JBL Ti6K (1999)
The JBL Ti6K is a floor-standing, 3-way, 4-speaker bass-reflex system released in 1999, part of JBL's high-end Ti series. The enclosure is curved and rounded with no parallel surfaces, which is meant to eliminate internal standing waves and cabinet resonance. The front baffle is 25 mm MDF. The curved side panels are built from six layers of MDF plus two plate layers. The whole thing sits on 3-point pinpoint cleats. It was offered in a beech wood grain finish or semi-gloss black.
The driver complement is where the "Ti" name comes from. The high range uses a 2.5 cm pure titanium dome tweeter (Ti025K) with an aluminum voice coil, and it extends response beyond 30 kHz. The midrange is a 10 cm inverted titanium dome (804 ti) with a 37 mm voice coil and a neodymium magnet, and it is magnetically shielded. For the lows, two 16.5 cm polypropylene-cone woofers (806J) use an SFG magnetic circuit, an edgewise-wound flat wire voice coil and an aluminum die-cast frame.
Known specifications are as follows:
- Frequency response: 38 Hz – 30 kHz
- Output sound pressure level: 90 dB / 2.83V / m
- Impedance: 6 Ω
- Allowable input: 150W (IEC)
- Dimensions (W x H x D): 380 x 1,100 x 530 mm
- Weight: 36.0 kg
The Ti6K has a strong reputation among collectors. It's often described as one of the top ten speakers JBL ever built, and long-discontinued examples are highly sought after. The Ti series also included the larger Ti10K, which used a double woofer structure for higher output and deeper bass, and the smaller Ti2K, which needed a stand rather than the Ti6K's spikes. Period forum commentary says the Ti6K is a bit more forward in presentation than the Ti10K. Its bass, while good, isn't the deepest, which comes from the two 6.5-inch woofers. The record on this model is otherwise thin. No detailed period magazine reviews have surfaced, and much of what's known comes from Japanese audio databases and enthusiast forums.
