Complete Your Front Stage: NVX X-Series 2.5" & 3.5" Neodymium Midrange Drivers

The NVX X-Series Midrange Driver Lineup features the XQS2 (2.5") and XQS3V2 (3.5" V2). These speakers are engineered to fill the acoustic gap between door-mounted mid-bass woofers and high-frequency tweeters.

The X-Series is NVX’s flagship audiophile tier and so the Midrange Driver Lineup gets authentic woven carbon fiber and anodized aluminum cones, Neodymium motor assemblies, and oversized voice coils for ultimate competition-grade precision.

Who Is the NVX X-Series Midrange Series For?

The X-Series midrange lineup is engineered for audio enthusiasts looking to upgrade a standard speaker setup into a fully articulated 3-way front stage:

• Custom 3-Way System Builders: Audiophiles and SQ competitors looking to fill the acoustic gap between door-mounted mid-bass woofers and high-frequency tweeters for competition-grade vocal realism.
• Drivers Seeking Ear-Level Vocals: Vehicle owners who want to lift critical vocal frequencies and instrument detail off the floorboards and position them directly in front of the listener at dash level.
• Installers Working with Tight Dash & Pillar Spaces: Builders needing compact Neodymium motor profiles that easily clear shallow dashboard subframe supports, air ducts, and A-pillar trim without heavy custom fabrication.
• Owners of Expandable 2-Way Component Kits: System builders who own expandable component setups (such as the XQS65KITV2) and want to add dedicated 2.5" (XQS2) or 3.5" (XQS3V2) drivers using switchable 3-way crossovers or active DSP channels.

Why Add Dedicated Midrange Drivers to Your Front Stage?

Expanding a standard 2-way system into a true 3-way setup transforms the vocal presence and instrument separation on your dashboard:

• Lifts Vocals to Ear Level: Placing dedicated 2.5" or 3.5" midrange drivers in dashboard corners, upper A-pillars, or factory dash locations moves critical vocal frequencies off the floor and directly in front of the listener.
• Reduces Distortion on Door Woofers: By relieving door-mounted 6.5" or 6x9" woofers from reproducing vocal frequencies (300 Hz to 3.5 kHz), the lower woofers can focus exclusively on delivering deep, hard-hitting mid-bass.
• Compact Neodymium Motor Efficiency: High-density Neodymium magnets supply strong magnetic motor flux in shallow physical profiles, allowing drivers to clear tight dashboard subframe supports, air ducts, and pillar trim.
• Seamless Multi-Way Crossover Integration: Both drivers integrate seamlessly into active DSP configurations or expand existing 2-way systems (such as the NVX XQS65KITV2 Component System )using its switchable 3-way passive crossover network.

Exploring the X-Series Midrange Drivers

Installer Note: While dashboard and pillar cutouts vary significantly across vehicle makes and model trim levels, the XQS2 includes a single multi-fit mounting adapter with break-off tabs that you adjust for your specific vehicle. Always verify your mounting depth using the NVX Vehicle Selector on NVX.com before ordering!

XQS2 | 2.5" Neodymium Midrange Driver Pair

• Sound Profile: Clear vocal reproduction and consistent mid-range detail, filling in dialogue frequencies between door woofers and dash tweeters without adding harshness.
• Power Rating: 100W RMS per pair (50W RMS each) / 200W Peak
• Primary Fitments: Factory dashboard corners, upper A-pillar pods, and center channel locations in modern vehicles.
• Included Accessories: Multi-fit mounting adapters with break-off tabs for direct bolt-in fitment in GM, Mopar, Toyota, Subaru, and Mercedes dashboards.

XQS3V2 | 3.5" V2 Carbon Fiber Neodymium Midrange Driver Pair

• Sound Profile: Full mid-range tone and clean instrument detail, adding lower mid-range body to vocals while bridging the transition between door mid-bass and high-frequency treble.
• Power Rating: 100W RMS per pair (50W RMS each) / 200W Peak
• Primary Fitments: 3.5-inch factory dashboard openings, custom fiberglass A-pillars, and 3-way active front-stage builds.

How to Power & Tune Your Midrange Drivers

Recommended Amplification

To maintain linear cone motion and detailed vocal output, power your X-Series midrange drivers with 35W to 75W RMS per channel using a clean multi-channel Class-D amplifier such as the NVX VADM4 Micro Amplifier.

Recommended Crossover & Bandpass Settings

When integrating dedicated midrange drivers into a 3-way active DSP or amplifier configuration, set a Bandpass Filter (HPF + LPF):

• High-Pass Filter (HPF): Set between 250 Hz and 350 Hz (12dB or 24dB slope) to block low frequencies and protect small voice coils from thermal damage and mechanical over-excursion.
• Low-Pass Filter (LPF): Set between 3.5 kHz and 5 kHz to pass high frequencies off to your silk dome tweeters smoothly.

Filtering out sub-250Hz bass protects small 1-inch voice coils from overheating during extended listening sessions at high volumes.

DIY Tips for Dashboard & Pillar Installation

• Angle Drivers Toward Listeners: Aim dashboard- or pillar-mounted midrange drivers on-axis toward the cabin center to establish a wide, realistic soundstage across the windshield.
• Seal the Driver Baffle: Ensure the back of the midrange frame seals tightly against the dash adapter plate or pillar pod to prevent rear-wave sound cancellation.
• Apply Acoustic Sound Deadening: Applying small sound damping pads (such as NVX Sound Deadening) inside dash cavity voids stops thin plastic dashboard grilles and wiring harnesses from rattling.
