Guys,
Keep in mind that I was talking about a -3dB point around 80Hz. That along with a crossover point of 80Hz would give you a pretty steep rolloff. I still prefer a flat response down to 40-50Hz for my own use, but I can accomodate larger speakers than many people out there. Hence the question about going with an F3 around 80Hz. I'd rather have a 60Hz crossover point as well but, again, this may not work for a lot of people.
The biggest issue I've found with smaller speakers is that more and more houses these days are built with large open floor plans and small monitors just end up lacking in the midbass area, making it difficult to blend well with a subwoofer. For this reason, I'm really leaning towards relatively small 3-way towers with multiple bass drivers to increase efficiency and dynamic capabilities. Powered towers might even be a possiblity, but that really starts to get expensive.
Otto, you really need to get the parameters of the driver to build a new enclosure around them. And yes, it's possible you could do better with new drivers. Either way, I'd be happy to help you design something when you are ready.
Also, the pic of those guitars got me thinking. I'm a rock fan first and foremost, putting a high priority on dynamics, but still like an accurate speaker that really brings the music to life. Maybe a line of speakers with some of those wild style finishes would be a hit with the rock fans out there like myself. Surely there's still plenty of us out there, right?
Sonnie, I've never really contemplated ribbon midpanels or tweeters. I've heard a few that sounded nice, but nothing that really wowed me. But then again I've only heard a few. Also, I've heard that some of the ribbons can be very fragile and I'm just not sure that I want to deal with those issues. I'd sure hate to have a customer end up with problems due to a faulty ribbon right out of the box.
