Listening Impressions

These have a lot of bass for their size. The voicing is about perfect, and they
image very well. They lend themselves well to extended listening sessions, as
they are very smooth and relaxed.  The B3N's handle the midrange duties

Woofer Porting  (added 2/08)

I would suggest the woofer enclosure be tuned to 30 Hz. A 1.5" port would be 6.5" long, and a 2" port (better) would be 12".
I always port out the back or bottom to minimize the extraneous port noise, so the bottom configuration would be optimal
with the 2" port. Alternately, you could add an elbow to
port out the back. If you use the smaller port, put it on the back up towards the top of the woofer enclosure.

Parts List

The lion's share of the parts can be procured from either Madisound or Parts Express. Eagle resistors, Madisound
inductors, and Bennic caps were used in the original design. I've noted acceptable PE subs should you choose to purchase
from a single vendor.
