I just got in my replacement towers yesterday and was able to get them set up (thanks Alex for making the process very pain free even if it took a little bit of time). These ones arrived damage free, even though the spikes had again come loose in one of the boxes. I'd recommend eD looks into a more robust way to secure the spikes because they worked their way out of the bag in 2/4 towers I had shipped, but they only managed to damage one of them.
I promptly set up my towers and moved my former fronts to the surround position and rand Audesy on my Onkyo 605. I then played some Smashing Pumpkins MP3s (yup just an MP3) our of my PS3 and was very surprised by how good they sounded. When I have some more time maybe I'll throw on some actual CDs to get a better idea, but the even the MP3 sounded great. Very full sound and the highs were better than I expected given my experience with the 6t6 mtm center I have.
I also want to point out that this was all with a sub optimal room layout. My Right speaker is partially obscured by a couch and my left speaker is slightly (maybe 4") closer than the right one. I know it isn't great but it's the best I can do in the apartment I live in right now. I was able to compensate for a lot of the problems with EQ and gain adjustments.
The towers sounded so good though that it actually got me a little worried about my 6t6 mtm, which seems to be very lacking on the highs compared to the towers. In the context of the towers it actually sounded a little muddy. Unfortunately I'm forced into having my center channel below my TV resting horizontally with very little clearance above or below it (there is plenty of space to the left, right, and behind). It is also slightly below an ideal listening level (which would be right in the middle of my TV). I'm wondering if the muddyness of the sound could be due to the positioning of the speaker. If it is, then that's ok and I'll assume that any other speaker would be subject to the same problems. If the speaker itself is lacking or worse yet I somehow have a blown tweeter (it has been this way since it shipped and I would be very surprised if this were the case) I'd be a little worried. It never really seemed like an issue to me until I noticed how much more my towers fill out the highs than the mtm does.
What is the best way to take off the grill on these speakers? Do they just pop off. I tried getting the grill of the mtm off, but it is in an awkward place (can't get it out without removing my TV and taking the glass top off, there is a metal ring in the stand that blocks the top of the speaker but it is not in the way of any of the drivers) and I was afraid to pull at it too hard.
All that being said my immediate impression (only a couple hours of listening) is that I would strongly recommend the 6t6 towers and eD in general. The wait was long but for 500 bucks I really think it was worth it.
