Comparing two guitars: TORRES and NOMEX Double Top 

Essentially a double-top (DT) is like collection of cells in honeycomb pattern forming a collection of little drums sitting side by side. It is facilitated by the Nomex sandwiched between 2 thin pieces of wood. Just imagine, a banjo is one large drum, but DT is a collection of little drums organized in cell pattern. Each honeycomb cell is hollow. So Nomex is not just a reinforcer, but it forms small hollow cells in between 2 layers of woods as well. The application of glue must be very careful not to spill it over to the cells. It produces so much volume, because it is like beating hundreds of little drums at the same time. Using other material, e.g. balsa will work, because it is still forming those little drums.

Thank you! Now i understood the incredible difference in volume between the two types of guitar

If both were being offered for sale in a store I'd walk out with the Torres copy, just based on the sound samples I heard. The double top sound is very "heavy". I prefer a lighter tone. It projects just as much.

I used to own a double top guitar by a reputable luthier and was forever trying to warm it up. I was told that the air in the cavities in the top generated by the nomex had to be energised through playing. I found it most frustrating, particularly as I tend to practice in short bursts rather than long periods. Has anyone else had this problem? By the way, I like to call them composite tops so as not to confuse them with the Contreras design.

I doubt that Segovia, Bream, or Williams had any problems with volume or projection in the great concert halls playing a traditional classical guitar.

Thanks for sharing....

Excellent

very interesting

3:50. WOW

3:44 no one has ever had the edge of an acoustic guitar cut into their arm because of no arm rest.

NOMEX and SOUND PORTS.....silly affectations. Sterility at its best.

Don't talk so much. Demonstrate.

None of this is valid. More guitar myths. Stop it.

Sound 0,1% Bla bla bla bla bla bla...99,9%

Very interesting video, nice guitars and sounds too. Regards, Phil.

Esse segundo violão o som lindo,E a beleza incomparável á qualquer violão.

Louder yes but the tone on the fan braced top still sounds sweeter to me - of course listening to a recording can't make up for the real thing but still, I would give up the volume for the tone.

thank you for your quick reply. what's DT. If you choose only one through Spanish and yulong guo, which one would like to choose? because? Ted from HI of USA

Have you further opened the port on the side? (Good description BTW!)

The elevated fingerboard on the classical guitar is not a modern innovation. Johann Stauffer made early guitars in the 1800's with elevated fingerboards,way before Humphrey and other makers.

conclusion, which one do you prefer to?? ted from usa

Too much talking and too less playing
