If you have facebook, there is a post here on our user's group's page that talks about a speaker we made used to research elephant communications,

A review with measurements and a longer post by Tom elsewhere on the speaker.

Tom, do you know the names of the researchers or studies that used this speaker?

Pretty much the whole of this thread has had me shouting 'NO!' at the designs...

Yes, i think so.
The researcher was a lady named Joyce Poole but the other person's name i don't recall, this was from Cornell university. I remember they published an article in National Geographic about their Elephant communication discovery in (I think) 1988.
Hope that helps
Tom

Until I read the weight I thought it's a toy...

I want to listen to it for a moment.
870 kg? I'm worried my manufactured home floors wouldn't handle the weight ???
Maybe I'd have to listen in mono. LOL

Speaker by Stig Carlsson. A smart design for damping reflections. Similar models I have heard. Sounded yummy.:D

Two 18 inches in each speaker. If you can include DIY in this thread? Maybe it's a little cheating? It's easy to go bat crazy with DIY, so to speak.:cool:

I think tweeter-woofer bookshelf design are like cars--it is the result of many decades of iteration that settled on a near optimal compromise. Sure, there are 6 wheeled cars, 3 wheeled cars, cars with rear wheel steering, all wheel drive, rear wheel drive, 2, 4, 6 seats, whatever.

But globally, most popular cars has four wheels, front wheel drive, four cylinder engine, in a two or 3 box configuration.

The research on sound reproduction says flat frequency response and wide directivity sounds the best, and it seems like 2-way bookshelf can deliver that at low cost.

Efficient? Yes. Boring? Yes.

Personally, I like boring and efficient. The most exotic thing I own is a Kinesis Advantage2 :)
And speaking of unusual designs, I will never forget the 1963 Amphicar 770.
