Acoustic data

Broadband control where bass builds up

The triangular trap fits into the corner, where low frequencies build up and standing waves form. Its response also covers the midrange, so it works where broader control is needed than a round design can offer.

90-2000 Hzdeclared absorption range

α = 1,00at 160 Hz on the curve

50-2500 Hzdata range on the chart

At 100 Hz the curve reaches α = 0.86, and at 125 Hz α = 0.96, showing effective performance in the bass.
The maximum of α = 1.00 occurs at 160 Hz; at 200 and 250 Hz the values are still 0.97 and 0.96.
In the 315-630 Hz range the coefficient holds at 0.90-0.95, supporting midrange control.
The curve stays active above 1 kHz: α = 0.85 at 1600 Hz and α = 0.76 at 2000 Hz.

Sound absorption coefficient α

Measurement conditions: sound absorption coefficient α; temperature 23°C, relative humidity 48%.

Encaja muy bien en la esquina y el bajo suena más limpio. Para las notas más graves harían falta varias, pero por lo demás contento.

Tucks neatly into the corner and the low end is noticeably more controlled. Took a couple of them before the effect was really obvious though.

La forme triangulaire épouse parfaitement l'angle et le grave est mieux maîtrisé. Bon rapport qualité-prix.
