REL Acoustics Cart-1 for Planar 1 Subwoofer - Piano Black
What You Need to Know
What Is the REL Planar Cart-1?
This is a rolling cart accessory designed specifically for the REL Acoustics Planar PL-1 subwoofer. It is not the subwoofer itself—this listing is for the cart only.
The REL Planar PL-1 is an ultra-slim subwoofer built to mount on your wall or sit close to it. But not every room is ready for wall mounting. Maybe you rent. Maybe you like to rearrange. Maybe you just want to try a few spots before you commit. That’s what the Cart-1 is for. It adds a caster wheel and a chromed foot to your PL-1, turning it into a mobile, free-standing subwoofer you can roll around the room.
Why Does It Matter?
Subwoofer placement makes a real difference in how bass sounds. Even small changes in position can change how deep, smooth, and natural the bass feels in your room. With the Cart-1, you can wheel your PL-1 from spot to spot, listen, and adjust until it sounds right—no drilling, no heavy lifting, no guesswork.
According to REL, the Planar Cart was designed as an extension of the subwoofer itself. Its proportions, spacing, and stance were carefully planned to preserve both performance and visual balance when the Planar comes off the wall.
There’s a sound-quality reason for the cart, too. The PL-1 is designed to work closely with the wall behind it—the wall actually helps reinforce the bass. The cart holds the subwoofer at the proper distance from that wall, so the bass stays stable and predictable wherever you place it.
What Early Coverage Says
One thing to know: the Planar series is brand new (it began shipping May 20, 2026), so full hands-on reviews of the Cart-1 haven’t been published yet. We’ll update this page as they arrive.
Is the Cart-1 Right for You?
You own (or are buying) a Planar PL-1 and can’t—or don’t want to—mount it on the wall.
You rent your home and need a no-drill setup that still sounds great.
You like to fine-tune your system—roll, listen, adjust, repeat.
You want to wheel the sub out of sight when you’re not listening.
You rearrange your room often, or your space does double duty.
How It Works With Your System
The Cart-1 bolts onto your Planar PL-1 and becomes its floor stand. Keep in mind, this is an accessory only—you’ll need the PL-1 subwoofer to use it. The PL-1 itself connects to your system with high-level, low-level, or LFE cables, or wirelessly using the AirShip Direct transmitter that comes with the subwoofer. The cart doesn’t change any of that—it just changes where the sub can live. If you have questions about setup, give us a call at 800-942-0220 and we’ll help.
What’s in the Box
- REL Planar Cart-1 (one unit)
- (Verify complete box contents with REL Acoustics. For reference, the companion Cart-2 ships with a base, handle, three mounting bolts, an Allen wrench, and a detachable foot—the Cart-1 likely includes similar hardware.)

Features & Specifications
Purpose-Built for the PL-1 — This cart is designed and made by REL Acoustics specifically for the Planar PL-1 subwoofer. Its proportions and stance were planned around the PL-1’s size and weight.
Roll It Anywhere — A caster wheel (a small swiveling wheel) and chromed foot let you move the PL-1 easily, then keep it planted once it’s in place.
Keeps the Bass Right — The cart maintains the proper spacing between the PL-1 and the wall behind it, so the subwoofer’s wall-coupled bass design keeps working as intended.
Two Finish Options — Available in Gloss White and Piano Black to match your PL-1 cabinet finish.
No Wall Required — Get full Planar flexibility without drilling—great for renters and rooms that change.

Frequently Asked Questions
Does this include the subwoofer?
No. This listing is for the Cart-1 only. The REL Planar PL-1 subwoofer is sold separately.
Will the Cart-1 fit the Planar PL-2?
No. The Cart-1 is built for the PL-1’s exact size and weight. The larger PL-2 uses its own cart, the Cart-2, which we carry separately. Make sure you order the cart that matches your subwoofer.
Why not just set the PL-1 on the floor?
The PL-1 is designed to work with the wall behind it—the wall helps reinforce the bass. The cart holds the sub at the correct distance from the wall and keeps it stable, so you get the performance REL intended without mounting anything. It also makes the sub easy to move.
Do I need tools to put it together?
Some simple assembly is involved. The companion Cart-2 ships with its mounting bolts and an Allen wrench included, and the Cart-1 likely follows the same approach. Check with REL for the latest details, or give us a call and we’ll help you figure it out.
Can I still use the PL-1’s wireless connection on the cart?
Yes. The PL-1 has wireless built in and includes REL’s AirShip Direct transmitter. On the cart, that means the only cable you need is the power cord—which makes rolling the sub around even easier.
Which finish should I pick?
Choose the finish that matches your PL-1: Gloss White for the Gloss White Lacquer subwoofer, or Piano Black for the Piano Black Lacquer version. That way the cart looks like a natural extension of the sub.
Will moving the subwoofer around change the sound?
Yes—and that’s the point. Bass behaves differently in different parts of a room. The cart makes it easy to try a few spots and find where the bass sounds deepest and most even. Roll, listen, and adjust until it feels right.
