BLAM Audio - Buy the 'French Sound' at a great price in the Masori car audio online shop
Anyone looking for an expressive car hi-fi solution in their vehicle will inevitably come across BLAM Audio. This French manufacturer focuses specifically on midrange tuning to reproduce vocals with vividness and detail. In addition to compact coaxial and high-quality component systems, the portfolio also includes versatile subwoofers and powerful amplifiers. A particular feature is the "French Sound", characterized by a warm, wide and dynamic tonal character. BLAM Audio impresses with different product lines for every budget and offers tailored solutions for VW, BMW, Mercedes, SEAT or Opel.
Coaxial speakers and full-range drivers – BLAM product lines in detail
When it comes to car hi-fi, coaxial speakers play a central role. BLAM Audio serves this area with series like RX or RC, which offer numerous features:
-
RX series: Entry-level with 165 mm woofer, integrated crossover, 20 mm soft-dome tweeter and 4 Ohm impedance. Frequency range between 60 Hz and 20 kHz.
-
RC series: Higher-end coaxial system with 50 Hz to 21 kHz, sometimes 2 Ohm impedance for higher amplifier loading, usually 130 W maximum power handling.
An absolute highlight is the model Blam 165 RC System from the RELAX line. It combines two 165 mm woofers and one coaxially mounted high-frequency driver each, creating a very coherent sound image. The 2-Ohm variant radiates louder at the same amplifier power, which is particularly popular in the car sound segment.
BLAM Audio also scores with full-range drivers like the Blam LM80. This speaker covers 100 Hz to 25 kHz and, with 3 Ohm impedance, brings more power into the vehicle. Those seeking mid-range car sound upgrades will find an uncomplicated plug-and-play solution with this model.
Key features of BLAM Audio product ranges
-
RC series: Balanced sound with silky smooth highs thanks to the 20 mm soft-dome tweeter.
-
EC series: Efficient coaxial system with 2 Ohm impedance, high sound pressure levels with low amplifier load.
-
Multix series: Competition-level with 30 Hz to 28 kHz, 4 Ohm impedance and often 200 W maximum power handling.
-
WS series: High-end ambition with extended frequency range from 40 Hz to 25 kHz, 3 Ohm impedance and increased power handling typically around 150 W.

Subwoofers and amplifiers – powerful complements to car sound
To complete the sound image in the car, BLAM Audio also offers subwoofers in various sizes from 8 to 12 inches. These are usually housed in compact enclosures and deliver deep bass reproduction down to 30 Hz. Amplifiers round out the setup:
-
Mono amplifiers: High damping factor, stable 2-Ohm operation and up to 1000 W RMS for punchy low-frequency support.
-
Multi-channel amplifiers: 4-channel to 6-channel for system setups with front, rear and subwoofer control. Compact Class-D technology, very high efficiencies.
Integration into vehicles like the VW Passat, BMW 3 Series or Opel Astra is often simplified by plug-and-play connectors. This eliminates complex wiring and allows installation to be completed within a few hours.
All important tips for installation, accessories and service
Anyone who wants to install BLAM speakers in their car should pay attention to a clean acoustic environment. In addition to the speakers themselves, using various accessories is recommended:
-
Mounting rings: Allow flush fitting in the door frame or dash.
-
Wiring kits: High-quality OFC copper cables (Oxygen Free Copper) improve signal quality and prevent voltage drops.
-
Damping materials: Alubutyl mats or foam inserts reduce vibrations and distortion-related losses.
The actual installation typically includes the following steps:
- Removing the door panel and locating the original mounting points.
- Attaching the mounting rings and damping materials.
- Installing the BLAM speakers and connecting the crossovers.
- Tuning the system via the amplifier (gain, lowpass/highpass, equalizer).
- Reattaching the panels and listening tests with reference music.
If you get stuck during installation or prefer a professional installation option, you can use our Installation service in Frankfurt Oder. There BLAM Audio systems can be perfectly tailored to your vehicle's conditions. For questions about product compatibility, the Expert support from Masori as well as our AI chatbot that suggests tailored car hi-fi solutions for your model, will support you.
Performance data, variants and possible applications
Whether for a classic 2-way front system in the Mercedes C-Class or for a fully active setup in the Opel Insignia – BLAM Audio speakers can be integrated into almost any car model thanks to:
-
Different impedances: 2, 3 or 4 Ohm for optimized power distribution.
-
Multiple form factors: 100 mm, 130 mm or 165 mm diameters.
-
Different peak powers: 120 W, 150 W or 200 W.
Enthusiasts of the French sound benefit from an emphasis in the 500 Hz to 2 kHz range, which makes vocals and acoustic instruments sound particularly natural. The high-end series like WS or Multix also offer extreme excursion reserves and are designed for maximum fidelity.
Especially in vehicles that come with weaker factory speakers, BLAM systems enable a noticeable improvement in sound quality. Those who want higher maximum volume can drive the RC or EC series more intensively thanks to the 2-Ohm load. For competition applications or very wide frequency ranges, the more powerful Multix systems are suitable.
Why investing in BLAM Audio is worthwhile
The intelligent mix of solid engineering and a clear sonic profile makes BLAM Audio one of the first choices for car hi-fi enthusiasts. The targeted focus on midrange-forward vocals allows every music genre to shine, be it rock, pop or electronic. At the same time, the subwoofers deliver powerful bass impulses and blend smoothly with the midranges and tweeters. BLAM Audio stands out with these features:
- Wide series range with RX, RC, EC, WS and Multix.
- Suitable plug-and-play solutions for common brands like VW, BMW, Audi, SEAT or Opel.
- Quick installation through adaptable wiring kits and damping materials.
- Expansion options: subwoofers from 8 to 12 inches, mono to 6-channel amplifiers.
- High efficiency through variable impedances (2, 3 or 4 Ohm).
