A Serious Upgrade for Bass-deficient PA Setups

The Alto Professional TS18S offers a rock-solid solution for bass-deficient PA systems. This powered subwoofer's high-efficiency Class D amplifier delivers a hefty 2,500 watts of rafter-shaking low end via a premium 18-inch driver with a 3-inch high-temperature voice coil. The TS18S integrates effortlessly into any live sound setup, boasting dual combo inputs and XLR outputs, dual XLR thru ports for linking, user-selectable EQ presets, and a phase alignment switch. This active sub is eminently roadworthy as well, sporting a rugged, internally braced, front-ported MDF cabinet with an integrated 36mm pole socket, a mark-resistant splatter-spray finish, and comprehensive protection circuitry. The Alto Professional TS18S is a surefire method for upgrading an underperforming sound reinforcement system.

2,500 watts of thunderous low end

Armed with 2,500 muscular watts of Class D power, the TS18S is one of the most formidable active subwoofers in its class. The TS18S comes loaded with a premium 18-inch driver featuring a 3-inch high-temperature voice coil, yielding thunderous low end all the way down to 29Hz. Show after show, night after night, the TS18S is engineered to elevate the low-frequency output of any live performance in permanent install scenarios and mobile setups alike.

Brimming with high-tech features

Here at Sweetwater, we're impressed with how much functionality Alto Professional packed into the TS18S. For starters, it includes two combo inputs that accommodate XLR and 1/4-inch connectors. You also get two balanced XLR line outputs and two XLR thru ports for linking. User-selectable EQ tunings automatically tailor the TS18S for various applications. A phase alignment selector switch rounds out this sub's outstanding feature set.

Engineered to withstand the rigors of live performance

The TS18S is a powered subwoofer built to last. It's housed in a near-bulletproof, internally braced, front-ported MDF cabinet with an integrated 36mm pole socket for simplified speaker installation. Its mark-resistant splatter-spray finish will continue to look great, even after several seasons of punishing use. You also get electronic clip, thermal, and transducer overdrive protection to safeguard your sub against all sorts of road-borne hazards.

Runs Silent-Runs Deep

After an exhaustive research both reading and listening to reviews on the Alto TS18s sub I decided to bite the bullet and just go for it. The very first time I engaged this sub with my QSC speakers and my Allen and Heath mixer I was totally blown away. The lows were beyond what I expected and it really delivered as advertised. This sub was at the lower end of the price point of many other subs but it offered a higher SPL than most of the others and this was exactly what I was looking for, truly a no brainer I cannot express how pleased I am with this purchase so if you are on the fence as I was debating on a sub rest assured the ALTO TS18s sub will fulfill your deepest needs.Thank you ALTO you've completed my System quandary.

Holy crap!

Needed a new speaker setup and was on a very tight budget, these fit the bill perfectly. Have only tested them out in my workshop, its 2000 square feet, and was only able to turn subs up 25%. Even at that they were hitting very hard and loud. Also purchased a pair of TS412 and the sound was incredible, clear and very balanced. I hooked them up several different ways. First connected to the subs then out of subs to tops, these have all the settings with a push of button for crossover. Then tried connecting to tops first and out of tops to subs, again all crossover settings with a button. Both of these worked very well, sounded great. The last was, i used our X32 matrixes (main left and right, right and left subs) to go into each sub and top. This gave much more control over the system and really woke them up, sounded amazing! I highly recommend the Alto on a budget, cant tell how reliability will be yet. I plan on gigging (a band) with these this fall so i will update on how well they perform.

Great powerful sub

I just used a pair of this newest Alto TS18S powered sub at an outdoor party with about 250 guests. I may say at this price point of less than $, this should be one of the hard hitting subs I had. Terrific low end and didn't clip at all the entire 6 hours of non-stop banging at high volumes. Weight is manageable and easily can fit a pair in a small SUV.
