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.

Items shipped back in like new condition through standard shipping carriers will only incur a flat fee of $15 to return. If the items were initially shipped through free scheduled delivery via motor freight (commonly referred to as LTL), returning them will result in return shipping fees starting at $150. These items include but are not limited to, oversized items such as TVs, certain subwoofers, floorstanding speakers, furniture, and most items weighing over 75 pounds. Return fees will also apply for exchanges. We want to treat your system as if it is our own and want you to be completely satisfied with your purchase.
Please see the instructions below. We only accept returns for any product purchased directly from our website.

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.
Overview
No.31 is nothing less than a pure reference model, sculpted from the flanks of the remarkable No.32, but using a newly developed 12″ (350mm) all carbon fiber driver. Every facet of No.31 has been comprehensively upgraded and refined from its predecessor. No.31 delivers the classic Reference filter used in No.32, the same dual parametric filters, a driver that handles three times the power to deliver a truly thrilling experience.
When Only the Best Will Do (But You’ve Run Out of Room)
No.31 exists to satisfy the needs of those who crave the finest yet have space limitations. Whilst some can afford our flagship No.32 model, it is larger and deeper than some rooms can accommodate. How can you best deliver No.32’s sound quality, build quality, and thoughtful features with a more compact footprint? Enter No.31.
Perfection Repeated
No.31 matches No.32’s design stroke for stroke, yet somehow it manages to look more svelte, crouching closer to the floor—almost feline in its grace. The elegant plated handles inset into an ellipse is retained, as is the string grille that permits vast amounts of air to explode into your room without creating noise like cloth grilles can. No.31 features the curvilinear radius to the sidewalls that define both its performance and its character. But the reduction in visual and actual three-dimensional physical mass is remarkable. No.31: when the best must be delivered in a smaller space.
Arrayed for Battle
No.31 permits the same vertically stacked line array as the ultimate No.32. It delivers transformative performance that no competitor has been able to. For those who have been seeking the ultimate musical and theatre experience, Line Arrays unlock the final dimension of system reproduction. Audiophiles have chased three-dimensional sound for years, yet they have missed the simple fact that the height—not the depth—of image is the missing link. By creating products that are designed to be stacked 3 (or in exceptionally tall rooms, 5) units high while retaining individual crossover and gain control of each subwoofer in the array, REL has created a masterpiece that finally delivers what the most experienced audiophiles have been chasing for the past 40 years.
Amplified Perfection
No.32’s NextGen 7 Class D 1,000 watt amplifier also lives inside No.31, only limited to 900 watts to ensure the perfect complement to the 12” bass engine within No.31. This allows the maximum dynamics to be delivered while ensuring a long, cheerful life for both components. Here too, the LimitLess Limiter, which permits the amplifier to tiptoe right up to its limit without audible compression is part of the magic, conveys a rhythmically effortless quality. Also, its dual parametric filters allow precise micro-tuning; the deepest bass is slightly reinforced, while the upper ranges of bass can be gently trimmed to ensure a brilliantly rendered transition from bass to the main speaker. The electronic design of the reference range is itself artistry.
Drive This
The incredible excursion of the 12” pure carbon fibre driver allows it to play as loud as its larger stablemate. Yet, the No.31 possesses the tactility, nimbleness, and attack that only the greatest subwoofers have ever been able to deliver. Also, its sonic signature works in modestly-scaled rooms and with a vast range of fine speakers. The driver is accelerated by a specially wound 3” voice coil driven by a 13-pound magnetic structure; even near its limits, the voice coil remains solidly inside the gap. It is this visceral power, coupled with great delicacy and nuance, that is No.31’s signature.
Total Control
Take control of your No.31 by grasping the REL Reference Remote Control. Immediately, you will be struck by the perfect fit in your palm, the result of careful thought and numerous generations of trial-and-error fittings during prototype development. The second reaction to it is the awareness of its mass, which conveys its quality, permanence, and immutability. It tells you, “I am a thing of substance, of quality. Pay attention, what you do next matters.” If you have owned a REL in the past (and fully 90% of Rel Reference owners are), all the familiar controls are right at hand, exactly where you’d want them. High (or low if using active speakers) level gain sits comfortably to the right side, the crossover rests in the middle, and .1/LFE gain is off to the left.
Below are three lovely metal toggle switches handle the critical setup functions. The remote’s on/off switch is at the bottom. It is both as out of the way as possible and remains on once turned on and in use during setup without being accidentally turned off. In the middle sits the phase control. This is used only initially to determine the correct 0 or 180 degrees of phase. Additionally, the top access to the Dual Parametric EQ-marked with A and B—permits the flattest, deepest bass and, at the other end of the bass frequencies, the fine-tuning of crossover behavior. This gives you the perfect blending of subwoofer to main speakers and any vestiges of room-generated boom and resonance can be gently trimmed away.
REL’s Reference Remote reminds you of the perfect butler—always immaculate, indispensable when called upon, then quietly set aside until a future time when perhaps additions or further improvements to one’s system further require its services.
