I think I have changed my mind about doing wood frames on my 2.7s after doing the mod of the damplifier mod on the 2.7s and comparing them to my MG10s. The main goal behind doing the wood frame mod in my mind was to improve the issues involved with MDF and Magnepans. With my MG10s I heard a big difference going from MDF to wood. However I would say that now I am in wood frame country after using damplifier of stock 2.7s. The difference in sound is just amazing. The insane part is the differnce that it made on the MG10s. It took the MG10s to a whole new level of image clarity and overall detail. It has done the same thing to my 2.7s.
I am now beginning to work on the individual magnet pieces on the 2.7s. This is a long and tedious cutting process. I am not totally sure if I am hearing a substantial difference with the individual magnets. I have been experimenting with placing in it places that I think would clearly need dampening like the magnets that are located between the bass area and the midrange and on the double wire section of the bass section. I think I am hearing more refinement in the bass in that it is more detailed and has more attack to it. The problem is that I have been listening to my speakers and doing the mods at the same time. So it is beginning to blur. However I think the more damplifier I am adding the better it is sounding. There are some recordings I am listening to that I thought were harsh or brittle before that sound great and I have more resolution than before.
While I may have talked myself out of doing wood frames on my 2.7s I have in no way done so in regards to crossovers. Compared to my MG10s I am still hearing some veiling of material, though the 2.7s have a overall superior presentation by far. I have taken what Mart did with his crossovers and tweaked it a little bit as it seemed like I could get a little smoother response altering some numbers (Mart: Chime in with why you chose the values you did. Is what you came up with as good as it gets and I am doing something weird?) Really crossover mods regardless of framing and dampening always make sense. They provide better resolution for the driver to produce, which it will do all the better if it is dampened properly.
