Question: what is the difference between amazon echo plus and the 2nd generation?
Answer: The first-generation Plus has a 2.5-inch subwoofer and a 0.8-inch tweeter. ... The second-generation Echo Plus has increased back volume and a larger subwoofer at 3 inches. It still has a 0.8-inch tweeter like its predecessor. This means better sound quality (stronger bass, plus crisper mid- and high-tones).
