I had tried the Ohm's on the Yamaha before I changed the setting to Large speakers and they sounded awful. I will have to switch them, right now I have too many things going on to have a play day experimenting. At my age, you know, it takes me a long time to walk across the living room with a cane or my walker...
Come to think of it, maybe the Ohm's sounded better because I remembered to turn on my hearing aid when I was listening to them.
I'm surprised at all the replies I got on this post, it looks like most of you other guys have a lot of time on your hands as well. At this point, also, maybe the post belongs in the receiver forum vs the speaker forum, but I guess it really is somewhere in-between.
As far as the comment on older speakers being more full range, the C2's were plenty full range, believe me. I had to keep the low cut switch on the Luxman depressed when playing cd's into the Ohm's, otherwise the speaker excursion on low frequencies might be damaging. I did have the foams on the woofers change some years ago, but Ohm now offers an improved replacement woofer, as written below.
I just looked at the Ohm website for some more info which is partially excerpted below, it turns out that the nominal impedance of the C2's is 6 ohms, so strictly speaking, I would have to go into the Yamaha menu and change the impedance setting.
Actually from what I can tell, the design and execution of the C2 beats the crap out of most speakers, and the Polk 70's are probably far more low end compared to the C2's. I remember when I bought them, I had listened to a ton of speakers, and when I listened to them, I said my god, this is something else (or maybe more colorful language used in the 80's)

The C2 is a 3-way, large ''bookshelf'' speaker with a 10'' woofer, low tweeter and dome super tweeter plus a vent on the front panel. There are two (sometimes only one) controls on the back for the tweeters. The cabinet is finshed on five sides in real walnut veneer and black formica on the rear.
This was the most popular of Ohm large bookself designs and it was known for being detailed and properly balanced at both soft and high listening levels.
Upgrade Options:
The C2 can be upgraded with our current model woofer which has the following improvements: the poly-cone gives a smoother transition to the tweeter for more natural vocal reproduction, the liquid cooled voice coil offers greater transient ability which handles the dynamic range of CDs and DVDs, Thet SubBass Activator reduces distortion, extends deepest bass, increases dynamic range and provides a self-resetting protection circuit to allow 200 watt amplifiers, the new foam surround has a projected 20-30 year lifespan.
The high tweeter can be replaced with our new 3/4'' metal dome tweeter for better dispersion of the upper treble which allows for more ''air'' when you are sitting off-axis.
Good Listening!
