You guys have some pretty awesome HT setups. I'm definitely jealous. I'm currently in no position for an HT setup, sadly. I do however have a decent HT receiver that is barely being used, definitely not for it's full purpose. A bit of a shame.
I am however into music production, so since my audio setup is in my room and does NOT want use of Hi-Fi speakers, I run nearfield monitors in a 2.1 setup.
I own and run a pair of Mackie MR5mk2s. They are active. A bit different than what this forum is aimed at speaker wise and setup wise, but thought I'd share anyways. For just over $300 for the pair, I couldn't be happier with the sound quality. Best sound stage and imaging I've ever heard in my life. I haven't heard THAT many monitors, but these definitely rival more expensive ones for the price range they are in. Blow my old Yamaha floorstanding speakers away that were paired with my current Yamaha receiver as front L/R in terms of clarity and imaging. As expected though. I only run the sub when listening to music, if I'm doing mixing/music production the sub is usually off. I went for an 8" so it would blend very well with my monitors, and it does it GREAT and it's only seeing roughly 100 watts. I plan to buy a new 300 plate amp for it soon but you know, money.
Picture of my current setup. Realllllllyyyyyy need a new desk. Also, excuse the wire clutter and powerstrip all behind the desk. It's really there for ease of access. There's a lot of wires involved because of the mixer and all my USB stuff...... Computer running all of this is a custom gaming rig I built that is pretty high end. Picture of custom sub too. Usually down firing but have been testing different positions.
