Hi All, I originally wanted to do a 4345 Clone but I decided to try a 4344MKII version first but in a 3 way. I have the 2245's for a 4345 but I will try with the MCM 55-2963's 15" which are supposed to be very close in sound to a JBL 15". I have two pairs of JBL 2123H's and the Beyma TPL-150 is on their way. I have created a xover for these drivers using Xover Pro software and it looks (Graphs) really nice so far and all drivers seem to match up very well. For now I will be using the 15" Knock Down cabinets from Parts Express that I got last week. This should give me a good feel for what this combo of speakers can do. I will be making an enclosure for the 10" to isolate the 10" from the 15" woofers like in the 4344 and will set the Beyma 150 on top of the cab. I ordered the TPL-150 without the horn so I can get a wider dispersion (120 degrees horizontal) than with the horn (80 degrees). Hope this will work out.

I still need to get the 2245H's reformed. Once I get those done I may take a stab at the 4345. But for now I will just stay with the 3 way 15" version.

Any feedback or info is appreciated.
