Gallo Reference 3.1 with/without the subwoofer amp


Does anyone have an opinion regarding the necessity for using the subwoofer amp with the Gallo Reference 3.1s?

i just got a pair and was suprised by the amount of bass they had wihout the sub amp (this is with less then 20 hours on them).
I've only heard this mentioned in passing in forums,
but I'd like to see if anyone can confirm this:

I have an ARC Classic 60 on 3.1s in a small room,
(not the highest current amp of all time) and contrary
to a vast majority of forum threads have way, way too
much bass.... So much so that during bass heavy
parts of songs especially at high levels, the mids
will smear and get lost.

Highs and mids sound great in parts of same songs
w/o low end info.

The SA was actually suggested to me as a way to
DECREASE bass, adding SS dampening to the slow
woofer. I'm hoping this will help the midrange mud
I have from time to time. I've tried a few resistors
across the second terminals ala 10 Audio but results
were dubious at best.
I think more than an amp/speaker interface issue, you have room problems that need to be solved. Sounds like you and/or the speakers are in a room reinforcing mode, most likely 80-100 Hz. I would try moving youself and the speakers around a bit. And some well placed tube traps will soak up some of those standing waves.
