I hope it does take you only a few days.
On to the review!
Now, the setup is quite far from ideal, but I tried to make it as objective as possible, along with the comparison to the Khan's.
I used my Mac laptop through analog mini jack to my Emo UMC-1 and powered by an Emo XPA-3. I moved the speakers to be equidistant from each other and the listening position. I used Direct mode to eliminate any processing and had the speakers playing with no crossover. The only thing I didn't feel like doing at 9:30 at night after working for 9 hours and working out was moving the couch that was slightly in the way.
I started with the TD12Xs. I'm sure some break-in is needed for the drivers, but take this for what it is worth. I listened to a few different songs of wide variety before settling in for serious listening.
Norah Jones - The Long Way Home
The bass. Not the bass as in the frequency, the bass as in the instrument. It was absolutely beautiful. I caught myself listening to it more and more as the song went along. I felt it was being played right in front of me. There was that slight bit of impact when it was strummed and then a fullness that faded naturally as you would expect. That woofer is something special I think.
Norah's voice was as buttery as it should be and was ear shattering as it should be when she went up top. Quite transparent, which I expected.
They imaged and soundstaged MUCH better than I was expecting. There was depth and width to the sound and it definitely pulled you in.
Cranking it up toward the end of the track, I started to get nervous about the drivers as the volume climbed, but the woofers looked to be in check and probably would have met the limit of the amp before the loudspeaker. I believe Vincent said the design is good for 750W, my XPA-3 can deliver a bit over 300.....I definitely didn't reach the limit of the amp and my ears were getting ready to call it quits.
E-40 - I'm Da Man
I picked this purely for the bass (frequency). These are full range speakers for sure. Fairly certain this song dips to low 30's and the TD12X didn't break a sweat, even when taking it to the same levels I did on The Long Way Home. I had never heard that song sound so nice (not that it is a song you play for deep listening
In comparison to my Khan's, the Khan's had more top end than the TD12Xs to my ears and also had a more robust bottom end even though a sealed design. The Khan's were not as laid back as the TD12X either. To my ears the Khan's were louder at the same volume position, but were definitely reaching their limits in full range. Keep in mind, the designers of the Khan's intended for these to be crossed at about 55hz and to be mated with a dual 18" LLT. The Khan's I believe are a 4ohm nominal, I don't know what the TD12X is. I was hitting 50 on my dial (out of 80 or 100) and normally I don't take it past 41 or 42.
Overall I am REALLY impressed with the TD12X. Almost....ALMOST enough to get rid of my Khan's, and anyone who has seen that build knows that is saying a lot.
Please ask questions on my impressions if there is something specific you would like to know that I have or haven't mentioned. I will hopefully get a chance to run some movies/video games through them as well to see how they fair.
