I just finished installing the Seas ER18RNX's, replacing the Polyglasses in my doors.
I am extremely dissapointed. There is NO midbass output at all compared to the Polyglasses, even in a simple A/B comparison. Do these things need to break in? Is my door simply too much volume for the loose suspension of the Seas?
I have them installed in a FULLY deadened coupe door (bit bigger than sedan door). The only method air can escape is through the window crack. The speakers are mounted to 3 x 1/4th inches of MDF rings, with ensolite sandwiched between each layer. I am pushing ~ 150 watts @ 4 ohms to the Polyglasses, and ~ 75 watts @ 8 ohms to the Seas. I understand that the Seas need more power, but I am running into this even at comprable medium listening levels.
Any advice would be greatly appreciated, as I am very dissapointed right now.
