am in the process of upgrading my speakers for my Home Theater. Ya know, this all started out several days ago with a passing thought of "Hmmm...I'd like to get a better subwoofer..." (currently an Audiosource SW10) and "I bet I could do it for about $400." Yeah. Right. Sure. Read on... Here's what I've done so far... Putting my Inifinity Reference 2002.2 bookselfs from the front to the rear to replace the Infinity Minuettes currently lurking somewhere back there...I can hardly hear them...not sure I really want to anyway. Just ordered (like, 10 min. ago...)Axiom M22Ti to replace the 2002.2's up front. It was between the Axiom (unheard, yet highly recommended by a rep. I spoke with at SVS) and Klipsch rf-15, which I heard yesterday compared to Paradigm Phantoms. The Klipsch buried the Phantoms overall. I am uneasy about buying main speakers unheard, but reviews at audioreview.com are make the axioms sound basically bullet proof...very strong in the midrange and high end...which is what I need. I didn't feel like I was getting punched in the kidneys quite as hard given their cheaper cost as this project spirals out of control. Also bought the VP150 center to compliment the M22Ti...of course...replacing a JBL center speaker which I have always hated...which my ex-wife picked out years ago. Why did I listen to her. Why did I marry her? Ciao baby! Now for the sub. Is the 25-31 PC+ reeeeeeeeely worth the extra $175 over the 20-39 PCi? Room is 15X16, with an exposed half wall to the left leading to my kitchen, which is 13X16. This will all be powered by my Yamaha RX-V795a receiver. So you can see how this has snowballed completely out of control. Just give me your damn thoughts on the sub. okay? Anyone tempting me with a snide..."Ya know, your reciever is nice...dont get me wrong...but have you listened to "X"? Ya might wanna give it a listen..." will be publicly flogged. I am in hell.
