Status Update: Discontinued. The VTF-15H MK2 has been replaced by the new VTF-TN1. Please click here for more information.

The VTF-15H MK2 is our flagship and highest-performing subwoofer designed for the ultimate home theater experience. With its exceptional capabilities, the VTF-15H MK2 stands as the pinnacle of performance in the HSU lineup.

  • Most popular subwoofer for home theater
  • Highest performing subwoofer that excels in output capability, especially in the deeper bass
    • Larger enclosure than the VTF-3 MK5 HP, so more efficient in the deeper bass
    • Larger ports at a lower tuning than the VTF-3 MK5 HP, so it not only plays louder and cleaner with sub 20 Hz bass (less port noise), but also plays lower 
  • Plays significantly louder and cleaner than the VTF-2 MK5 across the board (like having two of the VTF-2 MK5’s put together) without distortion.
  • Plays significantly louder and cleaner than the ULS-15 MK2 in the deeper bass (like having two ULS-15 MK2’s put together) without distortion.
  • Balanced XLR inputs to protect their signal from noise caused by RF interference, RMI, etc for common usage in high-end audio and professional audio (studio, live sound environments)
  • Offered in a smooth satin black painted finish or a real-wood veneer rosenut finish
  • For those who are worried about the size, it’s been designed to remain shorter than typical sofas so it can double as an end-table.

    How we distinguish our products from others

    What distinguishes HSU from the rest is that we are an engineering driven company. This is reflected in the quality of our products.

    It is common for other companies to focus on cosmetics and marketing gimmicks. They follow the marketing adage to "sell the sizzle, not the steak". HSU is different. We focus on pure audio engineering and on building a better mousetrap. We obsessively concentrate on product performance and reliability. Each HSU product is carefully engineered by Dr. Hsu to provide "high-end" sound in its specified room type. High-end means the best of the best. We hope you will agree.

    Attention to customers is another differentiator. Dr. Hsu, founder of HSU, consults privately with customers on a daily basis. This demonstrates his commitment to product quality and home integration. There are few companies who can make that claim.

    30-day Satisfaction Guarantee

    If you are not completely satisfied with your purchase, you have 30 days from receiving the item to begin the return process. The customer is responsible for organizing return shipping and ensuring the safe transit of the product(s). We will refund the complete purchase price, minus any shipping charges, after our technicians review the return. The refund happens under four conditions: (1) all items must be in "like new" condition, (2) there must not be any missing items, (3) the product needs to be in transit back to Hsu Research within 30 of delivery (4) you must call us to receive an RMA number. Failure to comply with these conditions may result in the item being refused, or you may be charged a 15% restocking fee. In the event that the item(s) returned arrives damaged, the customer is responsible for filing any claims with their courier. Package Orders: In the event that you receive the unit(s) damaged, a replacement unit(s) will be shipped out at no cost to you. However, if you decide to return the entire package, you will be responsible for all shipping and handling charges both ways for all returned items and the same terms as stated above will apply.

    If the shipment is rejected, or if the item is sent back to Hsu Research due to failed delivery, by no fault of Hsu Research, the customer will be responsible for shipping both ways.

    Hsu Research reserves the right to modify the 30-day tryout policy without notice.

    Fast, insured FedEx Ground Shipping

    Products are normally shipped with low cost, insured, FedEx Ground with signature required to any destination in the lower 48 states. Due to the cost of the item, we do prefer to send with signature required. However, if the customer would rather send the item with no signature required, the customer can request that in the comment section.  

    Note that for no signature required:
    1) Once the package is delivered, Hsu Research no longer assumes responsibility for the package.
    2)  Due to the value of the package, it is ultimately up to the FedEx driver's discretion whether to require a signature or not.

    We cannot modify the signature requirement after shipping. If you want to have the signature requirement removed, you would need to inform us, in the comment section, when you place the order.

    Depending on the location, many items shipped can be held at a nearby FedEx Print & Ship Center. Please contact sales@hsuresearch.com or check the FedEx website to find the nearest location to you.

    Shipping times within the 48 states are typically 1-5 business days depending on the location. Note that shipping and delivery times are estimates only and are not guaranteed. Hsu Research is not responsible if the shipment is delayed. The day your order is shipped, your FedEx tracking number will be emailed. For online orders, we also update your tracking page with the tracking information. If you do not receive it, be sure to check your spam folder, as some emails tend to end up there. If you are unable to locate the tracking number, give us a call or send us an email at sales@hsuresearch.com and we will be happy to provide you with the tracking info.

    For orders shipped outside of the contiguous United States, there will be an additional shipping and handling charge. Email sales@hsuresearch.com for a shipping quote.

    It is strongly recommended that you inspect the item as soon as it is delivered. If the item has arrived damaged, Hsu Research must be notified within 21 days of receiving the item.

    Do you offer a local pickup option?

    Yes, we offer local pickups. If you would like this option over shipping, please give our office a call. It's important to note that for local pickup, you won't be able to pay using PayPal. But all other forms of payment are acceptable.

    Industry Reviews

    "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."

    Bob Ankosko, Sound & Vision.com

    "It has excellent deep bass extension with a response that is flat to 16Hz as well as very powerful mid-bass output that can exceed 118dB in 2-meter RMS burst testing. Some subwoofers can give you a body massage, but the VTF-15H MK2 will use you as a punching bag if you let it."

    "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."

    "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."

    Brent Butterworth, About.com

    "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."

    Sound quality and power are top notch! Price is affordable compared to others.
    This thing is big and heavy so size might not be for everyone.

    Highly recommend you go with the dual subwoofer package

    I own two HSU ULS-15 MK2 which are excellent sealed subwoofers. I recently added two more HSU VTF-15H MK2 ported subwoofers to my home theater. HSU Research subwoofers are high-quality and of great value. Not only that but HSU research customer service is fantastic. I was able to reach out to them on the phone and chat. Kevin even offered me advice and tips to try out to get the most out of what I had before adding more subwoofers to my home theater. I highly recommend you go with the dual subwoofer package. It really helps with placement options, nulls, and bass distribution in your room. HSU Research subwoofers are a great choice for music and movies. The subwoofers are clean, can produce deep bass extensions, and are tight.

    Absolutely love it!

    I absolutely love my rosewood VTF-15H MK2! Had a friend pick up the VTF-3 for his setup who then recommended it to a friend who picked up the VTF-2. I'm a blind guy who loves to watch movies and listen to music. So, where I don't need the fanciest 4K TVs I do get a lot of added benefit from a really top-notch audio experience. Thanks for being a part of that.
