FSL-1830R09-08

Speakers Overview

The FSL-1830R09-08 is an 18-inch subwoofer transducer manufactured by Peerless by Tymphany. It features a nominal impedance of 8 ohms and a power rating of 600 W. The driver has a resonance frequency (Fs) of 33 Hz and a sensitivity of 94.6 dB at 2.83V/1m. Key technical specifications include a Qts of 0.58, a voice coil size of 75.7 mm, and a DC resistance (Re) of 6.8 ohms. The transducer utilizes a ferrite magnet system and is designed for high-power low-frequency reproduction.

Speakers Feature Summary

• High-power handling capability rated at 600 W for robust performance
• Large 18-inch diaphragm diameter for extended low-frequency response
• Ferrite magnet structure providing efficient magnetic flux generation
• Optimized Qts value of 0.58 suitable for sealed or vented enclosure designs

Speakers Applications

• Professional audio subwoofer systems
• High-output public address installations
• Home theater bass management units
• Custom automotive audio low-frequency modules

Speakers Procurement Notes

Verify the specific datasheet version before ordering, as manufacturer specifications may undergo revisions. Confirm that the 600 W power rating aligns with your amplifier's continuous output capabilities to prevent thermal damage. Ensure enclosure designs account for the 75.7 mm voice coil dimensions and required air volume. Cross-reference the 8-ohm impedance with system crossover networks to maintain proper load matching.

Speakers Selection Notes

Select this model when deep bass extension down to 33 Hz is required alongside high dynamic headroom. The 8-ohm configuration allows for flexible wiring options in multi-driver arrays compared to lower impedance alternatives. Consider the physical size constraints, as the 18-inch form factor demands substantial cabinet space. Evaluate the 94.6 dB sensitivity against amplifier power availability to achieve target sound pressure levels efficiently.

Speakers Part Context

This component belongs to the Peerless FSL series, which focuses on large-format subwoofer drivers. The series is engineered for applications demanding high excursion and thermal stability. Peerless by Tymphany integrates these transducers into broader audio ecosystem solutions, often pairing them with tweeters and mid-range drivers for complete speaker system architectures.

Speakers Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific variant. When replacing, match the 8-ohm impedance, 18-inch diameter, and 600 W power rating. Verify that the new driver's Fs and Qts values fall within acceptable tolerances to preserve the original acoustic tuning.
