VTF-15H MK2 Subwoofer
The VTF-15H MK2 is our new flagship model that features balanced inputs, integrated flare triangular ports, variable Q control, and hybrid operation (including both sealed and ported modes). Between the Q control, operating modes, and EQ choices, it caters to virtually any audiophile’s preferences and room. The new 15-inch woofer has twice the magnet of the original 15H woofer, plus a cast frame to support the much heavier motor structure. The extremely light fiberglass reinforced cone plus multiple shorting rings means extremely tight, clean and dynamic bass, especially when you set the Q control to a low Q.
The use of the new integrated flare triangular port allows us to get the biggest possible port for each subwoofer. We are no longer limited by diameter of standard size port tubes. The triangular ports tuck away nicely in the corners of the panel, allowing a compact panel size to accommodate a large woofer and large ports and yet provide a visually striking look that matches the expensive custom black paint, much higher quality finishes than most of our competitors.
In fact, this subwoofer, in our opinion, is also our best looking sub. It has a refreshing, unique and stylish look.

"Audioholics Top AV Gear Guide for 2015: High End Value Pick: HSU VTF-15H MK2"
"If you don't mind a huge box and your goal is the most possible output and extension from an affordable sub, you would be hard pressed to beat the HSU VTF-15H MK2 sub. We reviewed the first version of the sub which did very well in our testing. HSU took it up a notch this year with a more powerful amplifier and higher excursion driver. This sub is one of the most affordable subs on the planet to earn the Audioholics Extreme Bassaholics rating. The hefty 15" driver with beefy 600 watt (continuous rated) amplifier and tunable modes also makes it the most flexible. Be warned this beast weighs a whopping 110lbs so it's no small feat to move. It will surely satisfy Granpda Simpson as he yells "turn it up" during the THX intro just before his dentures shatter."
"On to the Best Real World Gear award, with 'Real World' meaning gear that's not only highly affordable but a legit performer. Without question, this award goes to the incredibly gracious folks at HSU Research." Home Theater Shack (The "Best of" AXPONA 2015) , Apr 2015
"I’m giving both subs a Top Pick for their performance, and I'm not letting the VTF-15H MK2 leave my home." Sound and Vision, Feb/Mar 2015
"The VTF-15H MK2...is highly flexible and will win you over with its (literally) explosive performance. It delivers amazing bang for the buck and stands as the only sub on our list that netted five stars across the board."Sound & Vision.com, December 2014
"I thought the VTF-15H delivered the most bang for the buck of any subwoofer on the market. Now the VTF-15H Mk2 delivers even more bang for about the same bucks." About.com, December 2014
"If this sequence [Space Shuttle launch] on your present system doesn't induce panic about a subwoofer-generated-damage clause in your homeowner's insurance, you need a better sub. Like the Hsu."
"It's hard to visualize a subwoofer priced this low that needn't apologize for the quality of its bass, its low-end extension, or its setup flexibility." Home Theater Magazine, December 2011
"My hats off to the Dr. I'm not sure how but that new woofer is a lot tighter, more controlled and just plain hits harder compared to the mk1."
"Saying the mk2 is an upgrade over the mk1 is an understatement. It's like someone put two mk1 subs in a mk2 box.
Sure the numbers show a 3 or 4 dB increase, but the tightness of the bass, the extra headroom, the tactile feeling, and the mid bass punch make the mk2 about much more than just a 3 or 4dB increase. It wasn't just a decibel increase it was an increase across the board that makes this sub a huge upgrade over the mk1."
"Today I played interstellar black hole scene between times of 2:18:00 to 2:19:00. Wow, my main floor was shaking even my volume was only -30db. The dishes in my main floor kitchen was shaking as well. Very impressive! so I think only one Hsu sub is good enough for me so far. I can sell my old sub now."— Roudan
"Bass notes are so much more effortless now, a bit quicker, slightly less bloat. Not that the Mk1's were bloated sounding, just that the Mk2 is tighter and reproduces everything so much easier."
— Ryan Dillin
"My vtfmk2 arrived today. Legairre, I must say that you were spot on. It does feel tighter, I believe it is because it has so much more output especially in the midbass that it is just ridiculous. It gives me more stress in movies because of how hard it hits. Great upgrade!"
"The new VTF-15 MK2 is absolutely incredible! It has made my system incredible! And, it is all black. Great job Dr. Hsu!"
"I got my VTF 15H MK2 this weekend and was really blown away. The amount of detail in the bass and how smooth it blended in with my speakers is great."
"I watched Interstellar last night and was just amazed by the 15H Mk2. At times, I thought the apartment might vibrate apart lol "
