Which SPEAKER for the 21ST century?

Tweekerman, I agree with every point you brought up. Lobing effects and the space required for driver integration are problematic. I still think the manger will still need supporting drivers and may not have as desirable dispersion characteristics as some of the alternate single source drivers. At the sake of being redundant I am hoping that (untill the ideal driver comes to being) digital cross overs fullfill thier promise.

digital xovers should offer drivers their full potential..i hope thats in the near future..the MANGER is the ideal single source driver..all you need to do is add a FOCAL 10 or 11 inch or SCANSPEAK 10 inch woofer..i can not imagine a better set up for "any" amount of money than a FOCAL 11WX + MANGER..."is the ideal" because this driver delivers 90% of the frequencies with a fidelity like no other....this driver may not offer the "thrills and chills" of the new tech ribbons but are these ribbons revealing with true fidelity or with a tad of exaggeration?

Tweekerman, I am saving up to get a set of manger drivers. I plan to try different low end extension techniques, to see how low it can actually go, with help. If you look at the response chart, it seems to go to 60Hz at the same relative db as it has in the midrange, with a small rise at the midbass area. The fly in the ointment is the 88Hz resonant freq., but I have a trick or two up my sleeve for that. My goal would be to get 40Hz out of it, before any significant rolloff. This way, even if it is 12db down at 20Hz, you are still only 6db down at 30Hz and that's ok with me. It may take awhile to save up the cash,though.

As impressive as the Manger appears I am still not convinced that a Walsh type driver wouldn't be a better starting point to developing a perfect driver. The manger appears to be able to radiate either horizontaly or verticaly, but not both. A Walsh type driver which can lend itself to more seperation from its baffle appears to be able to be a true omni-directional driver(simultaneously horizontial and verticaly). As such it would be more practical in a surround sound system where the differences from side wall and rear wall would be negated. It would free the listener from a static position. Allow more individuals a larger slice of the "sweet" spot. Have more commercial applications in amplified concerts,theatre events, dance music and even (dare I say it ) muzak.

Twl i know very little on the tech side of speakers..you may however want to e-mail someone your questions about the potential of the manger..i've heard the driver only works in a woofer set up..i have a choice of 2 FOCAL woofers with the manger..
