This information is easily found on any spec sheet if you’ve bought your products, or available online if you’ve misplaced your original documentation. By checking the specs of your amp and speakers, you can find out whether they’re compatible. Amplifiers usually operate best and are rated within a specified range, like between 6 and 12 ohms. Speakers, for their part, typically have ohm ratings of between 4 and 8. We’ll be using impedance to determine the compatibility between your amplifier and speakers. For those with experience in electronics, you’ll understand precisely what resistance is, but for our (somewhat simplified) purposes it’s not vital to have in-depth knowledge. Resistance will often be represented by the Ω symbol, like 10Ω. You’ll find impedance on the spec sheets for both specs and amplifiers, but what is it? Put simply, it can be thought of as a measure of the electrical resistance of your components, measured in ohms. We’ll kick things off with ‘impedance’ ‘Impedance’ The three terms we’ll be tackling in this article are impedance, power and sensitivity. We’re talking about the essential terms used in speaker and amplifier specifications which will prove critical to your search for awesome, long-term HiFi sound. Key to ensuring effective synergy between your speakers and your amplifier is having a basic grasp of HiFi vocabulary. So, for your devoted audiophiles, let that serve as a warning! Understanding speaker and amplifier matching terminology But for most people, they’re simply too difficult to get an immediate grasp on – especially for a job you won’t be doing often.Īs such, this guide is going to be something of an essentials piece, giving you all the information you need without the complicated maths or advanced terminology like slew rate, dampening or electromotive force, so you can get back to what matters – your music. Here on the internet, you’ll find dozens of extremely technical and maths-heavy explanations. Yes, though that innocuous metal box might look similar to other amplifiers in the showroom, it will produce a unique sound profile and, through its technical specifications, support some – but not all – of the speakers available to you.Īs you can imagine then, amplifier and speaker matching is quite vital, but it’s not as simple as just matching spec numbers and hitting play – it’s about complete system compatibility.īy effectively ensuring speakers and amplifier synergy, you can ensure a fuller, richer sound which won’t blow your speakers and will deliver superior performance and quality – well worth doing if you’re spending good money on your set up. This remains true despite the fact that amplifiers are almost as crucial to the tone and overall presentation of your audio as your speakers are. Though we spend countless hours scouring local HiFi suppliers and reading reviews to find the perfect speakers, often, our choice of amplifier is something of an afterthought. Well, when it comes to matching that amplifier with your speakers, the answer is quite a bit, actually. After all, they’re usually an innocuous enough looking metal box with a series of (delightfully tactile) knobs and switches, so what else is there to know, really? For the uninitiated, amplifiers can seem like they’re all much of a muchness.
