Does anyone here know anything about these speakers. Enclosure design looks very interesting on paper, but I was curious if someone heard these. They only have two models it seems.

Nobody heard about these things?

Cadence/NorthCountry Audio Home Page dealer is in New York, maybe a weekend in the country?

[faust3d]

NorthCountry Audio has them on sale as well. If I am ever around I might stop by, but without a car it's a bit difficult

Finaly I speand some time with these, since my uncle was curious enought to track and pair donw and buy it.

 

 

Very unusual speakers that combine the best and worst things about crossoverless design.

[bjarnetv]

did it come with the "Bass conture module"? 

seems a bit counter intuitive to try and make a "pure" speaker only to use EQ and mess up the dispersion by using two fullrange drivers.

 

also, are the drivers "front slot loaded" or are the 6,25" drivers just that narrow?

so difficult to judge scale from photos

Yep, it came with bass conture modules, basically shapes the FR and inserted between the control amplifier and power amplifier. It made them sound better tonally and bass was better controlled with BCM. The opening is smaller than the drivers so it's kinda like a strange waveguide in there and a complex labyrinth inside. Speakers themself are made from some kind of composite stone "Gibraltar", cold to touch and heavy as heck. These things are big:

Height 39.5 inches (100.5 cm)

Width 10.75 inches (27.5 cm)

Depth 17.5 inches (44.5 cm)

Weight 115 lbs. (53 kg)

Yeah, but I bet they're inert, too.

slot loading increases bass, attenuates treble and widens the dispersion by increasing diffraction.

all good things when playing fullrange speakers without any crossovers... if done right.

 

are they closed or vented? BLH maybe?

No clear indication on what is inside but I would bet it's some kind of labyrinth, not BLH, but more of a transmission line type of a deal since they have that type of bass response, since there is an opening on the bottom.

They better be with all that artificial stone stuff.
