Introducing the VTF-15H MK2, the new flagship subwoofer from HSU Research that is designed to cater to the most discerning audiophiles. This subwoofer boasts a host of features that ensure it delivers unparalleled performance and versatility. The VTF-15H MK2 includes balanced inputs, integrated flare triangular ports, variable Q control, and hybrid operation, including both sealed and ported modes. With these features, you can easily adjust the subwoofer to your room and preferences for optimal performance.

One of the standout features of the VTF-15H MK2 is the new 15-inch woofer that has twice the magnet of the original 15H woofer and a cast frame to support the much heavier motor structure. This woofer also features an extremely light fiberglass reinforced cone plus multiple shorting rings, which results in tight, clean, and dynamic bass. You can further optimize the bass response by setting the Q control to a low Q.

The VTF-15H MK2 also boasts an innovative design that includes integrated flare triangular ports, which allows for the biggest possible ports for each subwoofer. These ports tuck away nicely in the corners of the panel, providing a compact panel size that accommodates a large woofer and large ports while maintaining a visually striking look that matches the subwoofer's expensive custom black paint.

The VTF-15H MK2 represents the pinnacle of subwoofer performance and versatility from Hsu Research, and is the perfect choice for anyone looking for a high-performance subwoofer that can handle even the most demanding music and home theater applications.

    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."

    "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’m giving both subs a Top Pick for their performance, and I'm not letting the VTF-15H MK2 leave my home."

    "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."
