Modifying Crossovers

"Why distort the signal through all that mumbo jumbo of wires and circuits?"

Why? Because full range drivers have their own shortcomings. Some people aren't bothered by them, others are.

What a ridiculous collection of statements. I wouldn't buy your speakers even if they weren't overpriced.

"I would be highly suspect of anyone who thinks they know more than the speaker designer. If they know so much, why haven't they designed their own speaker."

The original designed may have wanted to save money on cheaper parts, and as you've seen above, some have designed their own speakers.

My 2 cents...

And that's about what it's worth...

It is fairly well known that even in expensive speakers, there are crossover components that are not the best quality, usually because the company that is making the speaker is trying to keep a good profit margin. It is then tempting for an owner to see what improvements might be gained by swapping them out for better parts. On the other hand, a lot of owners don't do it because the warranty could be voided, and also if they try to resell them, the buyer won't want speakers that have been modified in any way.
