Alpine DSP PXE-850S outstanding quality audio

Crutchfield customer from Anaheim, CA on 1/24/2021

Verified employee purchase (What's this?)

First of all, I bought this DSP because of it versatility. Once it has been hooked up to your sound system, you can either use a computer or a portable device such an iPad or iPhone with the PXE-DSP app and configure and adjust the 6 inputs (Front, Rear and sub) from the after market head unit and each of the 12 outputs. If all your RCA are connected on the right input and output, the time alignment will work at it best and do not forget to measure the distance between the driver and each speaker to configure Time Alignment . If you have Mid Range and Tweeters on your pillars make sure to point them to the ceiling of your car 1 foot apart from the windshield. It's amazing having 31 bands of parametric equalizer to adjust each output. Basically you just need to adjust the bands within the frequency as you configured the HPF, LPF for each Output. This Alpine DSP without a doubt is probably one of the best DSP's in the market. Another awesome acquisition from Crutchfield. Also if you are looking to improve the quality of the audio on your car modern factory system, this is your best choice.

Pros: Rotatory knob allows you to select one of the 6 presets on the fly or you can use you smart phone.

Cons:

Alpine PXE-0850S

Crutchfield customer from Loganville, GA on 6/14/2020

Verified customer (What's this?)
Verified employee purchase (What's this?)

So far everything is working. Tons of features but I can't help but feel it's missing a few things. First I don't understand why my Alipne head unit uses dual rca sub outputs, the dsp has dual inputs and the amps have dual rca inputs yet dsp only designate one channel for sub output. This forces you to use either an adapter after dsp or designate another output as subwoofer output but internally none will link with subwoofer output. Also the until feels a little delicate and not sturdy. Wish the input and outputs were tiffany style. Plus the volume control will not work if bluetooth is connected or so I far I can't find a way to get it to. So their claim to use bluetooth dongle to stream from phone would mean not being able to use volume knob as well. Phone app works but for some adjustments you will need laptop.

Pros: Several channels clean output

Cons: Phone app is weak fit and finish feels a little cheap.

Great EQ subpar overall sound

i bought this to run my g60s,gs60, and gs25 active, it just doesnt sound as good as youd expect it to, at this price this is steep youd be better off getting a d4.800 or just getting a helix and running multiple amps bluetooth codec is aac not aptx not something youd expect at this pricepoint either youd be better off getting a headunit with a 13 band eq and crossover and time alignment rather than this save your money get better speakers and get better sound "Sound quality was very good although I bet a standalone amp would provide a better overall sound (can be added here as well)." i whole heartedly agree with this statement a standalone amp provides better sound and its cool you can play the singer anywhere you want but it simply isnt the best overall sound, -> i know this is a violation of the rules but hey just wanted to comment on it a dsp is the icing on the cake, but you need a good cake before you can decorate it if you have money to burn this much for the unit and 500 for a 12 channel tune and money isnt an issue go for it, however if you want value just stay away

Pros: 8 channels at 25 watts complete control with eq and time delay can use active crossovers small form factor

Cons: underpowered, going straight from headunit into a lc4.800 makes a big difference even when eq is flat

No more overrun with my speakers

Robert from Jeanerette LA on 11/5/2019

Verified customer (What's this?)

Close your eyes and place the singer wherever you want with the time alignment. Now that's cool. And all from your phone which is where my music is played from anyway. Oh, tell your factory system to take a break from screwing with the equalizer every time you raise the volume, this thing has Bluetooth direct to processor included. Then the included remote display in case you don't want to work your volume or app adjustments from your phone. I have a JL Fix, JL HD600x4 and HD1200 with dual JL W6 10"'s with rear Apline "R" and front Focal KX2's . I am impressed with how clear my speakers now play. With the crossovers and crossover types and many fall off settings I can tune it to the way the artist intended or to what I like. Alpine is going to sell a million of these at this price.

Pros: It's has every option and is included.

Cons: I just can't think of not one thing.

Awesome Sound Processor

Crutchfield customer from Flagstaff, AZ on 9/20/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I went with the Alpine PXE-0850 to replace the JVC Tweak in my sound system. The Tweak is a good unit and it made my sound system sound great. I decided to go with the Alpine because of the additional features the JVC did not offer. I really enjoy the wireless Bluetooth connection, which allows me to make changes to the system without having to use my laptop computer. The wireless connection also allows the user to operate the system without going through the head unit if desired. The remote control also allows the user to control the system and change the preset system settings on the fly. The alpine unit allows for a variety of connections to allow versatile connections in different systems. The Alpine allows for high/low inputs, 25 watt per channel into 8 speakers, 12 separate inputs and a variety of sound settings to perfectly match the owner preferences. On the con side, the unit is pricey but it will be the last sound processor you will need to buy for your system and it allows for growth as you learn to utilize the many features of the Alpine. You won't be sorry you went with the Alpine sound processor.

Pros: See earlier comments.

Cons: See earlier comments.

Sound Tweaker's Paradise

Crutchfield customer from Alpharetta, GA on 2/2/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

This is a great unit and sound tweaker's paradise. The unit replaced Bose amp that I really didn't like in 2017 Mazda CX-5, along with a new set of ScanSpeak Revelator woofers and Illuminator tweeters replacing Bose. This was complemented by a power JL Audio PowerWedge+ powered subwoofer. Pretty much all the settings like crossovers, levels, polarity, delay, 32-band equalization (graphic or parametric) are available through the Alpine PXE-DSP app (on iPhone that was connected over Bluetooth to Alpine unit). One of the interesting features of the unit is Mixer that allows to connect multiple source together and mix the signals. For example, one could connect an RCA cable from a portable music player if headunit does not have one. It also allows streaming music over Bluetooth directly to the unit as well. I did have a few cases that the unit got disconnected and would not reconnect so I had to pull the plug on it (literally) and it reconnected fine and "hard" reboot. As far as power goes, while 25 x 4 does not sound like much, it *is* capable of driving my speakers (90 db sensitivity) to the volumes that make me deaf. I am guessing for some other speakers with very low sensitivity (like 84 db) it may have not enough power so just keep that in mind. Sound quality was very good although I bet a standalone amp would provide a better overall sound (can be added here as well). Happy with it overall; definitely recommended.

Pros: Easy to install, very easy to use. Virtually everything can be changed using iOS App while connected to the unit over Bluetooth connection. Sufficient power for higher sensitivity speakers (90 db woofers in my case)

Cons: Included wired remote never worked for me (was stuck on the loading screen forever). Bluetooth connection can be flaky sometime, requiring to disconnect power from the unit to be able to reconnect again.
