Midrange and tweeter performance
The 100 mm (4 in) midrange uses a water-repellent pressed-paper cone for natural sound reproduction. Its low resonance frequency allows a hi-pass cut-off in the 150–200 Hz range for excellent mid-low performance.
The 25 mm Tetolon dome tweeter delivers strong extension across medium and high frequencies and is optimised for off-axis output, helping to create a wide, three-dimensional sound stage. If you are looking for a universal Audison Prima option, the Audison Prima APK 165P is a 6.5-inch 2-way component kit available for general fitment.

About the Audison APBMW K4M
From our tech experts at CEN
The Audison Prima APBMW K4M is a 2-way component speaker kit designed specifically for BMW and Mini, pairing a 100mm (4") midrange with a 29mm Tetolon dome tweeter. Rated at 50W continuous and 100W peak, it runs at 4 ohms. Plug-and-play connectors allow direct fitment into factory speaker locations without cutting wires.
Who it suits
BMW and Mini owners who want noticeably improved sound staging without modifying the car's wiring will find this kit a clean, straightforward upgrade. Those who prefer a simpler coaxial drop-in can consider the Audison Prima APBMW X4M instead.
Our tech experts advise
The kit ships with a crossover, tweeter support and a 30cm extension cable, which covers most factory mounting positions. The tweeter level adjusts between 0 dB and -3 dB to balance output with your head unit. Installation is priced per vehicle; see our Nottingham car audio fitting page for details.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: Do I need to cut any wiring to fit the Audison APBMW K4M?
A: No. The basket, crossover and supplied 30 cm extension cable all use Plug and Play connectors, and a tweeter support is included for the OEM tweeter positions.
Q: What size are the Audison APBMW K4M speakers?
A: The kit uses a 100 mm (4-inch) midrange/woofer and a 29 mm Tetolon dome tweeter, both with 25 mm voice coils.
Q: Can the APBMW K4M tweeter level be adjusted?
A: Yes. The tweeter level can be set to -3 dB or 0 dB to suit your car and listening preference.
