Dhl: I have a bit of recent experience, although with a different speaker. This summer I threw caution to the wind and did some nice crossover upgrades to my Tyler Woodmere speakers. I wanted to share my results in a dedicated thread, but I wanted to give you my thoughts now, so that you could have a bit more information to help you.
I swapped out the SEAS Millennium tweeters for the new SEAS Beryllium tweeters (exact size and fastener swap). I already had the Mundorf Silver/Gold/Oil tweeter cap. I am very, very pleased with the result. I did, naturally, swap resistors also, to match sensitivity as required. I won't go into a long rant, but this is super nice now. Multiple high freq instruments now are played simultaneously with realistic separation and space of each. Nothing harsh or tinny. And the presence is superb.
The tweeter mod was so nice, it made me long for better-defined midrange, especially upper mids where they are approaching high frequencies, as the mids did not measure up to these great high freq notes. Midrange caps are 120 uF, and I bit the bullet and bought six Mundorf M-Cap Supremes which total that capacitance. Yep, they are a big bunch of caps that take a lot of space. Well....was it worth it?? Hell Yes! A good bit of break-in was required, and right off the bat I only noticed more separation in upper mids. But as they broke in, I am getting a ton more definition, air and bass. Much more lower midrange/upper bass coming through now. The midrange drivers are 7", and in the big Woodmere enclosure I get gobs of bass. That is the biggest adjustment for me. I keep asking myself- is it realistic, or just bigger? Those big midrange caps are nearly broken in now I reckon, and I think it is both bigger and more realistic. I accomplished exactly what I was hoping to do in keeping up with the new tweeters.
Best part is that these improvements, while significant, do not ruin the overall sonics of the Woodmere speakers. They have simply been woken up. I could not be happier. Hope this gives you a bit of confidence to try your luck.
