Equalizers What are speakers? Speakers are devices that convert electrical signals amplified by the amplifier, into vibrations of air that can be heard by humans as sound. Speakers come in various shapes and sizes, types and models. Speaker types, based on amplification method There are two main types of speaker, based on where the signal is amplified. The characteristics of each type is described below. These speakers require a separate power amplifier in order to produce sound.
Apr 4 – Fixing them right will probably cost more than they are worth anyway. By the way, there are NO transistors in a crossover; it will consist of inductors coils , capacitors, and maybe a resistor or two. Technics SB-A32 is the number of the speakers, not the amplifier. It will have a model number on it somewhere.
The wattage rating you gave was the total maximum AC power it will draw from the wall, which has nothing to do with its audio power rating.
The amplifier power must be rated for the impedance of the loudspeaker (2, 4, 8 or 16 ohms). Here’s an example. Suppose the impedance of your speaker is 4 ohms, .
The speaker is an open-baffle loudspeaker, a configuration that has been gaining popularity in DIY circles in recent years. The emphasis in the tutorial is intended to be on the use of the miniDSP, and not so much on the speaker itself. So I hope that you will find the tutorial useful even if you are using the miniDSP for a more conventional boxed 3-way or 4-way loudspeaker. This article is Part 1 of the full tutorial. In this part, I will get as far as getting the crossover running and some basic measurements and equalization.
Inside this teensy little box is an embedded digital signal processor DSP , along with power supply regulation, a two-channel analog-to-digital converter ADC , and a four-channel digital-to-analog converter DAC. There are quite a number of these available from the miniDSP online store. For this tutorial, we will be using the 4-way PEQ plugin. This plugin turns the miniDSP into a mono 4-way crossover with a raft of parametric equalizers that we will use to correct driver, baffle, and room responses.
If you have speakers already connected to your stereo, fully disconnect them. Active crossover units are larger than passive ones and need to be mounted in a stable location, ideally near your amplifiers. Using the appropriate cables, wire your crossover into the receiver or preamp, with the wires coming out of the receiver going into the “in” terminals on the crossover.
Feb 23, · you can hook up an amp for tweeters, midrange, lows, and subs usually when you buy an amp it is just accepted that it is for a sub but if you need to beef up the other frequencys go for it just make sure you don’t overpower the speakers and you should be fineStatus: Resolved.
Power Supplies A constant current source source can supply a fixed current to a load regardless of input voltage or load change. The LM is quite useful as a constant current source, works on a wide input voltage range, from 3V up to 40V. The circuit is rather simple, uses only one transistor and few passive components and performs well in terms of frequency stability, almost zero drifting after about 4 hours of continuous operation.
With 12 volt DC it will deliver 1 watt RF power. The most important parts of the oscillator are the transistor Q1 and the tuned circuit, which comprises the inductor Ll and the variable capacitor CV1. When the battery is first connected, a brief surge of current flows from the collector to the emitter of Q1, causing an oscillating i.
An oscillating voltage therefore appears at the junction of Ll and CV1. The frequency of the oscillation depends on the values of Ll and CV1, so that varying the value of CV1 tunes the oscillations to the exact frequency required. In order to achieve a high output level, you will need a well tuned antenna, and a large heatsink to dissipate the heat from T2 transistor. Transmitter was mounted in metal enclosure and works extremely well.
A built-in limiter extends this ability by preventing distortion that can arise out of sudden peaks, taking the audio from merely impressive to completely immersive. For the listener, this structure means powerful heart-thumping bass with such low distortion that individual sounds remain both accurate and articulate, even at sustained low frequencies. This is the kind of bass that takes surround sound from simply a listening experience to a seemingly tangible, robust environment.
Sealed enclosure Power and accuracy normally do not go hand in hand. The Studio P, however, is by no means a mere normal subwoofer.
This Dayton Audio SA W Subwoofer Amplifier is a straight drop in replacement for my blown KLH ASWC subwoofer plate amp. The Dayton has left/right banana plug inputs/outputs as well as a left and right line level RCA plug inputs making it more compatible with newer equipment than the original KLH s:
Monday, 27 August Crossovers Basically, crossovers are little electrical devices that receive a fullrange signal and divide it into separate outputs of midrange frequencies, lowrange frequencies, and highrange frequencies. That way, the highs are sent only to the speakers designed for the highs, the lows are sent only to the speakers designed for the lows, and the mids are sent only to the speakers designed for the mids.
Passive crossovers do this by dividing the signal after it leaves the power amp while active crossovers do this by dividing the signal before it gets to the power amps. Passive crossovers located inside full range speaker cabinets are good in that they make it possible to provide a full range of sound using only one amplifier, but they are a little inefficient. Since all the speakers are working from the same source, the low speakers, which require more power, will tend to rob power from the higher frequency speakers and horns.
Active crossovers plugged in-line before the amplifiers are good in that they make it possible to power the mids, lows, and highs from different amplifiers. This way you can use a big super-duper amplifier for your lows, and use a smaller amp for the mids and highs. This is a much more efficient use of power, and it gives you the ability to acquire a much more powerful and full sound. The catch is that using an active crossover requires a lot more equipment and expense.
Using an active crossover in a system is sometimes called bi-amping or tri-amping. Below is an example of tri-amping the mains in a mono system. Tri-Amping the Mains The effects loop and the monitor system should be connected in the same way as before, but now the mains have been turned into a tri-amped system. To do this, a crossover, three separate amplifiers, and three separate sets of speaker cabinets must be used.
And back at installing more electronics into my car. No subs this time, and no 3 or 4 amps. So, I searched and searched for an answer to this question in the forums but couldn’t locate anything, so I figured I’d run it by you all in a new topic. My question where I need opinions or advice this time has to do with powering tweeters. In my past car audio systems, I’ve always run my tweeters from the head unit after I added amps and ran the other speakers off the amps. In some cases, I have even connected my tweeters to my dash speakers.

Speaker selection and amplifier power ratings Too often we receive speakers for warranty repair in which the woofer voice coils are frozen and charred. The voice coil that drives the cone has overheated and burnt. Sometimes the speaker cone even catches fire! Often these are brought to us in the belief that the repair will be covered by warranty. Unfortunately, in practically all of these cases, the failure is due to excessive power applied to the speaker, which is specifically excluded from coverage by manufacturer warranties.
Other applications such as studio monitoring, home theaters, etc, may have additional considerations, although the principles here are still valid. We have identified two primary causes for speaker failure: This usually burns up the voice coil in the woofers.
Let me say right up front that you only need to read this article if you are lucky enough that your group is getting bookings in large or outdoor venues. But if you have a good set of main PA speakers that are starting to sound strained at those large gigs, you might want to think about a next logical step. You can send comments, questions, or scathing diatribes to Larry at lmundy attbi.
If you have multiple amplifiers, use this method for each amplifier separately. So, hook up only one amplifier at a time, unhook it and move on to the next one. Amplifier Level Setting CD- AutoSound CD Step 2: Tuning Frequencies. Time to adjust the built-in crossovers on the amplifiers in your system. Most subwoofer amplifiers have a.
How to setup your subwoofer with the right subwoofer wiring diagram Learn how to correctly set up your subwoofer wiring diagram the first time. Need to learn how to properly wire those subwoofers? Depending on the power of your sub amp you need to present the correct load to the amplifier. This is done by making sure the sub drivers are wired correctly. When wiring multiple subs the more subs you use, more possibilities will and complexities arise.
This is done by wiring the positive of the amp to the positive of both subs. This works for dual voice coil subs too. Just wire the positive to the positive of both drivers. This will essentially halve the ohm load resistance of each coil. So two 4 ohm subs in parallel will be a 2 ohm load. This is done by wiring the positive the amp channel to one positive of one driver. Then take a wire from the negative of that same driver and jumper to the positive of the next driver.
Then take a jumper and go from the negative of the second driver back to the negative of the amplifier.
Click on the link above and type “Kicker” into the search box Kicker system installation and review By Resumespeed Kicker package with single 10″ subwoofer Components installed: Over many decades I have had dozens of different sound systems in as many vehicles, from factory systems to custom installs, from many different manufacturers. I have had my share of botched installs and issues with unmatched components, so the last few audio upgrades I decided to do myself. The Mopar Kicker system is especially worthwhile since it is custom designed for each vehicle, and its “plug and play” installation convenience.
The difference between the factory Boston Audio premium system and the upgraded Kicker system is absolutely amazing! I am more than impressed.
Jul 06, · The woofers in most 2-way active designs are reproducing audio well up into the midrange (typically 1,, Hz) so with the additional sub in place the main’s woofer range would be from whatever the internal crossover is preset to down to wherever the user has set the external crossover.
Or are they intended for active speakers or amplifier? I would expect an active subwoofer to have the crossover at line level since passive crossovers at speaker level are quite more expensive and lower in quality. If the crossover outputs are at line level, then you want to route the line signals out of your amplifier and the subwoofer line level signals back into your amplifier.
However, as one last hint: As opposed to your passive speakers, the subwoofer is not designed as a part of the overall system and its phase response will interact with that of your passive speakers at crossover frequencies. A subwoofer is a way to get more “oomph” with smaller equipment.
Resistance is measured in Ohms. A 4-ohm cabinet offers less resistance than a ohm cabinet allowing more wattage to the speakers and is therefore a GREATER load on your amp than the ohm cabinet. Up to an amplifier’s limit, using a lower ohm cabinet will deliver more power to your speakers although not necessarily more volume , but the trade-off in working your amp harder and hotter may not be worth it: When amplifiers suffer shorts in their output power transistors, they often deliver raw voltage into the speakers, immediately cooking the voice coils.
In my early days of tinkering with electronics, i destroyed two mint JBL speakers Earth solid-state power amp – the smoke and smell and feeling of horror is something i will probably never forget! The bottom line is that you won’t really know unless you try or find somebody with your amp who has tried it.
The power amplifier output will change, depending on the impedance of the speakers connected. For example, when connecting a pair of 8-ohm speakers and a pair of 4-ohm speakers to a Yamaha PS power amplifier in stereo, the output is as shown below.

Amp has a built-in class-D digital amplifier that delivers 55W per channel of audiophile quality sound to your speakers. You can even adjust the sound to get the bass, treble, balance, and loudness just the way you like it. And the aluminum casing passively cools the amplifier so all you hear is the music.
If you are new to the concept of multi-way DSP loudspeakers, please read the overview app note Digital Crossovers Basics first. Check out this app note for more details. All of the above options can also be used to generate a subwoofer output signal summed from the left and right input signals, for a two-way-plus-sub or 3-way-plus-sub configuration. Configure hardware The specifics of your hardware configuration depend on the nature of your project, the amplification that you have, and the miniDSP option that you chose above.
Here is an example of a 3-way-plus-sub configuration. The example shows a 6-channel amplifier for simplicity, but you can also use three stereo amplifiers, one for each pair of drivers tweeter, midrange, woofer.
When you call up the receiver’s speaker setup menu on-screen, there will be a question regarding whether you have a subwoofer running and what crossover frequency you want to use (some receivers may not give you a choice of frequency; they will likely be factory set at 80 Hz or Hz).
And while NHT never claimed that the original Zero was anything but a decent budget speaker, they’re calling the SuperZero a true high-end component that just happens to cost very little. But while the 3. Having become very familiar with the original Zero’s sound, I couldn’t believe the level of sound quality I was hearing from the Super version. Hey, I may lie, cheat, steal, swear, expectorate, saunter, and push over sleeping cows in the dead of night, but a man’s only as good as his word.
This acoustic-suspension driver is mated to a 1″ fabric-dome tweeter. The new mid-woofer is a better-behaved driver than that of the original Zero, with a smoother response at the top of its band. The crossover has also been upgraded to better integrate these higher-performance drivers. The drivers are crossed over at 2.
