Etx sp18 powered sub


Absolutely an amazing subwoofer. The guy from Sam ash audio was great. He suggested this sub for my indoor and outdoor events. I was not disappointed the bass definitely carries



Definitely, ready to buy another pair.


Excellent subwoofers, clean, powerful and crispy sound. Completely satisfied!



again & again


Amazing sound coming out of this thing, and as always, amazing service; I buy all my gear from Sam Ash!



One of the best on the market


The ETX 18 Sub is hands down one of my favorite powered Subs out on the market. Its unbelievably powerful, with 2000 watts of power on tap for any need. Also the fact that you can tune each individual speaker to the room. These subs are without a doubt m go to recommendation for any application.

Amazing bass!


Wow what a subwoofer. This sub is not only loud but it projects very well into a crowd. With an 18" driver this will also reproduce lows really accurately. This is a real hands on product review from Ken @ Sam Ash Buffalo Grove

Amazing bass for live settings


This sub is incredible for your smaller and bigger gigs. I've done some shows with two subs and the bass was so strong and pushed very well I was happy I could easily cut the level so it wasn't to strong. One sub can easily handle a room of 200 people or more depending on the setup. Overall the best sub Ive used in recent years. Hands on review by Branden Sam Ash Buffalo Grove.

All About That Bass!


If you need a little (or a lot) extra bass, this monster of a sub-woofer will not disappoint. Take your low end to the next level. LCD monitoring is the icing on the cake.

Very powerful, still crystal clear.


WOW, this speaker is just killer! I have been letting my friend use one of these in my friends mobile dj setup along with a pair of jbl prx712 top cabinets and it compliments it very well. In Fact, a few weeks ago we did a gig with about 150-200 people on the dance floor in an outdoor venue, it was under a tent, but everything was loud and clear. The bass for just one sub is impressive enough. I did turn down the eq at 30hz to get a little more output. Every other outdoor gig we have done I have had more than enough output and can't believe how much really low bass this thing cranks out. Definitely recommend to anyone who needs more bass and low end in their life.

Really nice sound. 1800 Watts class D amp. EV has integrated an LCD screen to give better accurance to the settings. There is also EQ curve and top/sub configurations. These controls adjust automatically to give you the best sound for your rig. Wheels on the back protects the LCD screen and makes this sub easily mobile. 135 db peak SPL. Huge output!!! Look out QSC KW, got some competition. This is a real hands on product review from Brian @ Sam Ash Ontario.
