Has anybody had experience with Tantalum electrolytic capacitors ?

And would moving the bass crossover on the 3.6 ( or other models )
up to the chamber of the passive radiator have any effect ?

Thanks
Rob

Rob - I knew Tantalums from Bryston's 1980s designs, and checked them out. Not as good as our stock caps. Bryston abandoned them also.
Taking the woofer XO closer to the midrange driver would not be good.Some models would benefit from moving the XO to the cabinet floor, but the bottom is glued in. I've been running around this bush quite a bit. I will say that outboarding the crossover is having wonderful results. In addition to the gain in distance from drivers, add absence of vibration and freedom to mount components in free air, and lower ambient temperature for XO and for drivers, since the XO itself generates heat.

Thanks Tom
I am have a hard time finding " replacements " for the Topmay caps ,
I found AVS makes tantalums in the values needed and the are low 
ERS , so I was just wondering .
We talked about using 4 100uf

4 @ 100uF is what Jim always used. People here have recommended Mundorf's lytics. Or ask Jeff at Sonic Craft.

Many thanks for all the responses towards my 3.6 XO project. This is proving to be such fun already and so glad to have the history along the way! With regard to the Claritycaps: I see 250v and 630v option. I know that the 8.2uf version will be used as recommended by Tomthiel however, I can't seem to find 630v versons of some of the remaining ELs if required. The original Solen VersaTronics are rated at 400v so I'm a little stumpted here. I'm checking out Madisound and Partsconnexion for all components. Any other referrals would be greatly appreciated.
