Very cool looking machine - I can just imagine the bass that little box would put out!! I’ll never be able to afford one though that sucks I suppose. 
Nobody said it looked cool when compared to a vintage Boombox but man, the quality and quantity of sound is astounding. Bass production a vintage box can only dream of producing. 200 AB amp watts RMS compared with what, 3-12 watts per channel from a classic box?MesaAZGuy said:
That’s why it’s cool.
But yeah, it’s no looker!

Another over prices amplified speaker box. It seems like they refuse to make anything attractive looking and that price is insulting. If it's so damn loud why can you hear the guy talking over it lol. Sorry utter pos. I almost feel sorry for anybody that thinks its cool but if you have almost $600.00 to blow go for it.
I'm not against everything but new and ugly go hand in hand these days.
I'm sure their greatest minds were put to work coming up with a box with some speakers and a battery.
I mean even the name reminds me of some of the tacky ass jewelry and diamond teeth lil john has .
if I had $600.00 to build a box it would smoke that pos off the face of the earth. Just remember nobody builds this **** 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.JVC Floyd said:
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.

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 shitety form of marketing if you ask me.

I think everybody that promotes these on YouTube is a shill that has ties to the company .
I would enjoy kicking that dude in the head with a pair of steel toe army boots then stomping a mud hole in his precious diamond box. That whole video just annoys the hell out of me , and that candy ass douche bag talking makes my agent orange act up. Guys like these are the reason the bitch slap was invented.

Ditto. Fugly beyond belief IMHOMesaAZGuy said:
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 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.Fatdog said: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.

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.Reli said:
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
The looks are personal preference of course, but wow did you have a CNC machine in your high school?Brutus442 said:
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
Here's the link where I saw that price. You might want to check them out and maybe save some money.DiamondBoxx said:The DiamondBoxx M3 has two battery options.

By the way, I'd still rather have a DiamondBoxx than a bumpboxx. Thanks for still being around and keeping DiamondBoxx alive!
. I do plan on getting a smaller DiamondBoxx
