The speaker has a low power output


The output of a speaker primarily depends on system design (obviously) However, perhaps you have sourced a replacement or 'upgrade' speaker for an existing system. In that case, perhaps you have an impedance mismatch. If your amplifier is designed to drive, say, an 8 ohm speaker, and you connect a speaker of 16 ohms impedance, then your sound will be softer. On the other hand, you may have connected more than one speaker to one power amplifier output. If you connected in series you add the impedances. If connect in parallel you work out the impedance using this formula:
1/Answer= 1/Speaker A impedance + 1/Speaker B impedance + 1/Speaker C impedance etc. So if you connect three speakers in parallel, each of 8 ohm impedance:
1/Answer=1/8 + 1/8 + 1/8 = 3/8
3X Answer=8
Answer = 8/3 = a little less than 3 ohms.
Reducing the load like this makes the sound louder, but risks distortion or even damage. Check your manual for amplifier tolerances. Cheers, Don.

Connect speakers


All power amplifiers are designed to operate with a maximum current. This is limited by a minimum speaker impedance load. Your amplifier manual will specify the minimum load on output channels. High quality amplifiers can drive speakers with a combined impedance of 2 ohms or less. To calculate your parallel load, as you have requested, use the following formula. 1/Total load = 1/mgongo speaker impedance + 1/HW-E5500 speaker impedance.
Example. If your mgongo speakers have a nominal impedance of 8 ohms and the HW-E550 speakers have a nominal impedance of 8 ohms, then the formula is 1/Answer=1/8 + 1/8
1/Answer = 2/8
1/Answer = 1/4
Answer = 4.
If your amplifier can drive a 4 ohm speaker load without clipping then you are OK.

Impedance setting on Yamaha AV Receiver


Hi. You can always use a Receiver with an output impedance that is lower than the speakers input impedance.Problems arise when you try to use a Receiver with a higher output impedance than the Speakers input impedance.

Receiver 6 ohms speakers 8 ohms......YES..
Receiver 8 ohms Speakers 6 ohms.......YES, WITH CAUTION

What is the impedance of the JAMO A3SUB.3 speaker?


22K is the impedance listed in the specs but you may have to look on the actual speaker itself to get the impedance of the physical speaker.

I have a kenwood 350watt amp on 2 mtx thunder 12's


Hello
Check the impedence of the connected speakers. if any impedence mismatch is there, the amp will sense it and will cuto the output OFF. Use only specified speakers only. The impedence of speakres are expressed in "Ohms". Select all speakers of same impedence. If 6 Ohms is the output impedence of the amp, use only that Ohms speaker. Never use a speaker less that this Ohms. You can use a higher impedence speaker, say 8 Ohs or 16Ohms. But never use lower impedence speakers, of connect two speakers in parellel connection, which will relult in overloading. I think that I've made a satisfactory solution to you. Please don't hesitate to rate this solution. Good luck
Wish you a Merry X'mas and Happy 2012.

How come my two subs wont get powered with a 12 ohm load. is it to high of a load. they are 12


HelloCheck the output impedence [indicated in OHms]]. You can get it from its manual. If it is designated as; 8OHms for example; you can connect one 8OHMs speaker direltly, or two 4 OHMs speakers in serieal connection. Likeways, if the output impedence is 6OHms, you can connect one 6OHms speaker direltely, or 2 12OHMs speakers in parellel. Just see, when we connect thow speakers in serieal, the impedence will be the sum of both speaker impedences. if we connect the same in parellel, the impedence will get halved. OK.

I just purchased a yamaha RX-V767 receiver. I have a polk surround sound speaker system 5.1 that have an impededance of 8 ohms. The receiver has an impedece adjustment knob on it. would it be safe to...


No, you don't want to do that. The Ohm output on the amplifier must match the speakers. Run 8 Ohm speakers on 8 Ohm and run all your speakers on the same impedance (Ohms). Your gonna burn your amplifier up if you run different impedances.

MY AMPPLIFIER KEEPS BLOWING THE FUSES WHEN IT REACHES HIGH VOL. i HAVE IT BRIDGED WITH THREE 10" SPEAKERS.


LOOK THE SPEAKER AND IMPEDANCE WILL SAME TO OUTPUT OF AMPLIFIER OR LOOK FOR THE OTHER SPEAKER WHICH MORE IMPEDANCE,FOR EXAMPLE ,IF YOUR SPEAKER HAVE 4 OHM PUT THE SPEAKER IN SERIE FOR INCREASER THE IMPEDANCE,NEVER CHANGE THE FUSE FOR A TO HIGT.
