Have 300b MB want a killer pair of Hi-Eff speakers


Looking to fill a 12'X25' room with a speaker that will do justice down to 38hz. Speakers must work 5+ feet from the back wall. May try to integrate a sub down the road,stand or floor mounted ok. 50's & 60's Jazz and vocals my pref. Gota be able to do the left handed piano keys and acoustic bass. Thank you in advance for your recomends!

You could buy a pair of Omega's Hoyt-Bedford Type 1's for $795./pair, which are terrific speakers at an incredibly low price and then buy two Hoyt-Bedford Type 3's which are subwoofers at $700 each and can double as stands for the Hoyt Bedford Type 1's. The Type 1's are 97dB and you will have one hell of a speaker system which is very tough to beat for the price. As a bonus the Hoyt-Bedfords are beautifully finished.
Prcinka's recommendation. There is a pair on Musical Affairs Grand Crescendos for sale here now at a nice price. (Korea) I did have the "pleasure" of listening to a pair recently, although paired with a Leben CS 600 which was much more power than they needed, to be sure, tho very excellent! I use 300b/45 set amps, so I chose the Beauhorn Virtuoso with Lowther DX4 rated @ 105. Some complain of their lack of extreme frequency representation at both ends. I am very happy. With my most quiet music AND if had been recorded at low volume , I have tried my 45's to almost top volume in my small apartment. For you? 300b+MAGC=:)

I Suggest a pair of Avantgarde Trios with a stack of bass cabinets. That will only put you back about $150,000.. but you did say you wanted "killer."

I don't know if this still holds true, but back in March Renmeister said he had
"an $8k budget for speakers give or take a thousand"
. But, he has an interesting criterion in that
...speaker that will do justice down to 38hz (AND) must work 5+ feet from the back wall.
I think, true 38Bhz performance, not -6dB or more down, without wall/boundary enhancement is pretty hard to do without lots of power(or really high efficiency), self-powered woofers, or fairly large horn-loading cabinets.

In case others are wondering, it seems Ren's latest reference point is Avantgarde Uno's which have a self-powered (250watt) dual 10", long throw, subwoofer cabinet in each speaker that covers 18 - 350 Hz.

Bass wise, that's a tough act to follow with 300B powered speakers placed 5+ feet away from the nearest wall.
Yet another recommendation for a PHY based speaker. If you want true bass down to 38, you probably want to use a speaker with a 12" PHY. The Tonian Classic 12 fits the bill. There are other very good PHY based brands but I've always been drawn to Tony's speakers and the way he integrates the PHY driver with his modified supertweeter. PHY speakers are not cheap but I find they are worth the additional cost.
