OUR BEST SELLING SPEAKER JUST GOT BETTER!
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.

Customers praise this Bluetooth speaker for "incredible" sound clarity and "insane" bass that "blows the competition out of the water." Many describe it as "the best" portable speaker available. While sound quality earns consistent acclaim, some note delivery delays and a few experienced charger issues. Battery life at max volume averages 5-7 hours vs advertised 6-8.
PASUB15
The PASUB15 was purchased to compliment the existing M3, currently used in my vehicle, as a use-as-needed application, to retain the storage/transport function. The PASUB15 represents a great value compared to the cost of installing a separate amp, subwoofer with enclosure and installation of wiring, and retains the dual function of operating outside the vehicle as needed. While the PASUB15 does provide the low end performance as expected, it lacks the 'quality' of the M3 low end response. Next, I will try different orientations of both in the vehicle in hopes that will improve the response. When not in use the rear seats are brought up and the cargo cover hides both from public attention. The SUV cargo cover bar also serves as a brace against PASUB15 forward movement during braking. The bungee cords, using existing tie down rings, combined with some stuffing prevents the units from drifting while driving.
Model L3 (B-Stock)
A small blemish in the powder coating is all it took to classify this as a “B” stock unit. Works as good as my other L3 I previously purchased. If you’re looking into a “B” stock unit weather it be to receive it sooner or to save a little money, don’t hesitate!
I have 4 XLs, 2 Ls, 2 L2s, 2 Ms. Will be getting 2 M2s. Completely Right ON. Enough talk... listening to Marika Rossa
The sound of the L2 is awesome; I have the Model M and thought that sounded good until I cranked up this L2! The mids and highs are clean and crisp as expected from Diamondboxx products, but the lows on this L2 are pleasantly deep and clean! That in itself deserves 5 stars. Homerun right?? Well the thing I am fretting about is the Bluetooth on this unit.. For some reason the Bluetooth connection on the L2 is not as strong as the Model M? With the Model M, I can walk 20-30ft without a problem. Behind a wall or into another room? No problem! With the L2, there is a lot of breakage around just 15ft.. I find it pretty strange. If it weren't for this Bluetooth problem, this would be a solid 5 stars
I received my Panda L3Neo and I must say that the wait was well worth it! I'm already planning for another so I can have a matching pair.
I could not believe how clear, loud this boxx is! And the bass is insane! I just ordered a second one! I cant wait to link these together and blow up the noise ordinance! This blows my Bumpboxx Lifstyle away, not even close!!
Absolutely worth the wait. Words can’t describe the clarity and the loudness that the L3 produces. This is on a level that you can’t comprehend unless you hear it in person. Hats off to the team at Diamondboxx. Well done y’all!!
I have my box now and it has surpassed my very high expectations. I will start by reiterating that this is a small company who is trying to meet high demand. I was frustrated waiting for delivery but against some advice the sound junkie in me told me to be patient and with the patience comes the rewards. This thing is great, built like a brick shi_house, quality just oozes from this box. My backup is a box built by a company that tried and unfortunately failed to resurrect an old audio name from the 70s, 80s, and 90s. It is an excellent box but moving from a building with high ceilings to low ceilings, the sound was suppressed so I have been heavily eyeing diamondboxx for several years. I finally relented and my god I’m so happy I did. This is about as big as you can get and still be truly portable meaning transported daily not occasionally. The quality is second to none, it surpasses my old excellent box easily. The bass and sound are perfectly matched. I don’t normally have to go past 60-70% but on a favorite song I can crank it as far as I want with no clipping or overdriving. The bass is not like the guys you hear driving down the street with 10,000 watts going to their subs and 200 watts of sound going through crappy speakers and seat reclined with their arms straight out, total garbage. This is very balanced with plenty of headroom to increase the bass if you ever need to. The battery does just fine considering the power which is very evident if you stand in front of it. If I had the option of giving this more stars I definitely would. Keep doing what you do for the true sound lovers, your work is incredible.
I received my L3 a week and a half ago and have been listening to this thing a few hours minimum every day since. I've had a thing for bluetooth speakers for a little over 15 years now starting with the Kicker ik501 back in '09. I currently have a pair of Aiwa Exos 9's, a Soundboks 4, and now this Diamondboxx L3. I can say with certainty this L3 sounds above and beyond the best. Reminiscent of when I upgraded from the Kicker to the Aiwa, you immediately notice all the little details you've been missing with other speakers. In terms of overall SPL/Loudness, the Soundboks is a tad louder, but not nearly as much as you would think. This has the most detailed and accurate bass I've ever heard and gets deeper than you would think. Deeper than both the Soundboks or the Aiwa. Listening to instrumentals with High Quality lossless music via aux will give you the chills. It sounds great over bluetooth, but even better with the aux cord. If anyone has anything bad to say about this speaker's sound quality, either they don't know what they're talking about, or they have not actually heard one in person. It was everything I expected it to be and more. Well worth the wait, these guys clearly know what they're doing and take great pride in making a QUALITY piece of equipment.
Listen, I love the product. I have five DiamondBoxx radios. They built great radio with great sound quality. My only issue with DiamondBoxx is customer service when there is a problem. It takes a very long time to get a response and sometimes when they say you will receive a product before a date that doesn’t happen I’m in military family so we try to keep things in a timely fashion and in order. I wanted to purchase another L model, but I’m afraid I won’t receive it when your website says it will be available me. I just think it would be very helpful to that. The customer know what’s going on and give them the option to wait that long period of time when spending that kind of money.
I’m not going to bash these guys as I’m realizing that they are a super small but very passionate group. I ordered on December 18 and in late December the shop app said my package was delivered which it wasn’t. I tried to contact every ups number I could find but it got nowhere as I needed to have an ups tracking number to speak to a human which I didn’t have. Not a fan of the shop app. I have been in contact with diamond box who have been very nice, they seem to respond to messages at the end of the work week as I’m sure they’re busy. Still waiting on my delivery and it’s killing me as I’m a sound junkie. I have no doubt they are legit and I have no doubt my L3 will be amazing.
I had never heard of Diamondboxx before until this past summer when a coach was using it at the baseball field. I could not believe the sound that came out of this thing and I fell in love with it immediately and knew I had to have one. It is so clean, crisp, and full of robust bass and sounds even better in large spaces and outside. I played it out on in the backyard and you would have thought I had a concert here if you were walking by the house. I cannot even phantom what the large models sound like but this one is perfect for all of my needs. Very happy!
Ordered on 12/17/24 excited to get my hands on this. My coworkers sold me on this. The sound and clarity was so amazing I ordered right then and there. I anxiously keep checking my email everyday hoping to see a shipped update soon!
Love the treble clarity at high level volumes! Bass hits hard and doesn't drown out lyrics. Asked for Orange knobs as opposed to the Blue but they shipped Red. Only complaint. Hoping they send me a set of White knobs from this review, so that I can have the ol' "RED, WHITE & BLUE" theme!
Sound clarity and bass are incredible. This thing is LEGIT and makes all other brands look like children's toys.
I’ve read a few negative reviews mainly about the product not being delivered on a timely manner. You have to understand that Diamondboxx is not like those big company where their products are on an assembly line made of plastic. Please pay attention to their website on why there is a delay. I myself have encountered a problem with my order and diamondboxx is going to fix it. Patience people!! I have their 1st gen M3 and i’m still rocking it. The best sounding portable bluetooth speaker. I can’t wait for my L3Neo to properly work.
I have the L3 about 7 or 8 years ago is the new L3 neo a big difference from the original! I'm very happy and blown away with my original L3 could explain the difference between both speakers 🔊

I recently got the L3NEO and honestly am totally blown away. The quality of the sound is excellent, the bass is super deep and powerful. 10 out of 10 blown away. Really awesome, and definitely recommend it
Excellent speaker does what it does still haven't fully broken it in yet( can't wait for that so I can hear it full volume) but overall very satisfied . Hopefully shipping is nice to me and I can get the xl3 nx time around
I've owned many boom boxes. The DiamondBoxx L3Neo is the best of them all. The build quality is solid, it looks great, is light, and sounds incredible. This box is expensive, but truly worth the price. Beats any box out there in my opinion.
L3NEO - Loud Enough for a Big Party, Bass You Can Feel, Only 28 pounds!
Like the title says, I was blown away when I received my L3 NEO. It is a big solid unit I didn't expect this level of quality materials and sound. It is loud enough for a big party and light enough to move around easily
Best wireless speaker ever
L3 300 Watts RMS 8.5 inch DVC woofers
Turn heads and drop jaws while you play this at obnoxiously loud volumes with a fidelity people didn’t know they needed till they hear this speaker.
Probably sold three+ speakers at the first party I brought this to.
Beautiful looking and just amazing sounding speakers! Robust build, extremely clean, 100% blemish free. Love the Panda finish. As a stand alone, one L3 is you will ever need. So of course I bought two, and together it's just other worldly. Can't wait for my pair of XX4s to arrive!!
good
