a sinergy horn for domestic use

hi all

i think a floorstander sinergy horn with nice cabinetry for domestic use would be very nice. Here a rendering and design idea :

Cool.

Send the plans to Tom Danley.

Looks attractive. I like your thinking. It looks like you make the expansion tractrix though, whereas Danley I believe uses conical typically.

The vertical dispersion of around 90 degrees would make for floor and ceiling reflections, which is antithetical to the design.

The horizontal dispersion appears to be less than 45 degrees, which doesn’t look wide enough to cover the two chairs.

Looks cute, if you like looking at horns. I prefer grilles.

Doesn't a horn like that image flip? When setup in a vertical position like in the picture isn't the wider dispersion angle in the horizontal plane?

In the narrow direction of the horn there is beaming at high frequencies and quite wide dispersion ar low frequencies. In the wide direction of the horn dispersion is more controlled across the operating frequency range.

Eva! You got that one exactly right.

Those speakers should be turned on their side to work at all correctly, but there isn't really enough of a horn there to do much control anyways. Horns can't be that wide and work properly and they need to be longer and narrower to get any directional control. Looks nice, sure, but looks arn't everything and in loudspeakers good looks tend to be contrary to good sound.

hi Earl, Eva

thanks for your opinion. I have done two things in the following design :

incorporated a reduced size Danley tapped horn DTS20 sub, in the back part of the cabinet, to cover below 50hz. It would be driven active with a 8" woofer. Increased the length front horn ( 24" ) , to get better directional control. Horizontally, it would have 45 degree aperture, and vertically 80 degree. Certainly , if i would do the oposit ( 80 degree vertical, 45 degree horizontal ), would be better, like used for radial horns, but one main goal is to make a floor stander , not larger than it is now, around 25".

Wow, acoustics aside, looks awesome. What kind of software are you using?

Rendered objects dropped into Photoshop CS2 would be my guess.

Whatever it is - nice work!

BTW, Bear always used to say tuen the horns vertical, at least for small rooms.
