New to TB and pairing up cabs as well. I am looking for options to pair with my GK CX410, this is a great cab, but I am looking to push more air. I was looking to see if I should pair up with another CX410, which is the most expensive route; or should I consider just adding a CX115 or possibly the CX210. I am running my 410 with a MB500 and it is an 8ohm cab. Thanks for taking a look at my post and any input is appreciated.
