Anyone out there using this processor? I'm thinking of adding a pair midbass components to my system.At the moment I'm using a pair of QSD 213's (2-way components).I've got my Alpine HU set to "3-way" and I'm running all active.My question: If I go to 3-way components and use this processor can I still run all active and be able to use the sub control on the HU? Will I be able to high pass the tweets, band-pass the mids, band-pass the midbass, and low pass the sub? I want to run all active and still be able to adjust the subwoofer gain from the HU.At the moment I've got the 2-ways biamped. I'll add another amp so that I'll be able to triamp the 3-way components.Thanks, Martin

Yes the PXA-H701 will do exactly what you described. You can even have seperate Xover, Time Correction and EQ for two subs in that configuration.
To maintain subwoofer level control from the head-unit you will need to have an Alpine Ai-NET h/u.
Have a look on www.alpine-usa.com and go to Tech Center to download the owner's manual.

just a quick question on this processor. i have a iva-d310 and was also thinking about getting this processor. i'm running two sets of comps on the front, one in the kicks, the other set in the doors. they are two different brands, one is JL and the other is Diamond. my question is, since i'm running the JL's off the front channel of my 300/4 amp, and the diamonds off the rear channel, will the processor let me adjust the settings of each set of comp's seperately? Also, i'm currently running both sets of comp's wired stereo off the amp. Is this the correct way to do this? i have the rear fill just running off the head unit. sounds decent, but not sure if this is correct?

Yes-the H701 will let you adjust ea. set seperately. Are your components 2-way? If they are you'd want to get another 4 channel amp and biamp all components. In other words you want a dedicated channel off the amps for each tweet. and each mid. for the best SQ. You can run 'em the way you''ve described, but that will prohibit you from running active xovers with the H701. You'd need to continue to run the passive xovers that came with your components. Get it? Hope this helps. Martin P.S. It sounds to me like you're most interested in SQ. I would dump the rear speakers all together if it was me. You'll create a much better sound stage and your imaging will be better without the rear speakers dragging your stage rearward.

thanks for the reply. i'm kinda torn on what to do. you seem like you know what you are talking about and on another forum, a guy over(that seems to know what he's talking about) said i should not remove the rear speakers and remove one of my comps in the front? i don't know what to do? do you mind checking out the thread and giving me your feedback?

Here's my opinion if you're looking for SQ. You ARE ready to biamp! There's nothing to it once you start messin' around with it.I agree with the other guy that you should dump a set of your components up front. You should also DUMP THE REAR SPEAKERS!All the rear speakers do is pull the stage rearward(not good!).Run a single set of components up front and a good sub in the trunk. Dynamat the f__k out of your doors (if that's where the speakers are going)and trunk. Use lots of CLEAN power and again....BIAMP! Am I being clear on this point? OK then...food for thought- If you're running a single pair of 2-way components up front sealed kick panels will give you much better SQ than mounting them in the doors (even IF they're installed properly in the doors).I haven't been able to find a set of 2-ways with what I consider to be acceptable midbass. I've been running a pair of MBQ QSD 213's for the last year and a half biamped off a JL 300/4. Fantastic sounding speakers, but not good enough midbass. I'm in the process of moving them into sealed kick panels which will do a couple things... It will help my midbass considerably. It will also get my tweets closer to the mids and will help a lot with staging and imaging. I'm also adding a pair of Morel 6" (WR-6)midbass drivers in the doors powered by a JL 300/2. All active xovers.I'm conviced the only way to get top shelf SQ is 3-ways triamped with the tweets and mids in custom kicks and the midbass drivers mounted (CORRECTLY) in the doors. It's gonna run me $5-600 for the kicks and $4-500 for the Morels to be mounted correctly in my doors (labor only).Also adding the Alpine PXA-H701 processor and sat. radio.P.S. Did I mention...GO ACTIVE!! There are a lot of head units on the market that allow you to go active with just the head unit. My old Alpine 9813 gives me a HP for the tweets, a BP for the mids, and a LP for the sub. when set to the "3-way" mode. All controlable from the drivers' seat.P.P.S. This stuff sure is addictive!!!

After you yank the rear speakers leave the grills. The empty space where the speakers were works well as a pass thru for the sub. Martin P.S. Is the 500/1 enough power for the 12W7? I'm running a 10W7 with the 500/1 and it has always worked and sounded great, but I think I could have gone with the 1000/1 for my 10W7.Is your 12W7 in a sealed enclosure? JL Prowedge?

The 1000 is a lot better choice for the 12w7. We built a 2004 zo6 that has 2-10w7's and 1-1000/1 and 2 pr xr650 csi's. 1 pr of the tweets are mounted in the lower door panel with the 2 6" and the other tweets are in the pillars. The mid bass is awesome . It was day and night going from 1-6" in each door to 2 in each door. runing on a 450/4. I also resently put a set of the earthquake sws 8" in the doors of a 2001 dodge truck and it is unreal!!!! it also has xr525 set in kicks! Both cars have a butt load of Dynamat!
