Our Bayside showroom houses  BMW models with both Harman Kardon and Bowers & Wilkins audio setups. The BMW i5 and i5 Touring come standard with a 205-watt, 12-speaker Harman Kardon system, with the option to upgrade to a powerful 655-watt, 17-speaker Bowers & Wilkins setup. There’s more good news if you’re considering a 5 Series. Since spring 2025, these models now include Harman Kardon speakers as standard equipment, bringing premium sound to even more drivers.

For the ultimate car audio, the BMW 7 Series features a Bowers & Wilkins Diamond audio system — widely considered one of the best audio options available today. The 8 Series also offers exceptional sound, with Coupes and Gran Coupes equipped with a 16-speaker, 1,375-watt Bowers & Wilkins system, while Convertibles use a 12-speaker configuration delivering 1,125 watts. The latest X3 BMW models round things out with a Harman Kardon 600-watt system with 16 speakers, including tweeters, midrange drivers, under-seat bass speakers, and a dedicated subwoofer.

Tech Insights: Advanced Audio Engineering

What makes these systems so impressive? In the i5, the Harman Kardon setup includes a bass speaker, a midrange driver, a tweeter in each front door, plus additional drivers in the dash and rear doors. The upgraded system in the X3 goes even further, adding more depth to the sound with a dedicated subwoofer in the cargo area.

Bowers & Wilkins takes things to another level with advanced materials and design, catering to discerning audio enthusiasts. The i5’s audio system includes dual balanced woofers, Continuum midrange speakers, aluminum tweeters, and a 7.9-inch dual voice coil subwoofer positioned between the rear seats and underfloor compartment.

The 8 Series showcases Bowers & Wilkins’ most advanced car audio technology to date. This system includes three 1-inch Diamond Nautilus tweeters (two with mood lighting), four 1-inch aluminum tweeters, seven 3.9-inch aramid fiber midrange drivers (four illuminated), and two 8.5-inch Rohacell subwoofers. With premium materials, such as diamond dome tweeters, Kevlar and Continuum cones, and Nautilus technology, the system creates sound so precise it feels like the band is playing live in your car.

Cabin Design Synergy: Acoustic Integration

BMW doesn’t just install good-quality speakers into cars and stop there. It creates a relationship between the car’s design and how sound interacts with the cabin. Its engineers understand that soft materials, such as carpets and headliners, absorb sound, while hard surfaces, including windows and plastics, reflect it. This knowledge lets them position the speakers correctly, tune each system for specific BMW models, and work with the cabin’s natural sound qualities to deliver the best audio experience.

Electric BMWs, such as the i5, are an audio paradise thanks to their exceptionally quiet cabins. Testing of the i5 Touring by TotallyEV revealed outstanding noise control: just 35-36 A-weighted decibels when stationary, 52-58 dBA when cruising at 20-30 mph, 59-63 dBA at 40 mph, and 63-67 dBA at highway speeds of 70 mph. This quiet environment gives the audio system a clean canvas to reveal subtle details in your music without competing with road or engine noise.

Hear It to Believe It: The BMW Audio Experience

The Bowers & Wilkins system in the i5 and i5 Touring sounds incredible with every music genre, from classical to hip-hop. It shines with bass and high frequencies, creating such an engaging experience that testers gave it stellar marks: sub-bass 10/10, mid-bass 10/10, mids 8/10, highs 10/10, soundstage 9/10, for an overall 9.4/10. Unlike some luxury car systems that can become tiring at high volumes, the Bowers and Wilkins remains clear and comfortable even during long drives.

A few small tweaks can totally transform your listening experience. Increase the 5-10 kHz range a bit, and you’ll get that toe-tapping feeling no matter where you’re sitting. Try different settings while playing songs you know well — use orchestral music to test how wide the sound feels, then switch to bass-heavy tracks to see what the subwoofer can really do. Use high-quality music files or premium streaming services to really hear what this amazing system can do.
