Focal E 25KX 10" Subwoofer

The super-rigid zinc alloy basket creates a stable platform for powerful, accurate bass.

Assembled and inspected by hand

You can feed the K2 Power E 25 KX 10" subwoofer up to 600 watts RMS without fear. This dual 4-ohm voice coil sub works best in sealed enclosures to produce bass that's highly accurate and plenty forceful. Focal assembles each sub by hand and rigorously inspects them for any flaws to ensure your investment performs to the high sonic standards they've set.

Powerful magnet

A massive two-segment magnet supplies the backbone for the sub's powerful reputation, driving the motor assembly with unerring precision. Focal anchors the K2 Power sub with a rugged zamak zinc alloy basket for dependable performance that won't get bent out of shape by your music.

3-layer cone

At the top end of the sub, a butyl rubber surround maintains control of the cone, even during deep excursion. Focal's unique composite sandwich cone employs a structural foam central core coated with a layer of Aramid fiber on the front and a glass layer on the back side. The three layers together form an incredibly rigid yet lightweight membrane for high-quality sound reproduction with an added emphasis on thunderous sound pressure.

To drive this single subwoofer, we recommend a mono amplifier rated between 450 and 900 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

Focal E 25 KX

Verified employee purchase (What's this?)

I bought one of these about a year ago. Put it in a .6 cubic foot 3/4 thick 1 1/2 inch thick front solid wood box (not MDF had the boards) it is driven by a JL 750HD, subsonic filter off, 315 hertz/12 slope. Beats rock and roll drums like nothing else, very punchy, Ozzy Osborne , iron man for instance. Borrowed my wife's W6 in a sealed MDF box for comparison, the W6 did not stay in my truck for more than a few hours. Focal wins the SQ hands down. Of coarse W6s are not designed for over 250 Hz. All depends on what you're looking for, great speaker, small footprint awesome sound, enough said...

Pros: SQ, response range, quality

Cons: With a focal? Really?

Product Research

Features

K2 Cone: The woofer cone is a sandwich composite consisting of a foam core, a structural glass fiber bottom layer, and a Kevlar top layer. This combination of materials results in a rigid, light weight cone with excellent damping characteristics.

Dual 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω load.

Compression Terminals: The two sets of spring post terminals will accommodate single banana plugs, dual banana plugs (standard 3/4" width), and bare speaker wire up to 10 gauge.

Sealed Box: Focal recommends sealed enclosure sizes from 0.53 ft³ to 0.78 ft³. Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable for all types of music.

Ported Box: Two ported enclosure volume options are listed in the manual; 0.78 ft³ (22 liters) with one 3.15" (8cm) diameter x 13.78" (35cm) long port and 1.06 ft³ (30 liters) with one 3.15" (8cm) diameter x 16.93" (43cm) long port. Ported (or vented) enclosures typically provide better overall efficiency than sealed, so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
Bought becuase I have the Elite series speakers in the front + back of my truck and thought this speaker would compliment that setup. [ Tony  May 02, 2018 ]
