Dayton Audio HTS545HE-4 Kraken 21″ High Excursion Subwoofer with 5″ Voice Coil 4 Ohm
It takes a monster to deliver serious bass response
You need to move a lot of air for high SPL and deep bass response, and Dayton Audio’s HTS545HE-4 21″ Kraken home theater subwoofer driver can beat most high output subwoofers in the industry. This massive driver is capable of 21 mm of excursion in each direction (@ 70% BL, Klippel verified) giving it the ability to move over 7 liters of displacement with each stroke. Displacement isn’t all you need for maximum output; power handling and efficiency are also necessary. Capable of handling 2,000 watts RMS and with over 95 dB sensitivity, the HTS545HE-4 has what it takes to deliver ultra-low frequency response with authority. Dayton Audio has released the Kraken to bring you true high output, low frequency bliss.
Know when to say when with Over-Excursion Protection
Although the Dayton Audio HTS545HE-4 21″ is designed to produce incredibly low frequencies at phenomenal output for extended periods of time, we understand that subwoofers are frequently driven up to and beyond their published limits and we expect that this driver will be no exception. All too often subwoofers fail prematurely due to being over driven, so to minimize this from happening and to extend its life Dayton Audio implemented an OEP (Over-Excursion Protection) system which audibly alerts the user just before catastrophic failure occurs. The Dayton Audio’s HTS545HE-4 is purposely built to provide years of the powerful bass you crave.
Extreme power, but also control and accuracy
Powering the Dayton Audio HTS545HE-4 is an advanced high energy double stacked ferrite motor assembly. Unlike neodymium magnets, the powerful ferrite magnets are capable of delivering a constant motor force even when exposed to high heat to keep power compression at a minimum. Its 5″ inside/outside wound voice coil uses a fiberglass former that can withstand extreme temperatures to handle up to 2,000 watts RMS without issue. A large pole piece vent, 6 peripheral gap vents, and numerous vents between the frame and top plate allow plenty of air to move across the voice coil, further reducing power compression caused by increased resistance due to heat. To keep distortion to a minimum at high output, the pole piece also includes a large aluminum shorting sleeve. All of this gives the HTS545HE-4 the ability to deliver predictable and consistent low frequency output even when driven to extreme SPL levels for extended periods. In addition, most high excursion subwoofer drivers suffer from lower midbass response and tend to lack impact and punch, the HTS545HE-4 has the motor strength to produce unbelievable midband efficiency, control, and output which eliminates the need for additional midbass systems in large home theaters.
Built to last a lifetime
Dayton Audio built the HTS545HE-4 to take the continuous output necessary to accurately reproduce today’s demanding movie soundtracks. The naturally damped treated paper cone is optimized and reinforced to handle the stress of exceptionally high excursion while maintaining its shape. To keep the cone under control, the HTS545HE-4 uses dual large diameter spiders with ample spacing to provide extreme linearity. A huge SBR foam surround is double stitched to the cone to allow for incredible linear excursion, even when driven to its limits and beyond. Holding everything together is a rugged cast aluminum frame that will not restrict airflow, and includes integrated push button wire terminals for a reliable and secure electrical connection. The HTS545HE-4 has been built to deliver years of worry-free performance.
Beware the power and impact of the Kraken
If you’re looking for one of the highest output ultra-low frequency drivers in the industry, the Dayton Audio HTS545HE-4 is an unbeatable value. This versatile driver is a great choice for vented designs, back loaded horns, and even tapped horns. With a 4 ohm voice coil this driver is also perfect for use in dual and quad driver systems for the ultimate in extended low frequency output capability. A true monster of a driver, Dayton Audio’s Kraken comes from the abyss to take you down into the depths.
Note: Please be sure to secure everything in your house before you release the Kraken.
