The new VTF-TN1 is our highest-performing subwoofer, designed for the ultimate home theater experience. With its exceptional capabilities, the VTF-TN1 stands as the pinnacle of performance in the HSU lineup.

  • Highest performing subwoofer that excels in output capability, especially in the deeper bass.
  • Classic variable tuning frequency (VTF) with dual 4” down-firing ports - hidden from the dogs, cats, and toddlers.
  • Perfect height acoustically, to use as a speaker stand.
  • Features balanced XLR, unbalanced RCA and high level inputs for greater flexibility.
    • Balanced XLR inputs protect against noise caused by RF interference, RMI, etc for usage in high-end audio and professional audio (studio, live sound environments).
  • Compared to other HSU subs:
    • 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) with low distortion.
    • Plays significantly louder and cleaner than the ULS-15 MK2 in the deeper bass (like having two ULS-15 MK2’s put together) with  low distortion.
    • Among the smallest footprint - similar to the ULS-15 MK2.
  • Replaces our previous flagship VTF-15H MK2:
    • Tuned to go even lower, with a flatter frequency response.
    • Less port noise and compression.
    • More affordable price.
    • Smaller footprint: won't fill up your living room, and more placement options for optimal sound.
    • Same internal volume.
  • Can also be laid on its side if preferred. Less deep than most sofas, makes a good end-table.
  • Furniture-grade smooth satin black painted finish. Unlike vinyl, used by many of our competitors.
  • 7 years woofer warranty and 5 year electronics warranty.

    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 UPS Ground Shipping

    Products are normally shipped with low cost, insured, UPS 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 UPS 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 UPS Store. Please contact sales@hsuresearch.com or check the UPS 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 UPS 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.

    VTF-TN1 Overview

    Industry Reviews

    "Hsu has made something that plays deeper bass at a lower price and increase the electronics warranty to 5 years of coverage... There are a few subs that can dig below 20Hz that can be had for less than the VTF-TN1...but none of them are in the same output class as the TN1...and they all cost significantly more than the VTF-TN1...[TN-1] would be my first pick." "...there isn’t anything else that can quite match its overall performance for the cost."

    VTF-TN1 NICE SUB!

    Received my vtf-tn1 couple weeks ago. It replaced a very old velodyne 10" sub. The room is 12' x 40' x 8'. The new sub is currently along the 12' wall with my philharmonic bmr towers, ht center and aam surrounds. I also have kefs for my back surrounds. The seating area is about 10' from the 12' wall. The new sub really enhances 2 channel for music. Really clear lows. It's awesome for movies in surround. If I desire, which I usually don't, I can shake the whole house with it, with ease.

    My only complaint is: there is a small gouge in the left side of the vtf-tn1 (a little smaller than the size of a pencil eraser). Not enough for me to send it back or impact performance. The outter box had a small tear, but the inner box, foam and cloth sleeve were fine, so I hesitate to think it was damaged during shipping.

    Clean, deep bass

    This subwoofer is everything Dr. Hsu claims it is. The bass is very deep. My Audyssey calibration software measures it going right down to the 14hz that the spec claims. And it does it effortlessly. You can feel it pulsating right through your body.

    But this is a big subwoofer. More specifically, I should say this is a very tall subwoofer. At 32 inches, it's nearly three feet tall. Even behind a large Marquis chair-and-a-half, it still peeks out. On the positive side, my wife put a flower arrangement on it.

    If you have the space for it, this is an extraordinary subwoofer and incredible value for the money.

    I Love it!

    Have had many subs and this outperforms them all, a huge difference to my system and saving for another one. Best value period.

    A great Sub

    This sub extends very low, and does so effortlessly.

    Positively Feeling the Lows

    The upgrade of my home theater/music system started with the subwoofer, and after some research and various demos of top subs, I found myself mysteriously drawn to the Hsu VTF-TN1. Once I had it integrated and calibrated with my system, I knew I had made the correct choice. It played as low as you please, yet smooth as silk. I wanted a sub that was as good with music as with the demands of home theater. The VTF-TN1 shined in all applications, and even enhanced the sound of my 20 year old bookshelf speakers. This versatile sub can be as musical or as explosive as you need. I was so impressed that I purchased a second, which has given me an immersive sound experience that never disappoints.
