S280-6-283N it is a custom version off-shelf Accuton woofer S280-6-282, which has an advanced motor due to an additional neodymium magnet on the pole piece. This upgrade let to increase sensitivity and significantly reduce nonlinear distortion.
S280-6-283N - one of the best woofers I had ever to work with and, perhaps, the best one ever created by Accuton company. Fast, precise, structured and clear bass. I love it very much.
I would rate it at 5*, if it didn't have such a ridiculous price - around $1530. So, only 3*...
