    White noise issues with b&w 805N

    hi,

    just want to share my (most recent) concern... got new sound processor and during setup while listening to sound levels I noticed quite a difference in tones between left and right channel. I then turned off EQ in processor, downloaded tone generator and found that tweeters (in area 10K+) do sound identical but woofers, say, at 130Hz and at 1000Hz do show a bit of difference. If I give then a sinus signal difference is subtle, but at wiz-saw signal it is very noticable. Pink noice also sound different.

    Speakers are not new, of course. So, is it something normal for such things to develop or should I proceed to repair? What I generally wonder about - in case if I DO proceed with repairs - how much can it possibly cost and what is it there to be repaired? Crossovers? Or woofers itself should be replaced, both of them? It will probably be close to the price of a whole speaker, right?

      I probably just should stop measurbating and start listening music again...

      But I think issue does exist to some degree - I tried placing speakers right on the table ahead of me and moved balance slider in computer volume control.

        How about swapping the speakers to see if the difference goes with the speaker or the location?

          Pairing 805S's with 805N's
          by sskim
          Even though I've never heard them side by side, I've read that 805N and 805S are quite different. I currently own a pair of 805S's and I like the idea of having the same 5 speakers as a 5.1 HT setup. Due to the budgetary constraint I'm thinking of perhaps buying used 805N's as surrounds. Has anyone...

          805N for 1,350 USD
          by phucdj
          There is one pair of 805N (2ndhand) on the internet adv which is 1,350 USD. Is it a good price? I heard that 805S is much better than the 805N. Is it true?
          I often listen to Dance/ Hip-hop/ Pop. Is the 805N suitable for the job (my room is 2.8m in width, 4m in length and 5m in height or i consider...

          by greynolds
          Finally, Proceed has made an announcement about the forthcoming upgrade for the AVP. Quite frankly, they are pretty vague about specific features and the cost, but at least they have made an announcement. What follows is the announcement from their web page (Proceed/Mark Levinson News):

          "Lex, I have switched my brand," I was telling out benevolent benefactor last night. I spent most of yesterday at a store in Kansas City called Audioport, a wonderful store with great staff. I was there with the purpose of improving the 2-channel dynamics of my Sonus Faber Concerto Grand Pianos....

          Upgrade Proceed PRE & PDP to a Proceed AVP?
          by timjclark
          I currently use a Proceed PRE as my 2-channel preamp and use the SSP pass through from my Rotel rsp-1069 for integration into my home theater. I also have a Proceed CDD transport and Proceed PDP D/A for cds.

          I am toying with replacing the PRE and the PDP with an AVP. The AVP being newer...
