Those would get an all-billet baffle and side mounted PRs.Don't take experimental gene therapies from known eugenicists.

Yep, I don't think Polk will bring them back and take them to the next level.
An integral mounted RDO tweeter would be the show-stopper.

And the rear PR? -
You could mount them on their sides facing each other. Would allow you to place closer to the wall.Don't take experimental gene therapies from known eugenicists.

@xschop I need all billet shafts for my 47 RE build for my old Dodge Cummins 2500.
-
And if the PR faced each other they would cancel each other out right?

I don't believe those lower freq. would cancel each other. Many newer monitors have the PRs on their sides.Don't take experimental gene therapies from known eugenicists. -
If you sat perfectly centered between the speakers, it would actually be constructive interference. Bass frequencies are pretty omnidirectional though.
Interesting experiment for someone with 2 subwoofers would be to set one at 180deg phase setting and sit in between them and see what happens.George / NJ

Well with car subwoofers in those isoberic boxes or whatever I was told when they face the subs at each other they run one out of phase from the other. Take that with a grain of salt though. That's just what I remember.
-
I can say this now that I remember. My JBL L7's are run in phase and face each other and have tremendous bass. Just looked and my AR-9"s are wired same way. In phase, all four woofers.

Thought you still had those AR9's

An isobaric sub has the two driver mounted facing each other and out of phase. That increases the output since the drivers are working as one. This was a dual band pass isobaric I built many years ago.
