Cobra 29 LX AM/FM CB Radio + DRX-9010 Premium Speaker + DRX-6560 Noise-Cancelling Microphone Combo

An audio-upgrade combo for drivers who already have an antenna and want cleaner transmit and better in-cab receive audio. This combo pairs the Cobra 29 LX AM/FM CB radio with two Driver Extreme audio upgrades: the DRX-9010 premium external speaker and the DRX-6560 4-pin noise-cancelling dynamic microphone. The 29 LX's stock mic and internal speaker are serviceable, but this combo is where the radio starts to sound like a professional install.

What's in the combo

• Cobra 29 LX AM/FM CB radio — 40-channel dual-mode AM/FM, 4-color LCD dot-matrix display, 10-channel NOAA weather receiver with alert tone, instant channel 9/19, Radio Check self-test, built-in SWR meter, PA capability
• DRX-9010 Driver Extreme premium external speaker — 15W nominal, 6Ω impedance, 150 Hz – 6 kHz linear response, wedge design with heavy-duty mounting bracket, detachable 10-foot 20-gauge twisted-pair speaker cable, 3.5mm right-angle plug, operating range −4°F to +140°F
• DRX-6560 Driver Extreme 4-pin noise-cancelling dynamic microphone — dynamic element with internal breath-pop diffuser, −54 dB sensitivity, 500Ω impedance, 55 Hz – 7 kHz response with proximity-effect compensation, 9-foot cord, chrome-plated grill, ergonomic contoured switch, standard 4-pin 6-conductor Cobra pinout — plug-and-play swap for the 29 LX stock mic
• Cobra 29 LX accessories: DC power cord, under-dash mounting bracket, mic clip, owner's manual (stock mic included but this combo assumes you'll use the DRX-6560 as your primary)

Why buy the combo

You save roughly 5% versus buying the Cobra 29 LX, the DRX-9010 speaker, and the DRX-6560 microphone separately. These two upgrades address the two biggest sound complaints on any stock CB install: (1) the internal 3-watt speaker is small and sits behind the radio chassis where it's easy to miss, and (2) the stock 4-pin dynamic mic isn't noise-cancelling, so cab noise gets transmitted right along with your voice. The DRX-9010 and DRX-6560 fix both problems. Don't forget to add the Pro tune and alignment option at checkout so that your radio is professionally bench-tuned for best performance per the manufacturer's service manual.

Who this combo is for

• Truckers running the 29 LX daily — noise-cancelling mic + wedge speaker is the standard audio upgrade path for anyone running CB professionally
• Drivers in noisy cabs (older trucks, high road noise, HVAC blower) where the stock mic picks up too much background
• Buyers who want the 29 LX to sound like the 29 LX-BT without the Bluetooth premium — this combo covers the two audio upgrades without the cost of the BT model
• Anyone whose stock mic has failed — the DRX-6560 is a direct plug-and-play replacement for the Cobra 4-pin stock mic

Install notes

• The DRX-6560 uses the standard Cobra 4-pin pinout (Pin 1 ground / Pin 2 audio / Pin 3 TX / Pin 4 RX). It plugs directly into the Cobra 29 LX's front-panel 4-pin microphone jack with no adapter.
• The DRX-9010's 3.5mm right-angle plug goes into the Cobra 29 LX's rear external-speaker jack. Sound automatically routes from the internal speaker to the DRX-9010 when the plug is connected.
• The DRX-6560 is a dynamic mic — no power required, no battery, no phantom power. It draws its audio signal from the Cobra 29 LX's mic gain stage.
• For maximum-performance install and bench work, add the Pro tune and alignment service at checkout so the Dynamike gain is set correctly for the noise-cancelling element.

Compatibility

• DRX-6560 works with any radio using the standard Cobra 4-pin pinout — the Cobra 29 family (29 LX, 29 LTD Classic, 29 LTD Chrome, 25 LTD Classic), General Lee, Galaxy, RCI, and many others
• DRX-9010 works with any radio with a 3.5mm rear external-speaker jack (universal on modern CB radios)
• The 29 LX's internal speaker automatically mutes when the DRX-9010 is plugged in

Cobra 29 LX Audio Combo — Frequently Asked Questions

What's included in this combo?

Cobra 29 LX AM/FM CB radio (with its factory microphone, DC power cord, mounting bracket, and mic clip), plus the DRX-9010 Driver Extreme premium external speaker and the DRX-6560 Driver Extreme 4-pin noise-cancelling dynamic microphone.

Is the DRX-6560 a plug-and-play replacement for the Cobra 29 LX stock mic?

Yes. The DRX-6560 uses the standard Cobra 4-pin pinout and plugs directly into the Cobra 29 LX's front-panel 4-pin microphone jack. No adapter or wiring change is needed.

Do I need a special adapter for the DRX-9010 external speaker?

No. The DRX-9010 has a 3.5mm right-angle plug that goes directly into the Cobra 29 LX's rear external-speaker jack. The internal speaker automatically mutes when the external speaker is connected.

Does the DRX-6560 need batteries or phantom power?

No. The DRX-6560 is a dynamic microphone — no batteries, no power source, no phantom power required. It draws its signal from the radio's mic gain stage.

Do I save money buying this combo?

Yes. The combo is priced at approximately 5% below the total of the three components bought separately.

How much better is the DRX-6560 versus the Cobra stock microphone?

The DRX-6560 is a noise-cancelling dynamic microphone with an internal breath-pop diffuser, tighter low-frequency roll-off (55 Hz), and proximity-effect compensation. In practice this means less cab noise, less blower rumble, and cleaner intelligibility on the receiving end — especially at highway speeds or in older trucks with more ambient noise.

Can I keep using the stock Cobra mic if I want to?

Yes. The stock microphone is still included with the radio. You can keep it as a spare or use it interchangeably with the DRX-6560 — both plug into the same front-panel 4-pin jack.

Is this the same audio setup as the Cobra 29 LX-BT?

The audio upgrades (external speaker + noise-cancelling mic) are similar in intent. The 29 LX-BT adds Bluetooth for hands-free calling, but its CB audio path is very similar to a stock 29 LX with a wired mic + external speaker upgrade. This combo delivers the audio upgrade without the Bluetooth premium.

What other radios does the DRX-6560 work with?

The DRX-6560 works with any CB radio using the standard Cobra 4-pin pinout — the entire Cobra 29 family, General Lee, most Galaxy models, RCI, and many others. If your radio has a 4-pin front-panel mic jack, the DRX-6560 is likely compatible.
