Well I would want to build the complete Sub within $750 range.. ( I have bit wood working skills and necessary tools )There's not a massive difference in terms off spl between the Q15 and the LMS driver. The LMS driver is probably the better driver in terms off spec and how it performs overall. The Q15 driver would only need a 2 cu ft box where as the LMS would need a 3-4 cu ft box. The other option would be a Q18 which would need a 6 cu ft box but would have more spl than the pair off them. The LMS is based on 1500 watts input power and the FI's are 2000 watts.
The other option would be the Mach Audio UXL-18 which only needs a 3 cu ft box.
Does the $500 for the driver and amp or driver alone.
The best performance I can find in that price range is the T.C. Sounds LMS-R 15 for $433 shipped.
4 cu.ft., 1500 watts, Xmax at 12 hz.
