Buenas, no se si alguien lo habra visto, pero no he visto nada sobre este tema por aqui, asi que aqui va: EVANS ha sacado una nueva serie de parches, los EC2 (edge control 2 plies), que vienen a ser como los G2 pero llevan una especie de sordina en plan como el EQ3 para bombo. Prometen bastante y su mayor baza parece ser la de funcionar muy bien tanto a altas como a bajas tensiones de afinacion.

Y aqui los comentarios al respecto del propio admin del foro de evans, un tal Mike Robinson que seguramente sepa un rato:
A ver si alguien se entera de como se pilla esto porque puede ser interesante probarlos. En music123 creo que ya estan a la venta pero no esta la cosa como pa pedir un juego de parches a los USA...
Saludos!

Mike Robinson dijo:Hello All,
Mike Robinson here...the Brand Manager for Evans. I'm sure some of you might remember me from the darker days of DrumTalk (good to see you back, Harry). Just thought I'd jump in briefly to offer a little more in-depth of an explanation with regard to the EC2. Obviously, no single drumhead is going to be the "fix all" solution for everyone, so the only way to know whether the EC2 fits your personal taste is to give one a try. You'll likely find them soon at professional drum shops around the US, where they may wind up on an in-store kit so you can try before you buy. As noted, the sticker price on these are a little higher than average, so if you have the chance to check them out on a kit before you drop the $...it's a good idea. Anyway, here's the concept...
Age Old Problems - With regard to 2-ply tom heads, there are two relationships that will make or break the quality of sound you get. First is the relationship between the head and bearing edge. Okay, no surprises here...but it's an important point. The minute you introduce another element between the head and bearing edge, whether it be a flap that rides between them or glue between the plies, you disrupt the ability of the head to vibrate naturally. The motion of the head is restricted/compromised at its most crucial point. Tune this type of head high and it chokes. Tune it low and it gets tubby or flappy sounding.
The second relationship is between the two plies themselves. A good sounding two-ply is the result of the two pieces of film being able to vibrate freely from each other and also "in-phase", which means at the same frequency. If the two plies were to immediately vibrate out-of-phase, or at opposing frequencies, they'd cancel each other out and you'd be left with a dull and lifeless sounding head. It's important to let the two plies vibrate freely and in unison for the first 4 modes of development, wherein lies the attack and fundamental frequency (or pitch). After that, the plies should start to cancel each other out...which is why the sustain drops off more suddenly on a two-ply compared to a single-ply. Unfortunately, this relationship is disturbed when you put something between the two-plies...like glue (pardon the obvious reference here). Immediately, the free vibration of the two plies is limited and it's much harder to excite those first 4 modes. The result is a lack in dynamic range. You need to hit these types of heads hard to get the whole drum to resonate. Soft dynamics result in a "ticky" top-head sound with very little movement of the air-column inside the drum.
After I explain the following...I'm sure some of you will come back and say it's all marketing spin. That's fine...and we certainly ARE using this information in our marketing of the EC2...but it's also the honest design intent behind these new heads.
The Solution - "EC" stands for "Edge Control". The intent is to boost attack and low-end response, and to isolate higher frequencies and remove them without significantly degrading sustain, drum resonance, tuning range, and/or dynamic range. To accomplish that, the EC2 features a ring mounted on the underside of the head (beneath both plies...not between them) and does NOT come between the bearing edge and the vibrating membrane. Depending on the bearing edge shape and shell dimensions, it floats roughly 1/4" away from the edge (see attached image). Already, we've avoided the two pitfalls mentioned above. We've avoided interfering with the relationship between the head and bearing edge, and between the two plies. We also made the ring width proportional to the head diameter...so the character of sound remains consistent across all drum sizes. Lastly, we cut "stress-relief" slots in the ring (note concentric segmented slots/gaps in the center of the ring). Those slots (similar in principal to our Power Center snare heads) allow the ring to flex with the vibration of the head. When combined, all these design features give the EC2 a broader tuning and dynamic range, and accentuate attack and low-end frequencies. The head and drum respond with the same feel and tonal character (good frequency spread) in extreme tuning and dynamic ranges. Just tap the head softly and the drum still sings. Hit it hard and it's just a higher volume version of itself. Tune it high and it won't choke. Tune it low and you'll get fat bottom-end and crisp attack without the tubby sound typical of traditionally damped heads.
Sorry for the ridiculously long-winded explanation, but I felt it important to share the concept with you. Again, the EC2s are not intended to be a fix-all for everyone. You'll have to check them out and see for yourself whether they match your personal taste. But I want to be clear that there was no copying of anyone elses designs or concepts. We worked hard on this project for 5 years before we felt satisfied to launch it. I hope some of you like it. We're certainly proud of it.
Thanks,
Mike
