XL Retro: The Ultimate Fusion of Classic Power and Modern Innovation

We're crafting a limited edition run of the XL Retro because our community demanded it. We've revived the iconic design of the original XL, complete with its legendary exposed woofers—no integrated grills here, so you can witness the full flex that made the XL famous. But we've supercharged it with the cutting-edge features of the XL3, including a 5-band EQ, adjustable stereo image control, and Bluetooth 5.1 with aptX HD support. It's the perfect blend of vintage vibe and contemporary performance.

Experience Wireless True Stereo Sound with customizable stereo width control for an immersive audio landscape. Powered by six meticulously hand-matched (for T/S parameters) 5.5" woofers and a 4" bass port, the XL Retro delivers bass you can feel in your chest. Crank it up to an ear-shattering 122dB at 1 meter—all driven by a robust 16.8V 15Ah Lithium-ion battery. Take your playlist anywhere, anytime, with no power outlet required.

At its core is a built-in 600W RMS (1000W Max) Class A/B 10-channel high-fidelity amplifier, configurable in tri-amped or bi-amped modes. It features 2-way (SPL MODE) or 3-way (SQ MODE) active crossovers and analog signal processing, optimizing sound quality in the lightest possible package while maximizing battery life. With zero-latency inputs, it's ideal for video syncing without any delay.

Engineered for endurance, the XL Retro's massive aluminum front panel doubles as the amplifier's heatsink, ensuring it performs at full blast all day—even on scorching hot days—without missing a beat.

Beautifully Crafted

I love my JBL Partybox 300. So I was skeptical If the Diamondboxx could get as low with the bass, since I have been really impressed by the JBL. The first thing I did when my XL2 arrived was a sound comparison. I'm blown away by the Diamondboxx. It sounds wonderful, is all I can say. I'd buy it again. It legitimately looks and sounds premium! It's really in another league. I still think the Partybox 300 is impressive for the price range. But if you want the best sound in your portable Bluetooth speaker, look no further than Diamondboxx!

...an avid and loyal Diamonboxx customer

Where to begin, Ive been researching different Bluetooth speakers and doing comparisons side by side for about a year now. Topics that were important to me were sound, sound quality on the highs, bass loudness, price, battery power, and durability. Ive researched every speaker under the sun…trust me, EVERYONE! Hands down. I settled on the XL2. I began my purchase in July and its been nothing but a great experience. Im a ‘ask questions kind of guy and I was spoiled with quick and accurate responses from Julie Freedman. Shes adds to the greatness in quality from a customer service standpoint. DB uses shop.app for a seamless experience in shipping and tracking in real time. Now, Christmas in July. Per the app, I knew when my XL2 would arrive. Even during the pandemic, Diamonboxx delivered a pristine product in great timing. The box came and it was glorious. I hook up the XL2, the Bluetooth connection was faultless. The sound quality is superb. From the highs, to the mids down to the bass. There is 0 loss in sound quality at max volume. I went to the second floor of the condo and I could feel the bass through my feet. I love it. I am an avid and loyal Diamonboxx customer for life. My next purchase will be two P15s and another XL2. Cant wait for that and cant wait for those reviews.

Best Investment

I previously owed 2 UE Booms (2014-2015) BrookStone Big Blue Party Speaker, (2015-2020) heard the JBL and seen a SoundBonks a handful of times. But never have I heard or seen the brand DiamondBoxx. Not many reviews are out as this business is small but one day I hope to see you guys up there with the top dogs. I was looking for a speaker for work to enjoy music as the night passes on. And let me say. Is this the speaker. Hands down a must buy, sure the price is hefty but itll pay itself off, go big or go home. Ive never heard anything this beautiful on a speaker before. Its literally got everything that a home surround sound would have, from the voice to the bass and the fact that its a portable speaker makes its life a whole lot more interesting. The DiamondboxxXL2 is truly a piece of art to be reckoned with. I appreciate the business and am looking forward to youre future products. Keep up the good work, speakers are sounds better than whoever did them.

Ultra powerful speaker

This speaker is the best battery-powered speaker on the market ! Good points: - It is so powerful that 60% of volume is enough for it to be already very loud ! - The bass is incredible for a transportable speaker. - The sound is very clear and precise without distortion or audible saturation - The battery (462wh) is sufficient for a very long (and loud) party. - The speaker is very beautiful (especially in blue) - The quality of manufacture is really good. Negative points: - When you put the volume high enough a metal noise that vibrates you hear when you approach (I think it could come from a woofer grid) must see how it will evolve in the future... - The plug for recharging had arrived folded and I tried to fix it by folding it back a bit I managed to plug it but the thing that is around and at the end of the cable when I tried to unplugged it the thing broke now the cable is less well held. - The range of bluetooth is not excellent (do not move more than 5 meters otherwise there will be bugs)

Two are better than one!

Totally impressive to all that have seen and heard my pair of blue XL2s. The commit I hear the most is, “they sound so clean”. Im greatly satisfied with this truly well built product.

I love it! As soon as my family heard it they were amazed at the clarity of the 8 tweeters and the 6 woofers! The bass is very precise, smooth and crisp! My father has a JBL boombox and my XL2 blew it away! Tons of people complain about the price I know because I was one of those people but let me tell anybody thats maybe thinking about it if you dont have the money theres other good speakers! But if money isnt really an issue please I highly recommend the XL2 because not only was I blown away but so was my family! Diamondboxx thank you!!!!

Wow! It sounded great when i first turned it on but after a few days playing music it seems to have broken in the speakers and sounds even more amazing!!!! The quality/craftsmanship is amazing. Lots of attention to detail. Everyone from conservative to down to earth loves it; Im tasked with supplying the music to everyones barbecues next summer. Thanks so much guys (and gals) you put together a great product and the passion for what you do really does show. Dj Dave The One Mendez

One XL2 is great..

..but two XL2's is something else! Greetings from Norway! Due to a DHL mixup I received my XL2's one day apart from eachother. Obviously I had to test the first one the second I got it unpacked and I was pretty blown away. I prefer bass heavy music and it just ate up everything I threw at it. The bass is awesome as stated many times elsewhere but the punch this thing delivers is something else. It brings the mind back to big car sound systems where you can feel the kick hitting in your chest. I played indoors, took it out on the balcony and even in the back seat of a car. It's good all-round but weirdly it sounded the best when I was standing beside it out on the balcony. As if saying "This is where I belong!" But I soon found a good placement for it inside as well. The next day I received the other one and my experiments continued. And this is the interesting part. Because I purchased these to replace my dual Devialet Gold Phantoms. So there was a lot of A/B'ing back and forth finding the differences between the two. The Phantom wins at the lowest sub bass and in the highest treble. Not by much, mind you, but I could hear a difference. The XL2's kick ass all the way inbetween though. The Phantoms are high-tech high end delicate pieces of modern art while the XL2's are just raw power and FUN. Plus, the XL2's are portable and battery powered, which can't be said of the Phantoms. Cost wise, they're comparable although the XL2's ended up being a lot more expensive due to toll fees. I might still be in a honeymoon period with my purchase but I'm very pleased so far. I'll be recording some side-by-sides and put them on youtube before selling my Phantoms. They are paying for most of what these XL2's cost, after all. And I can't wait for summer to come so I can bring these bad boys out to play. In the mean time I'll be having a lot of fun with them in the living room. regards Timo
