decisions

I have been going over in my head how I want everything wired and struggling with only one area unsure what to do. I will be running the eq215ix to full capacity to split the signal to the low(Ti9s) and hights(Elite 5 and 1 componants), as well a bandpass attenuated signal from the aux out for the rear speakers(also 5 and 1 componants). I will be using the roadster to play all the componants and and the subs, and the mq430 for the Ti9s. I know the 9s are recomended to play from 40-150 hz but I am not sure how I want to cross over the 9's in relation to the rsdc's, and how to do it. I have a Ax204a that I could use half of if I can find an Rnet that goes low enough for a high pass cross over, or if I should use some F-mods or something? I am not real big on having them both play the same range of freqs to worry about cancellations, but would also like to get the most out of the system for mainly sq tasts and only the occasional bass head throw backs we all have. I also have a bass cube to put in somewhere but I think I would like to listen to it first and see if one set needs it more then the other. I am building the enclosure for the 9's as big as the space will allow but I would not be suprised if they need some eq'ing, although they will be eq'd through the 215 soo....

Too many choices been bouncing around my head, what would you do?

If you are running the bandpass section of the EQ215ix out to rears, you don't need to use the passive crossovers, and the tweeters. The bandpass filter will be mostly or totally (don't remember the crossover point of the EQ215ix) filtering out the tweeter, so it would just "be there" doing nothing. If you run the Ti5 mid directly from an amp which is fed by the bandpass output of the EQ, you are going to get the best performance out of that mid.

You probably want the EQ to be able to EQ the whole system, so you have to put it first and then have an additional crossover after it. If I am understanding you correctly, you could run the AX204a from the lowpass output of the EQ, and then it would high pass to the Ti9s and low pass to your subs.

One other possibility is to use the Roadster only. Run the front of the Roadster to the front components, and the rear mids in parallel. To cut down on the mids, use inline resistors on them. If they are playing a bit too high, then lowpass them with a coil as well. Use the rear outputs of the Roadster on the Ti9s, and the sub section on the sub. I am sure by doing this you can use both the EQ215ix and the internal crossovers of the amp to accomplish your goals.

I was originally going to go with just the roadster until I realized I could do the bandpass attenuated option out of the EQ, and came across the mq430 for a good deal. I liked that idea as I was going to use the low pass out of the EQ, combined with the adjustable sub-sonic/hp filter of the roadster to get the bandpass I needed (50-150hz) that I needed for the 9s. It just seems like the additional power that the mq has would be better suited to be used on the 9s rather then the rear speakers.
