Great item, ive ordered this product from other company's and it got badly damaged twice, and was returned, took the gamble with amazon and I couldn't believe 2 men turned up, delivered the item with not one mark on the box, this is a serious budget subwoofer with the right tops will outperform others twice the price, alto is not everyone's cup of tea, but they are good value for money. Would I recommend it... well yes but remember it's a budget midrange speaker,

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

Muy contento, tengo dos Alto Ts415 y es el complemento perfecto para ellos. En varias ocasiones me han felicitado por la calidad del sonido. Hace poco compré el segundo subwoofer y estoy deseando poder hacer el montaje completo para probarlo. Si quieres una bajo potente es muy recomendable

Costo/beneficio es bueno Es un bajo muy compacto, la bocina de arriba es de 15" pulgadas para que se den una idea, sin procesar suena decentemente bien Lo recomiendo, buen sonido, nada bultoso y sobre todo a un buen precio a comparación de un QSC, Mackie o algún Electrovoice

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.
