Our most powerful 12" driver, featuring a patented variable density voicecoil as noted on the Supreme Series home page.  Where other drivers lose BL (force) during excursion in turn creating distortion, the RL-s12 maintains a constant BL, allowing for some of the cleanest low-frequencies ever produced by a subwoofer speaker.	MSRP: $799 each Single Price: $450 each Two or More: $410 each RL-s 12" S4 Set of Two                [ Click Images for Higher Resolution ]
Due to the nature of this product's variable density voicecoil, the T/S parameters will look a little strange when judged on a conventional basis. This is normal, the product being engineered for maximum sound quality in moderate to large sealed enclosures.
