Adjustable Crossover Point Volume Adjustable Crossover for HIFI Horn Super Treble Unit Full Range Speaker

Adjustable Crossover Point Volume Adjustable Crossover for HIFI Horn Super Treble Unit Full Range Speaker

This is an ideal four stages adjustable crossover/6-segment level-adjustable supersonic crossover. The level uses a precision resistor to form an L-shaped attenuation line, which ensures impedance stability. The frequency division parameters are as stable and reliable as textbooks, and crossover level is adjustable in six stages. It can be connected to any 8 ohm super treble unit, even if it is high sensitivity super treble unit, it can be attenuated to a reasonable level. Choose to use step switching to ensure that its balance is left and right at all times.

 

In particular, it is important to note that the sensitivity of super treble unit is preferably about 5 dB higher than the matching speaker to complement the speaker!

If the super treble unit is 4 ohms, a 3.9 ohm 5 watt non-inductive resistor can be connected in series, and then connected to the adjustable crossover, it can have the same effect.

IWISTAO Discrete Components MM/MC Phono Stage FET Amplifier for LP Phono

IWISTAO Discrete Components MM/MC Phono Stage FET Amplifier for LP Phono Split-type AC110V/220V HIFI Audio

The phono preamp contains two types of phono amplifiers, MM and MC, which can be adapted to most users' vinyl record players on the market.

Choose fully discrete components to build the circuit, easy to fine-tune the various data parameters.

The main amplifier circuit adopt Field Effect Transistor (FET), which is convenient to reduce the sensitivity of the components to temperature changes and improve the distortion.

Choose pure class A circuit to form discrete component amplifier circuit, effectively reduce harmonic distortion and improve sound effect.

The phono equalization circuit does not use the feedback circuit of the conventional integrated IC circuit, but chooses the attenuation type, whichever is the natural characteristic of the timbre.

The two aluminum chassis are the same size, both are 133mm wide, 63mm high, and 250mm deep.

IWISTAO HIFI Speaker Full Range Cabinet 4 Inches Unit 4 Ohm 15~60W 94dB Solid Wood Enclosure Desktop 1 Pair Inverted Structure

The speaker unit is selected from HIFI 4 inch full-range speaker unit, high sensitivity and wide sound range. 

It adopts composite paper cone for the basin body, double folded side suspension structure, strong neodymium

magnet as its magnet, and a voice coil with a diameter of 26mm.

Listening to this speaker, its performance in each frequency band is considered to be balance, vocals are clear and the

lips and teeth are distinct. It can be said that whoever you listen to has a distinct taste.

Its high-frequency part can express most of details, and will never let you miss the reverberation of triangle iron,

piccolo, etc. It is commendable for its low-frequency performance, which can be described by the word "dive", which makes people suspect that it is only a 4-inch unit.

After auditioning for vocals, strings, symphony, and pop, then chose the dust drum. This drum beat percussion, under such a dense, high-energy drum beat, the speaker can handle it with ease, the speed is extremely fast, and there is no delay.
