Welcome to the SMD forum!
I posted earlier about my poor bluetooth with my L2. I recently sent it back to Diamondboxx for "warranty" repair and they quickly replaced the antenna to an upgraded version. Great customer service!!! I hope they can fix the BT range issue....because the Diamondboxx is the best sounding bluetooth speaker I have listened to. I'll post here if the range issue is fixed. At around $900...the only competition is the (new) Soundboxx. It does play louder than the L2, has much better bluetooth range......but is not up to the SQ of my L2. I am seriously wanting to purchase the XL2.....but need to confirm the bluetooth performance.
