Infinity Interlude towers...non powered....

The beta 50 uses a film cap to cross the tweeter over, the il 40 uses an electrolytic cap to cross the tweeter over, that will be the only difference in their crossovers, the il 40's tweeter is a little dull sounding compared to the beta 50, if you replace the cap in the crossover on the il 40 with the same brand cap the beta 50 uses (bennic PMT 6.8 uf) they will sound very close.

Was is the degree of difficulty replacing the Caps?...I was thinking Solen...however...this involves some level of expertise...not my strongest asset...and i dont recall the Beta having particularly a better tweeter...in fact...i think the IL 40 is a vastly superior speaker...even with a slightly mellow top end...very well balanced, seamless, refined sound for for the money...
