My experience with mixing GK Neo cabs is that it yields a worst-of-both rather than a best-of-both outcome. I recommend two Neo 212s (or the 412). I think the Neo 115 has an "airy"quality that jist does not mesh well with the punch of the Neo 212 or Neo 410. If you plan to mix cabs, do yourself a favor and try the setup out before you buy. Of course, others will have differing opinions. YMMV.In the GK neo cab lineup. What would pair with a neo 115 iii? I have a pair of them I use with a mb500 and a 1001rb and it just seems to lack something. I am wondering if anyone has paired a 15 with a 212 cabinet to get some of the punch that is lacking currently. I have eq' the heck out of the rig and cannot find that stop your heart mid punch you in the face I am lookin for.
