I've had these speakers for a few years and while I'm quite happy with them, I always felt they could be better, especially the top end.
Bass is good, not amazing but good, mids are OK (lacking a bit of articulation and clarity), trebles are OK but a bit harsh, fatiguing if volume is turned up. Also, I'd like to have more air.
The speakers are:
1x HiVi F6 6" Bass/Midrange
1x HiVi TN28 Fabric Dome Tweeter
2x HiVi M8a 8" Aluminum/Magnesium Woofer
The speakers are bi-wired and connected to a Micromega PW400 amp, cables are 10AWG BJC.
It's not easy to find better replacements for the top mount tweeters... so I'm considering several options:
First, I can't seem to find a way to move the pods. They seem to be fused to the cabinet somehow... Doesn't look like I'd be able to remove the tweeters either so I'll have to find a way to yank them out of the cabs. Once that's done:
1. Find other similar pods and install better tweeters in them (original specs are 1 1/8 soft dome, 6 Ohms, 40W, 88db, 2K/20K).
HELP: Any tweeter suggestions? Where can I find one that would fit these pods? Can I use 4 or 8 ohms instead of 6?
OR
2. Build/Buy a small cab or open baffle and use a better tweeter.
HELP: If I do this, I'm thinking of getting a ribbon tweeter. Any suggestions?
OR
3. Change the midwoofer (6 1/2, 8 Ohms, 45W, 88db, 42/4K) to a midrange driver (something like 100/12K) and use a Super Tweeter on top.
HELP: Would I need to change the crossovers? What Super tweeter would you recommend? Fostex?
OR
4. ???
The crossovers look simple... 2 coils, 1 47uf bipolar cap and 1 3.3Ohms 5W resistor. I was thinking about upgrading the cap and resistor. Can't hurt...
What do you guys think?
I've built several amps and a few other things but I lack experience with speaker builds/mods...
Thanks for your help and suggestions!!

4. What you may have here is the treble going wide on those pods at their low end, just like the woofers do as the baffle begins to look small. It may mean that your directivity varies like wide in the bass, to narrow in the midrange, wide in the lower treble and to narrow at the top. It ought to be a smooth transition. Not only could the pods be preventing this, there may be reflections off the top of the cabinet, which may explain some of the harshness.
From my research, it seems like the tweeter is just not great... And I guess the pod isn't helping.
So, what if I removed and replaced them with a better tweeter, similar specs, in a small cabinet, like the Denovo Audio Knock-Down MDF 0.04 cu. ft. Micro Bookshelf Speaker Cabinet?
