i've tinkered around throwing events for the past few years. my system is decent but i am moving from china to taiwan soon, so it's time to upgrade the system when i start anew. currently i have the following (all bought cheaply 2nd-hand here in china): 2x double 18" subs, roughtly 1000w a piece. 2x 15" mids, 400w a piece 2x 12" mids, 300w a piece. i like the balance of sound that this gives me, but i am ready for something more, with more bass. i have a friend here in china who can help me build whatever i want, pretty much (quality and durability is a concern). i'll either do that and ship it over from china, or invest in higher quality gear after my move. alternatively, i'm looking at the cerwin vega folded horns, either the 18s or 21s. not sure about the tops. so basically the question is a) custom build whatever i want in china or b) buy reliable gear for a price. i will be running weekly as well as monthly event series. big bass crunch is a must. budget is a concern. any suggestions?
