What would you do with this space? Horns?

[electricashman]

Ive started my built in entertainment center wall.
I made speaker openings 27in by 60in tall for the main channels and have plenty of room for a big center channel.

I had in mind an 18in folded bass horn, 12in mid bass horn with a horn tweeter. Biamped bass horn and Mid-high. Fill the whole 27X60 pannel and Id think it would have a nice sounding disperion along the wall with the amp rack and the lower cabinents installed.

center channel (home theater) would be a matching horn and two 12in mid horns. Im not sure how to get a good dispursion with the 3 drive horn center channel. I think I will desire the higher sensativity on the midbass for a center channel. I might just match it with the mains and do a single 12 and tweeter.

rear channels will not be horns Ill probibly go full range single drivers on those. a differnt project.

Id like to make horns work in this space. what do you think.

Where are you putting the bass horn?

For the 12 & the horn, you could consider a co-ax.

My idea was two bass horns, one to the right of the TV on the shelf 18in off the ground, the other on the far left side also 18in off the ground. the amp rack will be the space to the left of the TV.

I have not tried a coax,
The Eminence Beta-12CX 12" Coaxial Driver $80
http://www.partsexpress.com/pe/showd...number=290-504

It is rated at 96.7db sensativity
The tweeter would be higher then the mid by looking at the responce graph.

Horn loaded this might get up to about 100db sensativity.
The bass horn I had in mind is about 105db sensativity.

Biamped it might not be too noticeable.

The Coax should have a nice dispursion.

Two of those 12in coax could get me to 103db ish
could do a box like this

Is that what you had in mind for the coax?
What model's have you heard liked?

[planet10]

There are at least a couple threads that seriously examine the available co-axes. If you are going to horn load the 12s you do not have enuff space to do so, and even the dinky little bass horns you linked to won't come close to fitting into the available space. Note that it falls off precipitously below 50 Hz... a good 12" coax can go at least that low and you'd not have a need for an active XO -- realistically that horn probably is only good for an octave.

The Beta coax isn't very good. Combine it with decent full range horn mains and all it'll do is draw attention to itself.

Rog's plans are fine for PA, but I doubt I'd use them for high Q reproduction of sound, not when there are better alternatives.

Horns are by far the hardest type of system to get right. I speak from long experience. Go high efficiency direct radiator using Pro drivers.
Try this on for inspiration.

Generally I don't think horns are very suited for in-wall speakers as this would be. Horns are generally quite picky about their placement unless they are specifically developed to one type of placement, eg corner horns.
