By Jove, I think he's got it!
Only what you should do is add 3 subs to your REL to make 4. The number of subs is far more important than what kind. I thought, according to the research, each additional sub adds proportionately less. So my plan was to build 4 to replace my one Talon Roc, which would then be sold. My plan was going fine. Removed the Roc from the room, put the 4 subs in, heard the vast improvement.
But then before selling the Roc I thought what it would be like, put it back in, and there it stays! Either it was more than the predicted 25% improvement, or 25% is more than you'd think. Either way it was big enough to keep me running 5. Granted the Roc is two 12" monster magnet woofers in a ported isobaric cabinet. A much better quality sub than the ones I built. So quality does count for something. But numbers count even more.
