We are planning (hoping) to remodel our place to create a large open listening space that opens to kitechen, etc. similar in size to OP and others here. We put together two systems with this future use in mind. Two thoughts: 1) definitely explore Tannoy, but I suggest go big if the budget permits. I have the Arden's (with Tannoy super tweeters, driven by Luxman M-900u monos), and they are very good, but to us, not good enough to drive such a large space. For that, we went with Tannoy Kingdom Royal Carbon Specials. 2) We have concluded that no 2-channel system is complete without a pair of top quality subs, and for that I mean REL Carbon Special or above (Nos. 31/32). Yes, the RELs bring more to the entire spectrum, even with the big, full-range Kingdom Royal. BTW, with the Arden I am running a pair of REL 212/SX. Big room, big drivers.
Speakers for a Large Room (20’x37’)
Open concept listening space with speakers on one short wall and kitchen at the other end. Furniture about fifteen feet from speakers. I assume I'll need large speakers and am considering Klipsch Cornwalls as well as Tannoy Ardens, but open to suggestions. I also assume standmounts are too small for the space. I should mention I mostly listen at low to moderate sound levels, occasionally cranking it if the wife is out. Thanks for any input.
