Most if not all drivers shown here are oval and probably their sound do not differ much form a circular driver :

An elliptical driver is a quite different kind of beast, maybe not pure high fidelity, but with an appealing sound :

This is what I remember from my beginnings in audio reproduction and one of my current projects is to build decent boxes for Grundig elliptical drivers (Qts about 1.0) extracted from an old TV set, just to hear what was the sonic potential of what we use to hear in the good old days.

I made LTspiceIV simulations for various Tangband oval speakers. Including a satellite + subwoofer combination using active filtering. Interesting results. See attached .zip.

Hi there: Parts Express list a line of dual cone speakers on page 31 of their 5/1-6/30/10 flyer with 4x6, 5x7, 6x9 drivers, yes these are intended for automotive applications, however, you can always try them out for your application. ...regards, Michael

Updated and optimized LTspiceIV simulation results for a 2.1 or 2.2 active speaker system bi-amplified with a simple active crossover. Interesting results. See attached .zip.

personally im disapointed in the lack of GOOD elliptical drivers out there. Hifi never seems to have gotten over the 'cheap' image of ellipticals.....pity really since they dont suffer to the same extent as 'conventional' drivers, with cone quadrant resonance(or whatever the real term is called) or the dreaded bell modes...

New optimization using LTspiceIV simulation. Subwoofer acoustic response is now a flat top bandpass. Satellite high-pass filter is now more efficient. Overall response delivers 45Hz at -3dB. Nice and clean. Next stage will be sketching the box volumes (are the volumes practical ?) and the vent size (is the vent size practical ?)
