Собсно, вот все, что там есть... Одна страничка...

The spectacular DB-speakers offer, in addition to an attractive design based on individual HELIX-baskets
and HELIX-grilles, steady sound quality with a clear and powerful mid/bass reproduction.
The small mounting depths account for an easy installation in any car.

Features:
• 5.25 inch mid/bass
• 25 mm soft dome tweeter
• injection-moulded woofer diaphragm for avoiding disruptive resonance
• special rubber edge surround for high loadability and long operating time
• universally applicable Euro-DIN baskets in individual HELIX-design for easy installation in virtually any vehicle type
• delivery contents: 2 mid/bass speakers, 2 tweeters, 2 crossovers, 2 grilles
