200W Active Speaker with Built-In Amplifier and Input Section

Product Information

Your local drive-in DJ, the next-door neighbour or even your best friend bragging about their new sound system might sound familiar to you. There are plenty of times when I’ve heard them say: “My new speakers are off the charts man, they’ve got 1,500 Watts of power!” This goes to show that a lot of people assume that more power means more volume, but really, it’s not that simple. Sure, a 1,500 Watt speaker is louder than a 10-Watt model but definitely not 150 times as loud. As a matter of fact, sometimes a 1,000 Watt speaker can produce more volume than a 1,200 Watt one. This blog is written to separate the facts from fiction and show you how it really works when it comes to the power capacity of speakers and amplifiers. Using a typical and reasonable example, we can use 16AWG stranded copper wire with 19 strands of 29AWG wire (“19/29”). Resistance per meter is rated at 0.0147Ω/m. [1] First of all, it’s important to know the difference between the giving and taking of power. An amplifier outputs power and passes it on to a speaker. In turn, the speaker takes the power and processes it. It uses the power to form a signal that’s ultimately reproduced as sound. Even though there are two different types of speakers – active ones with built-in amplifiers and passive speakers – the principle is the same: sound gets amplified. Many people don’t realise this but this is the crux of the matter. What does “100 Watts” mean exactly?

Delivering Dolby Atmos from a small chassis is no mean feat yet the Sonos Beam Gen 2 achieves a convincing, immersive performance without so much as a vertical speaker in sight. Instead, when watching Atmos content, two of the soundbar's five front-facing arrays are dedicated to reproducing overhead and surround sounds. With its hefty processing power, the Sonos Beam Gen 2 uses psychoacoustic HRTF (head-related transfer function) technology to give the impression of height without needing to get vertical. Problem: Calculate power loss for 16AWG stranded pure copper wire, 4 meters length, into a 4Ω speaker load with a maximum of 300W RMS power delivered. Determine if 16AWG stranded wire is acceptable. Say, we have a speaker with the following power handling specifications: 100 Watt RMS, 200 Watt Peak. This means the speaker needs 100 Watt to run continuously, and can handle at maximum 200 Watt’s in very short bursts. As real copper wire is more expensive these days and because most people don’t drive speakers at full power, here are some tips to keep costs down: You may have heard of the skin effect in some conductors which becomes more of an issue at higher frequencies but that’s well above the 20 to 20kHz audio range so it’s not something to worry about.

For surround sound and center channel home theater speakers, you shouldn’t spend a lot because their power needs are usually fairly low. Longer speaker runs for car & home stereo speakers or short runs under 20 ft for 75-100W. Moderate power subwoofers (under 225W) with short lengths.

It’s an easy and effective listen. No matter how hectic the action becomes, this Denon never misses a beat. It passes the laser blasts from speaker to speaker in a wonderfully coherent manner and, no matter the scene, creates a genuine sense of place. It’s always best to measure and be sure – and overestimate what you need to be sure you don’t run short.

Please note:

Thin wire such as 20AWG or 22AWG isn’t very common but occasionally can be useful for lower power speakers. Stranded vs solid conductors About the second question: I agree that the line with ‘too much’ isn’t clear. What we actually mean is that it’s better to go with an amp that can deliver more continuous power than the speaker requires. But there is a limit to this. A speaker usually has a maximum power capacity specified, which is the absolute maximum amount of power a speaker can handle in short bursts. More information about matching speakers and amplifiers can be found in our blog on the difference between passive and active speakers. What have we learned? Unlike pure copper wire, copper-clad aluminum uses an aluminum wire core with a thin copper plating. From the outside, it misleadingly looks the same because of the plating. Whichever surround sound system you're considering, do your research and make sure it will fit your space and accommodate your games console, 4K Blu-ray player, set-top box, and whatever else you're planning on hooking up. And that you can afford it, of course. Happy listening!

In terms of supported audio formats, the A7000 excels itself and includes Dolby Atmos(in both the Digital+ and TrueHD formats), DTS:X, LPCM, hi-res wireless audio and Sony 360 Reality Audio. The tautness and dexterity of the SW-10 is remarkable. It's an incredibly musical sub blending seamlessly with the smaller speakers, which themselves have an impressively well-integrated low end. The result is a rich and lively sound. Hopefully, you now feel confident and informed enough to make a choice based on the facts instead of the fiction. Still not entirely sure if that new amp or speaker will work well for you? Simply put your question in a comment below!

However, there’s a problem.Most speaker wire sold today is made up of two conductors attached as a pair with one marked as the positive; they’re essentially the same as stranded power cable paired together. The gauges available range from about 20 gauge to 10 gauge, with 18 gauge being one the most popular. However, the Sony HT-A7000 is an outstanding, future-proofed, all-in-one performer with excellent integration if you have a newer Sony Bravia TV. Be sure to try to take curves & bends into account but don’t worry about getting it exactly right. Measure the distance and then add a few feet (an extra 2 feet or so is good) to account for curves and other little things that add up. To get a better understanding of how loud a speaker can go, you’ll need to look at a few other aspects. Sensitivity in dBs 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
