Full Range 3 in Bookshelf Speaker Pair - Compact HiFi Sound

In this review of the Facmogu Pack of 2 Full Range Bookshelf Speakers, the bottom line is simple: these compact 3 in drivers deliver surprisingly clear, full-range sound for DIY 2.0 and 2.1 setups at a budget price. The speakers are aimed at hobbyists and small-room listeners who need a neat, anti-magnetic woofer solution that is easy to install and can handle modest power. What stood out in testing and user reports is the speakers' crisp midrange and voice coil design, which produce a sweet, intelligible presentation without requiring large enclosures.

Key Features

• 3 in compact driver: Fits small bookshelf or dash mounts and makes it easy to build tidy 2.0 or 2.1 speaker systems without large cabinets.
• Full range response: The rated 108Hz to 18kHz range provides balanced mid and treble detail for vocals and general listening in small rooms.
• Anti-magnetic design: Reduces magnetic-field interference, which helps when installing near other electronics or sensitive displays.
• 20mm big voice coil: Offers stable cone control and contributes to the speakers' clarity at typical listening levels up to the recommended power range.
• 3-band equalizer support: Allows tonal adjustment for different enclosure tuning or room preferences, improving versatility for DIY builders.
• Sold as a pair: Includes two matched 8 ohm speakers, so right and left channels are consistent for stereo imaging in compact setups.

Who It's For

These speakers are well suited for DIY audio builders, small home audio setups, and anyone wanting an unobtrusive pair for nearfield listening. They work best in compact enclosures or existing bookshelf cabinets where space and magnetic shielding matter, and they pair naturally with low-power amps in the 5 to 15W range.

People who require deep bass extension, very high power handling, or full-room concert levels should look elsewhere, as the small 3 in driver and 108Hz lower response limit the deep low-frequency output and headroom compared with larger woofers.

Pros & Cons

Pros

• Clear, sweet midrange and treble that makes vocals and instruments easy to hear.
• Compact 3.5 in outer diameter and shallow mounting depth fit into tight enclosures and dash applications.
• Anti-magnetic construction reduces interference around other electronics and displays.
• Good value for size with included accessories options such as spikes and binding posts available.

Cons

• Limited low-frequency extension below about 108Hz means bass is dependent on enclosure or a dedicated subwoofer.
• Designed for modest power; pushing well beyond the 5 to 15W range risks distortion or damage.

Our Verdict

The Facmogu 3 in full range bookshelf speakers are a sensible buy for hobbyists and small-room listeners who need compact, anti-magnetic drivers with clear mids and treble.

Frequently Asked Questions

Can these speakers be used in a car dash or similar tight space?
Yes; the compact outer diameter and shallow mounting depth make them suitable for dash mounts and other confined installations where anti-magnetic design helps protect nearby electronics.

What amplifier power is appropriate?
They perform well with low-power amplifiers in the 5 to 15W range; several customers noted they handled around 10W comfortably without distortion.

Will they produce deep bass on their own?
No; with a lower response around 108Hz these drivers lack full deep bass, so pairing them with a subwoofer or using an enclosure tuned for low frequencies is recommended.
