Agreed, i looked up Stereolab and all i found was a band. I would love more info, they look beautiful, good horns tend to lok right and hat is a corker. I am a fan of tractrix my lower mid horns are based on the tractrix curve.
Do they have a website? |

Lovely horns, fairly pricey but I bet the quality is good. Bet they could be great for HiFi customs if you had a nice 1"/1.4" driver sitting around

Did you finish your work on these, I am wanting to build a bigger 12V rig over the next year and these may do the trick?

Wow Corian, nice inert material and impressive thermoforming. 10mm that is interesting it's only available in 9 or 12 which likely means that 2mm is stretched out in the thermoforming process. No easy task. Problem with it is its brittle, a good impact and it shatters, it also scratches very easily. Not sure how well it would fair in a touring application. Need to be boxed for certain.

Unfortunately, whilst on axis sound was superb, these, and all other tractrix flares i have played with ( 18 sound and a couple of unbranded ones i picked up somewhere) suffered from too much HF beaming, giving an inconsistent sound and making splaying multiple boxes impossible.
With flares, you cant beat the physics unfortunately - and i had to compromise and use large CD flares that whilst ultimately sounded poorer on axis were array-able and far more consistent across their coverage area giving a solution which was workable. For me, tractrix flares have one use - hifi where you have one focused listening position and need very high sensitivity through the use of very low powered valve amps, and thats about it.

Chris did you try the 4594Nd on the 18sound XT? With FIR filtering applied to correct some of the dispersion anomalies it's damn good - but as you say it's not ideal for more than two per side
Nor is it cheap! Edited by toastyghost - 06 March 2017 at 10:35am |

Well there must be an issue with that sim because they provide their own isobars, polars, DI and so on here:

Really difficult to compare as the scales (dB and frequency) are so different?
