I haven't seen any discussion for replacement/repair alternatives for the Mark Levinson center dash speaker on the 2010 RX450h. I've removed the speaker but don't see any obvious repairs to be made. I've seen mention of reglueing the dust cover, but this speaker does not have an easily accessible dust cover. The part number is 861600WL00 and the speaker has a plastic frame with capacitor/resistor components -- the frame is glued/soldered to the front -- see the photo below.


The OEM replacement is over $250. Are their any repair suggestions or aftermarket replacement alternatives?

I think you have to get the original speaker as this is a very small demand item. If it is not torn then it is likely a capacitor resistor etc that is bad. You could try to replace those and see what happens if you have someone who will do small electronics repair, it may be cheaper than a new speaker. Otherwise, I think you need to replace it with the same thing.
It happens. I had a tweeter blow out on my home theatre Paradigm center channel. I had to get a new one from Paradigm.

Here is an update on this speaker. I disassembled the speaker and found that the tweeter magnet had become unglued from the voice coil. I removed the old glue and glued the magnet back onto the plastic assembly of the voice coil. The only tricky part of this repair is the need to desolder two tabs which hold the tweeter assembly on to the front of the speaker unit. Once the solder is removed, I used a screwdriver to pry apart these two solder tabs.

I hope this helps anyone else with this problem. Speaker was easily reinstalled and now sounds great. Total cost of this repair -- $0!
