So originally I thought I had found an improved setup for the subs by replacing them with Kicker 4” 2ohm 2 ways by removing the tweeter bridge and using the full range as the sub. See below if you want the original post
My Solution to the Subwoofer Problem
The problem is that after only a few months I blew the speakers. This I started my search again for replacement speakers. I read on the forum that Madisound had a good selection I searched and found these
SB Acoustics SB12PFC25-04, 4" reed cone mid-bass- 4 ohms
These are 4-ohm speakers. They run about $25. They also offer a ceramic cone version for $65 but since I’ve become Formula 1 pit stop fast at removing the driver side rear panel I figured I try the cheaper ones first.
After yanking the old ones out I removed the two pieces of foam batting and then, taking an old pillow, moderately filled the entire sub enclosure with it.
I then installed the new speakers and tested them. These speakers (and the Kickers and the factory speakers) have to generate a lot of motion to produce sound so I decided to experiment with the factory foam material I removed from the sub enclosure and rolled it up and closed the port of the enclosure by “screwing” the rolled foam cylinder into the port, thereby making the ported enclosure a sealed one.
I tested it again and feel like the bass is much better. The bass is better but your expectations have to be tempered by what the unit is capable of. The sound is there but not the rumble of the bass.
I have an Apline iLX-207 and it has a built in crossover. I turned the subwoofer option to “on” and set the cutoff at 40Hz with a 12 dB/octave drop.
Being that these are 4ohm speakers they are not to work as hard as a 2-ohm speaker and if they don’t blow them I am going to say it’s the final chapter in this book. The only other option would be to upgrade to the ceramic cone versions if these don’t last but the paper and reed blended cone seem to be stout enough to handle the demand.
