Epos ES-28N<\/strong> is a three-way floorstanding speaker designed for a home stereo system. Two 7-inch bass drivers work alongside dedicated midrange and treble drivers, giving each part of the frequency range its own driver. The bass-reflex enclosure and low-noise port help the speaker make effective use of the lowest part of its range.<\/p>\n

Three-way speaker system<\/h2>\n

The crossover points<\/strong> are set at 330 Hz and 2,700 Hz. These divide the operating ranges of the bass, midrange and treble drivers. The crossover uses second- and fourth-order Linkwitz-Riley<\/strong> filters.<\/p>\n

The stated in-room frequency range begins below 30 Hz and extends to 25 kHz. Room size, proximity to walls and speaker positioning will affect the amount of bass heard at the listening position.<\/p>\n

Driver construction<\/h2>\n

The bass section uses two 7-inch drivers<\/strong>. Each one has a 36 mm voice coil and a hybrid ferrite and neodymium magnet system. Their straight-profile cones are injection-moulded and filled with mica. Low-hysteresis rubber surrounds are used.<\/p>\n

The 130 mm midrange driver<\/strong> has a 30 mm voice coil and a double ferrite magnet. Its polypropylene cone is also filled with mica and uses a low-hysteresis rubber surround.<\/p>\n

The 28 mm tweeter<\/strong> has an aluminium and ceramic composite dome. Ferrofluid is not used in its construction.<\/p>\n

Cabinet and placement<\/h2>\n

The cabinet is built with damped multilayer panels, directional bracing and a double-layer front baffle. These elements help stiffen the large floorstanding enclosure. The low-noise bass-reflex port is designed to reduce unwanted airflow noise.<\/p>\n

The speaker measures 1,050 \u00d7 250 \u00d7 360 mm<\/strong>. Before installation, allow for the cabinet’s 360 mm depth and leave sufficient free space around the bass-reflex port.<\/p>\n

The stated weight is 35 kg, although the source does not specify whether this figure applies to one speaker or a pair.<\/p>\n

Connections and amplifier choice<\/h2>\n

Custom-made, low-metal-mass terminals<\/strong> accept 4 mm banana plugs.<\/p>\n

Average impedance is greater than 6 ohms, while the minimum impedance is 3.9 ohms at 16 kHz.<\/p>\n

The 86 dB sensitivity figure was measured with an input of 2.823 V at a distance of one metre. To reach higher listening levels, an amplifier will need more voltage headroom than it would with a more sensitive speaker.<\/p>\n

Finish options<\/h2>\n

Four finishes are available: walnut<\/strong>, semi-matt white, semi-matt black and jade green. The 250 mm-wide front also makes it easier to judge in advance how much space each speaker will occupy beside an equipment rack or other furniture.<\/p>\n

FAQ<\/h2>\n

What amplifier should I choose for these speakers?<\/h3>\n

Choose an amplifier that can operate reliably with a load of around 4 ohms. The 86 dB sensitivity should also be taken into account. No permissible speaker power rating is provided, so comparing wattage figures alone is not sufficient.<\/p>\n

How do I connect the speakers to an amplifier?<\/h3>\n

Use speaker cable terminated with 4 mm banana plugs. Keep the positive and negative conductor polarity consistent on both channels.<\/p>\n

What is a good starting position for the speakers?<\/h3>\n

Begin with a symmetrical arrangement and place both speakers at an equal distance from the listening position. Leave clear space around the bass-reflex port. Adjust the distance from the walls according to the resulting bass balance.<\/p>\n

What does a frequency range extending below 30 Hz mean?<\/h3>\n

This lower limit is specified for in-room conditions. The audible result will depend on the room, speaker position and distance from the walls.<\/p>\n

How should I interpret distortion of less than 0.2%?<\/h3>\n

This average THD figure applies at a level of 86 dB and across the range from 100 Hz to 10 kHz. It does not describe distortion outside those measurement limits.<\/p>\n","protected":false},"excerpt":{"rendered":"
