Amazing Line Source - A new speaker design by Bob Carver and James Sauter
treitz3 wrote:The imaging characteristics Bob had talked about in the videos was a pleasant and very unexpected surprise in a room that was completely unfit for his vision. They were also brand spankin' new with zero hours of burn in with anything associated with all of the parts that went into the set we heard. Also, the tube crossover that is planned for these speakers was not present at the time of the audition and Bob hasn't even had the first set he and Leslie voiced brought to Washington for voicing in proper surroundings. The potential for these speakers is off the charts but it is of my observations that the timeline for audition was pushed to the limit and it is too soon for an observation worthy of said speakers.
Basically, what I am saying is that the speakers were missing key components. They were in the worst acoustical environment possible. The crossover tweaking has not been properly done yet and the tubed crossover is still a vision at this point, not a reality we actually heard while we were there.
They were designed for an 8' ceiling for no floor or ceiling reflections that create distortion [refer to video]. The ceiling at CF was at least 30 to 35' tall with a loft about 12 feet out at a height of 12-14'. Wood floors, wood walls, glass directly behind them and stone to the right of them. They were never really "set up" with the Sumiko setup, Cardas setup or any other set up for optimum sound due to time constraints with the tube amp build that took up most of CF to begin with.
It is of my opinion that any observation should be taken with an extreme grain of salt, considering these factors. It's like testing a Corvette's handling ability on a track that has oil on it, rain and everything that can be stacked against it concerning handling......and then having the privy few offer their evaluation of said Corvette's handling abilities.
I am looking forward to hearing the completed product and next year Carverfest will be all about the music.

That's a good thing because with like 7 million of them in a line array, it's probably possible to eq them to sound like just about anything you want. The midwoofers achieved the intended effect; like Ohms, they just disappear into the room. It would be interesting to see the T/S parameters on them. One has to wonder if the extrusions will be sealed, or open, and what the impact is of so many speakers in such close proximity. The problem with listening to them was that James always has some kind of JL product on hand, so all ya' want to do is play bass tracks. My apologies to the teenagers. It was inappropriate to play Bassgasm at 3AM. Glad the roof survived.
Kudos to the Sauters for bringing these things together in basically no time at all with finished product quality in what is essentially a prototype. The fit and finish, second to none. The bases are absolutely perfect, with feet hewn from solid metal stock. You can probably climb these things if you want. They look very sturdy. We've all seen the assembly process and these solve the problem of wide speakers taking up massive amounts of space. Heck, with covers on the front, they can almost be disguised as structural supports.
All that said, if I owned a pair, I'd triamp them: one channel to the ribbons, one channel to the left midwoofer line, one channel to the right midwoofer line (per speaker). I'd time-align the whole shebang based on where I put them in the room and knock the gain WAY back on the ribbons. I mean there's enough ribbon there to rupture your skull. Seriously. Rupture it. Bang. It's gone.
Ultimately, I have no idea what these speakers will sound like. None of us can, really. One thing's for sure. These things are going to be VERY dependent on room placement. It'll be interesting to see how that is addressed in the end product. I'm sure the Bobs can make something that sounds heavenly with all the quality materials and exceptional craftsmen involved with this product.

kingman wrote:Don and I agreed that the sound stage was huge but above the usual listening height giving the impression you were in the first few rows of a concert looking up. They sound very nice as would be expected of anything that Bob would endorse or James would build. It will be interesting and exciting to hear them as they evolve from the prototype stage to the final version.

You're probably right, I bet they do as poorly as all his other speaker designs.
