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.
How do they sound as they are. I would buy them thinking no crossover upgrade was needed or I just wouldn't buy em.
You might contact High Emotion Audio, they have crossovers and also Pipedreams.
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.
