Well i can chime hear about Peavey which i used for 15 years before changing to Mackie. The parts are easy to come buy, woofer replacement is easy. So if you blow a woofer you can eaxy replace it. I use to keep 2 basket replacement on hand just in case if one gets blown. Crossovers can also be replaced. The only thing is the weight of the subs, they are heavy. Most subs are heavy because of the cab and the magnet in the speaker. JBL are a good speaker, but parts are expensive. Gemini is ok but you be replacing parts sooner on them. Good luck with your upgrade.
