New (used) speakers & successful experiment

I’ve gotten the itch to look around at speakers again. I’m still really liking my KEF IQ7’s but I wanted something…more. I’ve been listening to omni/bi/di pole speakers from Definitive Technology, Martin Logan & Mirage. I like the extra ambience and sense of space they offer, but each has it’s detractions. The ML’s offer tons of detail & space, but they’re very picky about placement, and you do have to be in the “sweet spot” both vertically & horizontally. Move just a little, and the soundstage collapses. The Mirage are a bit too diffuse, and the fact that my listening room is the top level of a split level house means the left channel has no wall near it for the reflected sound. I was looking at the DT 10BP (used) but the imaging wasn’t as solid as my KEF’s.

While perusing craiglist I came across a used pair of Polk Monitor 50’s. Not a great speaker, but decent in it’s own right. I put them up on two cinder blocks, and placed them behind the KEF’s facing the rear wall. The tweeter is very bright, so I tucked a small fluff of holofill over the tweeter, between it & the grill. There was also too boomy, so I stuffed the port with some foam. I wired them in parallel with the KEF’s. True, this lowers the impedance to 4 ohms, but I figure the Emotiva XPA-5 can handle it. So far, I have been able to get the volume as high as I would ever want without any clipping or strain. This arrangement also allows me to position the Polk’s independently from the KEF’s . The blend of the two different tonalities is very nice, and the added dimension to the soundstage is wonderful. Yes, I could have gone for another pair of KEF’s, but at only $150 a pair, I had to give them a try, and so far so good.





There is a shelf just behind my display from which I hung a piece of egg crate foam to tame the early reflections from bouncing around behind the plasma. An experiment that paid off.

If your speakers are up on blocks in the front yard...you might be a redneck. :p

Congrats on the new gear, Craig. Quite a fun week for you in terms of new toys!

Only $150 for the pair!

Hey, that sounds like a pretty sweet deal Craig. :)

I was thinking about those Mirage Omni's on sale at Vann's but this sounds like a great idea and fun to mess with. I have an extra pair of bookshelf speakers w/ stands layin around. Is there any reason if both are 8ohm, that I shouldn't try the same experiment?

Just make sure your amp/receiver can handle the 4 ohm load without issue.
