Considering a Second Subwoofer for the Front

The recommendations are along my line of thought.  I want the sub to augment my sound.  The current ones are dialed down.  My bucket subs are home depot.  I intend to follow the advice of buying a second salk.  Thanks everyone.  Steve

I called my friend who recommended trying the bucket sub. The formula is on Bruce's website-Transcendent Sound.  The Bass picture is spot on.  The sub is essentially the bucket with concrete in the bottom and a woofer on the top.  I control mine with an amplifier that can cut off at various levels.  They augment the sound.  They are not meant for heavy bass.
