Our selection of Speaker Drivers here are all the classic conical type, although other types such as speaker tweeters and horns are also available in our store. The replacement woofers are built to accentuate the low end of your music, providing a way to hear bass frequencies clearer. You'll also find a selection of replacement midrange speakers (most known as "drivers") designed for the augmentation and customisation of existing PA speakers or similar.

Buy Speaker Drivers

Drivers are essential to a speaker, it is through the driver that any sound can effectively reach your ears, thus sometimes customers do not need a brand new speaker but merely only need a set of replacement woofers. This is where our range of replacement midrange speakers/drivers come in handy for those looking to revitalise or upgrade their existing speaker system. There is not a driver currently in existence which can comfortably handle a full range of frequencies all alone which is why woofers, midrange drivers and tweeters all have an important job to do.

Tweeters deal with the high-end frequencies above 2000 Hertz (Hz) in your music or more specifically the treble in your mix and will accentuate instruments such as strings, piano or upper octave keyboard notes. Midrange frequencies are anything between 200Hz and 2000Hz and will bring forth sounds such as guitars or tom drums and your bass is anything below 200Hz which of course works the bottom end of the range. Speakers that have multiple drivers built within are called full-range speakers and use multiple drivers to achieve a wider spectrum of audio output.

Replacement woofers

Both woofers and replacement midrange drivers remain some of our best-selling items as music lovers get the very most from their speaker cabinets. The drivers can also be used in car sound systems to boost your listening experience when on the move, with multiple sizes to suit the spacial capacity of most modern four-wheel vehicles. Those in need of a replacement woofer should consider calling our customer service team, if in need of advice.

Once installed the electromagnets inside the speaker cabinet prompt the materials used in the driver to move forward and backwards at speed. This motion then triggers a similar effect within your ears, resulting in the heard sound, there are multiple different materials drivers are made from and each one will sound slightly different, though this difference is negligible to the untrained ear. Drivers are an imperative part of your speaker setup, be sure to do some light research before purchasing a component of any type to ensure it will fit comfortably with the rest of your gear.

Frequently Asked Questions

What is a speaker driver?

A speaker driver is a component within a loudspeaker that converts electrical energy into sound. Drivers come in various types, each designed to handle specific ranges of frequencies: woofers for low frequencies (bass), tweeters for high frequencies (treble), and mid-range drivers for frequencies in between. The performance and quality of a speaker largely depend on the design, materials, and construction of its drivers.

Are speaker drivers different sizes?

Speaker drivers vary in size to suit different sound frequencies. Large drivers, or woofers, handle low frequencies and can be 8 inches to 15 inches or more in diameter, producing deeper bass by moving more air. Small drivers, or tweeters, designed for high frequencies, range from 0.5 inches to 1.5 inches, allowing for quick movement to accurately reproduce high sounds. Mid-range drivers fall between these sizes, handling the frequencies in between.

What does a conical driver mean?

A conical driver refers to a speaker driver that uses a cone-shaped diaphragm to produce sound. This cone, typically made from materials like paper, plastic, or metal, moves in and out to push air and create sound waves. The conical shape is efficient at converting energy into sound across a wide range of frequencies and is common in many types of speakers. This shape helps in evenly distributing sound waves, contributing to the driver's ability to deliver clear and dynamic audio.

Can I fit a replacement speaker driver myself?

You can fit a replacement speaker driver yourself with some basic tools and careful instruction following. First, ensure the replacement matches your speaker's specifications like size, impedance, and power handling. Gently open the speaker case, remove the old driver by unscrewing and detaching its wires, then connect and secure the new driver, paying attention to the positive and negative wire terminals. Test the new driver before fully reassembling the speaker to confirm it works properly.

Why would I need a replacement speaker driver?

You might need a replacement speaker driver due to wear and tear, damage from impacts or moisture, or overdriving that leads to distorted sound. Additionally, you may want to upgrade for better sound quality, efficiency, or power handling. DIY enthusiasts also replace drivers to customise the sound profile of their systems. Essentially, replacing a driver can extend the life of your speaker or achieve a specific audio quality.

What is the difference between a subwoofer and a midrange driver?

A subwoofer and a midrange driver are designed to handle different parts of the sound spectrum in a speaker system. A subwoofer reproduces very low frequencies, typically below 100 Hz, focusing on deep bass sounds. It's larger in size to move more air, producing the physical sensation of bass. A midrange driver targets the middle portion of the audio spectrum, roughly from 250 Hz to 2,000 Hz, where most vocals, guitars, and other instruments fall.

Are all speaker drivers the same?

No, all speaker drivers are not the same. They vary significantly in design, size, and material, each tailored to reproduce different parts of the audio spectrum with accuracy. There are several types, including woofers for low frequencies (bass), tweeters for high frequencies (treble), and mid-range drivers for frequencies in between. Subwoofers are designed specifically for very low bass frequencies. Additionally, the materials used in drivers, such as paper, plastic, or metal, and their construction (e.g., cone shape, magnet size) also differ, affecting sound quality, durability, and performance.

Will any driver work in my speaker?

No, not any driver will work in your speaker. For a replacement driver to be compatible, it must match the original in size, impedance, power handling, frequency response, and sensitivity. These specifications ensure the driver fits properly, can handle the amplifier's power, and reproduces the intended range of sounds accurately. Using the wrong driver can result in poor sound quality, damage to the speaker, or failure of the system. It's important to select a replacement driver carefully to maintain the performance and balance of your speaker system.
