I have just received my new Klipsch RW12D sub and originally I was going to replace my current Pioneer SW-8MK2 sub.

Would it be advisable to use both subs at the same time considering they are mismatched? IF so what would be the best way. I have a Onkyo Tx-NR818 that uses Audyssey MultEQ XT32

Using 2 subs is almost always better than using 1. You can place them anywhere. Just not really close to each other.

The small sub may not keep up with the larger one. Set the large one further away and integrate it with the mains. Then level match the smaller one in a nearfield location to match the larger one with an spl meter. Eventually sell the small one and get another 12 in sub.

I agree with Derrick about the smaller sub. You can experiment by connecting both to your Onkyo and level match them at 75db when running Audyssey.

Thank you for the info.


Sorry for newbie questions. What is a "nearfield location"?

So are you suggesting setting the RW12D furthest from the listening area and the smaller sub near the listening position?

Also, if this was your equipment would you use both or just use the 1 RW12D? Room is 20x15x9.

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 100

example of Nearfield located velodyne sub and left surround - a speaker close to your field of listening. I would retire the small sub and budget for another RW12D. You would have an easier time of pressurizing the room with 2 12 inch subs. Do you have a picture of your room?
