Deal Details
Easily destroys any sub by the likes of REL or SVS at *any* price. (Perhaps a too-low bar, haha.)

This is strictly for hard-core bassheads free from WAF constraints that are willing to shell out the dough but want a relatively small width/depth footprint (18 x 18").

For the rest of us, it's just nice to dream! 😍
  • Dr. Hsu is back with his ultimate breakthrough creation—a seriously powerful dual 15" subwoofer that turns from sealed to ported with the addition of a supercharger (SC). It's the world's first ever supercharged dual 15" ported subwoofer.
  • 1200W RMS drives dual 15" side-firing woofers for unmatched power
  • Modular design – Upgrade the standalone sealed D15-Chimera to a ported sub by adding the Supercharger (SC)
  • Easier to handle – this two-piece system is the only super powerful subwoofer on the market that is simple to install and move. This is especially useful for basement or 2nd-floor installations.
  • Beast Mode performance – 3-port option delivers ultra-deep bass with less port noise than dual TN1s, while matching their performance in 2- and 4-port modes.
  • Customizable port direction – Choose forward-facing ports for a bold look, or rear-facing to fire toward the wall and keep them hidden. We personally love facing the ports into the room - we think it looks cool!
  • High-performance specs – dual 15" side-firing woofers and 1200W RMS power
  • Features balanced XLR, unbalanced RCA and high level inputs for greater flexibility.
  • Balanced XLR inputs protect against noise caused by RF interference, RMI, etc., for usage in high-end audio and professional audio (studio, live sound environments).
  • Furniture-grade smooth satin black painted finish. Unlike vinyl, used by many of our competitors.
  • 7 years woofer warranty and 5 year electronics warranty.

That's one version, yes. In the consumer electronics world, it's more often used for:

Well hopefully the consumer electronics world also knows this is only ~ a $98 savings over full retail (not including possible shipping costs).

yes, unfortunately that's standard Hsu practice ... they do not deliberately inflate their regular prices just to be able to APPEAR to be offering deep discounts when on "sale" --- I've never seen anything better than a lousy 10% discount on any of their products over the years, except for the extremely rare B-stock sale.

For a 15" sub they will add about $200 for shipping, depending on how far you are from SoCal. So this $2200 becomes closer to $2400 with shipping. Before taxes. As I said before, this is a "for hard-core bassheads only" kind of product. 😊

I have the HSU TN1 and 15H-MK2. They produce great bass. As stated it's seldom HSU has sales and they do charge shipping. I do still find their prices to be comparable or less than other manufacturers within the same tier of bass.
