but i find myself always adjusting the gain up and down its a Sunfire True Subwoofer MK IV have mains center and rears set at 90 hz as the sub as well should i open the hz on the sub all the way but it gets to boomy i like tight tight bass at lowest db.
Modern media is full of extra low frequency content. Making simple remote control subwoofer adjustments whether its the gain, on/off or customizable equalization preset adjustments have become a worthwhile advantage.
Unfortunately many consumer sub bass or subwoofer manufactures are a decade behind at including these affordable features. One brand your considering has gone so far as to call these adjustments "trickery."
Beware of non comparative fanboy advise or suggestions. All the best.
