The sound Quality is excellent, I thought that they would come with The casters on them or have them in the box. When I put the covers on them I realized that if I couldn't us them if I put wheels on them. I have had them since last Thursday. As far as sound quality and ease of use they are exactly what I wanted. I still have to figure out how to work the ethernet input. But all in all I am satisfied with my purchase.

I have been using JBL speakers for over 30 years. My newest system consist of four JBLSRX818SP Subs and two PRX 835 tops. they are used weekly, they have been reliable with no fault from day one right out of the box, producing clear accurate sound. I used the WiFi app made a few choice EQ settings for my preferences and haven’t done any else. The system is quick and easy to set up. I recommend the castors for the Subs and a small hand cart for the tops and I wrap all the speakers with the custom sized JBL bags that protects the speakers from the constant loading in and out of Venues and events. They look brand new even with some of the boxes going on 2 years old. I highly recommend the JBL SRX818SP.

I bought two of these to match my SRX815p. They sound amazing deep bass. I am using the On Stage SS7747 crank up subwoofer poles. They are very sturdy to hold up the 62lb SRX815p. I would definitely recommend.

I bought 2 of these subwoofers and so far I’ve only have needed to use one on my events. They have an extremely loud bass that’s why I have only used one of the 2 that I bought. I pair the both with my SRX815p speakers when I test them out and it just gives you the perfect combination sound together... My only complaint is that they are a little on the heavy side and a bit expensive...!!!

This product is great! Love the thickness of the bass. Very lightweight, especially once you put casters on, they're easy to manuver! Great product definitely interested in getting another.

As expected

Arrived on schedule, price was right.Quality amazing.So far I think all my future gear will be B-Stock or Used from PAS. Great value.This sub definitely does the job and emits the right notes.. it's not a "umph-umph" but a very musical, deep and punchy sub.Easy grips, and easy to transport, really robust.

Great Sub

I purchased three SRX815P and two SRX subs for my church. We have been using them for about two months and I could not be happier. I was planning to purchase the PRX series or potentially a different brand but the first time I heard the the SRX series I had to have them even though they were outside of my budget. I have had multiple comments on how great they sound. I am very happy.

Great Sub if discounted.

Had the EKX-18SPs which are great subs but down go low, low. I was going to upgrade to the ETX-18SP I rented an ETX-18SP once and loved the sound. I wasn't happy with the weight but everything else A+ but fate stepped in:Pro Audio Star didn't have any in. So wanting to upgrade soon and didn't want to chance not having any subs I looked at the JBL SRX818SP. Specs were basically same as the ETX-18SP with the exception of watts. I found my first one for $900 with a cover on the marketplace and bought my second one from proaudiostar. I finally used them for two events. They sound great. The base goes low and deep and it does hits pretty hard. I will say that the ETX goes low as deep too but hits slightly harder. Is the difference worth lifting 30bls more equipment per ... MoreHad the EKX-18SPs which are great subs but down go low, low.

Not to me. Now we're done with the good, let's talk about the bad. I think it's over priced at $1599 especially when you can get the 828SP for $400 more. The software isn't very easy to use. Given my extensive background in IT I eventually figured it out but for DJs who aren't network savey may find it challenging.You have to pay for casters (ETX comes with casters).Overall, great performing sub especially for the weight. Not worth the retail and the software can be a challenge but they have been discounting these subs as of lately which can make it a great deal.

JUST BUY IT

Stop looking and just buy it. I am completely blown away. Hits hard and deep. I bought this to replace a pair of PRX series 15 inch subwoofers and there is no comparison

Solid Piece of Sound Reinforcement

A great piece of gear. Solid sound, very smooth and even response at low or high levels.My only issue was I never could get the computer interface to work properly. After hours of trying, I finally gave up and I just adjust it from the back, so four stars.
