I'd like to find a DSP that I can input BiQuad parameters directly, and/or one that can use the EQ output of REW (Room EQ Wizard) directly. If it has long configurable FIR filters, that would be ideal.

I'm kind of doubtful that car audio DSPs would offer direct IIR/FIR inputs, so if nothing with those capabilities are available, what's the most configurable DSP?

Right now I'm considering the Helix Pro 8 or Mosconi 6to8, leaning toward the Pro. I found a comparison chart from a few years back:

But there are probably some errors. e.g. the Helix webpage indicates it has a 96ksps rate rather than a 192ksps....

TIA

I would head over to CarAudio dot com and give them a shout, they're really helpful over there, especially post like this since you seem to have some research done already.

I haven't used a DSP yet, so I can't give much info beside playing with it at the stores. But if you need a Answer from those carts. The Mosconi seems like a better bet since it has more specs info.

Helix dsp pro is the most configurable car audio unit out there, and yes it is only capable up to 96khz.

Mini-dsp has a few that can import correction curves from rew.

There is another pre-dsp box that comes with its own measurement equipment and compensates with FIR filters before it gets to the dsp, then you correct time alignment and crossovers with the dsp. It has been highly reviewed by everyone that has used it. I'll try to get the name later.

I LOVE my pp82dsp and the software, once you get used to it.

I took a quick look over there, but didn't see anything already posted. I loathe signing up for new forums (they just wind up sinking so much time). It probably is the right forum for that, I just have to overcome my own resistance.



The Helix Pro is still in the lead for me. It didn't look like the min-DSPs had much in the way of processing power, and I thought they were more home than car. I am interested in the latter one you mention, using FIRs in that way is most of what I want to do with them, though there's some danger of winding up with a really peaky response due to room modes changing with small position changes. Also, I'd think FIRing as the last stage (and individually for each speaker) would be the best sequence, but it still sounds promising.



It looks like the pp82dsp has a 48ksps DSP. I'd like to get processing that samples at a minimum of 96k to minimize attenuation due to sampling. I've also already got a multi-channel amp. If I had known about it earlier, it probably would have been a good option. Still it's a good sign for Helix/Audiotec-Fischer.

I guess I don't have enough posts yet to thank people, but thank you all!

Nice DSP ;)

I'm about to have a Mosconi 6to8 install in a week with all mosconi amps, subs and their 3 way Zero Pro front stage. I'll post up a thread when it's done.

Helix put out a revised DSP & Amp combo this month (Helix P Six DSP Mk2), that has 96k sampling rate 6 amplified channels and 2 line outs. I wish it had 4 line outs, but for what I want it should work well enough. I've spent a couple of weeks trying to find somewhere to buy it in the US with no luck, so I ordered it off a German website. If it makes it through shipping & customs I'll post the details.



Where are you planning to mount the mids & tweets?
