New here, advice needed on M10's
Hello all! I have been a long time Polk person since I got some 5B's new in probably the late 80's.
Here is the situation.
I just got the new Harmon Kardon AVR 635 to run a Dolby Digital/DTS setup. I have 4 Polk Monitor 5Bís total but only use three in a HT setup where the 5Bís are in the front left/right and center and one is a spare. For the sides I am currently using a small pair infinity bookshelf speakers. I think it is really important to have the front three speakers matched but I wanted to increase the power handling of the L/R and get better bass response than the 5Bís can do. I just recently purchased some Monitor 10ís (M10ís) from ebay that I intend to use for the FL, and FR.
When I received the M10ís I found them to be damaged. Both of the M10ís each have a mid bass driver that is seized. I did read in the forum about the glue gets old and if they are dropped this can cause the damage to the drivers I have. I am currently working with the people I got the speakers from on ebay and UPS to work on resolving the damage to the speakers I have. From talking to Polk, I found I can replace the damaged drivers for about $48 each so about $100 to fix them.
When I ordered the M10ís, I didnít realize there were different tweeters that they could come with. My Monitor 5ís have the SL2000 tweeter and the mid bass driver is a 6502. The Monitor 10ís have a different tweeter (the one with the small hole in the middle and visible wiring going downward from the tweeter at about 220 and 300 degrees) and they have the 6500ís. I would like to have the high and mid range matched across the front so I was just seeking some advice on what others would do in this situation.
When I talked to Polk, they did say it would be a good idea to replace all 4 of the 6500ís because of the age and I can get the exact replacement. I think Polk said they sell the 6503 to replace the 6500. Since 2 6500ís are good, I could ebay the two good ones and get 4 6503ís. Is the SL2000 a drop in to the version of M10ís I have of would I have to change the crossover? Would that affect the power handling of the M10ís? I think I will be working out with UPS/seller to get about $100 for the damage so I think I am OK there. If I have to replace three drivers in each M10, that would be about $300.
The overall condition on the 10ís is kind of rough. They have some nicks, scratches and two of the clips that hold the speaker covers on were broken during shipping. It is not what I expected when I won the auction so I was seeking some advice from others.
Should I total the M10ís, take the $$$ and try again to get another pair on ebay?
Should I replace only the damaged drivers and cal it even or replace all 4? If I have to spend another $100, that would be OK.
Will the tweeter be a good match between the 5B center channel and the M10ís?
I am not really concerned about the appearance of the M10ís because I can fix that. I could move some of the SL2000ís from the 5Bís to the M10ís (if that is OK with the crossover/power handeling).
Thanks for any advice.
