Wireless or wired?


Top of the morning everyone! I will be adding a 3rd and 4th sub to my system and am considering going wireless for ease of placement. Will sound quality be the same as wired? Thank you!

@kijanki Thanks for the advice. I will be using RELs airship wireless system. I think it is 5.8 GHz. I will check to see if the delay is accounted for. 
For reliability issues, I try to go wired any time I can, and relegate wirless to convenience devices, but not music or movie streaming.  Of course, I'm in a dense apartment building with 2 dozen wifi signals.
