First of all this sub really sutable for ur small room but it really good sounding in medium vol.
If you want to use this as 2.1 style (computer user).

I got this small one from second store in Cambodia around 15usd only n still good coditions(work well)
So my first try with my onkyo AV , Yamaha NS-10mm _Hip Hop song n good sound out of the box. when I move up the vol bass distorted happend. I use this as a second sub for my main BOSE lifestyle right now n listen to some classic music becos it can be also adding some soft bass to that song. I like to listen warm music. Yamaha done well with some of their funtions on this one, Auto power off, High Cut... I planned to buy SW160 subwoofer product from Yamaha. In Cambodia, Phnom Penh price around 195$(VAT).
Thank you.
