Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 918-495-0586 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

EXTRA BASS adds power to every bassline

Push the EXTRA BASS button to add some serious low-end power to your music. It works by reinforcing basslines to create deep, punchy bass. Simply press the button to activate the mode and be blown away by resounding bass.

Vertical and horizontal setting

A flexible two-way setup gives you great sound, wherever you place the system. Set it up horizontally for a classic boombox feel or flip it upright if you're short on space. A built-in sensor optimizes how sound is processed to stereo sound, whichever setup you choose.

Just like being there

Hear your music in a whole new way-just hit the LIVE SOUND button and cleverly angled speakers and DSP technology send your music to a wider area. Bring your party to life with a unique three-dimensional sound experience, creating festival vibes wherever you go.

Light up the party

The GTK-XB72 has built-in multi-coloured LED line lights on the front, sides and top, pulsing speaker lights within the main body, and a flashing strobe light for added impact. The perfect way to create a club-like atmosphere.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.
