If you like loud uncompressed music and your speakers are 90dB efficient, 200 Watts is likely plenty of power for you. If you only listen to light classical, jazz and don't expect them to rock the house, 50 Watts is adequate. Higher efficiency speakers, like horns, take very few Watts. Besides, how much Amp power do I need for my speakers?
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
Secondly, how much power do I need to drive a 4 ohm speaker? With a 4 ohm speaker, the maximum output power will be 200 watts. With a 16 ohm speaker, the maximum output power will be 50 watts.
Additionally, is more watts better for speakers?
Yes, it's true that the higher the power (watts), the louder and cleaner the speakers will play. Small differences in power, however, don't make much of an audible change. In order to perceptively hear a difference (a 3dB increase), the power would have to double.
How many watts per channel do you need?
One hundred watts per channel might not be enough, or 200 might be better, but an honest-to-God 300 watts might be what it takes to rock your world. Even if it's just the occasional party where you really want to blast the system, you need to buy enough power.

What happens if AMP is too powerful for speakers?
Most speaker damage occurs during an event called 'clipping'. This happens when you overdrive an underpowered amp. It's much harder to damage a speaker when using clean power. So if your speakers are rated 80-100 wpc, a 50 wpc amp has a much higher chance of damaging your speakers than a 300 wpc amp. Can I connect 4 speakers to a 2 channel amp?
There are two ways to wire four speakers to a two channel amplifier: in series or in parallel. Amplifiers have both a minimum and a maximum level of impedance and it is important to stay within these limits. As many speakers as your amplifier can handle can be wired together. How many watts do I need for outdoor speakers?
A pair of 60-watt patio speakers will give you great coverage in areas less than 300 square feet. For 300 to 500 square feet, look for 80 to 100-watt speakers; 150 watts to 175-watt speakers will cover 600 to 800 square feet with clear, sharp music sound at soft volumes. What happens if AMP is not powerful enough?
"Amplifier Distortion: The most common source of speaker damage results from amplifier distortion. Your amplifier may run out of clean power upon listening at loud levels. A direct consequence of such an overuse is distorted power, producing a greater quantity of distortion than its rated output power. Is a 1000 watt speaker loud?
It's a major indicator of a speaker's overall loudness, and one reason why a 1,000-watt speaker isn't necessarily louder than a 500-watt one. In fact, a 500-watt speaker with a sensitivity of 98dB will actually be the same volume as a 1,000-watt speaker with a sensitivity of 95dB. Is a 100w speaker loud?
The same thing holds true at higher wattages—a 100W amp is not going to sound twice as loud as a 50W amp; assuming identical speakers, it will only be 3 dB louder, which is noticeable, but definitely not a doubling of perceived loudness. How can I make my amplifier more powerful?
How to increase the power amplifier more powerful, double the transformer to upgrade the amplifier. Use 2 transformers Silicon for 1 amplifier to turn cheap amplifiers into brand amplifiers. Bass boost for more powerful speakers. The medium and treble for the speaker sound better. Is 50w channel enough?
For most people, 50 watts will be more than enough, and Denon's least expensive receiver, the AVR-1513, is rated at 110 watts per channel. Those speakers are extremely sensitive, they're rated at 101dB @ 2.83V, so they can play stupid-loud with a handful of watts. Is 25 watts loud enough?
Yes, a 25 watt tube amp is loud enough to play with all but the loudest drummers, assuming you don't need crystal cleans. If you do, look for 50 watts at least. Wattage tells you how clean an amp is, as you said in your comment, but only to a MUCH lesser degree, how LOUD an amp gets. Is 300 watts loud enough?
300 watts should be plenty. Especially if you have P.A. to carry the bass in the house. If it's not, then the rest of your band needs to turn down and/or buy some P.A. Are 10 watt speakers good?
Three watts sounds twice as loud as . 3 watts so you being a musician makes sense. Either you like loud music or you have been exposed to very loud music too long and it doesn't sound as loud anymore. Either way, 10 watts is plenty loud for most living rooms and most people. Does more watts per channel mean better sound?
That's what power gets you--the more power you put into a given speaker--the louder it will play. More watts aren't necessarily better sounding watts; some hard-core audiophiles get off listening to ultra low power, 7 watt per channel, hand-built, vacuum tube amplifiers. Does more watts mean more bass?
More watts = better bass response. Bass frequencies require more power to be loud as opposed to mids and treble frequencies; the lower the frequency, the more power is required for it to be louder. This is why many people prefer to play their 100 or 120 watt heads at bedroom volume, due to the bass response. Which is better 4ohm or 8ohm speakers?
4 Ohm Vs. 8 Ohm. A 4-ohm speaker requires more power from an amplifier than an 8-ohm speaker to produce the same loudness of sound. This is due to the relationship between voltage, current and resistance in electronic circuits; for a given voltage, a lower impedance means a greater current. How loud is 3 watts?
3 watts is 43% as loud as 50 watts. 2 watts is 38% as loud as 50 watts. 1 watt is 31% as loud as 50 watts. 3/4 watt is 28% as loud as 50 watts. Are 6 watt speakers loud?
6 watts is unlikely to be uncomfortably loud--even in a small room, but remember that the instrument has a volume control. You can adjust it to your comfort level. Do 4 ohm speakers sound better?
4 ohm speakers place a significantly heavier demand on power amplifiers as compared to 8 ohm speakers. Because of their lower impedance, twice as much current will flow through a 4 ohm speaker (as compared to an 8 ohm speaker) for a given volume control setting (assuming the amp can keep up). What hits harder 2ohm or 4ohm?
A subwoofer with a lower electrical resistance produces a louder sound than one with a high electrical resistance, which means that 2ohm subwoofers are louder than 4ohm ones. Although louder, 2 ohm subwoofers are also more likely to produce a poorer quality of sound due to its' power consumption. Can I use 4 ohm speakers?
Can I use 4 ohm speakers with my AV receiver or power amp? Yes, you can. If using 4 ohm rated speakers, common sense should always be taken as to the volume level setting, as it is easier to overdrive or "clip" an amplifier with 4 ohm speakers than with speakers with a rating of 6-16 ohms. Are higher ohms better for speakers?
Since impedance is a measure of how much the speaker resists current, the lower the impedance in ohms, the more power the speaker will draw from your receiver. Because of that, a 4 ohm speaker is considered more “power hungry” and will tax your amp more than a 6 or 8 ohm speaker. Can I use an 8 ohm speaker with a 4 ohm amp?
Yes, but use two 8 ohm speakers wired in parallel on each speaker output port. That being said, you can also put a single 8 ohm speaker load on an output designed for a 4 ohm load, but you won't get the same quality output as you would if you were to use the load for which the stereo is designed. What happens if speaker impedance is too low?
Too low an impedance will result in weak output and poor tone. If the speaker impedance is higher than that of the amplifier, its power output will again be less than it is capable of. Can you mix speakers with different ohms?
You can connect speakers of any impedance to an amplifier and they will work. However, if the amplifier isn't designed to drive speakers with a lower impedance (4 ohms for example), then the amplifier may overheat if you turn the volume up very loud. Can I use 4 ohm speakers with 2 ohm amp?
It doesn't have to be 2 ohm, 4 ohm speakers will work just fine, it would just be 3 dB less efficient assuming both of the speakers are of the same sensitivity. How do you match speakers to an amplifier?
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load. Is 1 ohm or 4 ohm better?
resistance doesn't affect sound quality. Like Blaine said, 4 ohms is better, but usually not enough to justify 4 ohm over 1 ohm for most people. There's so other factors to worry about in a system before worrying about which ohm load sounds better. Is 100 watts per channel enough?
In general, receivers with about 100 watts per channel (accurately measured) are more than powerful enough in just about any home theater. Is 60 watts per channel enough?
I found 60 Watts/ch to be perfectly adequate on 93 dB/Watt speakers for "loud" levels supporting peaks over 105dB and seating about 8-10 feet away. A more moderate level buys you the luxury of some more distance, less Watts, and less efficient speakers -- probably still with more headroom to boot. Is 15 watts per channel enough?
A high-efficiency speaker may require less than 10 watts per channel to drive it adequately. A low-efficiency speaker usually takes at least twice as much power. If each of your speakers requires 15 watts to drive it, then your receiver must deliver at least 15 watts per channel. Simple, so far. What is a good dB for speakers?
The higher the sensitivity rating, the louder your speaker is. An average speaker comes with a sensitivity of around 87 dB to 88 dB. A speaker with a sensitivity rating over 90 dB is considered excellent. Is more watts better for subwoofers?
The watt rating is a rough guide to how loud a subwoofer might be able to play, but it doesn't have to be louder. You always control the volume. In fact, a 1,000-watt sub may sound better at "regular" room volumes than a 100-watt sub. Though quite common, 100-watts really isn't that much when we're talking subs. How many watts do I need in a receiver?
In general, receivers with about 100 watts per channel (accurately measured) are more than powerful enough in just about any home theater.
