PBK 15BT: The Professional
Bi-Amplified Powered Speaker
for Any Event Where Low-End Matters

The PBK 15BT powered speaker handles applications where low-end matters. Its 15-inch woofer provides extended bass response and the volume to fill bigger rooms, backed by Bluetooth streaming, XLR and TRS connectivity, and bi-amplified power. Fanless cooling and rugged construction keep it running reliably across DJ gigs, live performances, and events where being heard is a priority.

Connect Anything, Control Everything

Bluetooth streaming for wireless audio, XLR inputs for mics, TRS jacks for instruments. Three channels with master control let you mix on the fly. 

No Fans. No Noise. No Worries.


Passive heat-sink cooling keeps the PBK running cool and quiet without fans that can fail or add unwanted noise.  

Deep Bass, Clear Output 

Bi-amplified design delivers 800 watts across the 15-inch woofer and compression driver. The result? Extended low-end response with the clarity to keep vocals and instruments defined at any volume. 

Smart Processing for Better Sound

56-bit DSP processing shapes your audio with precision, while three factory preset EQ settings let you dial in the right sound for any application from live performance to recorded playback. 

Built for Flexibility, Designed to Last

Mount it on a pole for audience coverage or set it at an angle as a floor monitor. Featuring a rugged plastic enclosure and a protective steel grille, the PBK is built to last.

Frequently asked questions

What is the power output of the Peavey PBK 15BT?

The PBK 15BT features a bi-amplified design that delivers a total of 800 watts (peak); 750 watts (peak) to the woofer and 50 watts (peak) to the high-frequency driver.

What are the key specs of the PBK 15BT?

The PBK 15BT is a 15-inch powered loudspeaker with a bi-amplified design that delivers a total of 800 watts (peak). It offers three input channels for microphones and line-level sound sources, plus Bluetooth for audio streaming and speaker pairing. The onboard DSP manages functions like the overload protection and frequency crossover, and also powers user-controlled features like EQ and signal mixing.

What inputs and outputs does the PBK 15BT have?

The PBK 15BT has three analog input channels: two with XLR and TRS connections, and one with 1/8-inch stereo and RCA stereo inputs. A dedicated channel for Bluetooth enables audio streaming. The PBK 15BT also has an XLR Mix output to chain to another speaker or a subwoofer.

Does the PBK 15BT have Bluetooth?

Yes; the PBK 15BT's Bluetooth capability allows you to stream audio or pair to a second speaker.

Can the PBK 15BT be used as a floor monitor?

Yes. The angled cabinet design directs sound towards performers, allowing you to use the PBK 15BT as a floor monitor.

How does the PBK 15BT compare to the PBK 12BT?

The 15-inch speaker gives the PBK 15BT extended low frequency response and more powerful bass, while the PBK 12BT's 12-inch speaker emphasizes stronger, more detailed midrange. Both sizes benefit from an external subwoofer for full, balanced frequency response in large spaces.

Can a 12-inch or 15-inch powered speaker fill a larger room with strong bass?

Not the kind of bass that you can feel resonating in your chest, which is why dedicated subwoofers are an integral component of sound reinforcement systems. 12-inch and 15-inch powered speakers can sound punchy and full in isolation, but in a large space with lots of bodies absorbing sound they can sound surprisingly weak in terms of bass.

Is the PBK 15BT suitable for DJ gigs?

Yes. The PBK 15BT has the input options DJs need, the link output makes it easy to scale the system with more speakers and subs, and it can be pole-mounted for elevated performance.

What should I look for in a powered PA speaker under $300 for live events?

Most importantly it should have the inputs you'll need, including line-level inputs for mixing boards and XLR mic inputs for use as a standalone vocal amplifier. To make it easy to stream music wirelessly for set breaks and background music, look for a powered PA speaker with built-in Bluetooth. If you'd like a speaker that can serve double-duty as a floor monitor, look for a powered loudspeaker that has an angled cabinet designed specifically for use as a stage monitor.

Can the PBK 15BT work as a main speaker for a small band?

It is possible, although you would also want a subwoofer for full, balanced bass in large spaces. For rehearsal applications, the PBK 15BT would serve well as a vocal amplifier so a singer can be heard over drums and amplifiers.

What is the difference between a powered and a passive speaker?

A powered speaker has a built-in amplifier to power the drivers (woofer and tweeter). A passive speaker requires an external amplifier to power the drivers. Powered loudspeakers are convenient for mobile sound reinforcement systems because you don't need to transport separate amplifiers, and they sound good because the amps are specifically matched to that speaker design. Passive speakers give sound engineers greater control over their sound system and are a smart choice for permanent installations and large-scale sound systems.

Why does fanless cooling matter in a powered speaker?

Cooling fans can create noise that may be audible during quiet passages or throughout delicate acoustic performances. A cooling fan is also a mechanical component that can potentially fail over time. Fanless cooling with a heat sink can effectively prevent overheating without inducing mechanical noise, and with no mechanical components that could potentially fail during a performance.

What does frequency response tell you about a speaker?

Frequency response tells us the range of audible frequencies a speaker can reproduce, from bass to treble. For example, a frequency response of 60Hz-15kHz would reproduce bass frequencies from 60Hz all the way through treble frequencies up to 15kHz. Below 60Hz and above 15kHz, the loudspeaker's ability to reproduce frequencies drops off drastically
