In which direction are you an hour from Chicago? I'm near Rockford and if you are close by I would like to come and take a look. You can PM me if you wish. Jeremy

Blackhawks are in Sweden also to play Florida. I'm hoping for big things this year from the Hawks. Hopefully Hossa will be able to play this after all the money they are paying him. Jeremy

I about pissed my pants when I saw you list it for sale. That amp is at the top of my list. If you decide to put it back up for sale let me know. I am interested. Jeremy

Put me in line if John does not want it. I have an SA7800 that could use some cosmetic parts if yours ends up being a donor. Jeremy

Al, Well, if you ever decide to sell the Oris /AER combo, let me know. It may be out of my range, but i'd like to at least know about it if you ever sell. You did a wonderful job of prettying up your wood horns. Mine are in a box so you only see down into the throat, so no pretty for me. Thanx for sharing your project. I think we need to get a compilation thread of all these DIY tractrix projects and sticky it. Jeremy

What is that in your avatar that you are replacing, Oris w/ a full range? How does this compare? I have built these 2" tractrix @225 Hz and I like them, but now I want big round horns. BTW nice job! Jeremy

Isn't there a "Great" big lake in Ohio?

Dennie already covered the 1st two things I would try. If nothing changes you and you have narrowed it down to the speakers, I would try swapping crossovers side for side and see if the problem follows the crossover. I would be suprised if it is the midrange driver itself. The diaphragm should either be good or bad. I don't think there is any in between. I have never seen a degradation in sound from a diaphragm. If the problem stays in the speaker when switching the TT or amp, then my guess is

Bose Acoustimass?

I saw them the other day when they 1st came up. I too wonder what they are. They are local to me, but I have no interest. Same seller was also selling some Marantz speakers along with some electronics of no real value. Jeremy
