Muy buenos
Muy recomendables, lo uso combinados con parlantes antiguos en cajas de 3 way; La respuesta sonica es muy pareja y bastante detallada, dejando a la luz todo contenido con muy agradable nivel y sin duresas. sin duda alguna pueden hacer la inversion con seguridad.

Got this driver to replace a three way speaker system from the mid 80's. I didn't know its crossover points. However, the old tweeter was a 4ohm non vented 19mm soft dome design, which lead me to the conclusion the crossover point should be rather high (3000 hz or +).
So, I took a guess this SB would do the job of injecting "air" and liveness to the sound (the old driver had a somewhat sibilant and lacklustre, dirty sound).
And I guessed right! After some break in, this very nice buit tweeter sounds incredibly clean and open, transforming the old system totally. By the way, it's fast and very dinamic too!
I'm pretty knew to the DIY hobby, but I think that, with a better crossover and in an overall better speaker system design, this tweeter might work miracles!
