The SUB8.2 put my sound system over the top!

Model SUB8.2 (B-Stock)

Absolutely sick. This B-Stock SUB8.2 connected with the XL3 is a literal nightclub in my home (complete with vibrating windows and picture frames!).

A must have subwoofer

I have a L3, XL2 and a XL3. If you have any one of these, I know you think they have enough bass. but the sub8.2 takes it to a whole different level. When I was watching the videos, I was hearing the same. It don’t make any difference which Diamondboxx or Bluetooth speaker you have. The SUB8.2 will take it to the next level.

Next level bass!

I ordered my Diamondboxx sub8.2 all the way from the states to South Africa and was well impressed with the service and speedy delivery. I had expected to ages but its here 2 weeks later and wow it sounds amazing with my other battery powered speakers. Don't even think I've pushed it past half way cause i worry about my poor neighbors. I also didn't know i was getting a diamond but hey it just adds serious class. Thank you Diamondboxx worth every cent!!

Perfect balance of sound

I paired this with my M3 speaker and they compliment each other perfectly. Love the control of bass that the sub8.2 offers. When it arrived it came very well packaged, it was double boxed and it was very well insulated. Highly recommend.

Lx3 aux inputs bad quality

Not sure why my LX3 blew up on me basically low end 1st went from bad to worse then the tws using the auxx inputs they shake they're loose and they're clearly made bad connections cheap for such an elegant box

Line output

Only issue with mine was line outputs do not properly work leaving the Bluetooth part of it useless, I have to use a splitter with main speaker to line in. Contacted customer service, but I also don't want to send it back and forth.

Great product, defective outputs

SUB8.2

Great build and sound, does exactly as it's supposed to, however one small issue for me is the output ports for hipass or full do work.

I plug the auxiliary port in halfway and it sounds right but is quiet, plugging it in all the way doesn't allow for sound to be sent out.

It doesn't bother me too much, perhaps I have a defective unit, but the outputs should be operable, to fix this I use an audio splitter.

Sounds very clean with a strong deep low end

SUB8.2

I have a L3 and was amazed with that, now pairing it up with the Sub 8.2 is quite an experience. Ordered it and it came within a month or two, as expected from a custom built system. Very good quality, and is also heavy like the L3. The Sub is very punchy on rock and metal style music, listening to rap, it will easily hit basically every note besides where it cuts off as expected, like 30-28 hz it plays to, just need more volume. The bass boost is at 40 hz, so it will make kick drums more attenuated. I figured it would boost more low end below that, but it doesn't do as much as expected in that regard. Very impressive for 200 watts, feels more like 300-400 but once you hit the limiter, you will be left wanting more because it sounds so dang good for 8.5 inch drivers. When you crank the Sub with the L3, (wired to L3 through full output with Bluetooth paired to sub) it shakes the walls in my room and rattles the door which is on the smaller side, 11'x13'. Put the two in the shop at work, and it sounds really good, but you will hit the limit of the Sub really easy. For most volume, you should obviously have bass boost at 0 db and use the volume accordingly. I've noticed for the crossover, for my room, I really need to have the Sub crossed over at 50-60 hz with the L3 or the midbass can be overpowering, but that's probably due to the speaker size and their resonant frequencies. Lastly, I have hooked up my L3 and Sub to my other 12 inch passive mtx subwoofer powered by a computer power supply and a skar audio 1200.2 monoblock and wow... That combination of speakers actually has me worried sometimes with the violent shaking that it can cause to the walls. Definitely worth it since I also purchased it while it was a couple hundred off..

Got my L3 and wow it is awesome! The punch and the Clarity is amazing. By getting the M3 first I needed that the materials and the Box itself was amazing but wow when you turn the volume up on this thing it is awesome. It is loud and clear with great bass. I have a lot of different boom boxes and this one here is the best! It more compared it the partybox speakers with a more refined fuller sound.
Can't wait for the next step and that is my Sub 8.2 coming in. Dimondboxx Rocks!!!
