I'm getting a pair of dual opposed cabs made locally, net volume ~5.25cf. I would have gone dual 18's but am restricted in width to 18" max, as these are going to be used as tables beside my seating. An inch wider and these can't happen.
I have modeled many drivers, but being in Canada I am somewhat limited to driver selection. I have no issues ordering from Parts express, and have done so in the past. From what I have found, that gives me the dayton's, LMS, and Mach 5's as top contenders.
As much as I want to just get 4 x LMS-r's and be done with it, the 'fun budget' will run out after buying 2. I have (seriously) thought about getting 2 now, and wait for 2 more, but am not sure when that may be. I also don't really care for the gobs of power I'll need - was hoping for a single ep4000, inuke, or similar amp to provide power for all 4 drivers. I'm guessing a fp14000 clone would be needed for adequate headroom with these.
That said, I can do 4 dayton titanic mkIII's or 4 Mach 5 IXL 15.2.2 within the existing budget. Completely finishing this project in one go with a single amp is quite enticing.
Using a single ep4000, wiring both cabs together to create a single 4ohm load, I think the titanic option seems best in winisd. They should just nudge 20mm xmax at less than 5hz with ~500w/driver in 5.25cf shared.
Am I making a mistake with the dayton titanic? I don't see many builds with this driver when searching.
*I should note that I currently have a pair of sealed LMS 5400 Ultra's and a BFD for eq, so I am not depending solely on these cabs for bass. My wife told me to take care of some side tables, so I figured why waste the space with silly furniture when I can add some headroom.
