Apple has introduced a new full-size HomePod, two years after the original model was discontinued and not replaced. If you're looking to buy a new HomePod, there's one thing to keep in mind: To form a stereo pair, you'll need two identical HomePod models.
Let's say you already have a first-generation HomePod and want to buy a second-generation model. Unfortunately, but perhaps not surprisingly, you can't combine these two models into a stereo pair. Apple explained the:
Apple introduces second-generation HomePod
To create a HomePod stereo pair, you need two HomePod speakers of the same model, such as two HomePod mini, two HomePod (2nd generation), or two HomePod (1st generation).
This limitation makes sense despite the similarities between the first and second generation HomePod models. There are some key differences that will likely impact the ability to pair two different generations, such as the different number of tweeters, different chips inside, and software changes. This means that if you want to create a stereo pair with the second generation model, you'll need to buy two HomePods, even if you already own a first generation model. (Image: Apple)
