    Helloooo there nice people thank you for stopping by to help me find a solution to my problem so ill get right into it... my 2 bar speakers are in a huge need of a amplifier and i have 2 kind of questions

    1) Could you help me find a nice amplifier with a good price not above 300 or so euro or dollars with bluetooth (IF possible)

    and

    2) a friend of mine told me that when picking an amp its better to get one with half the needed wats (rms) power what im trying to say (example):My speakers are rated at 300 "rms music power" so its best to get an amp that gives me 150 wats per channel because according to him the speakers will "much better".

    as far as i have see and read this would be false in many ways (Geek's will know)(and normal people that have knowledge in music :D)
    but i just wanted to ask in case its true :eek:

    any way.. soo

    What do i need the amp for... well even if it doesn't have bluetooth i want it to have a "good amount" of inputs and out puts since im going to add more speakers to the mix.. and see how it works out we are going for a 5.1 amp... or higher if the price and the features are good i dont know i just your help


    at any rate if you have something good to suggest please do for now im just seeing my options thank you for your time

    That's a bunch of malarkey. More speakers are actually damaged by using an underpowered amp than overpowered. Why? Distortion. When you push an underpowered amp to get the volume you want, "clipping" in the amplifier output occurs which basically sends a destructive square wave to the speaker drivers. It really is hard to damage a speaker with too much power playing music, as long as you don't try to overdrive the speaker (play them louder than designed). So you can put a 1000W amp on a 150W speaker and enjoy them for years. A good amp does not care if it is never pushed near its limits.

    Except you didn't say what you need it for. Listening to music? Watching movies with surround sound soundtracks? Computer gaming?

    The efficiency of your speakers plays a huge role in amplifier you need. But I can find nothing about those speakers. And I have to admit, "sinus power" is something I have never heard of and can find nothing on that either. And "music power" is not an industry standard term also.

    Understand when you say amp, that is just that, amplifiers. You still need a pre-amp to power the amp and the pre-amp also is used to connect a tuner, tape player, CD/DVD, turntable, etc.

    Are you sure you don't mean a receiver? A receiver has the amplifiers, pre-amp and tuner built into one box. An AV Receiver is used to connect to a home theater system to switch in and out video sources too, like cable TV and Blu-Ray players.

    Also, when you see 2.1, 5.1 or 7.1, the .1 typically stands for the subwoofer. And most subwoofers are self powered-they have their own amplifier built in. The "receiver" sends a "line level" (not amplified) signal to the subwoofer.

    We need more information.

    Thank you for coming Mr.bill

    So let me answer the questions one at a time

    1st what do i need it for music mainly and only music :D not planing for gaming movies or anything only musicaa :D

    2d Since im not an *english guy* as you saw from my gramar and my spelling yes i was talking about receivers
    im just not familiar what is the right term to call them amp's or receivers ..
    soo yeah receiver is what we are going for...

    (Side note: Sinus power=Rms its a "German word" for older models because Rms is too mainstream for them and they want to make our lifes harder xd..?

    38th Also about the number of chanels "5.1" i have another small system witch has a sub and some other small speakers on it.. and i want to hook them up all together (at least that's my plan)

    ALSO!!.. Thank you Mr.bill for your help to another topic wayy back at 2016 about pa speakers i made my pick and it was the sony model at the end

    Ill be waiting for your replay if you need more information let me know

    and as always Arigato* (thank you at japanise) (• ε •)

    Does it need to be new or are you willing to consider better quality and used?

    The speaker pulls power from the amp. If the amp doesn't have enough power it clips the signal resulting in the voice coil being stressed, overheated, and damaged. You want an amp that has adequate power. Good brands to look at are Yamaha and Onkyo.

    That may or may not be possible. Many small systems are designed to work only within the system they came with.

    I like Onkyo - that's what I use now. Denon is another brand to look for. Sony and Yamaha have some good offerings too.

    Ummm, not really. It accepts it.
    No, it doesn't work that way either. The output of an amplifier is based on the input level to that amp. So when you turn the "gain" up on the preamp, a larger input signal is delivered to the amplifier and the amplifier increases its output in a direct coloration to that input.

    The load (impedance) of the speaker affects the wattage out of the amp, but the speaker does not pull power. It accepts it - hopefully gracefully.

    A 10,000 watt amplifier can be over driven into clipping if the input is too high. It does not matter if the "load" (the speakers) can handle it or not. If your speakers are 1000W speakers and you drive a 100W amp into clipping, the resulting distorted near square wave signal sent to that speaker can still damage the speaker. That is because the distorted waveform is a waveform the speaker drivers are not designed to reproduce.

    Hmm i see well at any rate ill see what i can find Denon and onkyo is too expencive for my gusta xd
    oh also i found a Marantz nr1602 7.1 with a nice price used... how about it :? any ideas for the brand?

    also question when im saying im going to hook up some other speakers what do i mean...

    those speakers have some outputs that can be used to transfer the sound to some other speakers (Note: every speaker has its own power)(how i use my setup so far i use the sony outputs with an rca to jack 3.5 to play it with my hifi) so my idea is i cant use the same thing to my receiver use it's outputs or inputs to just transfer the sound to my other components (im sure what im trying to do is not good but meh... IN THE NAME OF SIENCE)

    well if that's not possible ill just use the reciver as a stand alone

    Do you require HDMI connections and\or RCA connections ?. If you don't require HDMI you can get a real good amp for under $100 with tons of RCA connections.

    Not much for ONKYO personally they sound some what flat for my taste but typically come with more options \ features than the others for the same price. In fact a older ONKYO 608 you could probably get for about $130-$140 second hand.

    Others i would look in to are Marantz ( not the slim bs ), NAD, Yamaha ( even a 475 should be enough, although might lack the RCA connections your after, DENON and ROTEL.

    I hope your not expecting too much from that speaker, brand speakers typically suck. I known Panasonic to do some good ones in the passed but typically sub par and SONY have a habit of making ones that look like there better more pricey ones too but still are not good how ever gotta start some were.

    I would have a look around for some online reviews more so in forums ( like http://www.avforum.com/forum/index.php) one the unit you your on about.

    But at any rate i dont want something cheap i want something that will get the job done and have a good quality is not about money is about to spend my penny's where they count

    Well older higher models drop in price, for example you can get a newish Yamaha RX-v475 secondhand for about $100 $150 which with have only a few RCA connections but 5 HDMI connections and blutooth,

    Or if you can deal with not having HDMI and possibly blutooth you can get a old High model Rotel for the same money.

    And if your good with electronic maybe this guy would ship and not cost to much if you live in the US http://www.ebay.com/itm/Onkyo-TX-SR...861841?hash=item237af6fb11:g:LAwAAOSw2xRYcP0V

    And if you like it pick another up with a different issue and just swap the HDMI board out but that's just me lol.

    ONKYO, Yamaha and SONY are going have more options at more reasonable price, ONKYO more so.

    Good sound is in the ear of the beholder, over the years i found that Yamaha are the more natural sound just like they advertise and to me sound a bit more uplifting than say ONKYO, Marantz being brighter sounding and typically more open.

    Whats the DVD player may i ask ?.

    And as Bill said better to have a amp that has more power than the speakers than the other way around.

    And i would not be surprised if that speaker clips too not due to under powering but though to much movement. Last pair of SONY's i had were rated 100w but could not take 30w RMS but this will depend on music you like too.

    So were you from ? ( Germany ? ).
    Whats the budget ?
    What size room you have ?

    To keep it simple and you think the Yamaha RX-V475 has enough connectors on it for you go for it, you could even go the 375 but you would loose the blutooth option but both have RCA connections and had HDMI connections. Keep in mind SONY and ONKYO, the latter typically features v's cost.

    Check ebay for your region see if you can get a good secondhand one for about $100

    Your electronics should sound "flat" BTW. That is, they should not introduce any enhancements on their own. They should just amplify what is inputted to them. If your room's acoustics absorb too much high end or boom too much bass, you use an equalizer to "flatten" it out again - assuming you want the "faithful" reproduction of the original recording. This is actually where lots of power can help. A flat response at the low end takes a lot of power reproduce.

    A quick Google search would show Onkyo is consistently among the best. Of course, with so many models in their lineup, and so many other brands to choose from, no one brand is on the top of the heap in every price range. But if I were buying today, I would probably start by looking at Denon first.

    The fact of the matter is, with most audio content being digital these days, tonal qualities of the better products vary little. In fact, most people cannot hear the difference especially as they age. The frequency response of human hearing, sadly, begins to degrade significantly in our early 20s, and goes downhill from there.

    This will be interesting (and disappointing) to most here.

    They should sound flat ?, no they should sound as intended as who ever made it. I was not trying to say flat is bad it just not my liking as to me it's boring.

    I don't care what Google says lol, it's all a matter of preference which i know you know. Because more people supposedly buy ONKYO don't mean in anyway they are better never mind better for who ever is looking in to getting a receiver.

    Reason i did recommend a ONKYO is they are good starting receiver with typically more features per dollar hence why i have own 5 over the time in the US, NAD being one of my favorites although would not recommend one to anyone more so new to this stuff as they don't last in my experience but the sound quality is real nice..

    I prefer a flat response as well when using quality equipment this works best for me. But on some lesser quality equipment I have found that EQing is needed to get the best sound.

    Onkyo is great. I bought the SR605 back when it first released and though it has been replaced recently with a Denon; the Onkyo still works just as good now as the day i bought it. Fantastic budget receiver. I have always loved Onkyo for providing tons of features at a lower cost but with the durability that Onkyo has always been known for. I do admit my denon beats it in every way but it is much newer. My HK 3490 is about the best home stereo amp I have owned. That thing is a beast.

    Don't get me wrong The Yamaha sound is flat but has a bit more energy dramatic range in the mid\highs i find. Gotta to remember this all depend on what you like and speakers you enjoy as i don't like metal tweeter's always find them a little harsh and like the soft dome but that's just me.

    Used to keep a laptop on top of my ONKYO 608 as it got frigging hot as hell i even put heatsinks on the HDMI board as temps were hitting 70c+ range. In fact if the HDMI board is not on the top of the unit i will not even buy it as it is a hot part of a receiver.

    I am hoping to try out a few more receivers by end of the year including Denon which i am sure as good as they were back in the 90's. Would like to try out a ROTEL too again but dam they are costly :p.


    I used to mess with equalizer's but over time they are just annoying and living were i do there isn't a bunch of HI FI shops around here, Realistic did a good one ( TANDY ) but a lot just add a terrible tone to the sound.

    The HK 3490 got a link to it ?.

    I haven't owned a standalone EQ in many years. Back then I used them all the time because I preferred the V shaped sound but as I got older and had more money to spend I realized that I preferred listening to my music the way it was intended. I have always believed that running flat will provide the sound as it was intended considering a lot of music is EQ'd when recorded. With good amps I have not even wanted an EQ. For me if I want to change the sound of my music I use one of my tube amps or I swap around my headphones. Doing this has provided that certain sound that I enjoy or that sound I'm in a mood for.

    The HK3490 is not made any longer but here is some info: https://www.crutchfield.com/p_532HK3490/Harman-Kardon-HK-3490.html

    size... hmmm lets talk about a small one ehhh

    <-80ft-> or so by 100ft

    but i since im new i dont mind if the vocals-eq-room size will effect the sound...
    sure i want clean and nice sound but for now im looking what are my options
    and how i can use my speakers the best i can

    Of course Harman & Kardon, actually a brand i have never tried, how consistent are they with their sound though models ?, for example Yamaha always aim for a natural sound.

    And always wanted to try a good valve amp but with my music range i been recommended not too and my mood for music changes day to day so be a load of messing about. And no space to have 2 systems setup sadly.

    Also guys question some recievers have on the back
    4-16 ohms
    8-16 ohms

    Ehh mine as you saw are 4-8 that means my speakers wont be good for that input of the reciever
    or just the reciever will feed them more (sound-power) and damage them :eek:?

    My first thought as well. Go find a Realistic tuner/amp from the 70's or 80's. I have one from the 60's, some home made speakers and it's the best sound of anything I've got. The tuner is fantastic too.
