Introducing the VTF-2 MK5, the epitome of affordability and value in the renowned HSU lineup. This subwoofer is designed to cater to budget-conscious enthusiasts without compromising on quality or performance.

  • Most affordable and budget-friendly subwoofer 
  • One of the smallest subwoofers so it works well in tighter spaces, yet doesn’t compromise on quality
  • Better performance below 20 Hz frequency than the ULS-15 MK2
  • Plays lower in extension over the ULS-15 MK2
  • Variable tuning provides more flexibility and allows customers to choose lower bass or higher output capabilities - it’s like having three subwoofers in one!

    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

    "For home theater enthusiasts and audiophiles, the Hsu Research VTF-2 MK5 12-inch subwoofer is the stuff of dreams."

    "The HSU VTF-2 Mk5 subwoofer is truly a "True Subwoofer".  I get in-room response down to 25Hz before it starts to roll off.  But, it not only goes deep.  It is the antithesis of a one-note bass.  The bass is tuneful and I am thrilled with it in my otherwise all-Magneplanar surround sound system.  The price is extremely good for the quality of the speaker and provides extreme value."

    "I bought your VTF 2.4 and I have to say, not only am I impressed but every single person who has heard it so far has been in awe. "


    " if I were shopping for a subwoofer at its price point, it would very likely be my first choice."

    Great Sub and Great Value

    This one is my third Hsu subwoofer, the others being VTF-3 MK5s. It has all the same features, sounds the same, and costs less. It goes as low as the bigger subs. It just doesn't play as loud, which doesn't matter much since they all play past deafening. It's a great value and Steve Guttenberg thinks so too.

    Great sub

    So far love it. Can't beat it, especially for the price.


    Amazing sub!

    2nd Sub

    Just recently finished my theater. Already had one vtf2 mk5 and the room was lacking bass in areas. I added a second and now I have even bass front to back. HSU is the only brand of sub I have ever owned. Started of with a stf2 which worked where I was but when I finished the theater I knew I needed more. Now that I have 2 vtf2 mk5, I hate to say it but I can’t see me wanting more as they all I need and more.
    Thanks HSU


    Product is good, but the FedEx delivery guy didn't ring my door bell. This is the wrong time of the year to NOT RING MY A CUSTOMERS Door bell.
