I have a new set of Onkyo SKF 4800 speakers (130 watts) https://www.intl.onkyo.com/products/speakers/center_surround/skf-4800/index.html I’m looking for amp recommendations, make, model and recommend wattage that I could consider using to drive the speakers just for home use and when need outside 2nd channel to switch over for the 2 x 150-watt speaker built in to the underside of the eaves. The amp does not have to be the latest or most modern, it could even be a good 2nd hand amp. Thanks in advance. https://www.intl.onkyo.com/products/speakers/center_surround/skf-4800/index.html |

Set a budget and tell us whether you are setting up a two channel system with a subwoofer or a multi-channel system. Tell us what you own now and what you think you might like to own in the future. How familiar are you with other than mass market lines? Do you know NAD and Cambridge? Are there other than mass market lines available to you for an audition? Is there an independent audio shop in your area that you will buy from? Or, just big box stores? Or, are you just going a buy something on line? There are more questions and more considerations to get in to but start there. . |

New member Username: WabPost Number: 2 Registered: Sep-18 | Thanks for the reply. Lets keep it simple. Lets do this step by step. Knowing what the the in house speakers are https://www.intl.onkyo.com/products/speakers/center_surround/skf-4800/index.html What would the recommended wattage be? For the under eave speaker they are just 2 big mid range 150 watt speakers and can be driven by a separate amp a JEDIA JPA 1240A https://www.amazon.co.uk/JEDIA-JPA-1240A-ZONE-MIXER-AMP-Amplifiers/dp/6095023386 Or to use that amp for both speakers, long story I don't want to throw a lot of money at something that I might listen to for an hour or so no a weekend. I hope that makes it clearer, thanks. |

Speakers don't have watts, only amplifiers produce watts. There is no "maximum" wattage you can apply to a speaker since it is the nature of the signal that counts. That is to say, there is no such thing as a "XXX watts" speaker. A highly percussive signal will be more difficult for a speaker to sustain for long time periods vs a less percussive sound. Bass is typically more damaging to the loudspeaker long term than would be high frequencies. Most speakers can do large amounts of midrange/vocals all day without damage no matter the wattage. Amplifiers "clip"; https://www.google.com/search?q=what+is+amplifier+clipping&rlz=1CAACAY_enUS754US 756&oq=what+is+amplifier+clipping&aqs=chrome..69i57.5683j0j1&sourceid=chrome&ie= UTF-8 Clipping occurs in the amp when it can no longer produce sufficient wattage to cleanly reproduce the signal. Though it takes far more wattage to reproduce bass than high frequencies (if there are 50 watts going to the woofer, there may only be 5 watts going to the tweeter), it is typically the distortions which accompany clipping (which occur as high frequencies) that will damage the tweeter before it damages the woofer. How many watts you should buy is, one more than you'll ever need. Using sinewave test signals, electrical sensitivity determines how loud the speaker will play when one watt of power is applied to the input terminals of the speaker. Onkyo gives no spec for sensitivity. I can only assume and average figure, which would be around 87dB with one watt in. Given that number as "average", most speakers can get reasonably loud with about 25 to 35 watts of power. With a 35 watt amp, your average output will remain less than five watts, which leaves plenty of headroom if you have 30 more in reserve. Buying more watts doesn't gain you much, particularly if they are not high quality watts. My first recommendation would be for a NAD integrated amp: ; https://www.audioadvisor.com/products.asp?dept=9 If you need a tuner (a radio), then go with a receiver. The two best lines beneath $1k are Harman Kardon and Outlaw. https://www.google.com/search?q=harman+kardon+amplifiers&rlz=1CAACAY_enUS754US75 6&oq=harman+kardon+amplifiers&aqs=chrome..69i57.14278j0j1&sourceid=chrome&ie=UTF -8 http://www.outlawaudio.com/products/preamps.html There are literally hundreds of used products that would work for you but I can't recommend any since I don't know what's available to you. Also, if used gear is out of warranty, you may be buying an expensive door stop. Hope that helps. Ask more questions if you need more help. . |
