I moved now Kef sound bad

Hi I'm somewhat new to hifi.

I've moved and it seem that my listening room is now too big. Previously my speakers Kef XQ-5 sound great with good imaging and bass presence. My listening room was 11x14x8, now it is 21x 19 with 17 seeling. I'm using a Nad 90 watt receiver. I guess that I'm not feeding the speakers enought power!

A ny body ahad the same problem. How can I fixe it,??

thanks

David

It looks like your room dimensions are not near the "golden ratio" for best Hz responce. The width and height are almost the same , which is bad news.

What is the db SPL of your Kefs? I doubt a more powerfull amp will solve anything. (Remember, if you double the power, you only get 3 more db)

Assuming you like your speakers, then for a large room consider a subwoofer - a JL F113 should do the trick.

A complete analysis of the room's acoustic properties would be the place to start. Check the 38% rule. Do acoustic measurements of the room to find where the nodes and standing waves are. Try pink noise measurements. Using the measurements, start moving the speakers around.

I forgot to mention that I leave in a condo so the room mesurement included th kitchen, and dining. The left speaker is 30 inch from the wall, the right is 36 from the counter they are 8 fee appart and 12 inch from the back wall. My listening position is 8 feet in front.

Can you tell me what is the 38% rule?

I don't the SPL of my speakers , how do I check?
