For smaller units one could consider putting an ASC Subtrap (or similar devices) under it which can tighten the mid-bass. It works very well for my R205
REL Magic
I have to report this finding as a breakthrough to a new plateau. For the past four years, I have been running two REL Strata III's, one behind each Maggie 3.6R. RELs have always been known for their hook up at the speaker outputs. By this method of integration, REL boasts that their subs somehow lift the entire system. I have always felt this to be true, especially with one for each amp.
But now, I have just completed DIY signal cables for each sub using the same Neutrik connectors into the subs. I used some 16-gauge OCC copper wire by Furutech in the same terminal scheme as the stock cords. As expected, the bass notes are more extended and better defined, but this phenomenon of improving the whole presentation has also appeared again as even more impressive. Everything across the soundscape is just a bit more sweet and clear. If you have not upgraded your REL signal cables, please do.
