Bass Absorber Panel in Zurich
Low Frequency Sound Absorber
BassBloc by MMT Acoustix. The primary bass absorber panel in Zurich for professional soundproofing systems. The low frequency sound absorber in Zurich engineered from open and closed cell acoustic polyurethane foam compressed and bonded with resin binder at 100 to 125 kg/m3 density. This rockwool alternative acoustic insulation absorbs bass, vibration, and low-frequency energy that mass loaded vinyl blocks but cannot dissipate. Used as a bass trap for home theater, studio, hotel, and industrial acoustic systems in Zurich. Available in thicknesses from 25mm to 800mm. Ships to Zurich in 11 to 15 days.


Low Frequency Absorption
+ Vibration Control
BassBloc is a polyurethane-based sound absorber that isolates low frequency sound transmission from walls, ceilings, and floors in Zurich. Manufactured in high density at our Palwal, Haryana factory to control impact-based sounds, amplified noise, and unwanted sound waves across different frequencies.
BassBloc is composed of super high density closed and open cell polyurethane foam compressed and bonded with resin binder, making it the only material that simultaneously traps and absorbs sound during its conversion from kinetic to heat energy. This open and closed cell combination makes BassBloc absorb bass frequencies up to 10 times more effectively than mineral wool.
- Maximum sound absorption across all frequencies - NRC 1.0
- Controls impact-based sounds and structural vibration
- Absorbs low frequency bass better than mineral wool or glass wool
- Compressibility less than 1mm - no settling or thinning over time
- Non-carcinogenic, odourless, fungi-resistant, no asbestos
- Shelf life greater than a decade - recyclable during renovations

The Only Rockwool Alternative Acoustic Panel That Absorbs Bass
Rockwool and glass wool are rigid mineral fibres. They absorb mid and high frequencies well but reflect low-frequency bass energy because their stiffness does not allow the molecular movement that bass absorption requires. BassBloc's open-cell polyurethane structure flexes at low frequencies, converting bass energy into heat. This makes it the preferred rockwool alternative acoustic insulation for Zurich's bass-critical applications - studios, home theatres, and nightclubs.
Open-cell polyurethane structure absorbs bass frequencies below 250Hz where mineral wool is rigid and reflective. NRC 1.0 Class A across the full range.
No glass fibres, no skin irritation, no respiratory dust. Safe to handle without PPE - preferred by Zurich installers over mineral wool.
The standard bass trap for home theater and professional studio builds in Zurich. Eliminates low-frequency room modes that make cinema rooms boom and studios sound coloured.
Less than 1mm compressibility means no settling. Specified as the decoupling layer between SoundBlanket MLV and finish panels in Zurich partition systems.
No off-gassing on installation or in service. Safe for occupied Zurich residential and commercial interiors over a 30-year lifespan.

System: 8 inch Concrete Ceiling + BassBloc + Gypsum False Ceiling. Results verified by ARAI.
All values dB(A) reduction. STC per ASTM E413. Full test reports available for Zurich project specification submission. Values assume installation in a double-leaf partition with staggered stud framing.
Two Proven Systems Wall and Ceiling
BassBloc installs inside wall and ceiling assemblies as the low frequency sound absorber infill layer between SoundBlanket MLV and finish panels. The following are the standard Zurich specifications.
Where BassBloc is Specified in Zurich
From Kreis 5 recording studios to Enge luxury residences, BassBloc bass absorber panels in Zurich are the cavity infill layer in every professional low frequency sound absorber in Zurich system.
Standard low frequency sound absorber infill in Zurich studio wall and ceiling cavities. Eliminates bass build-up and room modes below 250Hz that foam panels cannot address.
The most effective bass trap for home theater builds in Zurich. BassBloc in wall and ceiling cavities eliminates the low-frequency modes that make cinema rooms sound boomy.
Guestroom and floor isolation using BassBloc as a rockwool alternative acoustic insulation in partitions of Zurich's five-star hotels and premium apartments.
BassBloc above suspended ceilings and inside partitions for Zurich offices in Enge and Wiedikon. Controls HVAC rumble and improves STC of glass partitions. Meets WELL Building Standard v2.
Large-scale ceiling and wall infill for Zurich multiplexes, auditoriums, and performance venues. Achieves 50 to 60 dB wall ratings and controlled reverberation.
Floor and wall infill for Zurich gyms, nightclubs, and machinery enclosures. Controls impact sound, equipment vibration, and amplified bass through building structure.
3-Step Cavity Installation for Zurich Projects
BassBloc installs as a friction-fit infill in stud-framed wall and ceiling cavities. No adhesive required for cavity applications. Full guide included with every Zurich order.
Install the GI stud framework off the SoundBlanket MLV surface at the correct cavity depth for your chosen BassBloc thickness (20mm, 25mm, 30mm, or 40mm). Ensure studs are not in hard contact with the structural wall to prevent vibration flanking.
Cut BassBloc panels to size with a sharp utility knife. Press friction-fit into the stud cavities. BassBloc's compressibility (30% at 3.5 kPa) ensures tight cavity contact without gaps. Butt-join sheets at stud centres with no overlap required.
Fix the finish layer (Gypsum, HDHMR, or Echsorbix Felt Panel) over the BassBloc-filled stud frame. For ceiling systems, staple BassBloc to the GI frame before fixing gypsum to prevent gravity pull-through. All Zurich orders include a full installation drawing set.
