@tmsrdg Thanks for that info. Looking again on Madisound in the Clarity Cap MR 400V (is that enough voltage?), I can get to 28 uF with a 27 and 1 uF in parallel. For 14 uF I need the 12 uF and two 1 uF caps.But given that I already have the Clarit...

@dgarretson Thanks for the reply. So, are the CS2.4 values available to the public? I will contact Rob Gillum for more info.

@tomthiel Thanks for the clarification. This pichttp://www.hifishock.org/gallery/speakers/thiel/cs2-4se-2-thiel/shows "Jim Thiel Signature" versions SA 28uF 630V and SA 14uF 630V. I cannot see a 1uF cap in parallel. The values on the woofer sectio...

@dgarretson Owners of standard CS2.4 speakers may be interested to know that the only internal difference that makes a 2.4SE is the use of ClarityCap SA film capacitors. DIYers can make this upgrade or better by substituting the more recently... 
Speaker audition recommendations?
Vandy Treo CT would be on my my short list in this price range. I've only heard the non-CT version - and quite liked it. Made in US, too. I haven't heard the Persona line but not surprised you like them, based on drivers and technology (altho' I w... 
Ayre AX-5 Integrated Amplifier
Make sure to get an in-home trial with the Vandy amps before you part with your AX-5! Pretty short list, IMO, of amps (including separates) better than the AX-5.

Thanks for the post, TomI'm very excited to try cap upgrades. Without further information, I'll probably try the latest Clarity caps that will fit in the 2.4 enclosure (which I have yet to open). Probably try some Cardas solder. Probably be weeks ... 
Why so few speakers with Passive Radiators?
The 2Ce and 3A use sealed enclosures (I think the Treo has a downward firing port). From Tom Norton's 3A review in stereophile: A cutaway photo reveals four drivers and three separate sub-enclosures—the bottom of which is the largest, for the re...

Meanwhile, there is a pair of CS2.4s for sale, $1900, seller rates them 9/10. I kinda wish I had bought something like this and sent the crossovers to Rob Gillum for a full cap upgrade. This would probably result in SQ on par with anything new up ...

Note that the 2.4 SE only replaced two Solen mylar feed caps with Clarity SAs. Today there are much better caps available today from Clarity, Mundorf and other brands. My personal experience (via consulting for other brands) is that the upper ... 
Why so few speakers with Passive Radiators?
@jon_5912 that sounds right. From Richard Hardesty in APJ Vol. 3: Vented subwoofers offer inferior performance compared to sealed enclosure subwoofers of equivalent quality in the following areas: transient response, phase response, group delay,an... 
Why so few speakers with Passive Radiators?
I consider the passive radiator a special case of a vented design:1 Sealed enclosures2 Vented enclosures    2a Ported    2b Passive radiatorKeep in mind I'm just a bozo typing opinions on a forum, not an expert! 
Why so few speakers with Passive Radiators?
I agree that it is a "successful" trade-off and I am plenty happy with the bass performance of my CS2.4SE. But I think you need to directly compare sealed vs. vented (including passive radiator) designs to fully understand the what the trade-offs ... 
Why so few speakers with Passive Radiators?
Everything is a trade-off in speaker design. If there was one "right" way, all speakers would share that design! Each designer weighs the trade-offs to optimize what they think and feel sounds best.Sealed boxes tend to give the best definition and...

That "getting out of the way" quality of Thiels is awfully addictive.   Over the last 25 years, I’ve heard speakers from Wilson (W/P 7, W/P 8, Sasha, Maxx), TAD (Reference One and CR-1), Revel (M20, Studio, Salon Mk 2), Avalon (Eclipse, Ascent, ...
