The new VTF-3 MK5 HP sets a new standard for high-end performance at an affordable price point. It’s earned its reputation as one of the best value ported 15" subwoofers on the market.

  • Customer favorite and best seller 
  • Smaller enclosure than the VTF-15H MK2 (4” less depth) and lighter, but nearly identical in performance for the majority of audio material
  • Plays significantly louder and cleaner in the deeper bass over the ULS-15 MK2 for just a small increase in price.
  • Output is equivalent to two VTF-2 MK5’s across the board at frequencies above 25 Hz 
  • Most inexpensive ported 15” subwoofer in our offerings (of 2)
  • Identical performance to the VTF-15H MK2 from 25 Hz on up
  • Considered one of the best value ported 15” subwoofers
  • 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.
  • Offered in a smooth satin black painted finish

    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.

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.

You get low-distortion deep bass that nearly rivals the performance qualities of just about any great subwoofer on the market.

This sub can shake your room as well as any other 15" sub out there and it sounds really good in doing that. And don't forget that the VTF-3 MK5 HP is a very flexible unit - you can dial in the response for just about any system and it can be re-adjusted if you move rooms or add new components to the mix.The Hsu VTF-3 MK5 HP sub is recommended for any home cinema enthusiast who has a real-world budget and even those who could spend more but don't need to because the Hsu gives them everything they want."

    Jim Clements, Secrets of Home Theater and High Fidelity

    "Ever since its launch over five years ago, the Hsu Research VTF-3 mk5 remains one of the most consistently recommended subwoofers by audio enthusiasts and not without good reason. It offers both tremendous output as well as solid low-frequency extension down to 20Hz. But it is not just quantity of bass that is produced but very high-quality bass, so the sound is clean and linear with low-distortion as well as sharp with low group delay."

    "Put succinctly, this subwoofer is amazing. It wants for absolutely nothing and can hold its own with any product being sold for under a grand. When you consider all the tuning options, and realize the flexibility that affords, you quickly come to the conclusion it has few legitimate rivals. The HSU VTF-3 MK5 HP should be on your short list if both quality and quantity is what you're after."

    Jim Wilson, Home Theater Shack

    "The performance of the Mk5 HP on subtle bass was at least as impressive as the performance during bigger bass moments.It would reproduce these incredibly loud, sometimes tortured-sounding bass events without the slightest hint that it was working hard....not going to leave my theatre room....someone with a relatively modest budget can possess a subwoofer so good that it's literally reference quality."

    Doug Blackburn, Widescreen Review, 2015

    "I was hearing dynamic shadings in my low-frequency test recordings which I had never noticed before. The VTF-3 tracked bass instruments with a clear robust tone and uncanny accuracy. "

    "The VTF-3 MK5 HP shows a quite formidable capacity to really deliver the band where the real power and force in music live. It does so with great transparency and no overhang or overtones I could detect. Micro and Macro Dynamics were outstanding. How a bass string was plucked or bowed was conveyed in great detail and the “slam factor” was considerable. The way this subwoofer was able to enhance a specific sense of the volume in a specific venue increased the soundstage’s size considerably in all directions. This bestowed greater drama to cavernous concert venues but served intimate ones quite nicely as well."

    "On track after track, the contribution of the VTF-3 only elevated the scale and force of each piece of music in an organic and holistic manner. Grooves became more entraining and percussion gained a scary realism with precise image localization. Decays were as fast or slow as the real thing, the original, and the music’s sustain in particular had a power and correctness I’ve not heard before. Transients could be felt sharply throughout my body occasionally startling both me and my cats."

    “Considering the cost relative to its competitors, the VTF-3 MK5 HP is pretty much a no brainer of a buy if one gives the slightest consideration of its truly endearing audiophile quality. I can only say in conclusion that I don’t think I could do without this sub, so I bought it!”

    Great Subwoofer

    My son loves this Subwoofer-he says it works great so far and really enhances the sounds he listens to.

    Fantastic Subs!!

    I had 15" subs that were built into my old Definitive Tech BP-2000 tower speakers. They were 28 years old and dying so I replaced them with Arendal 1723 Monitors and 2 VTF-3 MK HP subs. I picked the HSU subs because I had met Dr. Hsu some 20+ years ago at an audio show in NYC and I still remember the demo. Incredible difference with the Hsu subs! Should have made the switch much sooner.

    Excellent Experience

    I purchased the VFT-3 MK5 and it exceeds my expectations. I love it! To top it off customer service is top notch. I had some delivery availability issues with the carrier and Hsu worked very diligently to resolve the issue. I plan to buy a matching sub in the near future.

    3 years later and it's still making me smile

    I've had my VTF3-MK5 for 3 years now, and I still feel great about my purchase. Every time a new action movie comes out I'm thoroughly excited to see what in my house needs to be blue tacked down. Compared to the KEF and Klipsch subs my friends own the depths and levels this thing can dig to just blow those away. Even for music it can really keep up, especially with both ports sealed. The only reason I'm on the site today is I was hoping to get a second one. Guess I'm gonna just wait for the restock, but I know it's going to be worth the wait.

    So good it made me cry

    5 minutes in listening to this incredible subwoofer and I was both laughing hysterically and crying. I've always heard that music is an emotional experience, and while I didn't disagree with that notion, I also never really knew the reason behind that expression. I've had many subs over the years, from Klipsch, Polk Audio, and Definitive Technology. I've heard JL and SVS in showrooms, but I'm telling you: nothing compares to this, especially not at the price point. This is literally a no brainer for music and movie junkies alike. The amount of subsonic bass this unit will put out is breathtaking! It's musicality is on point, just like its accuracy. I have no reserve in recommending the VTF-3 MK5. Thank you Dr. Hsu for your incredible work!!!
