Dear Everyone,
Approximately two weeks ago I received my rebuilt RM40s with the following options (or upgrades):
1) Supermax OXO (external crossovers with Bolder silver wire throughout)
2) MLS maple cabinets with 4 sheets of Blackhole 5 / cabinet
3) TRT capacitor upgrades
4) MLS Piano Black CDWGs (although I am currently NOT using..see below)
Improvements:
1) MLS cabinets have less resonance than the old stock cabinets
2) The MLS finish is superior to the stock finish cabinets. If you are going to order a pair of VMPS speakers
THE MLS FINISH IS A MANDATORY UPGRADE!!!2) Bass sounds cleaner and deeper that the old pair of RM40s
3) Midrange and tweeters are cleaner than before
The only issues I have are with the newly designed MLS CDWG grills. I wish that Brian would have kept the original design of the CDWG that incorporated a grill cloth.
Issues:
1) The piano black finish shows every fingerprint and minor imprefection.
2) The lack of a grill cloth over the midrange panels and ribbon tweeter provides no protection from the physical surroundings (a big concern if you have children).
3) Looking at a grill cloth is more pleasing than looking at raw speaker drivers (which is a big issues when your speakers are in your living room and you don't want to upset females).
I wonder if Brian could have MLS build me a set of CDWGs with cloth covering the entire grill.
So for now I am using the rebuilt RM40s with a standard speaker grill. When using the standard grills I have found it necessary to turn down the treble pot to 10 o'clock position, but I have left the midrange pot at the 12 o'clock position.
With or without the CDWGs the speaker sounds absolutely amazing and easily competes with speaker costing 2-3 times the price. With the stock finish, one could always noitce that more expensive speakers had a nicer finish..this is no longer the case with the MLS cabinets.
Best,
John
