Полочная акустика — ToneWinner TD-3

Guangzhou Tonewinner Electronics, a Chinese manufacturer based in the Panyu District of Guangzhou, produces the TD-3, a passive compact monitor that splits the band between two drive units. It sits in the Hi-Fi series of the company catalogue and pairs a small dome tweeter with a Kevlar mid-bass unit in an unusually heavy cabinet built from thick fibreboard with a rosewood veneer finish and a black metal front panel.

Key specs that matter

Tonewinner lists a frequency response of 40 Hz to 25 kHz and a harmonic frequency of 40 Hz with a 20 percent tolerance. Rated impedance is 8 ohm and sensitivity is 85 dB with a tolerance of 3 dB. The recommended amplifier power runs from 10 to 100 W. Each cabinet measures 230 x 360 x 405 mm and weighs 13.5 kg net, while a boxed pair ships at a gross weight of 30 kg. The driver complement is one 28 mm dome tweeter above one 7 inch mid-bass unit whose cone uses Kevlar synthetic fibre.

Engineering and use context

Its front baffle is cut from 50 mm medium density fibreboard and the side walls use 25 mm panels, which accounts for the high mass of a speaker of this footprint. Low frequencies are tuned by a rear bass reflex vent that is formed as one piece with the enclosure. Inside, the crossover places metallized polypropylene film capacitors of the MKP type in the high-pass path, arranged in three levels, and uses large inductors wound from oxygen-free copper. The mid-bass unit is held by a durable rubber surround. Connection is made through dual terminals of oxygen-free copper with 24K gilding, which gives two separate connection pairs on the rear of each cabinet. The rosewood veneer is applied over the MDF shell, and the black metal front plate frames both drive units. Tonewinner lists the TD-3 under its Hi-Fi speaker series next to its multi-channel and home cinema products.

Pairing

Given the modest sensitivity, a capable amplifier suits the TD-3 better than a small low-power one. Tonewinner itself proposes a complete system built around the TD-3 with its AD-3PRO integrated amplifier and the TY-50 CD player, which keeps the whole chain within one brand. The dual gilded terminals also allow two amplifier channels per speaker for owners who want to split the tweeter and mid-bass feeds.

Alternatives

Within the same Tonewinner Hi-Fi speaker range, the TD-7SE is a smaller passive two-way bookshelf model with a silk dome tweeter and a 6.5 inch paper cone mid-bass unit.
