Check speaker cable for open circuit cable-repeat your setup again and confirm all speaker are in on status-last thing defective speaker itself.(sure you replace it)

The woofer doesnot work and the horn is working but not as usual


First you need to verify that there is nothing wrong with your amplifier. Simply swap speakers around and see if the fault follows the faulty speaker or stays on that channel. If the speaker is at fault I would hazard a guess and say, that the woofer has burnt out and is now a high resistance. This would then increase the total impedance of the speaker circuit and make the horn speaker sound the way you described. This can be verified with an ohm meter. Total impedance should be about 4 to 8 ohms. The only real remedy is to replace the faulty speaker woofer. Sorry

4 ohm and 8 ohm speakers


You can plug in higher ohm speakers , the higher the ohm the higher the resistance is, it is a danger when you plug lower ohm speakers into a higer ohm Amp , at a high volume that will cause them to blow , the center speaker would be fine to use a higer ohm speaker , your best choice is to buy a Active Subwoofer, which means the sub has it's own power supply , and u can blast the thing as much as u like , thn u can turn the bass down on all the other speaker's so u can play it louder , and have the sub turned up has high as u like , this is the best way to get great sound with high volume , buy a Active sub woofer , any active subwoofer is ok , a active sub woofer has its own volume and inputs on the speaker ,

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.

I have two JBL MRX 515 speakers at 8 ohnms and two behringer bins at 300 watts 4 ohms running off a behringer EP4000 amp, would this be ok ? and not casue any damage to the speakers

It's ohm's law, dude. 1/a + 1/b = 1/total. One each 8- and 4-ohm speaker in parallel per channel would be 2.7 ohms (nominal). So it will work in theory.

How you manage the potential difference in volume between dissimilar speakers on the same amp channel is a mystery.

Distortion will kill any speaker, not power. Stay within the amp's usable range.

Which amplifier that match 2 of JBL CM52 speaker and 2 of Bose 151


If you want to run both the speakers at a time you will have to buy a professional amplifier like CROWN XLS202.
Because together the total impedance will drop below 3 Ohms. An average domestic amplifier is designed to run speakers between 4 to 8 Ohms.
If you are running only one pair at a time you can buy any of the following Amplifiers.
Marantz - PM 7003
NAD C356

I have a 1200watt amp that's only providing 300watt output with 8ohm Behringer B212 speakers. Is there a resolution and what would it be?


I'd need to know more about the amp, but don't forget, amps are rated as their max power...
So lets take a 300W/channel stereo amp at 8 ohms.
Ok, it's stereo, so there's 600W
But the amp is capable of 4 ohm loads...well, now you can deliver 600W/channel, for a total of 1200W
In this scenario, your amp is doing exactly what it was designed to do with those speakers.
If you wanted to get the full 1200W out of the amp, you'd have to hook up 2 more speakers in parallel to the ones already there. This drops the impedance to 4 ohms per channel = 600W / channel.
Yes, the power is split among the apeakers...300W per speaker into 4 speakers = 1200W
so any way you look at it, there's your 1200W

I have bought a Sony Home theatre with total 6 speakers (including woofer, rear speakers (2), Front speakers with stand(2) and onr central speaker. But the centre speaker is not responding during TV,...


That would all be a function of your HTS, not necessarily the speakers.

Get a handle on how IT works, maybe find the manual and perform setup to verify the speakers work at proper levels.

I imagine it has several Digital Sound Processing modes that can create multi-speaker sound from any source.

The charge to the speakers do not last as long as it used to. Do we need to purchase new batteries and if so how do we change?


Yes definately new batteries. Depending on use I find you can get about 2 years service out of a set of NiMH or NiCD batteries. can you show a photo of the back of the rock?

Lost almost all sound in both speakers


Test the speakers on a bench if possible with a different receiver and some new wire. Or if you have a multimeter check the impedance, should be 8ohms if it's got a short, it will read 1..... or ....1 If the speaker wire when connected to the outdoor speaker is not siliconed, it acts as a wic and will oxidize the wiring and cause a short. do you have a separate volume control for them? and is that volume control indoor or outdoor? is it connected to a receiver or amplifier? The fastest test though would be to hook up the rock spkrs directly to another unit. If you still have trouble, reply and I will help you troubleshoot further. Hope this helps
