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!

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.
@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. 
Zero bass traps in my room. Tried em many years ago. Well a lot of people rave about them. Make it sound like you just can't live without em. Well I tried and tried. Of course they made a difference. Just not an improvement. Thankfully never cost me a cent!  

This stuff is not that hard. Its just there's a lot of it. A lot of simple stuff. But its just not that complicated. So just keep learning all the little bits. It all adds up. Especially if you learn the bits that actually work. ;)

ronboco, I use WiFi and can see two possible problems.  One is interference.  There is a dozen of channels at 2.4GHz, but you can only have three non-overlapping and I had dropouts.  I switched to 5GHz and it is fine now.  The other problem is delay.  Music is transferred in packets and plays with a couple of seconds delay.  When playback stops it keeps playing for couple of second from the receiver's buffer.  It makes no difference, as long as all music is delayed.  If it is only for subs it has to be time aligned.
I’m really looking forward to hearing it with music and movies. Did you find you still needed bass traps with 4 subs? Our room has 18 ft ceiling and is open on two sides. I found it interesting that GIK recommended at least 24 bass traps as well as some diffusion and mid to high absorption and Vicoustics recommended 0 bass traps with only mid and high absorption and no diffusion. I think I’ll wait on room treatment until I see how it sounds. Thank you again. I have learned a lot reading yours and others posts since I joined although a lot of it is still over my head. 
Main idea with multiple subs is to create lots of different bass modes in different locations. Easiest way to do this is put them all around the room asymmetrically. In other words along the walls but each one a different distance from the corner. 

But really, they're not fussy at all. With one sub, that one sub has to be very powerful and put out enough bass, and so the modes it creates are very powerful and the bass is lumpy. You move and listen, move and listen, trying to find the least lumpy spot. 

With four subs they all add together so each one has to put out much less bass so the lumps it makes are much less noticeable. They're there, but small. So technically you could go to all the same trouble searching around for the perfect spot for each sub. That's the crawl method- put one in the sweet spot, crawl around listening for the best bass, put one sub there. Repeat for each sub.  

I tried doing this. The result was no different than when I put them where they were asymmetrical and worked better with the room. Tim did this, wound up with them almost exactly like I said, near to but different distances from the corners. 

Actually if you read my review it raves about how great they sounded when all I did was plop em down no real thought or planning other than near a wall and near a corner- but not equally near. Its one of those rare things in audio where its just super easy to get outstanding results. As long as you have four. 
@millercarbon. Thanks for your input. With subs being Omni directional will placement still be important ? 
Subs work fine with ordinary hookup wire. Subs aren't super responsive to wire quality the way full range speakers are.  So I would think they would work fine with wireless. For sure the benefit of adding those subs is greater than the difference in how they are connected. If that's what's holding you up relax, and go for it.
