Wow MiWi!!!

I didn't realize how darn big those horns were! DIY huh? I'm thoroughly impressed. I have a great audio ear, but not even a smidget of DIY capability when it comes to building amps, preamps, or horns such as yours. I wished I lived near you as I'd love to hear a system such as yours!

Congratulations on building such a wonderful looking (and I'm sure wonderful sounding as well) audio system and speakers! You're a very talented person.

Thank you.

Yes, I already thought about some subbasshorns instead of the tapped horns.
(I already did the simulations and made the CAD drawings)
My wife has not been amused.
Im quite pleased with the tappedhorns, so this is not an urgent project.

The speakers indeed look quite small with the pictures of the whole room.
I guess this is because the ceiling is quite high. (sloping from 8ft to 17ft high)
The midbasshorns are nearly 4ft wide, 3ft high and more than 4ft deep.
The midhorns are 28" wide and 22"high (hornmouth).

Their size is one reason why I hesitate with the subbasshorns

I really love the look of spiral horns (like John built them for example).
And they would fit really nice under the sloping ceiling, making for a giant hornmouth-extention.

But Im not sure if the looks will be to much with 2 spiralhorns.
The midbass/midhorns are quite prominent with their kind of "space-age" look and their size.
As the tappedhorns hide quite well and are nearly invisble, the focus is on the main speakers, which keeps a good balance I think.

Right tappedhorn, hidden in the other room and just "firing" into the living-room.

Left tappedhorn, pretending to be some kind of bench.

What are the other dimensions of the room... i ask because my ceiling goes from 7->17'. The sloped ceiling really helps room sonics.

Living room and kitchen-area are one space (can be seen on the last picture on the right side).

The whole room is about 32ft wide (about 22 where the speakers are) and 26ft deep.
All the walls are drywall (1" wood + 1/2" gypsum cardboard), which means the whole room is a panel bass absorber.
I got really little problems with bass-peaks, the reverberation time underneath 300Hz is really good. The hole for the stairs also helps with this.
I designed the house (and built most part of it).
First of all it is a livingroom and I wanted it to look good / feel good. I just tried to get a good compromise for the music as well and aimed for a roomgeometry which will give little problems with bass.

Mid high reverberation could be improved.
But it is by not as bad as most people would think from the pictures. The speakers are beaming strong and the walls are quite far away.
There are acustic absorber hidden behind the pictures, but Im planning to get more.
I placed an order for two big new pictures printed on acustic-cloth (each 4ft x 6ft), which I will wrap around 4" thick absorbers. They will be placed on the right side where the white picture is now.
The curtain on the window on the left will be replaced with slideable acoustic panels. (4 panels 2ft x 5ft)
(symmetry left/right is important, tested some different arrangements to find out about the influence)

The speakers are are not aligned parallel to the back wall intentionally. They are angled to get nearly the same delay for the first reflections on the listening spot.

Actually, Dave's room sounds very nice and I've spent many hours (over a number of years) listening to different speakers and gear.

Best Regards,
