@jkp posted a QVC deal that beats the above when buying the sub separately.
To add to that, for first time buyers, you receive a $10 off Promo code so that brings the price down to $90 for 2 Echos. Add the sub for $130 and that total is $220.
Now if the Sub goes on sale…then you will have even more savings!
I recently purchased the 2 Echo Plus+Sub for $330 and I do not believe it’s worth it after sound testing.
