Dayton Audio's Titanic series subwoofers are world-renowned for their ability to create deep, hard-hitting bass with minimum distortion. This line of subwoofers has always been known for prodigious amounts of Xmax, relatively high sensitivity specifications, and an amazing ability to handle power.
Dayton Audio takes everything that has made the Titanic subwoofers stand out as top-of-the-line subwoofers in the loudspeaker industry and improves upon them in the Mk 4 generation. The TS400D-4 15" Titanic Mk 4 subwoofer has been redesigned from the ground up to improve upon every aspect possible, while maintaining the essence of the Dayton Audio Titanic series.
It All Starts with the Motor
The re-tooled motor focuses even more magnetic flux in the gap, for a lower Qes and Qts. This allows for the same performance as a Titanic Mk III 15", in a much smaller box. Where the Mk III needed at least 2.44 cubic feet of net internal airspace for a Qtc alignment of 0.707 and an f3 of 43 Hz, the Mk 4 needs 1.67 cubic feet of internal airspace for the same Qtc alignment and f3 (when used with two pounds of Acousta-Stuf fill).
The Titanic Mk 4 has two additional millimeters of physical Xmax (where the Mk III Titanic's listed Xmax is based upon DUMAX measurements, the Mk III's physical Xmax is 16 mm). A Titanic Mk 4 will also play lower than a Titanic Mk III due to a 22% lower free air resonance. This translates into more output, down low, where you want it in home theater.
This American-made subwoofer has the muscle you need to pressurize your home or mobile audio system with deep, clear, clean bass. Check the structural integrity of your house, or car, before applying power!
And Everything that Made the Titanic Subwoofers Famous
Dayton Audio's TS400D-4 Titanic Mark 4 subwoofer is built with a sturdy aluminum die-cast frame to keep everything perfectly aligned while handling the insane amounts of air pressure it's capable of generating inside of a sealed enclosure. An extended pole piece keeps more of the voice coil in the gap for more motor control.
Frame openings under the spider help to reduce power compression (and trapped air) and the vented pole piece keeps the edgewound voice coil cool, for high power handling. The Kevlar-reinforced paper cone resists deformation under excursion, and the large rubber surround keeps cone travel linear. For a tight seal on the baffle, an integrated rubber gasket is pre-mounted to the frame.
