Quick answer
Choose the KaraokeBox 500 if you want a compact, affordable karaoke and PA system with an adjustable mic stand and built-in phone holder for casual home parties. Choose the Karaokebox 2100R if you want a larger 14.1-inch touchscreen Android tablet, dual 10-inch woofers, and HDMI output for a more interactive, feature-rich karaoke setup.
Karaokebox 2100R
The KaraokeBox 500 and Karaokebox 2100R are both karaoke speakers from Dolphin, but they solve different problems. The 500 is a portable, budget-friendly system built for quick setup and easy singing at home. The 2100R is a step up in size and control, adding a large touchscreen tablet and dual woofers for a more produced karaoke experience.
This comparison uses the supplied catalog facts to show where each model fits, so you can match the speaker to your room, your crowd, and how you like to run a party.
Price and value: what you pay for
The KaraokeBox 500 is listed at USD 85.00, compared with a catalog comparison price of USD 169.99. It includes an adjustable mic stand, a built-in phone holder, Bluetooth streaming, and LED lights that react to your music. For a first karaoke setup or a gift, that combination keeps the entry cost low while still covering the basics of singing and streaming.
The Karaokebox 2100R is listed at USD 249.50, compared with a catalog comparison price of USD 499.00. The higher price reflects a built-in 14.1-inch touchscreen Android tablet, HDMI output, dual 10-inch woofers, and voice modulation with sound effect buttons. You are paying for a more self-contained system that does more without extra gear.
- If your budget is under USD 100, the KaraokeBox 500 is the straightforward pick.
- If you want a screen and effects built in, the Karaokebox 2100R avoids the need for a separate tablet or TV.
Control and interface: phone holder vs built-in tablet
The KaraokeBox 500 uses a built-in phone holder and Bluetooth streaming, so you bring your own phone or tablet to run lyrics and music. That keeps the hardware simple and familiar, but it means your screen size and app choice depend on the device you already own.
The Karaokebox 2100R integrates a 14.1-inch touchscreen Android tablet running Android 12, plus HDMI output for display options. You can manage songs and settings directly on the speaker, and send video to a TV or projector when you want a bigger lyric screen. The trade-off is a larger, heavier unit that stays closer to home.
- Phone-holder setups are easier to upgrade later because you can swap in a newer phone.
- A built-in tablet is more convenient for guests because there is no pairing or app setup on their part.
Sound and room size: dual 10-inch woofers vs portable format
The Karaokebox 2100R is built around dual 10-inch woofers, which suits a living room, garage, or small hall where you want fuller low-end for backing tracks. The catalog does not list wattage for either model, so treat room size and speaker configuration as your practical guide rather than a wattage number.
The KaraokeBox 500 is described as a portable karaoke and PA system with powerful sound, Bluetooth streaming, and WaveSync technology. It is designed for performances, parties, and events where you want quick setup rather than maximum output. If you regularly host 20 or more people, the 2100R's larger drivers are the more comfortable choice.
- Match the speaker to your typical guest count, not to a spec sheet alone.
- If you need to move the system between rooms or outdoors often, weight and setup time matter as much as driver size.
Setup and portability: which one travels better
The KaraokeBox 500 includes an adjustable mic stand and a built-in phone holder, and it is positioned as a portable system. That makes it easy to set up on a table or stand and start singing without a fixed installation. It is the better fit if you store your karaoke gear in a closet between parties.
The Karaokebox 2100R is a larger integrated machine with a tablet, dual woofers, and dual wireless microphones. It is better thought of as a semi-permanent home entertainment piece. The catalog does not list a carrying handle or wheels for the 2100R, so plan for a dedicated spot rather than frequent transport.
- Measure your storage space before choosing the larger 2100R.
- If you host in different rooms, a lighter system with a stand is less hassle.
Trade-offs to weigh before you buy
- Price vs built-in screen: The KaraokeBox 500 costs USD 85.00 and relies on your phone, while the Karaokebox 2100R costs USD 249.50 and includes a 14.1-inch Android tablet. Pick the 500 to save money; pick the 2100R to avoid bringing your own screen.
- Portability vs output: The KaraokeBox 500 is a portable system with an adjustable mic stand, while the Karaokebox 2100R uses dual 10-inch woofers and a larger integrated body. Choose the 500 if you move your gear often; choose the 2100R if it can stay in one room.
- Simple setup vs advanced features: The 500 covers Bluetooth streaming and reactive LED lights, while the 2100R adds HDMI output, voice modulation, and sound effect buttons like applaud and laugh. Decide whether you want a straightforward sing-along or a more produced karaoke experience.
