[QUOTE="Peter Morris, post: 148519, member: 652"] Re: 60 Degree DIY Mid Hi FWIW here are a couple of SIMs comparing the low section power response. The SPL response is more, particularly at the higher frequencies once you allow for directivity. These are of course only my best guess and are just computer simulations. The DIY is using the B&C 12" @ 400 watts each . The M4 is at 400 watts and the 960 is using 2 x 10" drivers @300 watts per driver. The 960 will make the same SPL as the DIY above 200Hz when you allow for the directivity etc. but is 3 dB less around 100Hz. The trick with M4 is to use all of the program rating of 800 watts.
