Well. It was in place for many years until the restaurant closed.

If you want to maximize the floor space and ensure good imaging, then mount the horns close to the ceiling (assuming flat ceiling, and higher ceilings could be better up to 5-6 metres). This avoids the issues with corner horns that you see in "The Loft" K-horns below--which required the added extensions of the Khorn top hats from the bass bins...

Keeping the audience out of the direct sound path and outside of 2 metres just about the speakers radially will ensure a stable imaging sound field. Doubling the number of woofers from two to four 15" diameter versions (using mid Qts drivers) will provide you the capability to elevate them, and eliminate the immediate need for subwoofers as shown in the orange SH-96/DBH-218 stack picture further above. If you want to have "touch and feel loudspeakers" with subwoofers, then you could do that if you place them in the room corners on the floor. Only a small amount of absorption next to the horn mouths on the side and front walls (~60 cm squares) should handle any midrange early reflections to assure good imaging.

I note spiritland are near Kings Cross. That is the new trendy area. So much so that my employer has just moved their head office as was getting too expensive and the city of London proper was cheaper! I fear location will be far harder to sort than the sound system.

That's usually the case with hi-fi venues--everyone's lease seems to always be ending and the owner looking for the next place to set his tent poles. Dave Mancuso apparently lost his lease more than once in NYC and actually went on hiatus with The Loft when new locations didn't work out.

The significant thing about Mancuso was apparently his continued emphasis on hi-fi sound and simplified signal path--no "special effects", queuing systems, beat matching, etc. In other words, no DJ or club stuff. He was reportedly a stickler for better playback devices: turntables, cartridges, clean and simple electronics, etc. It's an enduring formula that's survived to today.

In my opinion, you need Sweet speakers, nothing to bright.

As the provided videos show Jazz Coffee Shops are big in Japan. And they take their music seriously.

Given what I know of the UK (which admittedly is very little) what you consider a large room, the USA would consider a modest medium room. So, some sense of the actual room size is critical to the equipment.

Then we come to BUDGET? In Japan, they spend MANY thousands on the equipment and thousands more on content.

Then who is going to control the music, and I'm think along the line of a DJ here just to illustrate what I mean. People making and serving coffee and food, probably aren't in a position to keep fiddling with the Music. Then, how do you prevent the marginally employed teenagers working them from putting on DEATH METAL? Though there is certainly room for a range of music.

One option is to Network Stream using services like Spotify and Pandora. You can create long Playlists, or, unless I am mistaken, you can pick a genre (jazz, blues, ...) and it will stream a random selection of music from that genre. That is a way to keep the music flowing without the need for much monitoring.

Also, the selection of music on such streaming services is HUGE. Likely if anyone has a request, you can bring it up on Spotify and play it.

Also note that while Spotify and Pandora ... sound pretty good, there are CD quality streaming services like TIDAL, DEEZER, and similar. The bandwidth is higher, but still well within commonly available bandwidths.

Though NOTE, you do have to contact the Govt in the UK, or where ever, and get a license to publicly play music. I can't remember what the name of the organization in the UK is, though I've seen it a hundred times, but that is something you have to look into.

If you have the music on one end of the room, as shown in the videos provided by others, then those interested in music can sit closer, and those interested in conversation can sit farther away.

I would recommend somewhat large speaker playing with ease, rather than small speaker playing strained.

Fortunately, assuming the shop will be in the UK, the UK is a great place to by audio equipment, even despite the insanely high Value Added Tax. Good selection, good prices.

To make this a desirable place though, the audio equipment and speakers have to be WELL ABOVE average. No one want to go to a place and listen to a cheap stereo screaming away. It must have some finesse.

Just a few thoughts that occurred to me at the moment.

While we are at it, here is another Jazz Cafe in Japan using JBL Paragon speakers recently modified by Kenrick Sound in Japan. -

Don't get me wrong; I really like the front horn loaded coaxial idea.
I would probably make it 4 way though; I do not like the idea of elaborate box design to distract every bit of bass out of a 2 way speaker.

Not into butch/steampunk
Like minimalist & utilitarian

those are excellent recommendations
synergy horns would be great for dispersion and headroom
i would probably add some remedy for sharp edges

adding a center channel is also a great idea, given there is enough space of course

Good point

But I am actually trying to address that problem with providing something different.

So hopefully, enthusiasts would travel the extra mile to come and hang out in a music cafe that is in an area with cheaper rents. An old factory, warehouse conversion, railway arch etc...

Mr Sakuma's tiny cafe in Japan has a single Altec VOT as its main speaker YouTube
