Need speaker suggestion for a larger room!


OK, out there - here's my situation:  I'm a Hi-Fi guy that goes back to 1952 - Brooke, Meisner, Mc C-1, etc.
Stayed with the good stuff - Mc., H H Scott, Marantz up until transistors took over in the mid-60's. 
One thing an another, I drifted from serious audio in the mid-80's and watched improving TV (!).

At an advanced age (84), wife and I are crawling back: Got a refreshed C-34 and MC7250 for signal
and a pair of decent M/L Ascents for transduction. LOVE the mid-range spacial effect!  Bass, mid and low,
is disappointing. 
For your consideration: Room is 26'L x 20'W x 8'H (4100+ cu. ft.) and "live"( some carpet and upholstered furniture), but much reflective wall area (glass) on either side; No help on opposite wall.
Unfortunately, aesthetics play a role: Speaker cabinet must be cream, black, or silver (!). 
I'm a fan of Tannoy sound, if this helps (used to own a pair of 12' Silvers WAY back), but their cabs are all
Walnut, or similar. Also, don't need to go to 18 Hz - We're in a condo - so an HONEST 30 cps is perfect.
Music pref: Classical, 20's and pre- 60's jazz, Piano ensembles + vibes,  Blue Grass, Tannoy demo CD's (!)

I'm hopeful some of you up-to date folks will help us uncover a few good speakers options. Our budget:
no more than $7,000.00.  Oh - and good used examples are just fine. Probably preferred, given our budget!

Thanks a lot for whatever you can share!

There’s a black pair of Nola KOs at a deep discount. They’re an open baffle design so may exhibit a lot of the spatial characteristics you like about the MLs but with bass down to 30Hz. I think these would be a great choice for what you’re looking for.

Another great speaker that has excellent spatial characteristics is the Joseph Audio Profile. These can be found used for around $4000 or less used and I believe $7000 new. Here are some pix -- not very big but will fill your room with glorious sound, and I thought the black cabinets with silver drivers might work well with your decor needs.

One more I'll throw out as a long shot because they're hard to find in the US, the Boenicke W8 is small but images like crazy, and in its ash finish it kinda looks like cream.

Hope this helps, and best of luck.

Suggestion- go mate them up with quality build VAN DEN HUL speaker cables ...that’s what they are internally wired with.
I would test drive an all VDH cable array with matched interconnects as high on my wish list.
