1)  8" Woofer with Monster Low-End 
– The oversized 270Z ferrite magnet and compressed cotton-fiber pulp cone deliver deep, punchy bass that smaller speakers simply can't match. Perfect for listeners who want chest-thumping lows without a subwoofer.

2)       The Challenge: Taming the Bass 
– With such powerful low-frequency output, most 8" systems sound muddy or unbalanced. That's why Edge engineered a high-end 28mm (1.1") silk dome tweeter with a rear chamber – to deliver smooth, extended highs that keep up with the massive bass. The result? Perfect tonal balance.

3)       Rear-Chamber Tweeter for Crystal Clear Highs 
– Unlike cheap tweeters that sound harsh, our 1.1" soft dome tweeter features a built-in rear chamber with sound-absorbing material, reducing resonance and delivering natural, fatigue-free treble even at high volume.

4)       Aluminum Basin Frame + High-Temp Voice Coil 
– The woofer frame is built from stamped aluminum for rigidity and heat dissipation. The 1.4" KSV high-temperature voice coil handles serious power without failure – 160W RMS / 320W Max for RPM38.

5)       Custom High-Performance Crossover 
– Each system includes Edge-customized crossovers with high-grade Mylar capacitors and automatic thermal protection. RPM38 adds a dedicated midrange crossover at 1,300Hz/12dB.

6)       3-Way Design for Ultimate Soundstage 
– Adds a 3.5" neodymium magnet midrange dedicated to vocals and instruments. This takes the load off both the woofer and tweeter, resulting in smoother midrange, lower distortion, and a more immersive listening experience.

7)       Adjustable Tweeter Attenuation & Phase 
– Under the removable cover, you'll find -3dB/0/+3dB tweeter level adjustment and 0/180° phase switch. Fine-tune your system to match your vehicle's acoustics – a feature usually found only on high-end home audio speakers.
