🔊 Application and configurations

1️⃣ Powering a pair of speakers

The GTX800.2D is ideal for powering two speakers.
Built-in high-pass crossovers (HPFs) eliminate the lowest frequencies that could overload speakers, especially those with smaller diameters.
The result is clean, clear sound without distortion .
The additional ability to boost high frequencies improves the spatial dimension of the sound, especially in cars where speakers are placed low in the doors or at the rear of the cabin.

2️⃣ Subwoofer Power Supply

GTX800.2D amplifier can be configured in bridge mode , combining the power of both channels to drive a single subwoofer with a minimum impedance of 4Ω .
The low-pass crossover (LPF) allows you to set the appropriate frequency response so that the subwoofer reproduces only the low frequencies.
This allows:

• the subwoofer does not heat up unnecessarily,

• the entire power of the amplifier is used to reproduce the bass,

• There is an option to boost low frequencies , which allows you to get an even more powerful bass impact.

⚠️ Minimum subwoofer impedance: 4 Ω
For 1 Ω or 2 Ω subwoofers, a monoblock (single-channel) amplifier from the GRAVITY GTX series is recommended.
