Pipedream speakers-crossover


I have been offered to buy a pair of Pipedream speakers with 18 tweeters and 9 mids per side, the owner claims that the speakers do need a new crossover. The speakers are an early model and a new crossover should be a major upgrade. Is anyone out there that can help me with the layout and parts for updated crossover.

Pipedreams have a crossover built in the speaker for the mid/tweeter panel.An active crossover is only required when you're driving passive subwoofers.
You might contact High Emotion Audio, they have crossovers and also Pipedreams.
How do they sound as they are. I would buy them thinking no crossover upgrade was needed or I just wouldn't buy em.
