    I currently have a GK400RB and a BL410 cab. I am wanting a 210 to add to it, and I don't really understand how the ohm thing works, so I wanted to ask if a GK 210BLX wpuld work not only with the other cab, but also if it would work alone with the head.

    Instead of "adding" a 210 to your Backline 410, you might be better off just replacing the Backline with a better, 4 ohm 4x10. Just a thought.

    rickenboogie does offer a good point that i second, upon retrospect.

    An 8 ohm cab plus an 8 ohm cab will give you 4 ohms.
    Just do not hook up an 8 ohm cab and a 16 ohm cab together.:cool:
     
  6. the backline series is actually very decent and I don't see any reason for the OP to get rid of it unless it's giving him problems.
     
  7. Why would that be bad? I know if your head can only handle a 4 ohm load then you can't add a 4 ohm and an 8 ohm cab but an 8 ohm cab and a 16 ohm cab (never seen a 16 ohm cab though) would still keep the load over 4 ohms. I believe it would bring the ohm load to 5.3333333333.......

    For a good result the 2x10 must have twice the impedance of the 4x10, whatever that may be.

    Would it be better to use something other than a 210, such as a 115?

    PS - I love my Backline cabs, it just starts to get muddy at higher levels.

    It gets muddy because the cab can't handle the power. Adding another cab won't really cure that problem, at high volume, the 410 will still get muddy. Not slamming the Backline cabs, they're "good for the money", but there are many better sounding cabs.
     
  11. That's probably because you're running out of headroom at that level. I'd say maybe get a 212 if your other cab is an 8 ohm cab. otherwise I'd try to get a 410 at 4 ohms to replace the one you have. There are better cabs out there than the one you have for the money you paid for that one. Look at Avatar cabs. I got an awesome 212 for right around $350 brand new. I liked the first one so much that I got a second one for my church rig.

    Also, I added a 210 to my Avatar 212 at church, both 8 ohm cabs, and I must say that it has plenty of power and sounds crystal clear at higher levels.

    I have found a Carvin R1000 head with a carvin 115 on my local craigslist for $400. is that a good deal? It has alot more power than the 400RB and I could definetly use it. Anybody know about the weight and sound of those things?
