Finally a video talking about both exos 9 and diamondboxx. According to him, the exos 9 is boosted for bass and lacks a little bit in mids and highs (still good but inferior to the diamondboxx who has flat natural sound). The diamondboxx is a lot louder, some claims as loud as 4 times the exos 9. The build quality is a lot superior with the Diamondboxx and there will be a video comparing one diamondboxx versus not only one, but TWO exos 9. So I guess from that point we will be set about the real value of those 2 boxes quality&sound/price. Can't wait for the next video

Keep in mind that "louder" boxes usually have less bass, especially at indoor listening levels.
For example, a JVC M70 is plenty loud, but its bass at low volume levels is kinda "meh". The Crown 980 is the opposite.
Always compromises.
Also I don't think you can link 2 Diamondboxes together for L+R stereo effect, like you can with a couple Aiwas.

there is some videos showing many diamondboxx link togheter I will post one below, one has claim you can link up to 25 and the engineer (I think) Tony has claimed up to 100.

as for the low volume bass I have no idea someone who actualy has one could answer.
...but the way I see it, if you crank the boombox all the way up and keep your portable mp3 device low, it should allow the boombox to give its best bass. Maybe I am wrong but with the DT680 I would always use maximum volume and bass enhancer, and only play with the mp3 volume for best result (plug in the front mic).
now imagine someone near has a portable mp3 full volume with bad intention and get access to the bluetooth connection of one of those monsters, ouch. The surprise. :scream:

So the real question is what's important to you? Is it the look, style, street cred that's most important? - (as you're sensitive to what other people will think).ScareDe2 said:Finally a video talking about both exos 9 and diamondboxx.

Or is out and out performance your thing? (and to hell with what people think).
If you want the best sound possible, then don't even look at department store consumer products. Mainstream manufacturers need to make money and they won't do that by giving you the best components. Products that look good, are cheap to make and thus easy to sell is what the market is full of.
Compromises have been made to help the bottom line and we, consumers have to settle for what the company accountants think we deserve.
The DiamondBoxx is probably the closest to a custom box as you'll ever get. An example of this is that genuine alloy front plate (most cheapo brands would substitute it for chromed plastic). They ask big money but the quality of the amp, speakers etc and the MDF cabinet costs money so the consumer pays. (Fair enough) Why many BT manufacturers refuse to give you tone controls on a BT speaker is beyond me.
The Exos-9 is a fantastic concept and for the little money they ask, the Aiwa has to be the best value BT box out there!!
However, if you think a RX-DT680 sounds great, it won't even hold a candle to what a well designed DIY box is capable of. Don't believe me? Try it for yourself. It won't be cheap though. My latest V5.0 box cost me $496 AUD in parts alone. Keep in mind though that $500 won't give you access to the rarefied air of 'high end' retail BT speakers anyway!
In relation to the above video, when did it become best practice to test audio products at maximum volume with a decibel meter?? Such a bull crap test.
If you just want oud, then do what Pioneer did with the DiscoRobo and forget about power sapping bass. Just install 4 mid speakers, no tweeters and crank that combo to 109dBs!! Loud for sure but very fatiguing to listen to!!
I am not searching for a good looking radio to walk the street or impress the girls 
I could not guess that an Aiwa exos 9 was a better sounding unit than the JVC M90, so I am very thankful to the members here who help me know about it. I thought vintage was best and todays boxes were absolut crap (even if they have huge power).
Yes, I want best possible sound from a box. I don't want pre-boosted machine or a boombox lacking mids and highs. I want guitar distortion reproduced with fidelity.
Now that I know the Aiwa is pre-boosted and that an equilazer lessen the sound quality and that it gets killed 1v1 by the DiamondBoxx, I seriously think I should break the bank and go for that big one. The DiamondBoxx cost huge money but still less than a good working JVC M90 (lot less). The DB specification says it performs great at low volume and high volume. At this point it seems it's the best sounding boombox on earth.

Maybe the best 'commercially produced' Boombox. I prefer the standard Boombox style bass and treble controls with no software driven presets.
Each box will have its own natural tone. With bass and treble controls set to flat, my V5.0 box leans on the bassy side due to the size of the drivers and speaker cabinets. In other words, you don't have to boost the bass and treble levels to make it sound great. That is a well designed setup in my book.
Modern BT speaker buyers aren't like HiFi buyers though. How many HiFi buyers would judge the performance of an amp by how it sounds at max volume?! BT box buyers will mark a box down if it shows any sign of distortion at max volume! So what do manufacturers do in response? - They give the buyer no tone controls and they throttle back the bass as you turn up the volume to avoid distortion. They treat the user like a baby who can't be trusted not to blow up the speakers with excessive distortion.

They challenged everyone to build a unit for the same price and reach the same specs. If someone can make it he will receive a DiamondBoxx for free. As far as I know no one did it. And how do you home-made an amplifier who can meet audiophiles requirements?jimmyjimmy19702010 said:
Never heard of that challenge. What specs do you have to match? Case size, weight, speaker size, tweeter size, amp power rating??
I can say that if I was forced to make an equivalent DIY box to DiamondBoxx specs with little drivers etc, then the DiamondBoxx would win that comp.
But if I was allowed to use traditional size 8 inch HiFi speakers and a sealed cabinet design that follows traditional HiFi guidelines, then yes, a V5.0 box with 8 inch drivers, Krix silk dome tweeters with Krix matched HiFi crossovers will kill a DiamondBoxx.
The sky is the limit with a custom box - I could select any amp, any speaker any crossover I wanted. With that flexability, are you still sure a DiamondBoxx will be superior?
But in saying that, it's not really a fair comparison. Size matters in audio and big drivers will tend to be more efficient and require less boosting to sound fat.
The DiamondBoxx is much lighter and smaller - I can't compete on that front.

Go get your DiamondBoxx man - I'm sure it will sound awesome! It's quality gear for sure and it will crap all over any vintage box in the performance stakes. Please do a review when you get it - I'm sure there are plenty of punters who'd be very interested in a Boombox enthusiasts opinion.
Peace,

Yep, as I thought. Those guys at DiamondBoxx are pros and I'm sure they've squeezed ever bit of performance possible from that combo.ScareDe2 said:From the DiamondBoxx facebook page:
I understand that you need to keep it in the same weight division and meet the same specs measured by precise instruments.
Personally, I don't mind a bigger and heavier box. But the guys at DiamondBoxx are competing with small, plastic BT speakers and as such, weight and size limits are critical to the success of their business. 9.0 kilos (20 lbs) is pretty light considering its performance potential.
All very understandable really.
It's a 180 degree turnaround from the 70s when heavy meant quality to buyers!

The only thing I don't like about the Diamond box is those ports. If you look on their website you'll see photos of its construction. Looks like the ports are simple ABS tubes you could buy at Home Depot. No shaping whatsoever. If you look at a high-end home speaker, its ports are flared to be more aerodynamic and reduce turbulence.
Here is another interesting box. Kinda small, but top-notch quality. 7 speakers plus 2 passive radiators, 154 watts total.

There it is the comparison between TWO Aiwa Exos 9 Vs. ONE DiamondBoxx. Freshly posted a few minutes ago.
https://www.youtube.com/watch?v=tC_4IBFEx-Q
What I understand in this video is that the Diamondboxx is LOUDER than TWO AIwa Exos 9 and seems better for indoor listening however TWO E9 have a nice stereo effect outdoor. DB has a high fidelity sound reproduction in all fequencies where the E9 is more boomy, more bassy and lacks a bit of mid range and highs.
So the DB is worth every penny if you care about loudness, sound reproduction and quality.
Here's a guy using the DB for car system:
