    I've been watching the price on these for a while. there is no deal here, they've been listed at the advertised price for the last 2 months! there is no savings here what so ever.

  • Amazing speakers

    from Edmonton, AB on January 18, 2018

    Excellent sound, at low and high volume, with deep lows and crisp highs, great for music and movies - very happy with these speakers.

  • The Official Speaker Review

    from Red Deer, AB on February 26, 2017

    I did my research and these speakers get really strong reviews. I had big tower speakers and sold them, they were good but too big and they didn't match my poolroom. I have a set of 4 Polk Audio in ceiling speakers but needed a good set of book shelf speakers too. These are nice crisp sounding speakers, they are not tinny in anyway, thought I would need a sub but these speakers have a nice full balanced sound. The first song I listened to was Rhiannon - Fleetwood Mac and I heard things on that song I have never heard before. I have the receiver hooked up to my big screen, watched hockey ( the preds took the oilers 5 - 4 but on the game winning goal an offside should have been called but it wasn't, stupid ref) and the Daytona 500 and the sound was amazing. I'm not big into movies but I would bet these speakers would make any movie come to life. I played a few MP3's through the usb input on my bluray and they never sounded better. Are there better speakers on the market, well of coarse there are... but I am really happy with these. They didn't break the bank either. Taking sound quality, look and price into account I would give them 10 outta 10 (and I'm pretty hard to please).
