Just my 2cents, but speakers are speakers are speakers. I'm no brand snob, but all credit to those who can pick the sound difference between cheap and fancy. I've had a few setups from very expensive to very cheap gumtree jobs. I've also had Accusounds, which were pretty decent, albeit $2.5k for the 5 mains I had. I'm currently using bookshelf sized Tannoy and Krix speakers that I scored cheaply ($200) on gumtree. I run a 12" subwoofer with a modest 150watts. The whole system does the job for movies, but lacks a little bit for stereo music compared to a tower setup with bigger mid-bass woofers like I've had in the past. The little Bose Accoustimass setups really only work for surround sound, as they rely so heavily on the bass module. The bigger the woofers you can go on your main front speakers, the better.
I reckon your money is better spent on a more modern amp. I got a Denon a little while back for $500 or so and it handles HDMI in and out and has bluetooth, 4K, multi-zone etc. It's nowhere near as heavy as more serious amps I've owned, but it's doing the job.
10 years ago and I was lucky enough to build a new house with a dedicated home theatre and I also installed in-wall and in-ceiling speakers in the living area. Honestly, the in-walls and in-ceilings did a brilliant job. They had 6.5" mid-bass drivers across the front and they had plenty of punch. I didn't bother with a subwoofer on the lounge room setup, as it didn't need it. My wife loved that they were very unobtrusive and my then toddlers couldn't climb on them and knock them over.
