Actually, I already bought the Helix DSP.3. Looking forward to getting it installed in-car relatively soon. I like messing with stuff like this "on the bench" for a while to get familiar with it before actually installing it in-car - just makes learning the ins-and-outs of these products a lot easier than trying to learn them while sitting in a car.Yeah helix/brax products are the best DSP right now. I have the PSIX dsp mk2 in my build, and love it. You definitely want to upgrade the speakers to take advantage of the processing power. I use hybrid Audio Unity U69 6x9 woofers in the doors. Which they are 2 ohm drivers, I have 230w going to each driver. Let me know when your ready to pickup the dsp.3
I actually bought the Helix DSP.3 from an out-of-country reseller, just because it was significantly cheaper to do it that way (and at the time, I wasn't sure where to buy in the US). I mean I only paid $535 + $32 "tax" from this reseller (free shipping) and it arrived in about 8 days or so from Poland. My understanding is that I would have paid at least $700 from a US reseller, so that is a significant-enough savings (~$135) to warrant the small "risk" of buying from an out-of-country reseller (risk related to shipping back if it arrived DOA or requires warranty service within the warranty period). I really dislike the fact that Helix products are not sold online and that there is no MSRP listed anywhere for their products. Just makes it easy for resellers to overcharge for products, since there is no easy way to know what an item should actually cost. It seems that this is just the way things are done with these higher-end car audio products - and it's unfortunate IMO. I just want to be able to go online, do some comparison shopping and click a few buttons to buy the damn thing. In this day and age, this "brick and mortar only" sales model is just outdated. For us DIY'ers, it really sucks. I don't want or need a brick-and-mortar store to be the "middle man". I don't want or need any installation-related or consultation-related services, so to me, there is really no value added by this sales method - it just increases cost and makes it harder for me to buy their products.
I'm still not fully on-board with these crazy-expensive car speakers. $400+ for a pair of 6x9 midbass speaker just seems a little much (and that is for the 'low cost" higher end speakers!). To me, with these advanced DSP systems, you can really fine tune the speaker output so much that I'm not yet convinced that such crazy-expensive speakers are really needed. Not to mention that most of the more expensive speakers require custom installations - not simple "drop-in" speaker replacements. I really don't want to have to modify my a-pillars to mount 4" mid speakers and tweeters right in the A-pillar, directly facing the driver - it really looks horrible to boot (IMO). I'm just not that far down the car-audio rabbit hole yet.
Like I said, I have really been impressed with these Kenwood Excelon speakers (first experience with Kenwood speakers).
