Adding sub question

140 Hz is fairly high for a crossover point to subs. Bass is going to be directional to some degree at that point, which will make integrating the subs more difficult. Might want to get something that can handle time alignment at this crossover point, depending on the locations of the subs.

140 hz is possible because the PLW-15 has one of the fastest responses in subwoofers these days. You cannot point out my sub. At 80 hz low freq. start to be touchable. By using it to 140 hz the overwhole sound improves a lot. I owned the Valhalla for over 12 years and sols a lot of them. Nordost is a brand you need to use very precise. The problem is that it is not complete. You Always need different brands to get all the essential parts what should be there for the absolute sound.

thanks for all the input, I am leaning towards starting with cables and also using the Sony to see if those 2 combined would help. BTW I when I stated `push` the Tylers I did mean turn volume up to get the low end louder, but like I stated top end got real harsh, I have tried moving speaker in from side walls and out from rear walls, helped some also. Will keep all posted after cable and source are done. Would an Audysee unit do room correction?

I don't understand the posts of Bo1972. What does fast mean in terms of a sub aimed at reproducing LF? Why stereo for subs rather than mode smoothing, given the pyschoacoustic literature on LF localization?

If I were OP, I'd pay attention to Al, and order an Oppo 105 that can be returned if it doesn't solve the problem. It should settle the impedance mismatch issue.

I think I found the answer!!! Went to a local dealer in WI speaking to him of my issues, he sent/loaned me a pair of Analysis oval speaker wires, they are their demos so the are broken in, a voila! 80% harshness gone. Way more pronounced on the low end, just may be the ticket! BTW these we not a biwire pair, What are your thoughts on putting jumpers in and running single wires instead of biwire(fyi the Tylers are setup for triwire) I currently have a jumper between the tweeter and midranges.
