    • Rare find for a JBL speaker

Excellent well built speaker from the warehouse. Great price and quick delivery.

    • It leave me wanting more..... More SRX speakers
Size: 12-Inch Two-way Speaker Style: Powered
For starters, the SRX line is probably overkill for my use: DJ indoors, for 100 people. Be aware that these are not your normal "plug-n-play" speakers. They are programmable. Before your first use you really need to plug them into a computer and program your own EQ preset. They come flat, and most people are going to feel disappointed with the performance until you program them and create your own preset. This might be more technical and more of a PITA than you want to deal with. I paired the SRX812P with my Yorkville 18" LS801P sub and it was magic. A single SRX812P out performed BOTH of the other main speakers I was using. I turned my old mains as far up as they would go, and the single SRX812P was so loud I couldn't hear them anymore, and it still had a LOT more headroom. The only complaint I have, and its really irrelevant, is that its not going to blow you away in the bass department. Its a great mid range speaker. That's why you pair it with the powered subs. ... show more

    • Earthquake in a box.
Size: 18-Inch Dual Subwoofer Style: Powered
I play drums (and run sound) for a 6-piece band, covering classic and modern rock. I was using two Peavey 118D powered subwoofers to provide the bottom end, and they did okay for indoor gigs; however, we have some outdoor gigs coming up, and I realized the 300w Peaveys weren't going to cut it. The sound guy at our church demo'd this sub for me, and I was BLOWN AWAY. As a drummer, I like fat, punchy bass, and this SRX828SP delivers. The pressure coming out of the front could resuscitate an unconscious person! Not only can this thing move serious air, the sound is very 'controlled', not boomy (with the settings we use). It's just big, fat punches to the face with each kick. I ordered this speaker used (like new) for $1,700, and paired it with two JBL PRX715 powered speakers. I hooked all three speakers up to the DBX Driverack PA+ and our band's sound has been revolutionized. Just be aware - this sub is huge, and heavy. Definitely a team lift into a truck bed. It'll likely fill a truck bed by itself, leaving little room for other equipment. ... show more

Review Image by shoundeya almond shoundeya almond
I am very happy that my speaker arrived today as expected. The sound quality is good just needs a little tweak out of the box .JBL is nothing short of great to my knowledge. However I’m very disappointed in the fact that my speaker arrived damaged. I love the sleek clean look that this speaker has but I am not satisfied with the dent across it. I wasn’t sure who to reach out to about this and on top of the $1,500+ that I paid for the speaker I also purchased the nearly $200 warranty so hopefully that’ll help my experience be amazing instead of mediocre. ... show more
