If it is HT output you seek, any reason are you not getting ported subs?
The REL is a much prettier sub, but at $3.3k, you could get dual SB3000s for $2.3k. Dual subs are much more adapt at providing even coverage across several seats.
For HT output, consider dual, ported, PC2000 Pros at $2.1k. They take about the same floor space as the REL or SB options. See pic from my HT for how they look.
