---

This bundle includes a Hertz SPL Show Series ST-25A-NEO 1" High Efficiency Compression Tweeters, a Hertz SPL Show SP 4.900 D-Class 4 Channel Amplifier 250 WRMS x 4 at 2Ω (IP55 rated), and a Hertz SPL Show Series SV-1651 6.5" 4-Ohm SPL Midrange Speaker Drivers (Pair).

1x Hertz SPL Show Series ST-25A-NEO 1" High Efficiency Compression Tweeters - (ST-25A-NEO)

NEO line bullet tweeters are a totally new project, lighter and more compact compared to the previous ST 25 and with superior performance thanks to the use of Neodymium N38 H for the motor units and a FEM (Finite Element Method) optimized driver/horn design. The “Active” version, ST 25A Neo provides tweeter only.

Features -
• Powerful Neodymium magnet providing high performance with compact size.
• FEM (Finite Element Method) optimized phase-plug and loading horn.
• CCAR (Copper Clad Aluminium Ribbon) voice coil for unheard-of thermal and mechanical capability ready for an easy replacement with replacement body kit.
• Extra-light aluminium membrane to maximize SPL with high current, screw terminals.
• Body waterproofing and anti-UV treatment to allow safe outdoor use without discoloration over time.
Specifications -
• Size mm (in.): 44 (1.8) • Power Handling - Peak W: 100 Hi-pass filtered @ 5 kHz - 12 dB Oct. • Impedance Ω: 4 • Frequency response Hz: 3k ÷ 20k • Sensitivity dB SPL: 107 • Voice coil Ø mm (in.): 25 (1)

1x Hertz SPL Show Series SV-1651 6.5" 4-Ohm SPL Midrange Speaker Drivers (Pair) - (SV-1651)

The SV 165.1 car audio midrange can be employed to build systems with tremendous impact. Like the SX subwoofers, the SV 165.1 features a solid, robust structure and, like all the other SPL Show components, it employs a copper voice coil wound on a two-layer KSV former, for unheard-of thermal and mechanical capability also in extreme circumstances. The cone features a water repellent pressed paper membrane and paper dust caps, both robust and light weight, as well as double-wave damped fabric surrounds to ensure linearity even under extreme conditions, contributing to high SPL scores.

Features -
• High magnetic permeability plates provide constant, even flux.
• High density flux ferrite magnet, for top SPL performance.
• Double layer copper voice coil, wound on KSV former; for excellent thermal and mechanical capability.
• High current, tin-plated terminals.
• Damped fabric surround; for maximum lightness and extreme SPL.
• Water-repellent, pressed paper cone.
Specifications -
• Size mm (in.): 165 (6.5)
• Power Handling - Peak W: 400
• Impedance Ω: 4
• Frequency response Hz: 100 ÷ 10k
• Sensitivity dB SPL: 97
• Voice coil Ø mm (in.): 38 (1.5)
• Magnet: High density flux ferrite
