I've got a pair of Rel Strata III's which I use with
Magnepan 1.6QR's. The Magnepans are notoriously difficult
to integrate well with subwoofer(s). The Rel has a
highly variable crossover, high & low inputs so it can
be used simultaneously with both music and HT systems,
and tuneful well-defined bass. They are no longer in
production and are highly sought after on the used market
(I had to import my second unit from a private owner in
the UK). Recently two showed up on Audiogon in the
<$1000 range. It's an excellent subwoofer.
