    This XL2 speaker is so good that right after I bought my first one, I purchased another. I also purchased the sub8.2 to go along with the XL2. Best speakers ever!! Don't hesitate! These speakers are not just another
    purchase but an actual investment. I truly believe I could resell my setup
    for more than what I bought it for!

    Seems to be a great product so far. Diamond box never disappoints.

    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.

    Do not buy until they guarantee shipment

    It's been 3 months since I've ordered this sub and customer service keeps giving me the run around. "Oh the chips are not here, supply chain, blah blah blah" yet they keep offering sales on a sub that they can not deliver. Be very careful with your purchase. Until I get what I paid for, I no longer consider this company trustworthy.

    As far as I know, this is a total scam. They tried to placate me with a "free" mini speaker, which I appreciate, however that doesn't come close to compensating me for the money and time that I've wasted on this company.
