Additional Notes
- The 1985 BMW 535i uses 4x6 inch openings in both front kick panel and rear deck lid locations, suggesting a straightforward replacement approach with matching full-range speakers across all positions.
- Full-range speakers represent the compatible type for all factory locations, indicating these positions were designed to handle the entire audible frequency spectrum without requiring separate tweeters or woofers in those specific mounting areas.
- Kick panel placement in the front positions typically directs sound upward toward occupants, while the rear deck lid location fires sound into the cabin from behind, creating a front-to-rear sound distribution pattern.
- The 4x6 inch rectangular format offers more cone surface area than circular 4 inch speakers while fitting into relatively compact dashboard and deck spaces common in vehicles from this era.
- Aftermarket replacement speakers in this size category often feature improved materials like polypropylene cones and textile dome tweeters compared to original equipment, potentially enhancing clarity and frequency response.
- Single DIN radio specification indicates a standard 7x2 inch opening for head unit upgrades, which could complement speaker replacements when pursuing overall system improvements.
- The absence of separate component locations suggests the audio system relied on full-range drivers to reproduce all frequencies, rather than dedicated midrange, tweeter, and woofer combinations found in some factory configurations.
