Eighteen Sound ND1460A compression driver & 8M400 8” midrange
For those seeking some decent compression drivers that don`t cost fortune, I can suggest to try the Eighteen Sound ND1460A compression driver. It has aluminum dome and polyester suspension and 1,4 inch exit throat. Does it sound like S2 ? Probably not, but I have tried lots of B&C (ND950 was especially nontransparent, others were harsh), RCF, Beyma and P-Audio, all typicall PA drivers, but seems to me of all those only ND 1460 A was suitable for home systems. I am using it in a 60 cm round tractrix horn along with Eighteen Sound 8M400 8" midrange (also excellent) in a 95 cm round tractrix horn (unfortunately without compression chamber), crossover cca 800 Hz. I used to have a B&C DE 32 bullet tweeter in between (above 8 khz) but stopped using it since 1,4 incher sounds better even in the highrange. Intend to use another 30 cm horn with the second set of ND1460A, new crossover points: 800, 3000 and later (hopefully) 12000 Hz with a Lazy ribbon tweeter. ND2060A is actually the same driver, but with 2" adapter. Those used to vintage gear might find it laughable, but recommended to all the others.

Cheers!

I had a dream...

Well, do not be under impression that vintage drivers are an assurance of some kind of quality. They are not; in fact in most of the case the opposite is true. I always proclaim – it is only God knows why the horn-loaded drivers suddenly sound in the way they sometimes do…

I never used this Eighteen Sound driver but in my past I had a “dream” about a perfect driver. It was not the real dream but rather a notion that I can go somewhere, at some kind eBay or junkyard; buy some kind of ugly and unknown driver that suddenly would throw the “perfect sound”. Since then I realized that this sweat hallucination although not improbable but not necessary helpful. I still feel that any contemporary driver might be perfectly fine or might be not – it is not upon the driver only but also upon the system designer’s intentions and references. The desire of the system designer to work with a given driver is very important…

Still, talking about the quality of sound from compression drivers I feel it is necessary to have a common denominator – sort of a scale where the all drivers would be projected – I call it the Compression Drivers Equivalency Scale. For me in the very middle of this Equivalency is the JBL-2440 - good mix of goodies, problems and results that makes it a reliable base for Equivalency…
