- Absolutely -- I have been getting along fine like this for months.
- I do want a bit of gain and am gonna add an op-amp "follower" (probably
- with a gain of 1.5 or 2.0) some day. Actually I am using a potentiometer
- (pair of `em) in a box that will someday be an active crossover.
- I want the extra gain, cause things just don't get loud enough for my
- taste -- even with things on full tilt.

- Perhaps -- but give it a try, you don't have a thing to loose and I
- can testify that it works.
