Alto TS 308 Powered Speaker

Many of the keyboards listed here have integrated speakers, which can be a great advantage particularly for home use, but most of the professional keyboards require external amplification. This can be achieved either with a keyboard combo amp or a single or pair of powered speakers.

Good quality powered speakers can be very expensive, but the Alto TS range is both good quality, loud, clear and comparatively inexpensive, which is why I recommend these.

For home use or even a small gig, the TS 308 is well adequate, but they are also available in 10”, 12” and 15”.
