REL Gibralter G2 a good choice?

Hi all,

I've been planning to add a subwoofer to my system (see below) for quite some time now. I would like to augment my monitors and am looking for "musical" bass rather than the Home theater version.

The REL line of subwoofers seem like a good bet, primarily as they have Speaker level connections. This would mean the monitors would run full range and the REL picks up from around 45 Hz or so. I realize this doesn't lighten the load on my amp but has the benefit of not adding extra equipment to my system. I was also looking at JL audio but my understanding is they work best with an external crossover with High pass/Low pass filter set up and I'm not sure the added cost and work is worth it.

The top contender at this time is the REL Gibralter G2.

I would love to hear your thoughts/comments.

Thanks for reading!
