Am presently quite satisfied with a pair of REL Strata III’s, 100 watts each, 10 inch driver, rated to 18Hz (though when I tested them I got a response at 16Hz), made in the 1990’s.
They’re accurate with no muddy, sloppy boom.
It took a little while to find two good deals, but I eventually rounded up two for less than half the price of one new.
