And, with Amazon looking to push Alexa+, it's certainly time for some new models.To that end, the $100 Echo Dot Max and $220 Echo Studio are up for pre-order and will ship on October 29.

Even so, it has a powerful high-excursion woofer that delivers deep, immersive bass and three optimally placed full-range drivers to create immersive," room-filling sound, according to the company.
