Will this cause issues? Speaker placement.

Would putting my York this close to my ghorn cause any issues?

I would say thats not ideal. You cant flip them around or anything?

I can move them further from the York but then that closes my gap i have between the ghorns for my center tower to fit.

So its like ( [] york, [---] Ghorn)


[][---][][---][]

If i move the Ghorns back itll be


[] [---][---] []

That causes me no place for my center channel

I was thinking about building a hollow frame base for the yorks to sit up away from the port, figured thats probably my only real option if I want to utilize the center channel. If I use the center the ports will be blasting into a york no matter which way i put it due to the ports facing only left and right and due to room width

Could you post pics of the front wall setup? Might help visualize other options. Any way to get the port facing up toward the ceiling? Maybe experiment with it and see how the response changes. That layout might open some options for the LCR layout too.

Ports can't face up because the connector is on the back (bottom) . I can't face them forward cuz they would stick out to far in the room. I'll get a pic after work.

why not cut a side exit in the ghorns? block existing exit, cut out an equivalent sized hole on the side of the cabs. it will reduce the effective length of the horn. if memory serves, the ghorn is tuned to something like 17hz, so maybe effective tuning goes to 18 or 19hz. difference being you get the frontal area of the broad side of the cabinet, which is beneficial.

short firing into another cabinet though will present issues

I appreciate the idea but I'm not cutting up these boxes. I'd much rather build my York stands.

Well, if the connector is the only reason (and response is good with them turned up) you could place the ghorns on stands for clearance. You could also use a 90 degree speakon connector to keep the height as low as possible. Otherwise, switching to a terminal cup isn't the most invasive thing to do. That would eliminate the need for stands completely.

Also, I'm not very familiar with the York (Yorkville?) speakers you have and the picture of the driver arrangement is dark. If the HF driver is in the center (WTW), you'd probably benefit from raising them to bring the center of the speaker to ear level. So that might be better overall, especially if the ghorns are doing a good job energizing the room as they are.

My arrangement has horns firing into the front corners of a square room and gives great response at the MLP.

I also can't turn them up because my othorns have to sit on top of the ghorns. I think I'll do some rew testing and if that doesn't work out I'll build stands for the Yorkville u215s to get them up and away from the ghorns ports.

So i ran some measurements. I have never done this before so i have no idea if i even did it right. This is the combined chart. Orange is with the subs really close to the yorks. Clearly they suffer a bit around 12hz being close (at least that is what I think i am reading) so I guess the stands are in my future. If i am reading this wrong or even if i did it wrong please let me know.

Most likely, the roll off at 12hz won't be affected by building stands. Maybe the 15-30 hz -10db area. Easy way to see if stands will help is to take one measurement as is, then just pull the mains off the wall a few feet and remeasure without any other changes.

Are you measuring at the MLP with the mic vertical and the 90 degree cal file? (assuming a umik is being used)

Yes, pull the mains off the wall. Imaging will be improved as a side benefit.


EDIT: What's that sticking out of the wall in front of the left speaker? A gas line? Time to rethink the whole room layout.

Those are water lines. Essentially what I have now is best case scenario for layout. We just repainted and carpeted the whole basement so remodeling projects have stopped down there. I can't pull the mains out due to WAF, I can't swap sides due to a doorway behind the couch and to the sides.

On my graph there is 2 lines, one measurement of the subs close and one away from the Yorks. Both are near identical except the 12hz area when the subs are close. I just lose a few dB down low (3db)so it may be a small sacrifice.

In my eyes you're 10+db down from 30hz at 20hz, something already isn't right unless those horns dont go that low.

Did you post a picture of the entire setup? Screen and center? I can't open the picture of the yorks and g horns. It's like you just went too big for your space. The horn on the right side is just out in the open? Mid wall?

Can you draw a picture of the entire space?

What's this othorn sitting on top of g horn thing about?

ok youre talking about that dip in there, got ya. thats there regardless of placement with they yorks. the ghorns go own to 10hz i believe. the horn on the right is open to the stair case to the upstairs. the 2 tan boxes in the foreground are my othorns sub. those will be sitting on top of the ghorns.

Oh, so that measurement is just the yorks?

Is your plan a screen wall? Or what.

No that is just the ghorns. That is my screen wall but I have a roll up screen in the ceiling. It's a make-shift theater at best. My son had to move back in so I had to give him half my basement for his room instead of the custom theater like u had planned.
