Yes so far so good. Not much support on the product and not sure if there is a mobile app. No way to contact the seller. I am coming from a Rockford Fosgate 3Sixty.3 for reference. I got the dreaded Soild red light and nobody can repair it and I needed something quick and cheap so I did not have to go weeks with a radio. The Seventour is not as intuitive as the 3Sixty.3 but the 1st thing I notice is the floor noise is much lower. I did not change anything in my system just a DSP swap and not more hiss and random noise in my right rear speaker complete silence when volume is off. I just wish the remote was more compact and simplistic like the Rockford 3Sixty.3. It has been install for 3 days now and I am happy so fare. Will tune with a RTA in the next few weeks and see how it performs. Back set up with cross over point and time delay right now. Zero equalization right now and I hate to say it but sound better that my 3Sixty.3. I am using it as a pure DSP connected tobacco factory head unit with a RF Punch 1000x5D.I will post another review in a few weeks11/10/20232nd Review after having it install for more than a week. Originally I stated not much support for the product. I take that back. Eventhough they do not currently have a website, I have emailed several questions and the responded in less the 12 hours. During my time at SEMA 2023 I saw several other companies selling their DSP's for more and some for a lot more and quality was not as good as the Seventour P48E. This is one of the lowest price legitimate DSP's on the market and it is not is one those little plastic cases like some of the well know brands that offer similar or less features. If you are in market a DSP's get this one before the word gets out and the prices go up. I would not be surprised to see it being re-branded and sold under a different name for more money next year. I have had time to start find tuning my system and I still impressed with the sound quality, but the best thing is no noise added to the system.

Definitely couldn't get it to work horrible install my work paperwork

To have been looking for an affordable and decent DSP for a while and I came across this one it amazing, produce great quality sound with the ability to tune your system to exact frequencies with out additional equipment. It also come with some preset tuning which you can work from which is a plus.

High quality DSP for a budget build. App works great on my iPhone 13 Pro Max upgrade to a s25 now it’s not working.

No good doesn't work

It very simple to use and have 6 pre install tunes and you can set your own tunes and has a monitor to adjust if looking for something to get the job done and not spend a lot but worth every penny

Have done many DSP installs, mostly standalone DSP units with separate amps. This unit has the same interface and versatility as the much more expensive setups AND has a very good sounding multichannel class T amp integrated although lower power. If you have efficient drivers this with a sub amp will suite the audiophlie in you. I am amazed at the SQ for this price!

I am using this strictly as a line converter and DSP. For the price, this DSP has everything I am looking for in a DSP. I am running a 3 stage front with subwoofers. As a DIY person, this DSP works for me.
