I plan to import the driver and/or sub kit with Amp depending on what I buy. Current thoughts are buying the Rythmik 1510 driver and 600W amp and building a FV15HP equivalent or buying 2 SI18's and building either 2 sealed boxes (the simplest) or 2 Marty Cubes or MartySubs (which don't look to difficult). SI18's would be driven by an iNuke3000 or IPR3000 which are roughly the same price in South Africa.
My opinion is that the FV15HP clone would be more of a known quantity (Brian sent me the enclosure drawings) however dual SI18's (sealed) would give me the benefit of multiple sub smoothing and similar performance to a single FV15HP (using Data-Bass as a reference)
I have a dedicated theatre room so enclosure size isnt really a problem.
Opinions, advice welcome
I highly recommend your Rythmik solution. I built two of the DS1510 and PEQ600XLR3 amps and could not be happier. I am an experienced wood worker so it was very easy, but a layman could also do it without issue you just want to take your time. I built mine using Brians plans with a slight modification which is I added another layer of 3/4 MDF all around the cabinet with the second layer joints overlapping the first layer joints (helps with keeping it airtight) and finishing it with a extremly high figured Cherry 2 ply PSA veener and 4 coats of Wipe on Polyeurathane. I did both for just under 1800.00 were a coparible off the shelf sub of the same quality could easily cost 1200.00 not including shipping. there are pictures in my profile if you want an idea of how big they turn out or just to give you an idea of what they look like finished.
