Very very loud
howardjworf@aol.com 17.11.2025
Use: for the lowest of low ends paired with two TX308 or my two TS410 tops. To use this most effectively the main desk output goes through the sub and then to the tops after the crossover. Alternatively I may connect to a mono out from the desk (pre fader).
Pros: very loud indeed. Portable despite being quite heavy.
Has a standard pole mount, so no need for extra poles to mount a top.
Cons: very loud indeed! I have the gain control set very low otherwise the low end overwhelms the tops at moderate volumes - I prefer a balanced sound, not heavy in any frequency band. It's quite heavy. The box it came in seemed to weigh almost as much as the unit itself.
No Bluetooth or communication with series 4 tops. This really doesn't matter to me, as I only use Bluetooth tracks for ambient music at events, and switch the tops to full range for that.

Alto subwoofer
Morten Jakobsen 14.10.2025
Har købt denne subwoofer fra Alto. Rigtig god subwoofer med 12” bas. Den giver et rigtigt pift til mine aktive topkasser. Rigtig god subwoofer til prisen. Jeg er meget tilfreds med lyden. Køb den du bliver kun tilfreds. Tak til Thomann.

Erfüllt alle meine Erwartungen
One-Man-Symphonieorchester 11.08.2025
Gute Verarbeitung, guter Bass-Sound (in Verbindung mit zwei Alto TX 410) und aufgrund kleinen Abmessungen und geringen Gewichts sehr gut zu transportieren.
Einziger Mangel: Bislang keine Schutzhüllen im Angebot. Habe mir selber welche anfertigen lassen.

Simple workhorse
Cubeolah1 18.06.2025
Tested on an smaller outdoor concert of our stoner rock band and the woofer did a great job for a 12 inch. Bass and kick were projected very well, construction is sturdy and I really like the simple controls. No apps, just what you need. Small venue outdoors (one piece) is the the good maximum I guess, for indoor it has quite a headroom...
