G'day,
I've spent much of the past few months trawling through endless build threads of you kind folks. It's time for me to ask a few questions and get designing and building! In a past life I did a bunch of live sound, purely as an operator. Now I've decided to get back into it in a small way, and in the interim I've acquired some furniture making skills. At this stage I have a very basic/small FOH setup, and want to build some stage monitors. However, I probably need to work backwards from a future FOH build, as I'd like the front cabinets & monitors to match to at least some extent.
So, here are some thoughts and things I've gleaned.. I'd love to have any responses that anyone would care to give.
- For mid/high FOH boxes, I'm hoping to plan for something that will be as loud and sound as good as possible. The only caveat is that it must be able to be moved by one person.
- I'm fascinated by Peter Morris's PM90 boxes, but owning megabucks processing is not on the cards at this stage, so that probably counts these boxes out?
- The main concepts I've been looking at and modeling in WinISD are based on either a 12 or 14" coaxial such as a B&C 14CXN88, or a 12 & horn such as Beyma 12MC700Nd & appropriate compression driver.
- The consensus I've noted is that multiple cabinets = phase problems = bad. Is that right? I'm not considering line arrays, so is it correct to be looking at the most powerful single cabinet I can?
- In the case of the Beyma 12MC700Nd, that claims a sensitivity of 100dB (which seems somewhat reasonable from their graph) and the AES power rating is 700W. I believe this equates to a calculated peak of 128dB, not that this is what WinISD shows in my modeling. Is that a decent place to start for a small PA?
Thanks in advance for your thoughts.
