q's about 2.3's with and w/o baffles

[happierears]

may need darque knight's help on this-would love to have his e-mail address.
need to know what is the difference in the 2.3's with and w/o baffles. more than just obvious conversation. lots of tech info.

[dorokusai]

What do you mean w/o baffles? without grills?

[hoosier21]

Mark

no obvious conversation

[dorokusai]

Oh, got ya' Hoosier.

Nevermind, good luck in your quest for information as I wouldn't want to waste your time w/ obvious conversation.

Good luck and happy listening.

I'm baffled :confused:

[happierears]

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. :eek: ?????????????:D anybody enthused yet!

[F1nut]

We call them donuts.

[happierears]

well...for all you techs out there...I need to know the difference in with and w/o donuts !!!:o

and where is the MARS Hotel located at ?

[F1nut]

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.

[happierears]

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:eek: 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? :confused: 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.

[hoosier21]

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

:cool: where did you get the info about midrange?? everything i've read and heard is about bass.....I have a newsletterabout donuts that say"the rifid disks are to extend the bass repsonse dynamics"...do you have any written info you could pass along?

[F1nut]

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?

Nothing written down, it was during a phone call
