    Upgrading crossover components of store-bought speakers.

    Has anyone ever successfully upgraded the components of a store bought speaker?

    The reason I ask is because the NHT SB-2's seem to use very good quality drivers...not entirely sure but the tweeter seems to be a Seas tweeter and im not too sure about the mid.

    The crossover itself appears to be made up of just 2 capacitors, 3 resistors and 2 almost microscopic inductors. One inductor an Iron core, the other is actually a relatively small air core inductor.

    So, instead of building a pair of DIY speakers for the PC, I thought it may make sense to take these SB-2s i have laying around and improve upon their already very decent performance.

    My guess is the standard dayton/solen caps would be a major upgrade from those currently found in the speaker. Mills resistors and maybe some 18ga perfect lay inductors would be cool as well... Anyone think this is worth doing? (assuming I can find the exact values of everythuing in the current crossover?)

    Be aware that changing inductors to ones with significantly different DC resistance will change the operation of the crossover.

          Small electrolytics can also have high ESR (series resistance) so keep that in mind if you the stock caps aren't film caps. I've modified B&W and Monitor Audio speakers that needed extra padding on the tweeter level after the caps were replaced.

            Wow, those "hi-end" companies are using electrolytics in tweeter circuits!?? :gah:
