Portable PA system with twin 8" drivers

The SUPERSONIC IQ-7028DJBT is a battery-powered PA speaker built around two 8-inch high-efficiency drivers and a single tweeter. It delivers 40 watts peak output and 36 watts RMS across a 40 Hz to 20 kHz range. Bluetooth 5.0, USB, micro-SD and AUX inputs cover wireless and wired sources, while a built-in FM tuner adds broadcast radio. A wired microphone, remote control and carry handles are included for immediate use.

Thermal and acoustic profile in normal use

The cabinet runs on a 7.4 V 4000 mAh rechargeable pack or the supplied 9 V 1.5 A adapter, drawing modest current at typical listening levels. Signal-to-noise ratio is rated at 78 dB, so background hiss stays low during speech or moderate music playback. Passive cooling keeps the enclosure silent when the fans are not needed, and the LED light show can be disabled to reduce power draw further.

Behaviour under sustained load

At continuous 36 W RMS the drivers maintain output without thermal compression for extended sets, making the unit suitable for seminars, parties or small-venue reinforcement. True Wireless Stereo lets a second IQ-7028DJBT pair over Bluetooth for doubled coverage. Battery runtime shortens at full power, so mains operation is recommended for all-day events. The microphone channel includes volume, echo and priority controls to manage feedback during long sessions.

Questions about this item

How do I pair two IQ-7028DJBT speakers using True Wireless Stereo, and what step do people miss?

Power on both units, press the TWS button on one speaker until it enters pairing mode, then press the TWS button on the second speaker. The step people miss is waiting for the audible confirmation tone before playing audio.

What battery maintenance does the 7.4V 4000mAh pack need, and when should I replace it?

Charge the pack at least once every three months when stored. Replace it when run time drops below roughly half of the original duration or the speaker shuts off unexpectedly at moderate volume.

At what output level does the 40W system hit its thermal limit during continuous play?

Sustained output near the 36W RMS rating will trigger the protection circuit first, causing the amplifier to reduce power until the heatsink cools.
