RoadPro RPSP-15 Universal CB Extension Speaker with Swivel Bracket (2-3/4 x 4-1/2 in)
Product description
If your CB radio setup feels a bit “trapped” behind dash clutter, a dedicated extension speaker can make a noticeable difference. The RoadPro RPSP-15 is built for that exact situation: add a speaker you can place where you’ll actually hear it. On paper, it’s a simple, purpose-driven add-on—durable enough for vehicle use, and flexible thanks to a swivel bracket.
What it is and what it’s for
The RoadPro RPSP-15 is a universal CB extension speaker designed for use with CB radios only (not a general-purpose audio speaker). It comes with a durable metal mesh grill, a swivel bracket for positioning, a 3.5mm plug, and an 8' cord. The goal is straightforward: clearer, more convenient audio access from your CB radio without relying solely on the radio’s built-in sound.
A practical way to think about it: if you do a lot of highway driving or have work that keeps you moving around the cab, mounting the speaker higher or aimed toward your seat can reduce how much you have to “hunt” for audio. You set it once, then you can focus on the road or the task.
What you’ll notice day to day
This speaker’s strongest selling points are the kind that matter in real installs—placement and durability.
- The swivel bracket helps you aim the speaker where it counts, rather than settling for whatever direction the radio’s sound happens to come from.
- The metal mesh grill gives you a more vehicle-friendly exterior look and feel than delicate speaker grilles.
- The included 3.5mm plug and an 8' cord simplify routing compared to setups where you have to improvise cabling.
That said, it’s not perfect for every scenario. Since it’s for CB radios only, it won’t fit the role of a versatile speaker for other audio devices. And because we don’t have installation hardware details beyond the swivel bracket, you may still need to think through how you want it secured in your specific space.

Who it suits best—and where it may fall short
It’s a solid pick if your priority is getting CB audio you can hear easily while keeping your radio setup tidy. If you like the idea of aiming the speaker toward your seating position (instead of listening to “wherever it happens”), the swivel bracket is the kind of feature you’ll appreciate quickly.
It may not be the best choice if you need a plug-and-play speaker for non-CB use, or if your install plan doesn’t benefit from an 8' cord length and a fixed mounting location. Also, if you’re expecting high-end sound tuning or studio-like clarity, remember this is positioned as a CB utility speaker—not an all-around audio upgrade.
How to evaluate compatibility before you buy
Before ordering, double-check that your CB radio setup matches the intended connection and use case. The RoadPro RPSP-15 is specified for CB radios only and uses a 3.5mm plug, so your main homework is whether your radio’s audio output supports that type of connection.
Also, think about placement. Since this includes a swivel bracket, you’ll get the most out of it when you can position it toward where you’ll be listening most of the time.
Quick setup tips (so it doesn’t become a hassle)
Start with rough placement before finalizing anything. In a typical cab install, you’d place the speaker near where your voice/traffic chatter will be audible—often higher than you think, aimed slightly toward the driver’s seat. Then route the 8' cord so it avoids pinch points and doesn’t interfere with controls or seat movement.
Once you’ve got it roughly where you want it, use the swivel bracket to fine-tune direction. That one step can make the difference between “installed” and “actually helpful.”
Should you buy it?
Buy the RoadPro RPSP-15 if you want an uncomplicated CB-specific extension speaker with a durable metal mesh grill, a swivel bracket for better audio direction, and a straightforward 3.5mm connection with an 8' cord. It makes sense for drivers who rely on CB communication and want the sound closer to where they’re listening.
Skip it if you need a speaker for non-CB audio, you’re not confident your CB radio supports the 3.5mm plug arrangement, or your space doesn’t give you room to place and aim it effectively. In short: it’s a practical CB add-on, not a universal audio solution.
