re: Sonos system for 5 bedroom house

I agree it'll outpace your setup in cost, but I don't think what you're pricing is what most people are doing/would need/would want.

The people I know with a Sonos setup, including myself, have PLAY speakers and a soundbar. I don't know anyone who has the sub. I certainly don't know anyone who has multiple playbars and multiple subs.

A more realistic whole home setup for most people, I think, would involve a soundbar, sub and 2 PLAY 1 speakers for home theater and living room audio. Then a series of either Play 3s and 5s for remaining rooms. Such a setup would please anyone but audiophiles, and would be plenty for all but the most massive and cavernous homes.

I'm sure that would still come in more than your setup, but a Play 3 will provide excellent sound for a bedroom at about 260 dollars. A Play 5 can truly fill up a large living area for 400 bucks, as would a playbar. So on that type of setup, which is the prototypical setup, you're going to shave a few grand off of your estimates.

Moreover, depending on where your audio is coming from, you probably won't need a Sonos Connect or bridge at all.

Anyway, for the 5BR setup I would anticipate it'd look more like 2500-3000 for the Sonos setup. So sure, still doubling yours, but not as massive of a difference.
