Break in time: Pioneer SW-8MK2 Subwoofer?

100-200 hours should suffice.

I use a pair. I can't remember when they broke in.

Mt10425:
I started with a pair of the subs, which I found confusing, so in the interest of simplification, I unplugged one.

I've been trying to determine optimum placement and settings in my room, and so far have not found the sweet spots. :)

Where did you position your subs and what settings work best for you? 55 or 60 hz seems about right to me, with the volume knob about midway, depending on source material. With some acoustic jazz, the sub seems to fill the music out nicely without calling attention to itself. With material that is more bass heavy, such as reggae, r&b, and electronic, the sub often sounds too prominent. I've yet to experiment with large scale orchestral works.

I'm hoping I can eventually "set it and forget it," but this early in the game, I'm not sure the sub (s) are going to be an improvement.

Ps-

yes The REL is the best in the biz (when you are ready to step up)!

Now, back to your query- the Pioneer will start to break-in after 200 hrs. Keep me posted & Happy Listning!

Your room is small, and that makes it difficult to get a sub working properly. Try keeping it away from walls and corners. Start with low volumes relative to the main speakers and bring the subs up slowly. Some tweaks you may want to try are spiked feet, a separate crossover to filter out the lowest frequencies and stuff some kind of fabric into the port.
