@barcardi,
They both make great subs, but Rel subs do things that no other subs do and that is that they effect the whole spectrum. Highs, midrange and low end is effected. Scale and depth of soundstage is affected. And that’s something special as they specialize in just subs.....That is exactly how I feel about PSA subs and what their designer Tom Vodhanel does. That’s what I call ’voicing’. PSA does it, if not better than any other sub manufacturer for far less cost to the customer than REL or SVS. I’ve owned 4 different pairs of SVS subs and never liked any one of the models voicing. And Tom Vodhanel's PSA customer service is legendary. REL to me, is way overpriced, IMHO. The highest compliment I can give PSA subs is you can’t hear them. You only notice them when they are not on/playing.
