Solid dsp. No distortion noticed yet, no popping on start up. Definitely a lot of bang for your buck with this little guy, 6 in 10 out is great. With the app it's simple to configure and pretty straight forward. Hardware wise looks solid but the 12v,S,ground terminal could be a little more solid. "Update: seems cheap due to it being removable, didnt know this at the time" Its nice the bluetooth antenna is removable as I had a extension flat antenna from an old headunit that I ran to the front of my cab, though I probably didn't need to. The app is fine. Works best in landscape but will work in portrait mode, but kinda crams everything together. Only reason I bring it up is my andriod headunit is in portrait mode and that's where I config the app. But worse comes to worse I can use my phone. Toslink in would be a great addition to the next version but rca is fine. A actual manual would be nice The reported voltage is about 1 volt lower than real voltage. Thank you B2, solid DSP you guys have here. Update: Definitely some boom noise randomly when it turns on. Pop. I hate the apps eq setup. Hard to select the frequency with out altering it. Use a s-pen or bring it as all the way down then back up to the level you want. Wish the channel eq could be copied to another channel like the crossover settings. Still happy with the dsp after a few months.

I returned the expert px2 and swapped to this one. The expert px2 had a white noise and pop when turning off. This unit is perfect, no issues regarding noise or pop. You will have to plan for some time to familiarize yourself with this dsp. The bluetooth is great as you can also stream music through this. I'd watch some videos, so your ready. I don't think you can beat this dsp for the money. Not sure of any others that also stream music close to this price It takes some tinkering and patience but it's well worth it. I'm very happy with this. I'm using my phone as the head unit for a classic car setup and this dsp has great gain control to get you where you need to be. I'm using the bluetooth and or a usbc to rca with the dac in the cord. Everything works perfect.

First off - this thing does do what it advertises - I'll give it that. I used this to take two channels of output from my factory radio, tri-amp my front stage w/o using the passive crossovers, and feed my subwoofer amp. After figuring out how the app worked - this was simple. I was able to setup my crossovers, channel mixing and time delay without issue. The app though is an exercise in frustration. It constantly disconnects without telling you. It will often freeze after entering the password (which has to be done EVERY time). The app completely ruins the experience here. It worked better with my Pixel 9, but I could not get it to connect ever to a newer Samsung 10" tablet. I don't have iOS devices to test. Noise level - I had zero noise on my bench, but I have an audible hiss at all times from my highs in-car no matter the source. This could be my car, it's a PHEV so may be interference.... It's very minor, and I'm sensitive, so not blaming the DSP, but I do suspect it (previous 5 channel amp with no DSP did not add hiss).... Quality wise - the box feels built well, it's super tiny and lightweight. I do wish the power/gnd/rem connector was "something else". It's a bit wonky for what feels to be an otherwise decent product. I'd love to see an updated firmware/app that will deal with the connectivity issues and this will easily make this a 5 star item. Overall in terms of bang for the buck - it's definitely got that nailed.

Build quality is good processing is great the application is ok. The app takes a bit to get used to but once you figure it out it's pretty good. The unit is great, does what it's supposed to and store multiple settings locally. I love being able to change my time with just selecting a different saved tune. When I'm really pushing my system it gets a bit warm but have had no issues so far. For the price I think it would be hard to beat. Highly recommend if you need to tune your aftermarket system or want to upgrade a stock head unit to add anything you want.

This 6 input in and 10 inputs out is amazing and not just for the price. If I upgrade 4 channel amp and add more speakers I’m basically set with this DSP. The app is easy to use but does require for you to enter password every time you connect it. When getting out of the app and returning to the app. It creates white bars on the sides of the app and you can’t see some of the menus on IOS phones. Setting EQ for individual channels, Gain, Delay and crossovers is super easy. Comes with no instructions but just watch some YouTube videos and you’ll see how easy it is. I feel like everyone complaining is just tech challenged, phone challenged or have sausage fingers. There is nothing complicated about this user interface. That there are better options is not the point. Because they also cost a lot more. So for this price point if feels like it’s a steal as long as your not smartphone challenged.

UPDATE & PSA: if your Sixten starts randomly muting itself for no apparent reason when driving or even starting the car, download the firmware update from B2audiousa - it was hard to find but fixed the problem immediately. Also FYI the sixten android app is old, use the B2audio DSP app it is newer and doesn't crash!!! So far I really like this DSP but it has some easily fixable quirks that annoy me, not enough that I would consider another DSP in this price point however. YOU NEED TO KNOW WHAT YOU ARE DOING, there are no presets or magic profiles that will get you started - this is a tool for audio tuning and you need to understand phase, EQ, crossovers and how they behave and especially time alignment. Tip you can use grok or other AI tools to calculate time alignment for your car speaker positions as a starting point. IF YOU KNOW WHAT YOU ARE DOING you can make things sound amazing. The bad: The Channel EQs are very fiddly and for some reason you cannot simply copy one channel to another you must manually configure each channel which is very time consuming and inprecise with the controls provided. YOU can dial things in very incrementally if you key in the frequency, Q and DB+/- on a band, then swap to the 2nd channel and make the same adjustment to the same band it helps a bit but this could be ALOT better. Make sure you leave some headroom on channel Gain if you are adding DB to EQ bands to avoid distortion, or cut instead. The channel EQs have about 10 bands more than they really would ever need making them very cluttered. I would suggest allowing us to specify how many bands we want to simplify this and allow copying channels like you can with crossover settings. The app will not remember the connection for the DSP and you must manually connect to it each time you turn the car on to make adjustments and it can often drop connection for no apparent reason.....it wasn't seriously disruptive to tuning process but was annoying and seemingly this could easily be fixed by saving the connection profile in the app and having it connect automatically - its mind boggling why the developers haven't implemented such a simple concept. Time alignment when set with MS sometimes rounds up or down 1/100th of a MS for no apparent reason when storing profile but its not a significant hinderance. If you are planning to connect to this via Bluetooth I was only able to use SBC when testing and it did not seem to support aptx or LDAC standards etc.... which is disappointing but I am using RCAs and I didn't fiddle with it much. With some software improvements this could be a perfect DSP the hardware seems reasonably solid. The power connections are a little dinky but work well enough.
