Subwoofer for Harbeth M30?

Will the use of a Bryston 10B active crossover improve subwoofer integration between the Harbeth Monitor 30s and a Rel active subwoofer?

Hi Chazzbo, Thanks for the advice. I guess that this is going to require some playing around, isn't it?

Thanks guys. Actually, I'll be receiving the M30s next week. I'm really looking forward to hearing this Harbeth midrange magic that everyone's talking about, but after the magic has worn off a bit, I will be looking for some bottom extension.... not a lot. Just enought to add a little more weight to the music. I look forward to hearing more from any Harbeth owner that has the time to share there experience in this area. Thanks!

Anybody ever consider using the Vandersteen 2Wq subwoofer. The propaganda that I've read suggests that they'll integrate seemlessly with just about anything.... including my ex mother-in-law. Anyone have any experiences that they'd like to share. By the way, I'm referring to experiences with the subwoofer.

Darn! I messed up that joke. I meant that they'll mate well with anything, including my ex mother-in-law. oh well.

I got my M30s today, hooked them up and listened to them for about an hour. Right off the bat, I'll tell you they seem to be cleaner than my B&W 801 Series III, but so far they seem less extended in the highs. Time will tell.
