It is \u003cstrong\u003enot\u003c\/strong\u003e the subwoofer itself—this listing is for the cart only.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Does It Matter?\u003c\/h3\u003e\n\u003cp\u003eSubwoofer 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.\u003c\/p\u003e\n\u003cp\u003eAccording 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.\u003c\/p\u003e\n\u003cp\u003eThere’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.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Early Coverage Says\u003c\/h3\u003e\n\u003cdiv class=\"ec-blockquote\"\u003eLewis Empson at What Hi-Fi? (May 2026) noted that the rolling cart option lets you move the Planar subwoofer easily and store it out of the way when you’re not listening.\u003c\/div\u003e\n\u003cdiv class=\"ec-blockquote\"\u003eReviewers at eCoustics (May 2026) pointed out that the cart setup solves two problems at once for floor placement: keeping the right spacing from the wall and keeping the subwoofer stable.\u003c\/div\u003e\n\u003cp\u003eOne 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.

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.

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.\u003c\/p\u003e\n\u003ch3\u003eWhy not just set the PL-1 on the floor?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eDo I need tools to put it together?\u003c\/h3\u003e\n\u003cp\u003eSome 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.\u003c\/p\u003e\n\u003ch3\u003eCan I still use the PL-1’s wireless connection on the cart?\u003c\/h3\u003e\n\u003cp\u003eYes. 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.\u003c\/p\u003e\n\u003ch3\u003eWhich finish should I pick?\u003c\/h3\u003e\n\u003cp\u003eChoose 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.\u003c\/p\u003e\n\u003ch3\u003eWill moving the subwoofer around change the sound?\u003c\/h3\u003e\n\u003cp\u003eYes—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.
