Model: SB-F1 Linear Phase Speaker System

The Technics SB-F1 is a 2-way, 2-speaker sealed enclosure bookshelf speaker originally released in 1978, known for its advanced design for its time. It features a 10 cm cone woofer and a high dome tweeter with exponential loading, mounted behind the woofer for phase correction.
The speaker has a nominal impedance of 8 Ohms and a sensitivity of 86 dB/W/m, with a frequency response ranging from 50 Hz to 20 kHz (-16 dB).
It is designed to handle up to 60 watts of music input and 40 watts of DIN input.
The cabinet is constructed from die-cast aluminum, contributing to its high rigidity and low resonance.
The speaker includes a linear phase design to align the sound center with the woofer, and it uses a 4 kHz crossover frequency.
Optional accessories include the SH-S1 tripod stand and SH-S2 speaker angle brackets.
The SB-F1 was available in silver and black finishes, with some rare versions, like the HAN-T1, featuring a built-in quartz clock and a transparent plastic grille.
The speaker's design incorporates high-quality components such as an aluminum voice coil, polyamide adhesive for heat resistance, and a magnetic circuit with a 10,000 Gauss flux density.
Despite its small size, the SB-F1 is praised for its detailed and crisp sound, good imaging, and a surprisingly large soundstage for its dimensions.
However, users note it lacks deep bass, making a subwoofer a recommended addition for fuller low-end response.
The speaker's weight each is 2.3 kg, and its dimensions are 11.8 x 21 x 12.6 cm.
