Had Three Different Speaker Thoughts; Now A Fourth

The fourth option a friend mentioned and it has appeal is this... I also own a pair of Polk RTiA7 towers. They are a really nice cabinet with a nice build that house a 6.5 and two 7 inch drivers and a tweeter. He said I should think about replacing the drivers with Scan Speaks and upgrading the crossovers.

I justt completed a new xover for my 15+ yr old Seas Thors,
MTM,
Had Hovland caps,
Went with a a;; Mundorf. High end
I found some gains in the Millennium tweeter (has 4 caps, = cost me a bundle) and for the dual W18E001’s, made some mod to the cap, went from the original 8.2uf Hovland>> to a Mundorf Silver Oil 8.2($150ish?/) and a Mundorf SESGO 2.2($100 each!!) The W18’s now have rock solid punchy bass.
The higher end Scanspeak 7 inches are super woofers, but quite the price.
So on the 7’s you havea choice
The Seas Graphene $500 each
Of
Scanspeaks many options, some go as high as $800 EACH!!!
Both labs offer incredible new midwoofer designs,
The Seas Graph has a titanium voice coil, which IMHO is the best bet for upper mids to say 1500hz.
For the tweeter section, I have no suggestions.

Thoughts?

Well, you’re considering a monitor with concentric dynamic drivers, a floorstander with a horn midrange, a quasi-ribbon dipole panel speaker, and a more conventional floorstander you already own but you’re gonna swap out drivers and somehow change the crossover.  So yeah, I have one overriding thought — what the hell are you even looking for???  I mean, you’re all over the map here sonically man!  What specific improvements are you looking for over your 606es, and what sound characteristics are most important to you?  Some kinda focus is needed here to make any meaningful recommendations.

soix makes a good point. Each of those speakers has its strong points. It depends on your priorities.

Fritz is a good recommendation.  All the drivers he uses are from Scanspeak.  Search this site for plenty of recommendations.

The Razz is a nice sounding dynamic speaker and will not be overkill for your room.  Your amplifier complements them perfectly.
They improve greatly over the current Klipsch Heritage sound because Volti has done an amazing job at controlling cabinet resonances.    

Replacing drivers and crossovers to an existing cabinet is not a trivial operation and will be more work than imagined, results are not guaranteed either- drivers are tuned to the cabinet specifically.  
Voicing crossovers is a science and an art and the heart of any speaker.  You need to know what you are doing to get the best sound.  

If you have the Razz in your sights I say go for them.  A better sounding speaker than any Klipsch heritage.  Dynamic, musical and exciting with plenty of detail.
