Alto TX 12S Subwoofer

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.
