The Klipsch Gig XXL is a large-format portable Bluetooth party speaker built for powerful, high-clarity sound and all-night entertainment. Driven by two 6.5-inch full-range cone woofers and two 2-inch dome tweeters in a bass reflex enclosure with a rear-firing port, it delivers a maximum acoustic output of 110.7 dB with a frequency response of 50–20,000 Hz (±3dB). A dedicated Bass Boost mode amplifies low frequencies for deeper, room-filling bass. Klipsch's 70-plus years of audio engineering is reflected in the speaker's dynamic range and legendary clarity.

Connectivity options are extensive. Bluetooth 5.0 streams music wirelessly from smartphones, tablets, or computers at ranges up to 33 feet, supporting A2DP streaming and AVRCP playback control. Two Gig XXL units can be paired via True Wireless Stereo (TWS) for an expanded stereo soundstage. A 3.5mm stereo aux input accepts virtually any analog audio source, and the matching aux output allows daisy-chaining a second speaker or connecting a recording device. A USB-A 2.0 port plays MP3 and WAV files from flash drives and also charges USB-enabled devices at 5V/1A. Two 1/4-inch inputs with independent gain controls accept the included wired microphone (9.75-foot cable) and an instrument such as a guitar or keyboard simultaneously, enabling karaoke and live performance scenarios.

The speaker features two multi-color RGB lighting rings and dual strobes with multiple selectable modes that pulse to the beat of the music. Top-panel controls include four rotary dials and seven push-buttons managing power, volume, mic level, guitar level, echo effect, light effects, bass boost, and playback. The built-in rechargeable lithium-ion battery provides up to 8 hours of playtime and recharges fully in approximately 3 hours via the included 58-inch detachable AC power cord (C7 connector), which can also power the speaker continuously from a wall outlet. An integrated carry handle makes transport straightforward. The unit measures 10.75 inches wide by 21.875 inches tall by 11.3125 inches deep, weighs 18 pounds, and must be oriented vertically. It is not rated for weather, water, dust, or shock resistance. Warranty is 1 year on the amplifier and 3 years on the speaker drivers.
