- The REL is a true sealed design (6.5 inch, Speakon High-Level input wired off the amp terminals) for tight, fast, musical bass in a small room
- Correction: the Wharfedale WH-D8 is a VENTED (bass-reflex) 8 inch, not sealed — more output and depth but less of the sealed tight character
- REL is pricier (~CHF 469-490 at Swiss hi-fi shops) vs the WH-D8 (~CHF 220-260 at Digitec/Galaxus)
- Caveat: the REL T-Zero MKIII shows a Final Sale label on rel.net, so it may be getting phased out and stock could be limited
- Brand-matching the sub to the speakers is irrelevant below the ~80 Hz crossover
