    • Good quality for price.
Style: Subwoofer
This speaker is awesome. I’m considering getting a second to have stereo bass. I do wish I could turn it down a bit lower than it can by default, but that may have more to do with my board. I have it in my basement to entertain friends and used it for my wedding. It filled a small hall that sat 78 with bass. ... show more

    • A great great buy
Style: Subwoofer
Did a ton of research before buying this. I splurged on a totally oversized sub to have in my garage setup and use at spirts tournament once a year. The sound out of this product is super super good. Very deep bass even at low volume, definitely FEEL the bass and brings a true depth to the music. I have it paired with a modest pair of alto 10 250W that I already had (probably 8 years old) and it still makes for a super solid set up. If you want to do true DJ gig you probably need bigger speakers, with more power, but the sub is an absolute no trainer. Super sturdy construction, very deep handles make it easy to grab and lift. Wish it came with casters but you can mount some on, so not a big deal. A must have if you are in the market for a subwoofer ... show more

    • Alto TS18s
Style: Subwoofer
I bought these to use with my band. Was skeptical when I bough them...I am kind of an equipment snob and was thinking along the lines of Turbosound or RCF. I figured for the price I could try them and if they sucked...get rid of them and get something else. They came in and I hooked them up and they sounded pretty good. They aren't a JBL or an RCF or a QSC...but they weren't priced like them either. They definitely did a good job and the money is well spent. The 2500 watt rating is peak power and rms is 1250 watts I would assume. I decided to pick up two more and I think overall they are a solid value. I can recommend them if you don't want to pay an arm and a leg and still have a repectable sub. Build quality is good...appearance is nice, and the really don't sound bad. I give it a 4 instead of a 5 just because the power rating is a little deceiving...in my opinion. ... show more

    • Awesome Upgrade Fills The Room
Style: Subwoofer
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. ... show more

These are great. We bought these as a second set. Only hassle was signature required by Fed Ex and them not arriving when they were supposed to. Lost 2 days of work waiting.
