My thought was to only use the new speakers for the turntable, keep the existing home theater for the TV. Those speakers have a matching sub available.Remember that sound doesn't come straight at you, but also reflects from all surfaces, so the front left needs to mirror the location of the front right or the imaging will be off - the same with doorways, windows etc.
The closer the speakers get to the corners of the room, the more sound will be reflected
If the turntable is connected to the speakers via RCA jacks, how will the TV be connected to the speakers? Are you planning on adding a sub? What are you going to do for the center channel?
that turntable is probably fine though, and the AT cartridge is a decent budget product.
Have you thought about Sonos?
I haven’t really looked at Sonos at all.
