Desktop Bipole Concept: Fact or Fantasy?

[roadsterdriver]

I've bought some Fostex FF85Ks for the purpose of building desktop bipole speakers to go in my 6'X9' office.

There are two listening points: Directly in front of my computer monitor(ears above drivers) or about six feet back(ears below drivers).

I thought bipoles, with the second driver pointing upwards, would provide a wide possibility for good sound at different listening points and make a nice room filling sound at low volumes.

Do I have any grasp of reality?

Not sure if it'll work but I'd like to know if it does. I keep wondering what a double-stack uFonken might sound like. Mini-towers about as high as my 32" flatscreen would be cool...but would bipoles be good for watching movies in the bedroom?

well, I'd imagine they "technically" wouldn't qualify as "true" bipoles, but it certainly couldn't hurt to try

The CSS EL70 in "castle-tower" are a lot of fun, and the upward firing second driver gives a lot of placement flexibility in terms of side/rear boundary reflections. A pair in my wife's living room are approx 10ft apart and angled to an undamped rear wall. Compared to the previous Buschhorns with FE108EZ, I find the early reflections from this placement increases soundstage width and height, at the expense of depth and image specificity. In this particular application, that's hardly a detriment.

This will be boundary reinforcement like with an Allison model 4. Not a bipole. If you put it up right against the wall that is. Listening from fairly above them if on a desk, it will be beneficial to maybe tailor down the top speaker towards HF, if it is still hot enough at the given axis. A small inductor can help.
