attycda Posted November 30, 2022 Share Posted November 30, 2022 I'm asking a question because I don't know the answer. I know that there are woofers and subwoofers with the latter having a lower range. Suppose you have the speakers side by side... A Klipsch 10" woofer and a Klipsch 10" subwoofer. I assume that they're made differently and that they don't differ only by their respective crossovers sending signals to each. If they are different, how so?

Peter P. Posted December 2, 2022 Share Posted December 2, 2022 The subwoofer driver will have a speaker surround that permits greater excursion (say, 3/4" for a subwoofer vs. 1/2" for a typical driver although those are not real numbers). The greater travel is needed to move sufficient air at low frequencies. 1 1 Quote Link to comment Share on other sites More sharing options...
henry4841 Posted December 2, 2022 Share Posted December 2, 2022 And the larger the cone the more air you are going to move. 1 Quote Link to comment Share on other sites More sharing options...
Peter P. Posted December 3, 2022 Share Posted December 3, 2022 Another difference is obviously the subwoofer's dedicated amplifier. Reproducing low frequencies at the required levels to match the rest of the program material whether music or movies, requires more power than a typical amp delivers. That's why subwoofer amps typically have higher output ratings than stereo amps. 1 Quote Link to comment Share on other sites More sharing options...

I also have a pair of RF3 IIs which are nice, but I'm willing to experiment with them. The RF3 II's need bass. So I was exploring whether I could marry these two. Obviously I'd need an appropriate filter. If normal woofer frequencies are sent through a speaker with greater excursion, will it sound much different than one with less excursion?

The subwoofer driver's specifications may put limits on how high in frequency they can reproduce, independent of the cabinet they came out of or the amplifer attached to the cabinet. Therefore, they may not reproduce the same frequency range as a standard speaker's woofer, even though they may be the same size. Of course, the cabinet you re-mount the subwoofer driver in will have an effect on the speaker's performance, but most likely on the low end rather than the high end. So yes, they most likely will sound different. Quote Link to comment Share on other sites More sharing options...
billybob Posted December 3, 2022 Share Posted December 3, 2022 You should have plenty of bass with the 3s if they are six inches away from a back wall. They are rear ported. Quote Link to comment Share on other sites More sharing options...
billybob Posted December 3, 2022 Share Posted December 3, 2022 BTW, make certain the straps are connecting the hf to the lf on the biampable rear connection on rears of the 3s. Quote Link to comment Share on other sites More sharing options...
