I have a SVT-410HLF in transit to me right now. I'm thinking of adding another cabinet to my setup later on. What would make a good pairing with the 410? I want something portable so i was thinking about the SVT-15e but since its 8ohm and only able to take 400watts, it may not make a good pair. The power amp I'll be using is a RMX 1850HD. Can I push uneven loads like that? What are your thoughts? BTW, I just got my first bass setup. SVP-Pro, SVT-410HLF, QSC RMX 1850HD, and a Lakland 55-01. All of which are still in transit!
