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.

The sub is great for my usage and has an excellent build, however, the line outs are inoperable and they are quiet when plugged in halfway and do not work when cable is plugged in completely. I tried different cables and the ports appear to be the issue. Other than that, which I bypassed by using a splitter, a great product.

The PASUB15 was purchased to compliment the existing M3, currently used in my vehicle, as a use-as-needed application, to retain the storage/transport function. The PASUB15 represents a great value compared to the cost of installing a separate amp, subwoofer with enclosure and installation of wiring, and retains the dual function of operating outside the vehicle as needed. While the PASUB15 does provide the low end performance as expected, it lacks the "quality" of the M3 low end response. Next, I will try different orientations of both in the vehicle in hopes that will improve the response. When not in use the rear seats are brought up and the cargo cover hides both from public attention. The SUV cargo cover bar also serves as a brace against PASUB15 forward movement during braking. The bungee cords, using existing tie down rings, combined with some stuffing prevents the units from drifting while driving.

Overall very good experience. The only issue was shipping and handling which is beyond their control. The box and interior showed that it was dropped and holes along the sides indicated mishandling. Yet the unit survived in tack. One minor nit was the AC cord plugging into the unit. It took a little more effort to insert and does not seem to mate properly. I will locate another AC cord and see if that mitigates the issue. Outside of that cord there are no other cables supplied, but that was not a show stopper. Sale price helped to increase the value of the unit.

Excellent unit love the quality and sound..Only thing I wish it had a battery that wasn't hardwired and could be swapped out easily...Also my plug to charge is coming undone.Do yall sell replacement charger for the M3? Great sound I'm particular w my sound...

Didn’t think it would be as good as is. Shakes the house and can be heard from the outside, definitely gonna get another one

A small blemish in the powder coating is all it took to classify this as a “B” stock unit. Works as good as my other L3 I previously purchased. If you’re looking into a “B” stock unit weather it be to receive it sooner or to save a little money, don’t hesitate!

Great product until Diamond box sent me out a defective sub. When I emailed them about it, they told me I had to pay to send it back cost me almost $200. Then when I question it, they told me I should’ve been issued a RMA too late. I already sent it back.

I’m proud to be owner of this hi quality equipments, i purchased 4 units, Two XL3 and Two 8.2 subwoofer. The sound quality of the speakers always makes me say while I’m listening … WOW I really did a good investment on this purchase… Instruments that I never noticed on a song , now I can hear them cristal clear ,. I’m glad I ordered my 4 units at once , the reviews of people talking about Diamondboxx was true , the best sound system I ever had , I can take it anywhere and enjoy of it’s amazing sound,. I’ll definitely buy the next future models of the XL’s franchise…

Look at the base port. Not enough base for me. I sent mine back. I’m in the minority.

Replacement charges are quite expensive.

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..

I ordered my L3 in November of 2021 and was hoping it would be delivered by Christmas that year for a annual Christmas party, but it didn't arrive. Understandably, that's when the shortages were happening so its not in Diamondboxxes control. It arrived in January 2022 and that day was a very special day. Opened the packaging and really couldn't believe how big it was! This thing is a tank! Powered it up for the first time, and played one of my most critically listened songs, and wow... The fidelity I heard over Bluetooth was amazing! Then I plugged it in wired and it got twice as loud I guess since the input signal is so much higher than Bluetooth, it can amplify it more. If you aren't careful about your volume on the UV meters, you can definitely blow it out though, had those woofers smelling a little having it only very partially clipping. Otherwise, if you use it at non-deafening levels or up to all the lights on, crystal clear, dynamic sound that, depending on the room size, it will shake the room. I also purchased a Sub 8.2 in December of 2022 to go with it, you'll have to see the review on there to get the full consensus. Obviously the XL2/3 will outperform, but sometimes I don't know how it would. Ceramic coated the whole box the aluminum, the duratex, all of it to protect it from UV damage. Anyway, this speaker is heavy, rugged, durable, and sounds absolutely amazing! Definitely recommend this if you really want a portable concert.
