Here is repeat of a much earlier post to address your question,
They did sound great right out of the shipping boxes,but I haven't owned a speaker yet that I did'nt mod and get better sound.
Even though I did buy a upgraded pair of Di's from Eric,I have upgraded farther with even better caps,inductors and resistors and some wiring.
I started with the crossover on the woofers,
The heavy duty Jantzen coil is fine I didn't change it but I did change the single cap and got rid off the sand cast resistor,I don't like that type,I think they can be noisy.From day one when I got the speakers I didn't like cosmetically the blue colored woofers with my black metallic paint so I changed to the Eminence beta which gave me black cones the stock ones are the alpha's with blue cones.The physical size including depth are the same but the specs are slightly different.The beta's are 2 Db more efficient in their specs of the driver in free air and they give me better bass and dynamics at very low volume levels and they equal or are slightly better defined bass at higher volumes.I also biwire mine with a single run of western electric 10ga wire that solders directly in the crossover,and I use the same wire to the woofers.The beta woofers cost 60.00 a piece from us speaker.I hear just better defined bass maybe tighter and does measure 2 to 3 db down at 20hz in room.
Now that's the easy stuff,I took a look at the crossover for the tweeters and mids and decided to change all caps,resistors,and coils to better parts IMO but I did'nt change any wiring,It's ok and would be a lot of work.
Even though my speakers sounded very good once broken in I couldn't leave them alone because I knew I could make them sound better,I basically gained overall smoothness and a tiny bit of clarity and coherence without hurting but only improving the magical midrange that these speakers have by design.
I wouldn't honestly recommend that everybody that owns a upgraded pair of Di's would want to incur the expense and time involved for the noticeable but modest gains in sound.
Basically what I'm saying It's a lot of work and it took me 2 whole days to do mine.
Take the time and remove a couple of tweeters and maybe the lwr mid and look at the crossover and you will have to decide if you want to tackle it.
One option might be just to change the little bypass cap on the tweeters input to better quality.
Overall I would say I gained a solid 3% gain in improved sound in every sonic apspect that I can think of.
With these sound improvements It doesn't make me in no hurry to upgrade to any other speakers,but my digital front end has seen some improvements as well in the last couple of weeks and as my budget allows I'm going to purchase a Music Vault M7 music server and I hope to have the best digital that I have ever heard,I was a analog guy for many years but I have'nt spun a LP in 3 weeks and I'm not missing it one bit.
