Looking for new speakers for large audio room

Most of the speakers brands most of you recommended aren’t being sold by any local dealers in Thailand and. If they were bought online the price would be doubled or more for imported audio gear so I’m very limited most of them I have demoed most of the loud speakers 

local dealers sell their products the same price and usually have great discounts and no trade up program for most places even 

For example I had a vintage Bryston 4B amp and the dealer would not take trade up because it’s too old of a product.


and very small used market for audio gear.

I second the vandersteen Kentos. They have built in powered sub and I think your Pass is enough to drive them. It could be though that you have a twofold problem. Even with the high efficiency system you have, the room may just be too big. You might need more power.

How does the stereo sub line array differ from the DBA where you place them around the room? Does the line array work like the DBA in canceling out room modes? Thanks

Edit: my ceiling works as a baffle with wood going across if it’s affecting the bass.

cant Demo the vandersteen the dealer can only order them;)

Common clearthinker, why not!

Given you amplifier's power I think  Atma sphere's recommendation makes the most sense. Without a line source dipole I think horns will work best. However, with subwoofers your amp will drive Sound Labs 845's but you would need two more subwoofers for it to work really well.
I use JC 1's which are Class A to 25 watts and I rarely use more than that. I also believe your Pass will push a lot more power just not in class A.
