Blue Sky Sub 15 - Single – No Longer Available

15" woofer
MFR# Sub 15

Product Description

The THX pm3™ approved Blue Sky SUB 15, is a sealed box subwoofer, designed around a 15” forward-firing driver with a massive cast aluminum frame, dual 2.5” voice coils – which has almost 2.36” of excursion (peak to peak) and features an enormous 20+ Lbs. motor structure – total driver weight 36 Lbs. One of the SUB 15 Universal’s unique features is a switchable low frequency response characteristic, of either 30Hz to 200Hz +/-3dB or, in “extended LF mode”, 20Hz to 200Hz +/-3dB (anechoic). The extended mode is ideal for large rooms that don’t exhibit the room gain phenomenon of smaller sealed spaces. In addition, the SUB 15 also has built-in 2.1 bass management electronics with both a 4th order 80Hz Linkwitz-Riley low-pass filter and a 2nd order 80Hz high-pass filter that is compatible with the SAT 12’s bass-managed input and is also compatible with the I/ON, SAT 6.5 and SAT 5.

The SUB 15 is also the second subwoofer from Blue Sky which allows you to add true low frequency extension to your existing near-field and mid-field monitors. To accomplish this, the SUB 15 includes dual-independently tunable, state variable, high pass and low pass filters (50hz to 160Hz) with 4th order slopes.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
