You need think of any system you build as how much SPL you need for the whole frequency range, since the HF driver is much more sensitive, you don't need as much power to get the same SPL as the LF section of the speaker.

Regarding your comments about more power needed for LF than HF, in simple terms, what is the ratio or percentage difference generally between LF and HF power needed to get a balanced system - just an approximation of course ....?????

I use the DRPA. At first , I was a bit intimidated by it but now I love it. My SRX speaker tunings are built in and the amps I had set up manually. SRX715 bi-amped tops with bridged Crown XTI 4002 mids and Carvin HT760 horns AND SRX718 subs with a XLS2000 bridged per side. I used gain structure to get all my meters where I want them. When you to take the time to answer my questions Dakos, I learn a little more that I knew before. I love the science behind sound.......it fascinates me. There are very differing opinions expressed by some knowledgeable (and not so knowledeable) people on different forums so I am always aware that personal opinion can muddy the facts and I need to discern what I take from what I read, I find your explanations well written, clear, easy to understand and I appreciate that.
I just thought of one more thing regarding the subs. I originally purchased MRX518's early this year which sounded great with the srx715's. However, I got tempted by the low price on the discontinued SRX718 and bought 2. I played them side by side and I like the SRX's more.. IMy plan was to sell the MRX's. I never even used them live - they never left the house. It took me a while to build the system and the band broke up just as I started to piece things together. However, I have had many inquiries for the MRX's but all have been no shows. Now I am wondering if I can use them rather than have them sit around. Of course I would need another amp but would a mrx518 and srx718 per side make things better or worse??? I have heard that coupling different speakers isn't always a good thing. I thought I could use one set of subs through aux for extra sub boost when necessary - so in effect outside of the 3 way system. Good or bad??

Thank you for the kind words

Thank you again....... I'll give the MRX's a try along with the SRX's !!

Set up PA as usual, three way except I'll steal one of the Crown XLS2000's from the set-up. SRX718's + SRX715's bi-amped.
I'll use one of my XLS2000's to power the SRX718's in bridge mode and the other to power the MRX's in stereo (well, 2 channels)
As I do not want to purchase another amp yet in case the subs clash, I'll just use what I have for now, I can get an amp later. It is a small place so I can keepthe levels low.
Then, I take an output from the aux at the desk into the XLS2000 and l'll activate low pass on the amp to around 80hz ish and also 'Y' feature.......Am I right??? I'm keeping the subs separately fed so the MRX's don't get the same frequencies from the DRPA as the SRX's do.
