Speaker Mods?

Hello:anyone knows who makes quality mods for speakers such as changing tweeters and upgrading the crossover?
i currently own a pair of paradigm refernce v-40-2 and while i like the amount of bass it gives the high freq could be a little harsh at moderate levels,i need a speaker about this size and found it difficult to find a small speakers w/the paradigm bottom end at a reasonable price and therefore an upgrade path may be a viable alternative,thanks so much.AL
my system:
sim audio moon i-5
resolution audio transport and dacs.
synergistic res ic and dh labs q-10 speaker wire,i'm looking for a more delicate and refined performance without
sacrificing detail and neutrality.
There is a member here with a set of Avalon Acoustic Eclipse who put a Eidolon midrange in place of the tweeter. I spoke to him one evening and he seemed truely happy with the mod, I would have tried it if I didn't have to cut larger holes in the cabinets. I am not sure if something like that would work for you, but there is a chance. That being said I am going to have to agree with the statements made above, I would not recomend upgrading those speakers in particular, money could be spent in other places having a better effect. Check out www.zalytron.com I know they can do everything you want to get done, they tend to help a lot of DIY'ers but I am sure they can upgrade anything, all it takes is $$$. Good luck
Why not try changing cables from a copper/silver hybrid (Q-10)to all copper? Since you have Synergistic Res. IC, try their speaker cables (I have the Signature 2 and find the highs to be smooth).

If that doesn't work, I would be inclined to replace the Paradigms rather replace drivers and crossovers.
Good Luck, Dave
Modifying speakers is really iffy. You really might want to think about just buying new speakers, especially since no one will ever buy modified speakers. Totem makes bookshelf and small floorstanding speakers with a lot of bass, and those can be found rather inexpensively used here on Audiogon.
Would tend to agree with Milo. Leave the drivers alone. Look inside the cabinet for opportunities to upgrade. If electrolytics are used, replace with polypropylenes of equal value, improve wire internally and stuff corners with cord weather stripping to reduce cabinet resonance. Total cost should be no more than $50 and if you still don't like the speakers sell them.
Yo Alfred,
While I am not fond of aluminum dome tweeters, their sound can be improved on by several methods. Before you go buying new drivers, you might try upgrading your crossover capacitors. By replacing the caps with high quality MIT, Zen, Harmony, or Solen caps, the treble balanace will not be changed, but the sound will be smoother. Another trick it to bypass the existing caps with .01mfd ultra high quality caps. Simply solder them in parallel with the existing caps. For more info goto http://www.northcreekmusic.com/Bypassing.html. The best place to obtain these capacitors is Madisound, Michael Pearcy, North Creek Music Systems, Zalytron, and Welborne Labs.
My experience is that most of the time the speaker is not the culprit when someone complains of harsh treble. Your room might be the real problem. Room treatments might be all you need. A combination of absorbing and diffusion materials placed in the right locations can work wonders for those high frequencies. Take a look at this website: http://www.audiophilia.com/hardware/echo.htm for info on Echo Busters.
Hope this helps.
Best Regards,
