OUR BEST SELLING SPEAKER JUST GOT BETTER!
MEET THE DIAMONDBOXX L3neo
Our best-selling model just received a no-compromises upgrade.
We transplanted the flagship XX4’s neodymium dual-voice-coil 8.5" woofers into the L3. You now get:
- Deeper, tighter more authoritative bass
- 4 lb weight reduction (now 27.5 lb total)
- Higher efficiency and added power to the titanium-dome tweeters to blend
The result is the best-sounding L3 we’ve ever built.
Everything else that made the L3 famous is still here — only better:
- True wireless stereo pairing
- 121 dB of clean, undistorted output
- Dual 8.5" woofers + 4" tuned port that delivers physical bass impact
- Tri-amped 300 W RMS (600 W peak) Class A/B amplifier with active crossovers
- 2 amplifier channels drive the tweeters, another 2 channels drives one coil of each woofer with the midrange signal, and the last 2 channels run both voice coils with the subwoofer signal
- Massive machined aluminum front panel doubles as the heatsink → runs flat-out in the heat without ever throttling back
- Rechargeable lithium battery new 21700 cells→ 5–26 hours of playtime, 10 years life expectancy
- Plays indefinitely while charging with included charger
- Bluetooth 5.1 aptX HD + 3.5 mm analog input
New fine-textured anodized aluminum finish resists fingerprints and looks sharper than ever.

Size: 23 × 14.5 × 9.5 in
Weight: 27.5 lb
Frequency response: 38 Hz – 22 kHz (±3 dB)
The L3 remains the biggest performance-per-dollar in our lineup. For most people, it’s more than enough sound to dominate any party, tailgate, or beach day — and still have the neighbors reaching for their phones.
