Review: 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
Review: Great item, ive ordered this product from other company's and it got badly damaged twice, and was returned, took the gamble with desertcart 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,

## Questions & Answers

**Q: I bought this because i thought once linked you could play music on both linked speakers. It only does when your source is connected via btooth. Why?**
A: Not sure I understand your question. Using the Bluetooth linking function you will only be able to play music on both speakers from a Bluetooth source. For non-bluetooth sources you will have to either: a) connect one speaker to the other via an XLR microphone cable from the Mix output of one, to one of the built in mixer inputs on the other. In this scenario, the output will be mono. For Stereo you would have to have a separate mixer feeding its left and right master channels to each of the speakers and your input source would have to be feeding a stereo channel on the mixer or two mono channels, one panned full left and the other full right. If you don't have a copy of User Guide for your speakers you should be able to download one from the manufacturer's web site.

**Q: is the price 299 pair?**
A: Hi, Alto Pro support here! The price is for one speaker. For further support, please feel free to contact us - amzsupport@altoprofessional.com

**Q: Is it needed battery or direct power cable? And also can I connect with other speaker with it?**
A: Hi, Alto Pro support here! TS410 is a mains-powered speaker and does not feature the ability to operate over battery power. You can link a secondary speaker by connecting a standard XLR cable from the Mix Out on the TS410 to the input of your chosen loudspeaker.

**Q: Hola, deseaba saber si se pueden usar como los parlantes activos frfr con Multiefectos de Guitarra? Gracias. Saludos!**
A: El TS408 es compatible con su pedal multiefectos, sin embargo, los altavoces HeadRush FRFR presentan una respuesta plana de rango completo que es mejor para reproducir el sonido de su guitarra.

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
