Review: Great DSP at a budget price - Purchased this because I wanted to retain my stock head unit but I was having some gain balance issues and couldn't get the sound stage centered like I was used to with aftermarket head units using time alignment. This is going to a 4ch amp powering my door and dash speakers on the front channel (factory wired as 4ohms) and a bridged 10in subwoofer After working with the time alignment I am a lot more satisfied with the imaging. Because of the way the speakers are wired I'm still dialing in the time alignment but I've got the band singing to me from the hood. I also had some balance issues with the head unit making my left side quite a bit louder than the right. Using the individual channel gain controls I've got that issue under control. The included crossover points are infinitely adjustable so my front speakers are better matched to what they can actually play. The preset EQs are a great start and with some more fine tuning I should have this dialed in. If you're amping a factory head unit I STRONGLY suggest buying this so you can overcome the factory tuned EQ curve and bass rolloff Very easy to connect inbetween my amp and head unit, just run a bridge wire over to your amp +/- and remote. If you're using speaker level inputs and your converter voltage is turned up you MAY have issues with the unit not powering off as I do. At this point it's a small draw and I probably need to tap a different line on my converter's remote wire but that isn't a fault of the unit, but it is something to watch out for as idk how many amps it's pulling. At the moment it may just be the blue led, time will tell.
Review: Low cost DSP for your vehicle. - Functions very well and very easy to program. Very nice to operate also and reliable.

### ⭐⭐⭐⭐⭐ STOP ! This is the DSP for you ! Did I mention it has an app ?
*by A***R on November 14, 2025*

I bought another brand of DSP. It was more than this Timpano, but it's still Not exorbitantly high. The thing about traditional DSPs is, that they're confusing. I wished that someone would make a ‘DSPs for idiots’ video, which is difficult for me to admit. But hey, you'll never get what you need if you're not honest with yourself. If only there was a way for me to sit in the driver's seat, adjust my DSP, and hear how each adjustment sounds. Hmmmm… wait a second. The Timpano DSP has an app ! I hooked up my new, $89 DSP, and as I dialed it in, I found the sweet spot for every adjustment ! AND, I could hear every adjustment exactly as it would sound, in the position that I'd be hearing my music every time I slipped behind the wheel ! I had a very small issue with the first Timpano DSP, but a new one arrived the next day, and all I had to do was sync it with my phone, and all of my settings were set. THIS is the DSP you want ! It makes your music, coming from your system, sound exactly as you like it. Did I mention it has an app ?
