Thanks to Kuoppis I have discovered REL. Seems like I can buy 2x (as per above, I need AT LEAST, and a miltiplier of, 2!) REL G1 mk2s for about the price of 1 x Magico S-Sub. And if I ever decide I need more subterranean bass I can always double up on the G1s....
Given I am a bass-head, I am considering the end-game and cost-efficiency. Does anyone have any experience comparing 2x2 REL G1 mk2s to 2x Magic S-Subs?
