Our community has rated this post as helpful. If you agree, why not thank Zorba1446

meh, if going with Klipsch for a sub I'd recommend waiting for the RP sub of your choice to go on sale (RP1000, RP1200, RP1400, or RP1600) from Adorama. These R series Klipsch subs have a long history of premature amp failures. Klipsch is pretty good about honoring their warranty but why take the chance of going through all that hassle?

Might be better off going with the RSL 10e for $300.
Very similar performance with a smaller footprint.
This may be better for a larger environment though.

Can't go wrong with either, both are good entry/budget level subs.

Notorious for amp issues. Scrounge up another 70-100 bucks for the Reference Premier 10" when it goes on sale (if you have the space for it and don't have/care about neighbors).

Picked this up earlier today, open box - excellent condition for $318. Hooked it up for my parent's karaoke set up and it sounds great. I had to turn down the gain so it didn't shake their house too much. Great find. Thanks OP

Amp failures are well documented. A better value option is RSL. https://rslspeakers.com/
