Alpine R2-S652 Next-Generation R-Series 6.5″ (16.5cm) Hi-Res Audio Certified Component 2-Way Speaker System

WOOFER / MID-BASS DRIVER (6.5″ / 16.5cm)

• Speaker Size & Frame Structure: Standard 6.5-inch (16.5cm) door woofer built on a rigid cast frame that stops chassis resonance and acoustic energy loss.

• Glass-Fiber Reinforced Cone: Built with a stiff, ultra-lightweight composite glass-fiber cone that moves swiftly without bending under high volume. This eliminates sound flex distortion even during heavy bass passages.

• HAMR Surround (High-Amplitude Multi-Roll): Alpine’s patented HAMR multi-roll rubber surround permits extended cone travel while keeping it strictly linear. This results in tight, deep, and highly authoritative mid-bass output.

• High-Flux Ferrite Motor: Powered by an oversized magnet structure for consistent voice-coil control and high power output handling.

HIGH-PERFORMANCE TWEETER (1″ / 2.5cm Magnesium Dome)

• Magnesium Hard-Dome Design: Utilizes ultra-light magnesium metal domes that comfortably play up to 40,000 Hz (40 kHz), easily qualifying for Hi-Res Audio certification without causing ear fatigue or high-end harshness.

• Swivel & Custom Mounting Versatility: Features a built-in swivel mechanism to aim high frequencies directly toward the listener’s ear level for accurate imaging. The outer housing can also be detached for OEM-style flush fitting inside factory A-pillars.

FULL-SIZED EXTERNAL CROSSOVER NETWORKS (How It Works)

• How Crossovers Work: A crossover acts as an audio router. It receives the amplified full-range audio signal and cleanly divides it: routing low and mid frequencies exclusively to the 6.5″ woofer while channeling pure high frequencies to the magnesium tweeter.

• Audiophile Passive Components: The R2-S652 includes heavy-duty external crossover housings equipped with premium induction coils and film capacitors. This keeps total harmonic distortion (THD) near zero and protects the drivers from overload.

• Adjustable Tweeter Output: Features built-in terminal pin/jumper adjustments (-3dB / 0dB / +3dB) so installers can fine-tune the tweeter loudness according to the car’s interior cabin acoustics.

FREQUENCY RESPONSE, IMPEDANCE & POWER RATINGS

• Frequency Range (65Hz – 40,000Hz): Captures everything from deep vocal bass notes (65Hz) to ultra-high frequency harmonics (40kHz) necessary for lossless/uncompressed audio formats.

• Power Handling: 100 Watts RMS continuous power (300 Watts Peak), ideal for powering via 2-channel or 4-channel high-output car amplifiers.

• 4-Ohm Impedance & 88dB Sensitivity: Standard 4-ohm impedance load with an efficient 88dB sensitivity rating for effortless amplification.

TECHNICAL SPECIFICATION INDEX:

❓ WHY CHOOSE THE ALPINE R2-S652 SYSTEM?

1. Hi-Res Audio Certified Precision: Built specifically to reproduce master-quality lossless music files (FLAC, WAV, DSD) with total studio fidelity.

2. Pro-Grade External Crossovers: The enlarged external crossover boxes offer superior heat dissipation and cleaner signal separation than smaller in-line filters.

3. Zero High-Volume Distortion: Glass-fiber cone rigidity paired with HAMR rubber surrounds maintains tight control even under heavy sound pressure levels.

4. Custom Soundstage Imaging: Swivel tweeters allow precise directional control of high frequencies directly toward your ears.

5. Durable Premium Build: High-grade cast frame construction prevents unwanted resonance inside car door cavities
