Have you guys ever considered moving the bass driver from the bottom to the top?

Just curious

    I've never thought of it. Should be simple enough to test out. Flipping the entire speaker upside down and swapping the L and R should produce the same effect as swapping the connections to the crossover.

    Report back with your results if you decide to try it

    Trey, kind of off topic, but what do you think about making an internal "point to point" crossover for the LSi9 and bypassing the big 260 cap?

    i think this speaker could be awesome as a straight two way that bottom midbass just tries to do way to much which leads to atonal bass and muddy midrange... Imo

    Conrad - would you be down for a listening session tomorrow if you are free?

    I would like someone with some LSi9 speakers as well to bring em over to A/B...

    Thoughts?

    It would be even more difficult to drive too.

    Want to design a new x-over, this should get you started.

    I am no crossover designer - I just like to mess around with stuff!

    Depending on what Polk designed the optimum listening axis to be.It's possible that swapping positions may be benifiicial if it then puts your ears closer to the optimum axis.

    I don't have the schematic but I assume the 260uf is in the shunt position in the lowpass section of the bass only driver?If so removing the cap will mean the bass only drivers output level will increase and overlap the output of the midbass driver over a greater range.The result would likely be an excess and further thickening of the midbass and lower midrange.

    Fred, I believe he means bypassing the electrolytic cap with a film cap.

    Doh:redface:.Thanks Mike.Bypassing and removing are entirely different things are'nt they.But in that case I would not expect anything transformational.

    Yeah I think we should just plug the amp straight into the drivers! :)

    I did it to my LSi25s when I did my crossover mods and I don't regret it a bit. My ears are a lot closer to the plane of the lower drivers, so having the midrange there makes more sense.
