I too would be interested in such "upgrades" but would like to hear for any Axiom staff on their comments.
Thanks

Nathan,
I would recommend contacting Axiom directly, either by phone or email (I'm sure they don't see every post on the forum, so you can be sure to get an answer that way).

As I'm thinking of the new Outdoor speakers I've also asked Axiom there "official" position on the tweeter upgrade discussed above (in case I can save on the shipping to Oz!!!)

A buddy of mine acquired a pair of Klipsch bookshelves and kept complaining about the shrillness of his horns. One day we decided to experiment with silk and cotton placed in front of his horns. When we hung a few pieces of cotton cloth in front of the horns, the sound became very acceptable.

Got to love the WWW for collaboration:
1) Trent from Axiom replied saying that knocking down the trebble helps tame problems he has one with particular recording.
2) I use JRMC for my HTPC software (it is very very good) and amoung the many features it has an EQ setting that one of the user/devs have then made a plug in that lets you assign custom EQ settings to different tracks in your DB. I've created a custom EQ Setting I caled "Sibilance Correction" that I can then apply to offending tracks...EG. I've found that Infernal's "Paris to Berlin" hisses like a snake but the following setting helps reduce that (I'm happy to experiment with other band changes should there be any suggestions)!



This (hopefully) means that I can target the offending recordings rather than making a global setting change OR permanent HW mods!

Thanks
Nathan

Nathan, fortunately I don't have those problems with the classical CDs that I own, but in the past I experimented with some pop CDs borrowed from the library. This was in response to posts here about "harsh", "bright" etc. Axiom speakers when playing supposedly "well-recorded" items. My finding was that they were by no means well-recorded and seemed to have a boosted response in the upper mid-range/lower treble, possibly to sound more impressive on mediocre equipment. Since one of my receivers has tone controls with variable frequencies, I experimented a bit and found that cutting 4-5dB at the 3KHz or 6KHz points improved things. So, at least on those particular recordings the offending frequencies were a little lower than the 12KHz area shown on your example.

Yes, I certainly wouldn't suggest making some tweak to the speakers which would have a universal effect.

that tweeter has a 10 watt 15 watt max which would be to low if you like to turn it way up like me,the dayton dc25ts-8 looks like the tweeter on the axioms it's the same size and looks just like it,and it's rated at 50 watts 75 max ,i was looking at the silk ones the other day but the diferent size turned me off ,don't want to router my m80's

How loud is too loud for those tweeters? The difference between them and the daytons (or any other tweeter for that matter) seems quite extreme. I don't listen to things very loudly so I'm wondering if they would work for me(my receiver, a panasonic XR-55 only gets to -20 very rarely)

These tweaters have similar specs to the dayton ones (the daytons do look almost identical to the axioms. I wonder if they're really the same)and they look as though they would be compatible. They look a bit cheap though. It's strange to me that those Usher tweeters have such low power restraints.

well i just started reading about building speakers and wow ,there is alot going on there .picking quality drivers is the easy part if you research online but the realllll problem is the crossover that controls the speaker .so to try and change the tweeter with out know the crossover would not be a good idea.each driver or tweeter has good and bad traits and the crossover compensates for that and a lot of other things.
