1x15/2x8 carvin cab?

joshmmorrison · #1 02-09-2011, 03:33 PM

I found a Carvin bass cab with 1x15 and 2x8...any opinions about the sound of this kind of cab? I play rock/hard rock/contemporary worship. Just curious about any opinions about this?

Edit:
for running with a gk 700rb-ii

I saw an add in this month's Bass Player magazine. Fender has come out with a 1x12 and 2x8 set:

Not sure this helps you but it does show another vendor investing in a 2x8 bass cab.

If so, interesting...looks like it is of the RL series, but I never heard of it....

That's the Cyclops. I had one for awhile..decent amp, little on the heavy side but overall it was a good amp.

I think the speakers are a 4 ohm load for each, top and bottom.

nickelseye · #6 02-09-2011, 04:06 PM

Yeah that's what I was getting at, sorta. The speakers are wired seperately and I believe the 8's are a 4 ohm load and the 15 is a 4 ohm load. So, if I'm correct, either a 2 ohm stable amp or a stereo amp will be required.

joshmmorrison · #7 02-09-2011, 04:07 PM

ah gotcha. Thanks for the info, i didn't realize they were wired seperately. Won't work for what i'm needing. Thanks for the help!

You bet. The cab is designed for the RL600 head, which is a stereo amp which is capable of bi-amping or full range.

One thing I used to do was bridge the Carvin head into just the 15 for a clean signal, and use a seperate head for the 8's with a little grit. Worked great that way.

That sounds like it'd work pretty well! it looks like a pretty good cab

It really is a great cab and the 15 thumps! I liked it better with both amps. You can't go wrong if you have a second amp...with an a/b/y box.

The non-vertical 8" drivers are kinda spacehog wasted dispersion - one good 8" driver could have done the job much better, or two average drivers but set vertical... Still, the ol' Cyclops airhead cab would be great with a BX1200 or BX1500 slid in.

I like having the option of bi-amping, because I can use a small two channels amp for the highs, and a more powerful amp for the lows. But, I've only ever done it with PA gear; never tried it with a bass rig.

Edited to correct brain fart.

A lot of bass players have been wanking up the term bi-amping for a long time now, to the general confusion of many others. And now bi-wiring which is a scurrilous concept at best is getting misused in MI circles too? Why muddy the waters further? Read up:

What you have described above is bi-amping.

The R1015 models were paired with the R1000 head, the RL6815 were with the R600.

Actually, I believe the 2x8+tweet are an 8 ohm load, and the 15 is a 4 ohm load.

The cab actually sounds pretty good when biamped, although as Greenboy stated, the layout of the midrange drivers has some dispersion issues. I tend to gig with my Cyclops combo, even though its heavy and doesn't sound as good as my Demeter into my Acme's or my fEarful, because its loud and I don't really care if it gets messed up.

nickelseye · #15 02-09-2011, 06:35 PM

You're right Brendan, I was referring to the RL6815 and totally forgot about the R1015.

I believe you may be right about the ohm load too. Either way, bridging the amp is a no-no.

My bad. I know the difference. Cranial flatulence.

I was wondering about that because other than the term you had a clue ... my poots manifest themselves mainly in bad typing and bad moods ; }

Rip the mids out and put a 6nd410 in there.

Hey, greenboy, this issue could be addressed by turning the cab on its side, couldn't it? I ask because there's one available in my area as well, also sans amp, and I've been thinking about snatching it up to be run in this fashion.

greenboy · #20 02-10-2011, 09:50 AM

Hey barebones,

Yeah, that's possibly better out in the audience though it's awful close to the floor and reflections and blockage could make it not so, and it's kind of favoring the ears in your knees if you play anywhere close to your cab - rather than the ones in your head. And if stage space is sometimes at a premium that's not going to work out... I gigged a lot of years with an Ampeg 1832 Extreme (18", two 10", two 6") and it had the same problem (as do 410 cabs).

The best solution I found was to place 1"-thick open-cell foam behind the grill on just one side, so that it covered one of the 6" drivers and the 10" driver below it, with some cut space around the tweet. This cab was really bright so it didn't hurt to knock down the upper midrange output anyway. Maybe that'd work for you with 1" gray foam over one of the 8"s.
