Smart home sounds delivered purchase, really quickly!!... iv always wanted the sub, and listened to it and various stores, I really thought long and hard about purchase as it is an expensive item to to my already 5.0 surround sound system, not just for films but for music, I wondered long and hard, how good would it be? How much would it make a difference? And I though, iv heard it in stores and loved it, and I decided to just go for it, and I tell you now!!! You would never, and I mean never, ever regret it! Absolutely phenomenal piece of equipment!! It compliments the whole sonos system wonderfully, no matter what your sonos set up is, trust me, if you can do, do it!! And your never look back!!... also order from smart home sounds, not only 6 year guaranteed, but also the knowledge these guys have, will really help!! Make your eyes swell with excitement over this!!
