...Just remember nobody builds this shiteee to break even so it probably only cost half as much to build as what they retail for. I dont mind paying for something that's a good deal but that price will leave your ass hurting .
A quick search on the smaller battery option (4S3P 2600mAh Samsung) reveals that the battery pack can be purchased as low as $2.80 USD. Cycle life for the battery pack is approximately 500 times. :hmmm: So, after 500 charges, the batteries can start to fail or at least lose a lot of their capacity.

2600mAh makes me think that Diamondboxx cheaped out because I have 18650 batteries in flashlights that are 3800mAh. Granted, I'm using single batteries whereas the Diamondboxx is using several batteries bundled in a pack.

Still, I would love to hear one in person.
The DiamondBoxx M3 has two battery options. The smaller option which is 4S3P 2600mAh Samsung actually means 4 cells in Series, 3 sets in Parallel. So it has 12 X 2,600 mAh cells all connected to a custom circuit board which monitors the 12 cell pack for overvoltage, undervoltage, cell balancing, over current discharge, over current charge. Not $2.80 USD, about 20X that. The DiamondBoxx M3 with large battery option has a 24 cell pack with its own custom control circuitry. We have been selling DiamondBoxx for 5 years, thousands of units in operation today and have since replaced maybe 3 batteries.

Funny thing about Diamondboxx is that the owner, or someone employed by him, harrasses people on YouTube who say anything critical about their radios. He also goes on other people's videos and writes comments saying how their radios suck and Diamondboxxes are better, etc. That's a shiteeeety form of marketing if you ask me.
That probably isn't anyone who is officially connected to our company, as I have been the only person representing our brand on social media, at least 90% of the time anyway. Admittedly when someone doesn't have their facts straight I will help them, but I would never submit opinion. We are a bunch of stand up guys here at DiamondBoxx, ex engineers from other major audio brands, several patents in our repertoire. This isn't a get in, rob people and get out kind of a deal for us.

Very honestly we have a pretty tough job, we are trying to do what 95% of companies in America failed at. We are designing our own circuit boards, amplifiers, and speakers. Machining aluminum on a CNC, and hand assembling these one by one, in California of all places! Then selling them at a low enough profit margin that would make it impossible for anyone to compete with a similar business model. This of course leaves the door wide open for others to copy the concept, including marketing strategies and naming conventions and ship containers of Chinese knockoff to the USA to sell at a much lower price point. If all we had to do all day was market and sell we wouldn't know what to do with ourselves and maybe I could find time to talk s about other products, but we choose the manufacturing route because that is what we know how to do. Personally, I don't have time to harass people on youtube videos, nor would enjoy doing so. I'd rather be designing the amplifier for the up and coming DiamondBoxx Model L3, or amplifiers for our super high end D'Amore Engineering mobile audio brand, or electronic tools for installers of audio, or home amplifiers under the same brand. Which is what I need to do now.


The biggest bass in the business, all of our models. The M3, the XL2 and the coming L3. https://www.youtube.com/watch?v=NvhxtoL0D3g

I still think its ugly. Sorry to those who love. Just my opinion.
Ditto. Fugly beyond belief IMHO

It looks like a high school science project made from scrap pieces found around the house. Given it's suitcase like chassis, I don't know why they just didn't model after a Marshall guitar amp. It certainly resembles the amp construction better than a boomer
The looks are personal preference of course, but wow did you have a CNC machine in your high school?


Speaking of our other models, here's a gutshot of the XL2 showing our custom neo drivers and extensive aluminum bracing of the .190" thick 6061 aluminum panel


That's got to be one of the best highest quality speaker arrays I've seen. No doubt the quality is there. I've never seen these pics but I will say that's impressive.

These diamondboxx machines are the real deal! Big $$$s but hey, you’ve got to pony up the dollars if you want to play with the big boys. Not a huge mass market at their price point as most consumers just aren’t prepared to pay for quality. So all we get offered by most manufacturers are flashy looking **** boxes with rotten insides full of the garbage parts to get the price down.

These Diamondboxx guys are awesome. :-)

These Diamondboxxes are O.K...but they're not worth the money when it comes to blasting music. You can do much better for the same amount of cash.

The dude's name is Brad Rawsner, he spams videos of old-skool boomboxes, telling everyone that the new Diamondboxx L3 would smoke it (like as if we didn't know that a modern $849 speaker would crush a 40 year old, 20 watt boombox). That's when he's not posting right-wing conspiracy theories.
