## Questions & Answers

**Q: Can this be used with downfiring sub?**
A: Yes.  I use it with a REL T9/i
Works a treat.

**Q: My downstairs neightbours complain about the bass on my onkyo subwoofer. Will this help eleminate the sound to them if placed underneath?**
A: It definitely won't eliminate the sound, but it might help, depending on which sub you have.  A downfiring sub may be the worse, front firing shouldn't aim at the walls/corners.. You might have a setting on your AV amp to EQ sound depending on the time of day, my Denon has Daytime/Evening/Midnight mode which curtails it somewhat

**Q: what is it's weight capability?**
A: Mine houses a very heavy 18" sub in a box which is 5" wider than the Auralex, - not sure how heavy my sub is (25kg maybe), but the Auralex copes no problem

**Q: can I put on that XT8F ?**
A: I can't see a reason why not.  You can buy pads for floorstanders in pairs. Maybe a more economical option with the same results.
