Question about bass extension & blending w/ sub

[Grandpaw]

Bingo!

The signal goes both to the amp and to the powered sub. This way, there is no degradation of signal by routing it through the sub's suspect crossover before it hits the mains. Easy to do and you'll enjoy far better sound.

I have been asking questions and I am learning about this same subject so go easy on me.

I was told to go from the pre outs of my amp to the line in of the sub and then from the line out of the sub back to the main in of the amp. This will allow the signal to go to the sub first and the sub would remove what it was going to play and the remainder of the frequency's would then be sent to the main in terminals on the amp. This would allow the powered sub for the lower frequency's and the amp would provide the power for the rest of the signal going to the main speakers.

This would put only the signal that each speaker needed to play going to where it needed to go. Each speaker would have all the power going to it to produce only the frequency's that speaker was concentrating on.

The articles that I have read say to send only the signal to each speaker that you want it to play. Seems like the way you are saying to hook it up would send everything to the mains causing them to handle the lower end that would be better suited going only to the sub.

I am trying to learn all I can about this and don't understand your train of thought. Why would you send something to the mains that the sub would do a better job playing. Help me to understand your method, Jeff
