Pretty cool
Light, small, and loud. Used 2 of them in a massive venue with 200 guests, coupled with the 12" tops. and they were great.

Don’t let the size fool you.
I paired this with a pair of TX208s to replace an old kam system. The amount of bass this can produce is amazing for the size! It’s much lighter than my old subs too which is nice.

Solid and Fast Subs that Punch Above Their Weight
These tiny subs are excellent value for money even more so with the recent price drop and have a surprisingly good sound out of the boxyes if you want groaning bass and a back pain to match go for the 18s but when it comes to the punch and speed that is critical to a tight clean sound these boxes hit the markrnIf you do feel the need to take the front cover off you will find a rock solid build quality in plywood with twin tuned reflex ducts not the usual hole or random piece of wood for a port The driver is not going to have a premium cast chassis at this price but it is well built with decent coil venting a large magnet to control the cone excursionsrnReal world power handling shows one of these to be a decent balance for a pair of most full range 12 speakers and a second only serves to Lighten the load unless you are looking for a lot of heavy bass dropsrnCriticisms Only one and that is that the textured paint finish is very Matt and marks relatively easily so covers are essential rnAdvice Read the manual carefully before using the presets as the back panel terminology may be a little confusing and can give you sound problems if you pick the wrong settings for your rig Also as this is a small cabinet its not very stable to support anything much more than a 10 cab on a polern

Alto Truesonic TS 212s
Did an outdoor party with one of these and pair of the new Alto 600w tops. They all sounded fantastic. Could not recommend highly enough. Filled a large patio area with good clean loud sound and I was only on about 40% of available power. Go on... Ave some!

Alto Truesonic TS212S Active Subwoofer Questions

Considering purchasing the Alto Truesonic TS212S Active Subwoofer? Have questions? Ask people who've recently bought one.
Looking to purchase a pair of these sub-woofers to compliment my EON615'S. If I use these with a 0.8m pole and the EON615's, are they going to be stable enough or will the EON615's weight going to make it too top heavy. (The EON615's are 21kgs)?
