    Default baffles..

    if baffles is not the correct term...here is what is in the literature from December 1988 High Performance Review on the Polk website from 1995::
    "two of the 6.5-inch bass/midrange drivers are mass-loaded (with a rigid disk) to extend their response down into the lower bass range."
    the next year they removed the disked speakers because they changed the inside workings. ?????????????:D anybody enthused yet!

    Are you asking if regular drivers can be used instead of the "donut" drivers or what?

    He may be asking for the differences in sound, when listening to the donut version and the donut free versions. I think there was a donut-free run first, then some donuts for a brief period of time, followed by the donut-free tls, maybe? Or was there a run of donut free jobbies just prior to the tls also? I don't know, but perhaps he'd like a run-down on the differences in sound between the various 2.3 jobbies.

    loud and clear heard me loud and clear (except I'm a she:p ) thats exactly part of what I what to know,exactly. I want to know why---the differences in what they were trying to acheive--were the components inside the speakers the same-- could the donuts be replaced with non-donut speakers--wonder how much that would change wondering most about the components. what would be the difference in regular ones and TLs. how would you tell if you had TLs or not TLs? DUH? who would know the most about this stuff? would love to know the exact techs.

    Hi Happierears! Welcome to the Club Polk Forum. The donut is on the low bass woofer as a weight. It help the speaker reach lower frequency levels. The "newer" woofer in the TL model is a different driver. I don't know how well in would work in the SRS-SDA version since the crossover is very different.

    I don't have the exact specs.

    When I had a pair of the 2.3s I asked Polk's customer service "why"

    They felt the speaker had too much midrangs, they added the dounuts to slow the driver down and reduce the mids

    later versions of the 2.3 corrected this and did not have the dounuts, then Polk revised that model to the 2.3tl

    If you have the dounuts, you do not have the 2.3tl

    They added the donuts to tame too much midrange. By adding the donuts and therefore reducing the midrange, the two drivers in question became bass drivers due to the limited frequency response. Clear enough?
