EMP E10s Powered Subwoofer - Bottom View

EMP E10s Powered Subwoofer - Bottom View
Robert Silva

Shown here is a photo view of the bottom of the EMP Tek E10s Powered Subwoofer.

The first thing to note about the bottom of the EMP Tek E10s are the sturdy feet that elevate the bottom of the subwoofer off the floor. The second important feature is the down-firing port. The purpose of this port is to provide further ​low-frequency bass extension for the E10s. In other words, with both the bottom port and front-facing 10-inch driver, the E10s can provide more powerful deep bass response than its compact size would indicate.​​​

EMP E10s Powered Subwoofer - Rear View - Controls

EMP E10s Powered Subwoofer - Rear View - Controls
Robert Silva

Here is a close-up look at the adjustment controls for the E10s Powered Subwoofer. The controls are as follows:

Volume: This is also commonly referred to as Gain. This is used to set the volume of the subwoofer in relation to the other speakers.

Crossover: The crossover control sets the point at which you want the subwoofer to produce low-frequency sounds, against the ability of the satellite speakers to reproduce low-frequency sounds. This control is defeatable if using the subwoofer crossover control on a Receiver. The crossover adjustment is variable from 50 to 150Hz.

Phase Switch: This control matches the in/out subwoofer driver motion to the satellite speakers. This control has two positions 0 or 180 degrees.

EMP E10s Powered Subwoofer - Rear View - Connections

EMP E10s Powered Subwoofer - Rear View - Connections
Robert Silva

Shown on this page are the input/output connections available on the E10s Powered Subwoofer.m Beginning on the top and moving down this photo are the Input/Output connections, which include an LFE line level RCA input, 2 line level/RCA phono jacks (1in/1out), and 1 set of standard speaker input/output terminals.

This subwoofer can be connected in three ways. The easiest way is to connect the subwoofer line output from a home theater receiver to the LFE line input (yellow) on the E10s.

Another option is to connect to the subwoofer using the L/R stereo (red/white) RCA audio input connections.

The final connection option on the E10s includes using left/right speaker connections (labeled as high-level connections) from receivers or amplifiers that do not have a dedicated subwoofer line output. In this type of setup, the subwoofer accepts the entire signal that goes to the main left and right channel speakers, but only utilizes the low frequencies for itself and passes the remaining frequencies to main speakers via traditional speaker output connections.

Final Take on the EMP HTP-551 5.1 Channel Home Theater Speaker Package

I found that the EMP Home Theater Speaker System delivered clear sound across a wide range of frequencies and well-balanced surround sound image.

The EF50C center channel speaker sounded good, but its diminutive size seemed to contribute to a lack of strong impact on some vocals and dialog. However, that being said, the EF50C does integrate well into the rest of the system. With a little center channel tweaking using a home theater receiver, the user can still get satisfying results from the EF50C.

The EF50 bookshelf speakers, which were used as both left and right mains and surrounds, performed their job well. Although very compact, they held their own in reproducing both front and surround and balanced well with both the EF50C center speaker and the ES10 subwoofer.

We found the ES10 powered subwoofer to be a good match for the rest of the speakers. Despite its compact size, it provided a good low-frequency transition from the mid-range and high-frequency response of the EF50C and EF50.

Although I wouldn't consider the EMPs a true audiophile speaker system, EMP has delivered an affordable, good quality, system for a more mainstream user. I give the EMP Tek 5.1 Home Theater Speaker System a solid 4 out of 5 Star Rating.
