Is there an advantage to an 8" woofer over a 6.5" when using a sub? I'm leaning towards an Acoustech PL-76 but am concerned about the woofer size. I also have a PL200 as a sub. I'm replacing an old set of Klipsch 5.5 monsters with 2 10" woofers. Klipsch is too big for the room and a little harsh at times with music. I was told when I called BIC that the Acoustech horn is warmer sounding than a Klipsch. So all that's left is to figure out which size wink.gif

Going to larger drivers can have various benefits not all of which are geared towards bass extension. Larger drivers can have lower distortion at the same frequency due to the fact that it displaces more air more easily. Also larger drivers can be made to have slighly higher sensitivity while maintaining similar extension.

Any thoughts on the difference in tone between the horns?

That depends on the crossover frequency from the woofer to the tweeter. I wouldn't take an eight higher than 2kHz., above that it will beam.
A better question is why get a tower that goes to 30Hz if you're not going to run it below 80Hz? A 2 x 6.5 bookshelf will work just as well in the frequency range you're using for.

And what did you expect them to say, that Klipsch is better? wink.gif

I keep bouncing between the PL horn series and the DV dome. I just want to be sure that I get clear highs and the full range of sound. As far as the horn comment from BIC, that's what I was expecting to hear from them. I have the DV62si bookshelf but it's missing "something." That's why I'm leaning towards the tower.

It's a $120 per pair speaker. It should be missing something. rolleyes.gif

Probably not, as long as the crossover is high enough, 60 Hz or higher.

You don't know unless you try. I tried... Still looking and trying to get as much information as possible about different speakers.

If by try, you mean listening tests in your listening room, that's not always the case. Of all kinds of speakers, subwoofers are the most likely to be accurately predictable from the right technical information.

The DV62si, in it's stock form has little warmth. It's tonally imbalanced. I think BIC purposely made them that way for two reasons, one to work as a surround and two, so it would not compete with the more expensive offerings.
