Good-day, My main amplifier has the cut off freq as the lowest possible to be 100hz, well my speakers are all capable of going to 40 with the two front mains able to reach 28hz. I am using the line levels out and have set all speakers to large as all bass drivers are 6+ inches or above. Is there ANY way I can get lower feq to be sent to my speakers besides the sub, which is 15 inch with a digital amp able to hit 400 watts easy. Thanks for any advice... :cool: [/FONT]
