I bought my house and the previous owner had ceiling speakers mounted. There are 4 circle cutouts. I'm not sure what size speaker he had but the cut out space is 8-8.5 inch. Looks like he ran a 5.1. I am planning to fil the holes in as I am tired at looking at them. Wanted to know what are some good speakers to put ceiling wise. I would need 4. Looking to spend no more than $1000. Also do you guys know if a speaker has a smaller cut out space size if it will still work or fit? I am looking at buying either a pioneer receiver or Yamaha. Please let me know what you guys would recommend. Thanks. Any tips or advice on speaker or home theatre would be much appreciated.
