Heya,

i was reading an article of Gary Biggs in the new CA&E where he says how he mounted his JBL splits facing 90° to his doors as they have a 30° off axis response.
Now, I know he knows what he is talking about, being a 7 time world champion on the SQ circuit, so was wondering if anyone knew the off-axis response of the Polk Momo's?

I checked the manual and the specs, but cannot see anything regarding this.

I am not sure if they do not have one (ie, face the speakers towards the listener) or if they have just omitted it from the specs.

thanks in advance
Bryan

    Send POLK AUDIO support a email and they will send you the information you need to help make your decision. I decided to angle my SR5250's in a bit instead of the flat mounting. If you are using the SR6500's they come with a coxial angle mounting post that the 5250's do not have. This will put your tweeter more on axis.

    I cant speak for the Momos but I can assure you the SR5250's will work just fine 45 degrees off axis. I broke out my trusty SPL meter and test tone CD and measured the left mid. It played up to 5 KHz before it rolled off 3db.

    The tweeters however are a lot more directional. They work better on axis.

    thanks, guys, only saw this now.

    I am going to try the tweeter on axis, and the mid about 15° off-axis, and see how that works. Will let you know as a matter of interest.

    Off axis is a good way to tame a bright tweeter - but a good on-axis tweeter is hard to beat sometimes.
