This is the frequency response of our loudspeaker Spear. The measurement is taken in a standard living room. The low frequency reproduction starts at 25Hz and represents an extremely low value. The upper frequency goes well over the measured band of 20 000Hz.

Here you see the impuls response of our 6.5" Polyepicell woofer. This represents an excellent impuls reproduction. The frequency response shows are very smooth curve up to 3500Hz where the woofer rolls off naturally. This is the crossover frequency and eliminates the need for steep filters.

On the left the frequency response of our Polyepicell 5 inch woofer is shown. The frequency response is very flat and drops off naturally at the crossover frequency, eliminating the need for passive crossover components.
