AIRMOTIV SPEAKERS

Switch Settings on the Airmotiv E2+

The Airmotiv E2+ surround sound speaker is extremely flexible. Each of the tweeters on the
Airmotiv E2+ may be individually configured to be in-phase or out-of-phase with the
midrange/woofer using the two small switches on the rear of the speaker. These switches ONLY
affect the phase of the tweeters.

The Airmotiv E2+ will provide the most precise sound imaging and localization when configured
as a conventional direct firing or "bipole" surround speaker, and this is what most modern
surround sound standards recommend. To configure the Airmotiv E2+ for this mode, simply set
both switches on each Airmotiv E2+ to IN-PHASE.
In some circumstances, especially in small rooms or when the surround speakers are very close to
the listener, you may find that sound originating from your E2+ surround speakers is too easy to
localize. If you prefer a more diffuse presentation, you may prefer one of the dipole configurations.
The dipole configurations produce sound which is more diffuse, where voices and individual
sounds tend to be difficult to localize, and which may sound more pleasing with certain surround
sound content - and more like typical room ambiance.
To configure a pair of your Airmotiv E2+ speakers to operate in dipole mode, set ONE of the
tweeter switches on each speaker of the pair to its OUT-OF-PHASE position. It is VERY important
when doing so to maintain left-right symmetry. This means that, if you're configuring your
surround speakers, you must either set both tweeters closest to the front of the room out-of-
phase, or set both tweeters closest to the back of the room out-of-phase, and not one of each.
Setting the rear-most tweeters on both surrounds out-of-phase will produce an effect typical of
most standard dipole speaker, while setting the front-most tweeters out-of-phase will produce a
slightly different effect. Neither setting is more correct, so choose the one that sounds best to you.
(If you're configuring rear surrounds mounted on your back wall, be sure that the two tweeters
closest to the center are set the same to maintain symmetry.)
The Airmotiv E2+ also has a third special mode; inverse bipole. That mode is configured by setting
both tweeters on each E2+ out-of-phase, and will produce a somewhat different effect, which you
may also wish to consider.
