Buddy of mine just picked up a pair of DQ-28 in great shape. One tweeter is under preforming. It works but does not have full range of highs. We swapped it with the working tweeter and it is NOT the crossover it is the tweeter. Has anyone tried ?? Are they any good? I see they have replacements available for $127ea. Should I replace with factory or do y¡¯all have a replacement recommendation? Thank you in advance for all the help. Cheers
