This thread reminds me... Whatever happened to ferrari?

Don't know; he hasn't had a post in a looooong time...

I have read some where that Carver ribbons radiate sound left and right but not top and bottom, to cut down on deflection from the floor and ceiling. If this is so, then laying it horizontal will destroy the sound field. The only good seat would be directly in front of it.

A driver's directivity into the vertical plain is called HASS effect. Carver ribbons have no HAAS effect reflections, this is good....most of the time. IIRC, Bob did some research concerning this phenomenom and the ribbon of the new Sunfire CRM series speakers have a different driver/or driver alignment in the center channel speaker.

Turning a 48" or 60"ribbon on it's side to use for a center channel would have it's advantages...say a really broad sweet and juicy like these nutz. spot. But even in my room that's one big center channel...and WTF would you put it? I would hate to sheild a 60in ribbon to sit on/around the TV...what would it weigh?

My personal opinion.................

Ribbons are great for (Stereo)
Don't use ribbons for surround !!!!!! WAY to directional, you need the rest of the room to blend sound.

Hate to say this... but BLOSE would even work better as sorrounds.

The ribbons are way too (pin point) in my opinion.

I would never use these for Mains... but they do sound really good as surrounds. If you can, (and I did) go audition them in a local store, and see what yuo think. Our Local BestBuy has some...
Here's what I prefer for surrounds... with a small surround sub as well.

Haven't seen one of these yet though...
VERY interesting center channel

This answer your question?

sweet and juicy like these nutz. looking set-up. Gota love it

All the good sounds are due to what IMHO is one of Mr. Carver's finest achievements, the M-500t. The AL-III's don't hurt either. Subbass that rumbles the entire room on explosions and the dum,dum----dum,dum---- dum dum of the Jaws soundtrack.

I see my babies are being well cared for.

Yes sir. I still get out to Portland once in awhile and don't want an a** whuppin from the proud original owner. Transferring Carver gear is kinda like putting one of your champion bloodline puppies up for adoption. You make dang sure they are going to a good home where they will be well treated. I know, they are just pieces of metal and wires, but to me each unit has it's own personality and I would never transfer one to an abuser.

I knew I made a good choice in you Skip.

A driver's directivity into the vertical plain is called HASS effect. Carver ribbons have no HAAS effect reflections, this is good....most of the time.

The Haas effect is a psychoacoustic principle relating to how humans perceive and localize sound events.

To localize an event, the computer between your ears pays attention to direct sound, early reflections and the reverberant field. Piecing these together tells you where the sound is coming from and how big the room is.

All Haas said is that if the direct and early reflections are within (IIRC) 15 to 30 milliseconds of each other your brain cannot distinguish between them as separate events.

In the LEDE (live end dead end) room treatment idea, early reflections from nearby walls where absorbed, and later reflections at and behind the listener were diffused. The idea was to separate the early reflections by at least 30 milliseconds AND group them together in arrival time (as nearly as if possible).

The end result being a direct sound, followed by a Haas 'kick' of early reflections (this time perceived as two separate events) followed by a reverberant field. The Haas 'kick' was supposed to trick the brain into hearing the original recording's acoustic space, instead of smearing the sound with reflections within the Haas limit. (ala Bose)

I might be picking nits, but the ribbon, being a dipole, will have a more figure 8 (front to back) dispersion pattern, and therefore less side wall reflections than a cone, which WILL lead to more accurate imaging in the sweet and juicy like these nutz. spot with little/no room treatment, but NEITHER type of transducer has Haas reflections. The reflections will either be within or exceed the Haas limit.

Enjoy!
