JJkizak Posted January 1, 2021 Share Posted January 1, 2021 If I add side walls to my 1965 K-horns like the new A6 will that perform the same as the A6 on the lower end if I pull it away some from the walls? JJK Quote Link to comment Share on other sites More sharing options...
mikebse2a3 Posted January 1, 2021 Share Posted January 1, 2021 I would expect it to allow you to space a small distance from the corner with the ability to rotate/aim the on-axis response toward the listener in setups/rooms that would benefit from that freedom like the AK6 version provides but the frequency response of the system will be affected by the side panel additions also which the AK6 crossover addresses and you might find the need/ability to compensate for the enclosed back performance changes to your 1965 model likewise. miketn 1 Quote Link to comment Share on other sites More sharing options...
kevinmi Posted January 2, 2021 Share Posted January 2, 2021 I enclosed my backs about ten years ago. It gives me the freedom of not having to worry about sealing the cabinets in the corners. Bass always sounds good, even when toed in or out. Quote Link to comment Share on other sites More sharing options...
LarryC Posted January 2, 2021 Share Posted January 2, 2021 I wonder if they'll sound exactly the same if they weren't designed for it from scratch? Wasn't the AK-5 network a modification for enclosed backs? Like Mikebse2a3 says... Quote Link to comment Share on other sites More sharing options...
Bosco-d-gama Posted January 2, 2021 Share Posted January 2, 2021 Lemme ask this. What difference does it make whether it is backed to a wall or wood? Mine are cornered in traditional fashion. Yet ‘all’ the bass does not get reflected. I can hear bass thumping through the adjoining walls. If bass reflection is the goal why not back them with something heavier like rock or a very dense and thick piece of wood? Has anyone assessed bass reflection from the materials perspective? In other words if I had my corners covered in sheet slate where the khorns set would that provide any benefit? Quote Link to comment Share on other sites More sharing options...

I think you are confusing several concepts: reflection, horn loading, impedance transformation etc. All the wall, or wood back, needs to do is provide a reasonably rigid boundary so the column of air has higher overall pressure at the throat end and lower at the mouth end (IOW, the column's cross-sectional area needs to expand as it gets further from the throat). Don't bother with fancy materials. Quote Link to comment Share on other sites More sharing options...
JJkizak Posted January 3, 2021 Author Share Posted January 3, 2021 RandyH000 provided a link to a wonderfull video of adding sides to the K-horn in the other thread I started in the technical section. JJK Quote Link to comment Share on other sites More sharing options...

Don't bother with fancy materials. Well I am thinking bass absorption versus reflection....... the audible component. We know that sound can be dampened by material alone so I’d presume less absorption would translate into more reflection? Would this result in a ‘tighter’ bass response? Isn’t this a similar (if opposite) treatment consideration to dampening a room with bass traps? Quote Link to comment Share on other sites More sharing options...
