ALTOTS18S - 2500W 18" Subwoofer, Powered PA Speaker with 6 Selectable DSP Modes, Easy Setup, 137 dB, 3" Voice Coil, Superior Bass

I had the TS318S for 3 years and used it nearly 100 times, it was a good subwoofer and provided good sound for many events.Made the decision to upgrade to a pair of the new T18S subwoofers and absolutely love them. The crossover is better, the sound is fuller, the SPL and coverage area for venues is significantly improved. These guys were set up in a 50’x24’ venue with 11’ ceileings and I had that place FILLED with Bass. The awesome part is I didn’t even have them cranked above 70-75% of their potential.It’s a great value for the price and great work to Alto for the very noticeable performance improvements.Highly recommended.

Great Subwoofer. UPS box arrived Banged up. SMH. Scratched/Busted above Alto logo and Grille dented.

one will do, but get your hands on two? gahleeee it’ll knock your socks off. paired with 2 alto ts415’s on top, almost sounds professional. needed a 1kw+ generator to power everything but well worth it. neighbor camps weren’t too happy but it’s OUR music that counts.

The item was shipped upstairs down which added the sub speaker grill to be damaged.

It was really easy to set up and tune. And sounded amazing. It has good crisp clean bass and can get loud. If you're thinking about buying I would definitely recommend it.

These have always been really great speakers for your money if you get the TS series and if you could get lucky enough to get one not damaged. If they were packaged just a bit better i would try to order again but so scared of getting another the same way, I don't know what to do. Had to return mine as soon as I un boxed it, I was so bummed out. The way the package arrived is the ONLY reason it got 2 spars from me otherwise it would have been 5 even though it never got to hear it play. I an so confident it would sound great because every other one i have had exceeded my expectations

I use it as a drum monitor. With a TS415. I have no complaints.

I knew it was powerful but man this thing is ground shaking powerful. I use it with my DDJ mixer and ROKIT 8's. A thing I found weird was that the bass doesn't really kick in until you turn past -3 db, which is already too loud and drowns out my speakers. Another thing is that you can't really hear the bass if you're really close to the sub but I think that's how directional subs work? This sub does really good on the low lows, I don't recommend if you need to hit the low mid freq. range.
