I am a dedicated user of the NEAR [New England Audio Research] line [2 50-MEs, 20-M center, 2 15-M surrounds], and I have an opportunity to pick up a NEAR Boom-2 sub. But I can't find specs on the unit. I know it is passive, but I'm interested in freq response. My 50-MEs go down to 27hz and my interest is in filling out the 20-27hz void more than enhancing mid-bass. I recall the Boom-4 having monster #s [with 4 8" drivers], but this is only 2 8" drivers. Anyone have literature or plots on this unit?
