When I started to put my system together a few years ago I ended up with the Tune Tots because I felt that their highs were better than the other bookshelf speakers that I was able to audition. The others that I listened to, were B & W 805D, Vandersteen 2ce sig, Focal and Spendor. I no longer remember the models of the last two. Mine are paired with a sub system. They do cycle quite low for their size but IMO the 5.5" woofer is too small to cycle that low with any real authority so I have mine crossed over well above 80Hz to prevent any woofer damage during louder listening sessions.
I have not heard the Heritage so I cannot compare them.
