SUPER POWER AUDIODESIGNED IN ITALY

100 watt RMS.
It goes where the old one was.
A two-way coaxial: woofer and tweeter on the same axis, in one frame. 5"/13.5 cm, 85 dB, 4 ohm. It replaces the factory speaker in the original hole — no external crossover, no tweeter to mount separately, two wires and it plays. Sold as a pair.

Why this coaxial
The high notes come from a tweeter mounted on the same axis as the cone. One speaker, one hole, one pair of wires: the sound stage stays where the factory speaker was.
The filter for the tweeter is already inside. Nothing to hide behind the door panel, nothing to wire, nothing to set.
Injection PP, black, rubber surround. Injection-moulded polypropylene does not soften with damp or heat, and the rubber surround keeps working after years inside a door.
135 mm nominal, 4 ohm. In most cars it drops straight into the factory location and sounds far better than the speaker it replaces.

Complete the system
Before you install it
- Measure the hole and the depth first. A coaxial is deeper than a plain woofer, because the tweeter sits above the cone. Check the 5" cut-out and the free space behind the door panel or the window mechanism before you order.
- Do not go below 4 ohm per channel. Two speakers in parallel on one channel give 2 ohm: most head units and small amplifiers will heat up or go into protection.
- With a powerful amplifier, use a high-pass filter. Cut below 95 Hz and leave the bass to a subwoofer. Feeding deep notes to a coaxial is the fastest way to damage it.
- Seal the door panel and respect the polarity. Sound-deadening the panel and wiring both speakers in phase change more than any setting on the head unit.
