What are best hi efficiency speakers under $1000?


I'm moving soon and will need to change my setup a bit. I'm using a Luminescence preamp with a vintage Luxman tube amp. I listen to a lot of records and I love the sound of this system. For about 17 years, I've listened to this system with a pair of 46 year old Bozak "Urban" speakers. They've got a great big sound, but they are big physically too (24" x 24" x 20"). I need to get a bit smaller, at least in width. I need to find something that is efficient due to my rig, and can still deliver a big sound (10" or 12" woofer would be good here). I'm okay with buying used also - preferrably under $1,000. I've considered Klipsch Heresys, but I've never heard these. Any suggestions on decent speakers that conform to this profile? thanks for any help in this regard...

bottom line is all speakers sound great with tube amps so you can't go wrong,just your prefereance so try to audition first if you can,Nick

how many wpc is the luxman? how loud do you listen and what do you listen to? how big is your space? hi eff. means a lotta different things depending on who you ask. Tvad is right, many speakers sound like crap with tubes so... unless of course you have a $20K world class model. i owned a luxman ss back in the day and am glad to hear that you still use that classic!

Heresy IIIs are amazingly good speakers, although slightly off your budget...mine are the Capitol Edition (no biggie, just list for 500 bucks more) that cost 1500 bucks new from Ebay. Here's a cool review: https://www.stereophile.com/content/listening-119-ken-micallef-june-2018
