Need help making a good decision on x4 in ceiling surrounds for the theater. I currently have Polk rc60is for my rear channels which are the weakspot in my theater My ceilings are a little over 10' high, so I was thinking of getting something in the 8" driver range. I unfortunately don't have a lot to spend and I have been drawn to the close out NHT IC4's which have a 87db sensitivity rating. I have read through tons of threads here regarding efficiency and still am at a bit of a loss. Here is some pertainant info regarding my system:


My rears have about 25-30' of speaker wire

My fronts are Paradigms with sensitivity ratings of approx 92db.

Reciever is a PIO Elite SC-07


Would the sensitivity difference coupled with the long run in speakers wire make the purchase of the IC4's not a good choice? Or should I keep looking?


Given this is not exactly a yes/no or black/white subject or question, what would you guys do? Keep looking or pick up some IW4's at a great price. If not, do you have a recommendation for something in the $2-$300 range? I am sure whatever else I end up buying should be TONS better than the Polk RC60's. Thanks for helping out.

The wire length has no bearing on speaker choice, only on wire gauge size.


The 92 dB vs 87 dB sensitivity difference can be compensated by the receiver channel level adjustment, and isn't a huge difference considering that the surrounds and rear may be closer to the seating position than the front speaker (in which case the adjustment will be less that the 5 dB difference).

Speakers will be fine. Your AVR is pretty damn nice and can drive 87db speakers with no problem. As mentioned above the difference between the front and backs will not be as bad since they will be closer to you. Many speaker lines have very efficient fronts with slightly less efficient rears.


Run the room correction program after you get set up. This will level everything correctly.
