Want to use my current speakers with a new surround sound system. Current system is 5.1 channels, rated at 100w per channel @ 8. Ohms. New System is rated 145watts, 5.2 channels at 6 Ohms. Will b ok?


Hi Ronald.
8 Ohm speakers will work just fine as replacements for the
6 ohm speakers. When fitting speakers you need to consider
The power handling capability. The impedance and the frequencies
involved. Power handling is expressed in wattage ie 100W.
Unfortunately this can be expressed in rms, max or peak music. The rms value (root mean square) is the only really relevant figure as this is the continuose handling power at 1 KHz. The impedance
is the resistance that the amp sees but is not a dc resistance and
varies with frequency. The lower the impedance the more power
will be drawn from the amp. In the event of a short circuit across
the speaker the amp will try to deliver infinite power into an infinitly
small load in an infinitesimal amount of time and will self destruct.
Using an 8 Ohm speaker draws less power than a 6 Ohm speaker.
Connecting speakers in parallel; results in the impedance beingreduced. For example two 8 Ohm speakers in parallel will result
in a 4 Ohm impedance load but in series will be 16 Ohms.
Incidentally the the .1 (5.1) is the sub woofer which only has
to handle the bass frequencies, a small percentage of the
amplifiers overall frequency response..
Connect your speakers and then power up the amp last
after double checking there are no shorts on the speaker
cables.
All the very best from Vintie.

How do I open a UC-280 2.0CH USB Powered speaker system to reconnect the broken cable.


Once you open the speaker it will destroy the acoustic properties and make the speaker useless. The speakers are assembled with takp and glue and have to be pried apart.

It wont turn on, it shows 'push power protect' when you turn it on, or disconnect it and reconnect, i already attempted to disconnect the Sony Stereo MCH-EC909iP Mini Hi-Fi and it shows 'Push Power, P


The only thing I can think of is its goin into protection mode like an amplifier would, you maxed the volume out and it's protecting your speakers or you don't have the right voltage going to it, I can see you don't have it on a straight 120v plug and you might have the wiring wrong on the speakers to it might be too low of a ohm or too high

The feedback on my stereo is very muffled.


Does is sound this way with all audio inputs? You might have your speaker wires backwards Red to Black between the speakers and the Stereo, make sure they are red to red and black to black.

Hit the the speakers A/B/Off button on the receiver. If you plugged the front channels speaker wire next to the center channel on the back of the receiver make sure its showing B. If you plugged them in the banana plug part, make sure its showing A.

Sound problem with JBL Creature II


I had a problem with the speakers not working properly. The green lights lit, but the amount of sound coming from the speakers compared to that of the sub was much lower.
I decided to take it the speakers apart.
I found that the magnets on the speakers had moved forward slightly in the plastic cage they sat in. I pushed them back as far as they would go, and Hey Presto! working again!
I hope this helps someone!
