[QUOTE="RobGMN, post: 8753720, member: 683408"] Very long. Read most. What are the Thiele-Small parameters of each sub? Your new sub may not be as good a "fit" for the box that your old one was. Are the old and the new subs the same impedance? Makes a difference. Do they have the same sensitivity? A 3dB difference in sensitivity translates to a doubling (or halving) of necessary power. If your new sub is much less sensitive, it will need a LOT more power to sound the same as the old. Passive converters can and do fail (been there, done that). Swap it for a known good one. Capacitor banks are good for tone sweeps, but you shouldn't need one to get a good solid music hit from your sub. Focus on the hardware you currently have and diagnose each piece as good before you add more to the mix. Troubleshooting is often finding a whole lot of good factors until you find the bad one.
