Where to start.
Unfortunately all I can do at this time is a direct comparison to the polk 70 series. Before I talk about sound I am going to mention some other things that I noticed.
The finish of these speakers is overall good. I can tell why they are b stock due to some imperfections in the clear but they still look great. No dents, dings, or chips.
The brackets that attach to the bottom and hold the spiked feet are a nice touch. When you attach the spikes make sure you have 2 pair of pliers handy. I used pliers and needle nose. With the spikes in place these are much more stable than the polks.
The knock test makes these seem like a quality cabinet. They are a thud compared the the polks hollow ring. Overall they just seem solid.
With the grills off comparing the appearance and the drivers it is a no questions asked win for the emp tek. The wife loves the appearance also.
The grills sit flush with the front cover and the quality is good. The have a wooden frame and stay attached well.
My only complaint is the binding posts. My GLS banana plugs and these did not get along and I ended up putting them in the hole that the speaker wire would go in and tightening them down. The pics do not show this because at the time I was swapping back and forth from the polk to these.
Now for some eye candy.
Now the initial plan was to keep the center boxed up incase I was not happy with the towers. Then I could send the center back and get a full refund. I had planned to keep the center tucked away unopened for a few days until I was sure I liked the emp over the polk. Well...a picture is worth a thousand words.
Ok, onto the audio. I have about 1.5 hours of moderate listening. I was able to really crank things up for about 5 minutes with the emp teks. I had no desire to do that with the polks because I already know the result.
Everything so far is 2 channel audio with no sub. I set the bass and treble back to 0 and disabled the audyssey for the most equal comparison I could do. These are being powered off of my acurus a3x200 which is fed from my onkyo 709
For tonight I listened to some avenged sevenfold, hurt, evanescence, and acoustic five finger death punch.
The polks have a bright in your face sound. Some vocals tend to go ssss ssss ssss at the end. I hope you can appreciate where I am coming from with that. The thing I do not like about the polks is no matter how much I jack with the EQ I cannot listen to these for any period of time without ear fatigue. Some voices tend to sound nasely IMO.
The emp tek's have a much different sound. They are more mellow and laid back. Not in your face at all. You can crank the volume as much as you want with no sound of brightness or ear fatigue. Everything sounds much more natural. One thing I really noticed was the accuracy of the bass drum compared to the polks. There is a firm attack and it is gone whereas the polks have more of a boomy lingering sound.
When I listened to a song at a volume of -30 on the polks, then switched to the emp teks and listened at the same level the overall volume and sound from the speakers was the same. Keep in mind the polks are 8 ohm and the emp teks are 6 ohm so my amp would be putting out a bit more power at the same volume.
For now that is all I am going to say. Once these speakers get some more play time and hours on them I will add some more. For now the clear winner for me is emp tek.
