SubWoofer Help ASAP...


Hello, can anyone recommend a solution. Just moved into a condo with carpet all over. I am currently running 2 M&K subs... MX-350 THX and MPS 5210 THX... Both are dual 12" drivers.

My problem is that the bass notes on both music and home theater sound very boomy and almost hollow in a sense. I had the same exact setup at my previous place and sounded amazing. Concrete floors on previous place. Oh yeah and new place, set up is in the second floor.

Question is what can I do to get that tight accurate bass that I had. Any help or suggestion welcomed. Thanks in advance guys.

Looking for the BASS

However, Bryon suggestions are very good and clear and pretty much cover the subject. I have but two minor comments, which I hope he does not mind and also agrees with them:

1) When applying "METHOD 1", it is helpful to play a jazz walking bass line (make a loop with the cd player if possible) and look for the position in the room where all notes of the double bass sound equally loud and tight. This is what Bryon means when he writes "listen for the location where the bass is the most *consistent* across low frequencies"

2) When applying "METHOD 2", at step 2) is the crossover frequency of the subwoofer, of course.

Finally, start with only one subwoofer. The second one you can place following the exact procedures outlined above.

Good luck and be patient!

It takes some time till one starts to hear the frequencies that are reinforced
or weakened by the room. This is why it takes time to set up decently a
subwoofer.

A pair of decent headphone, however, can solve this problem in no time. By
listening the selected walking bass (or bass solo) alternatively via the
headphones and via the speakers one can easily identify the artifacts
induced by the room, viz. what one hears in the headphones is not affected
by the room and consequently the bass is always tight and fast (no bloat).

To find a decent position for the subwoofer I play track 3 on Norah Jones'
"Come away with me" album, i.e. "Cold cold heart". I
make a look with my cd player and play only the first measure of the bass
line starting the song. The passage lasts 3-4 seconds and has only 6 notes
which are easy to follow but are sufficiently different frequency-wise.

To find tune the position of the sub I use a bass solo. Any will do. The one
suggested by Bryon is certainly good.

Hey Bryon,

Thanks for the suggestion. I am not very familiar with the music of Cassandra Wilson, which is yet another reason to buy the "New Moon Daughter" album.
