JTR Speakers Reveals Its New Captivator 4000ULF-lp Subwoofer
(JTR Speakers)(October 3, 2017) JTR Speakers has officially welcomed a new subwoofer model to its family of highly respected subsonic machines. The new Captivator 4000ULF-lp ($3499; $3149 pre-order) introduces a new design twist to the company’s legendary and hard-hitting Captivator 4000ULF sub.
ULF stands for “Ultra Low Frequency,” which is exactly where both the Captivator 4000ULF and 4000ULF-lp are more than capable of operating. Much like the original design, the 4000ULF-lp features a cabinet tuned to 10Hz. Relying on the same 18” drivers (33 xmax each way, +4” peak to peak) and built-in 4000-Watt RMS DSP optimized Class D amp, JTR has moved the drivers and slot ports to the wide side of the cabinet, allowing the sub to be built into baffle walls and false walls.
The addition of “lp” in the model number signifies “low profile.”
Otherwise, JTR’s Jeff Permanian says the two models perform exactly the same. That is to say, they are capable of nail popping and foundation shifting performance.
“The Captivator 4000ULF is among the most powerful subwoofers ever tested by Data-Bass,” explains Permanian. “In fact, it’s the loudest ever tested at 10hz.”
Indeed, Data-Bass has yet to test a sub capable of outperforming the 4000ULF design at 10 Hz, leading the site to remark that the design is “one of the most powerful subs that has come across [our] test bench and should be an excellent option for those on the market for an uber sub or two for a large dedicated space.”
(JTR Speakers)Weighing a backbreaking 265-pounds and standing over three feet tall (41″ H x 39.5″ W x 20.5" D), the Captivator 4000ULF-lp is a gorgeous heavy hitter. Much like other JTR designs, it features an 18mm, 13 ply, void free Baltic Birch cabinet, complete with extensive internal bracing and a magnetically attached grille. The cabinet is offered in a standard matte black finish, however premium custom finishes are available upon request.
AV NIRVANA recently launched two new Official JTR Speakers threads (one for the company’s speakers, the other for subwoofers), and we invite both owners and fans of the brand to join the conversation!
