[QUOTE="Peter Morris, post: 212301, member: 652"] Hi Fabio, You could still use the mid section but it’s complicated to build and tricky to EQ correctly, it’s just that the NDS1460n (and other 3" diaphragm drivers) will run out before the mids when pushed and may (???) sound a little strained when crossed that low, but I doubt if you will ever reach those levels with home theatre. FWIW I have used the NDS1460n in my double 10" design but I eventually changed to the BMS and lowered the crossover to 650Hz - this was an improvement. I have not heard the ND3ST but I believe it’s excellent, one of the best you can buy. I have heard the ND4015n but not the BE version. These are excellent drivers and I suspect with the larger diaphragm they may be capable (along with some of the new B&C and RCF 4' diaphragm drivers) of the performance needed. There is a big improvement in the sound quality of these new drivers compared to the older designs. To me the VHF is not quite as nice as the BMS. I suspect the ND3ST with a smaller diaphragm will be as nice, just lacking the low frequency output needed for this design. When I get some spare time I'm planning to post some information about cheaper options for the PM60/90 - I have had a lot of people asking about this including DSP settings for processors other than the lake.
