when they come out seem good too.
 
He always ventures above 100Hz, no matter what notes he's playing. Read the waterfall plots thread in the FAQ. Electric bass, and for that matter every musical instrument including the human voice, is all about harmonics, not fundamentals. A full fat low B needs flat response to 62 Hz, not 31 Hz. Probably not. Small speakers can go low, or they can go loud, but they can't do both. The characteristic response of large drivers in small boxes is a pronounced mid-bass hump. It's perceived as low, but the human ear is not the least bit accurate where it comes to correctly identifying how low a speaker actually goes; on average listener estimates run an octave lower than what's actually being heard.

One advantage is that this Carvin combo is a kickback, so it is shooting right at me. I am not very loud overall, but I can hear it nice and loud (over the drums). It does sound pretty deep, reminiscent of my sub in my home theater or the sound of the full system out front. It sounds deep.
 
right now he is using a Behringer 4x10 paper coned combo./QUOTE]

I'm assuming that cost is a concern given the current rig.

By the same token a quality 2x15 or even a single 15 is going to be a big improvement. As a plus 2x15 cabs seem to get a lot of turnover on craigslist for quite cheap. I'd have to say that even an old peavey 215 would destroy whatever output that beringer is delivering.

It may sound deep, but its low end is two octaves shy of what a good home theater sub will put out. And that's just as well, what a home theater sub produces is not useful for electric bass, nor will an electric bass cab work for HT.
 
Honestly, compared to what your bassist is using right now, most professional quality bass amp/cab set-ups in the 750-1200w range would be a HUGE improvement and probably make him very happy if eq'd correctly. I'd try this first before spending 4k on an esoteric "sub-like" rig.
 
it is? most bass cabs aren't good for anywhere near their rated power, even for fleeting power demands. you're lucky to get half a cab's rated power into most of them. power handling is one of the most bs specs out there.

While I'm not a mind-reader, I think he was talking about decently designed bass cabs that knowledgeable bassists on talkbass might recommend.

A lot of big brand cabinets are over-rated as to their specs, yes.

Continuous power at maximum output is an extreme exception to the rule of what most bass cabinets experience on a typical gig.
 
Wow, I like how the fearful is the answer to everything.

More seriously. I think he needs to get a different bass. I have never heard anything but mud from those EB0 basses. The only bassists I have seen that can make them sound not muddy either go for a trebly sound or swap the pickups out for actives.
Fender precisions are well known for thick low end.
Pair one of those up with a decent GK or Ampeg rig.
The Gk 4x12 with an 800RB or 700RB would be more than enough.
1500 watts? unnecessary. just because your current 450 watt head is lame doesnt mean a 1500 watt head wont be. Behringer? Well known to NOT have the most flattering tone.
OTOH if you go with the acme cabs I understand they are power hungry.

Sounds like mud is what he's after.
 
Based on the tone you're describing I'd still stick with my suggestion of a Carvin B1500 (I haven't tried the new B2000 and can't vouch for it) and to Acme Low B4's.

Actually, I'd go with ONE Acme B4 and see if that does it for him before going nuts with 1900 W of power.

I think the biggest issue is that he has a cheap cab that isn't capable of pumping out lots of lows.

The Carvin/Acme combo (and I know this from experience) is not grindy or clanky - just clean, muscular and huge. Tons of lows, but clear and powerful not mushy or indistinct.

I agree with this assessment. I would also be skeptical of Carvin's claims. The Carvin gear I've used has not been anywhere near the capability of Acme gear. Don't worry about the website not being changed in a few years. Andy is much more concerned with sound than he is with a flashy website that changed frequently. His cabinets really do what they claim. I used a B4 and a B2 for a long time before I decided to move back to the old school JBL sound, but I still have them and bring them out every now and then.

The Carvin amps are pretty good. The BRX cabs are very nice sounding - I like the tone of mine - but not anywhere near as deep as the numbers would suggest, so not a good option if you're looking for real big low end.

Maybe one of their big amps + a Fearful 1515/66?
