Customers are satisfied with the sound quality of the speakers. They mention that it greatly improves their overall sound, and the bassist can hear through the cacophony. They also say that by isolating electronics, all music is sharper and less blurry. Customers also mention that the tone is overall much tighter and clearer, and that the whole band can hear them clearly. They say that the speakers are able to isolate the sound, giving it definition, and allowing them to play with a bit more onstage volume.

7 customers mention7 positive0 negative

Customers are satisfied with the size of the speakers. They mention that it works perfectly, is surprisingly heavy, and fits perfectly onto the receiver's platform. The speakers are large enough to hold their cabinet with nothing leaking over the sides. They are great for a small rig and eliminate vibration but not the rumble of the bass cab.

5 Stars
I'm really isolated now.
Although the results may vary for everyone else. I placed my subwoofer for a Q80r Soundbar on top of this on a concrete floor ; its weird that the bass sounds louder for me but pretty much nonexistent for everyone outside my space. Although the price went up I highly recommend this product. The money is worth it if your looking to turn the volume up and not annoy anyone.

5.0 out of 5 stars Efectivo y sólido para altavoces Klipsch Cornwall
Reviewed in Spain on September 6, 2022
Lo he colocado sobre unos altavoces Klipsch Cornwall, que son de gran tamaño y no tienen pies ni sistema de desacople del suelo. Hay quien diseña soportes de madera, que son bonitos pero técnicamente no sirven para aislar el altavoz de las vibraciones del suelo.
Este Auralex Gramma V2 tiene un tamaño perfecto para colocarlo bajo las Cornwall, añaden 5 cm de altura a las cajas, lo que tampoco les viene mal, y la única pega es que no deslizan sobre suelo de madera, por lo tanto hay que hacer un buen esfuerzo si quieres variar un poco la posición de las Cornwall para la escucha. ¿Solución? Muy sencilla. Se cubre la base de las Auralex con fieltro autoadhesivo negro de 1mm de espesor y entoces sí, las Cornwall se deslizan con facilidad y además no rayan en absoluto el suelo.
Una vez instalado el Auralex bajo cada altavoz, la diferencia en el control de las frecuencias bajas es muy notable y las Cornwall suenan aún mejor. Sí, es un gasto un poco elevado (cerca de 175 euros en total) pero es para toda la vida y merece la pena por las evidentes mejoras en el comportamiento acústico de estos magníficos altavoces colocados sobre las Auralex Gramma V2. 100% recomendable.
