I had 4 of raul's 8" cans to do something with and I wanted to try pro audio but was hesistent because I have heard people say it is hard to balance the system correctly. I gave it a shot anyway and came up with a great pro audio system for cheap, so here is what I used.
4 8" raul cans
2 eminence HF drivers part number ASD:1001. These run 50 watts rms with frequency range from 2.5kHz to 20kHz.
2 eminence alpha 6 mid-bass drivers. These rms at 100 watts with a frequency range from 110hz to 8 kHz.
2 eminence 2 way crossovers model pxb2:3k5. The crossover frequency is 3.5kHz with 12dB/octave LP
and 18dB/octave HP. These are not cabinet ready, just the board.
2 Selenium HM11-25 Exponential horns.
4 mb quart rce 216 grills.
I installed the crossovers in the cans with the alpha 6's. That can has 2 sets of speaker terminals, one for the power in, the other for the tweeter out. The cans with the HF drivers have just the one set of terminals. I had to make a template to mount the horns correctly.
I ran the whole system in parallel to achieve a 4 ohm load to my amp. It is nice because you only have 1 wire to run up your tower. I am pushing the system with a fosgate 300s amp, it is 300 watts rms bridged at 4 ohms.
Once it was up and running I about crapped my pants. It was so loud and clear compared to any car audio I have ever heard. It was not harsh at all standing on the swim platform with the volume way up.
For all of you who are itching to get into pro audio, this system works and sounds great. The only downside is that you don't get the lower frequencies out very well. I got all of the parts from www.partsexpress.com
I can't wait to for my first ride to hear the speakers, I will let you know how that sounds!!
