12″ Sealed Audiophile Subwoofer
Rythmik Audio F12-300 Subwoofer
This model has the same footprint as regular F12, but with different driver that allows us to use 300WRMS amps. They are currently on sale. The amplifier is HX300 with one RCA input and one mini-XLR input (a 300WRMS Hypex-based servo amplifier with a quickguide). While this model does not have a dedicated LFE input, customers can set the xover freqeuncy to maximum and crossover slope to 12db/oct. We currently extend the multi-sub discount to even a single sub purchase.
The extension filter in F12-300 sealed subwoofer is simplied to 3 positions: Low-Music, Low-HT, and high with frequency and phase response shown below. Low-music has the lowest extension, -3 db @ 17 Hz. The response is flat and extended. For high SPL in movies, we recommend Low-HT mode with built-in rumble filter that preserves the FR to -3db@18hz while reducing potentially damaging subsonic energy.
