Rerouting and Address Changes
We cannot make ANY address changes once an order is placed. If you are unable to accept delivery of your package as ordered, we will need to cancel your order, return the package to sender and have you replace your order through our website.
Keep the Box
We suggest you keep the shipping box or boxes for at least 30 days. It is actually a great idea to keep boxes for audio products for the life of the product. Having the box and all packing will increase the trade-in value should you decide to move up and they are handy to have should you ever need to send the unit in for repair.
How To Receive a Motor Freight Order
The trucking company will contact you to schedule a convenient time to deliver the order. Please note that you must be present for delivery.
Visually inspect the box to make sure you see no signs of damage. If you notice any damage at all, take some pictures with your phone and make a note of them on the delivery receipt the driver will ask you to sign. If it is obvious that the product is damaged, please refuse the order and contact us immediately at 888.899.8776 or email support@audioadvice.com.
Open your box as soon as possible and inspect the product for damage and contact us if you find anything wrong.
uShip In-Home Delivery
Due to current concerns surrounding COVID-19, uShip is able to offer THRESHOLD SERVICE ONLY at this time. To ensure everyone’s safety, uShip is advising carriers to refrain from making room-of-choice deliveries. Threshold service consists of the shipment being brought into the first door of the address or the lobby of an apartment/condo, and does not include set-up, installation, assembly or debris removal.
What to Expect: Most oversized items will be delivered within 2-3 weeks. Your carrier will place your item inside the first door of the address or the lobby of an apartment/condo.
Appointment Scheduling: Your delivery partner will call 24-48 hours prior to delivery to arrange an appointment window.
How to prepare for in-home delivery:
- Determine the clearest path from the street to your home
- Measure entrances and hallways to ensure your item will fit
- Remove any wall hangings or clutter to ensure a clear path and to prevent damages
- Remove old furnishings to allow placement for your new piece
Check your furniture for damages: We rarely expect damaged furniture, but in the instance it does happen, we have you covered. Once your item’s packaging is removed, check for any damages that may have occurred in transit. Take pictures of any damages and notate appropriately on the delivery receipt. Keep possession of the damaged piece and contact us via phone or email and we’ll start the process to repair/replace your new piece of furniture. For uShip customer support, please call 800-698-7447.

Is It Easy To Return An Item?
Yes, simply give us a call at 888.899.8776 or you can email our support team at support@audioadvice.com. Many times our team of experts can help figure out why the product might not be working like you expected and get things fixed over the phone, so don’t be surprised if we ask a few questions, we love troubleshooting!
If our tech help can not make you happy, we will email over a return shipping label with a Return Number.
Hopefully, you saved all of the original item’s box and packaging inserts. You will want to pack back up your return or exchange in the same way it came out of the original box. Once you have everything packaged correctly, tape the box on the top and bottom to assure it stays together. If Audio Advice shipped the item to you inside a second box, it's a good idea to use that same extra box to help prevent damage on its way back to us. To avoid it accidentally coming back to you, use a magic marker to cross out the old shipping label or just tear it off.
The return shipping label we send you will have our address on it, just make sure you take the box to the right shipper (UPS, FEDEX, or USPS) as per the label.
If you are close to one of our stores, please let us know if it is more convenient for you to return it to us directly. You will still need to get a return number by contacting us and shipping and/or restocking charges may apply.
When Will I See My Refund?
It usually takes around 7-14 days for the refund to show up on the payment method you used. We do inspect all returns for damage and accuracy of the item inside the box before issuing a refund. Some items may be subject to shipping and restocking fees.
Can I Exchange My Purchase For Something Different?
Sometimes those big speakers just don’t fit in the room or you might have bought a small subwoofer and later found out you’d love a bigger one. If you would like to make an exchange within 30 days of receiving your item, just give us a call at 888.899.8776 or email support@audioadvice.com and we will help work out the details. Additional shipping charges and return costs may apply.
How Do I Cancel An Order?
If the item has already shipped out or is a special order item, it is not possible to cancel the order. Please contact us at 888.899.8776 or email support@audioadvice.com to start the return process.
What If I Find Shipping Damage?
We need to know right away about any shipping damage. Please contact us at 888.899.8776 or email support@audioadvice.com within 48 hours of your delivery so we can get the ball rolling on making things right. It’s very helpful to take some pictures and email them to us if possible.
Can I Refuse A Shipment?
You can, but unless the item is damaged, shipping and restocking fees will be deducted from your refund. If your item arrives damaged and you are lucky enough to be there, snap some quick pics and refuse the order. Then contact us so we can get a replacement on the way.
What Happens If My Order Is Defective?
This is actually pretty rare, most consumer electronics work fine out of the box 99.9% of the time. We’d like for you to contact us first by calling 888.899.8776 or email support@audioadvice.com so we can help get to the bottom of things. If your item is indeed defective during the first 30 days, we can usually exchange it for a new, replacement unit.
What About Service After 30 Days?
Audio Advice has a great relationship with all of our brands and can help you with warranty service by the brand after our 30-day guarantee period. Even after the warranty expires, we can arrange for service by the brand on products purchased from Audio Advice. Just call 888.899.8776 or email support@audioadvice.com.
How Do You Determine A Restocking Fee?
You may not believe it, but sometimes we receive items back that were put in the box with zero packaging and are completely destroyed or are missing many of the pieces that came with the item. We also track serial numbers and will get back different serial numbers. We’ve even seen different items than what we shipped out be returned. However, it’s very important to package your return properly so that nothing goes missing or gets damaged in shipping, which will result in a restocking fee or even no refund at all. If a product is opened and the market value of the product is reduced, then a restocking fee may be applied to the cost of restocking and the reduced market value of the product. The bottom line is if you treat us fairly, we will do the same.
Audio Advice strives to provide industry-leading support and service while also maintaining the lowest prices available on products for our customers. We work hard with our vendors to bring our customers the best products at each price point. As a part of that process, we work with our vendors to provide the lowest pricing in our stores and on our website.
Our prices should always be the same as any other authorized dealer, including big-box retailers and major online retailers.
If you believe that you have found a lower advertised price from a legitimate authorized seller, call us and let us know so we can make sure we can correct any inadvertent error on our side. As a matter of policy, we update our prices automatically if a vendor changes its authorized pricing policies, so we generally have the best prices all the time. Increasingly, there are knock-off copies of products online, usually sold by non-authorized dealers.
Please be sure that the item meets the following conditions:
- The item is brand new, in stock, and available for purchase
- The item has the identical model number, color, etc as the item on our site.
- The seller is an authorized dealer
As always, our goal is to provide a terrific customer experience, including industry low prices. We appreciate your support.

Music Integrity Engine® (MIE) – KEF’s Proprietary DSP Algorithm
When it comes to speakers, accuracy is everything. Thanks to KEF’s proprietary Music Integrity Engine, Kube delivers more depth, greater output, and increased dynamics than ever. KEF’s Music Integrity Engine is a proprietary suite of in-house written DSP (Digital Signal Processing) algorithms, serving as the mastermind behind the detailed and accurate sound that characterises their wireless speakers and subwoofers. Tailored for each model, this ensures that every component works in perfect harmony to an even higher level than would otherwise be possible. Having learned from the development of LS60 Wireless and KC62, for Kube we’ve been able to further improve accuracy, especially at high output levels.
iBX Intelligent Bass Extension
Part of the Music Integrity Engine, iBX Intelligent Bass Extension creates an extended depth that unlocks the full potential of the custom driver. By analysing your input signal and making multitudes of tiny adjustments every second, iBX allows the subwoofer to play louder and remain dynamic at any listening level. In step with the advancements developed by MIE, the new version of iBX lowers distortion still further. The end result is simply remarkable accuracy.
Feel The Force
Kube boasts a front-firing long throw driver, producing higher output at lower frequencies. This approach creates a sensation of direct force into the room, creating a tactile, pressured, and powerful bass experience. With high SPL and low-frequency extension, Kube faithfully reproduces the lowest octaves in both movies and music, ensuring an immersive, impactful sonic environment.
300W Class D RMS Amplifier
Optimally designed for the driver and the available acoustic volume, the Class D RMS amplifier in the Kube runs efficiently and cool, providing ample power for the subwoofer. It reproduces deep bass and rumble with precision and dynamic, adding intensity and realism to your audio experience.
Versatile Connectivity
With a comprehensive range of connection options, Kube adapts easily to a wide variety of audio systems. Featuring line level/speaker level inputs, it can be connected to any amplifier. KEF SmartConnect automatically determines whether a mono or stereo input is being used, optimizing the gain for optimum performance. Additionally, Kube is compatible with the KW1 wireless subwoofer adapter for simple wireless integration.
3 Pre-Sets For Easy Integration
Thanks to Music Integrity Engine, Kube features a placement-dependent EQ section that can be easily adjusted to maximize in-room performance. With three room placement setting options, Kube easily fits into any environment, ensuring consistent performance wherever it is placed, whether snugly fitted in a cabinet, against a wall, or in a corner.
Power Tailored To You
Kube benefits from a flexible choice of power-on modes tailored to your system's requirements – music sense for standby wake-up upon audio signal detection, 'always on' for instant readiness, and 12V trigger for a single button switch on in an integrated home system.
Seamless Elegance and Thoughtful Design
As well as working with the room acoustically, Kube's sealed cabinet is designed for easy positioning. Coupled with the minimal, contemporary design, Kube subwoofers blend seamlessly with any interior. The Kube is available in four sizes: 15", 12", 10", and 8" driver, offering a solution to suit any room and application, such as music, home theater, and gaming.
