I would connect my Infinity ERS640 speakers to a Sony FH-15R amplifier. The amplifier speaker line indicate 6 - 16 ohms. I measured the impedance of the Infinity ERS640 speakers and found 2.5 ohms. Can I still make the connection? Thanks,

Is the amp bridged? If you only have one speaker connected to it, I sure hope so. How much power can that speaker safely handle and what is the impedance of the speaker? 2,4,8 ohm? A 1200 watt amp with only one speaker may be too much amp.
Since you have Only one common main output,you can hook up your speaker, its either in series or parallel connection depending on the impedance in your amplifier,impedance in OHMS,(8ohms/4 ohms/16 ohms) please see the impedance level at the speaker terminals of your amplifier, Thank you,
I don't think it has anything to do with the impedance. The amp and speakers are well in the allowed limits. The only time this is a problem is if you connect an amp with a greater impedance then the speakers. This sounds like something to do with the HK 990. It could have a fault on it. You could try listening with headphones if the HK 990 has a socket for them. If they have low sound, there's an electrical fault in the power amp of the HK 990.
You have to check the ohms of the speakers all spekers should be 8 Ohms or above. if not it will overload the amplifier at high level. The minium ohms impedence of the amplifier is 4 ohms. If you connect two 8 ohms speakers together then the effective ohms will be 4 OHMS then the amp will handle the speakers. If you connect two 4 ohms spekers together then the effective ohms will be 2 Ohms, this will overload the amplifier. You will be able to connect two 8 ohms speaker to left channel or right channel of the amplifier. Check the speaker spesifiction to know its ohms. Make sure all the speakers have an impedence of 8 OHMS or above
Yes it is important that the speakers you are connecting to the new amplifier is working good and having equal impedance inthe left and right channels. hence if you are confimed that the speakerr is faulty first of all replace the speaker or the speaker coils and diaphragm before you connect to the amplifier to be powered. Please also check if the network has any damage before taking an impedance check. This should be identtical to both the channels. If so you are ready to use your new amplifier. Hope this helps to guide you. Good day
First of all the 70 volt line is used when we are dragging long lengths of speaker wires. hence to counter the drop we use a high voltage line brring it further down without any remarkable drop and use a step down matching transformer to power the speaker according to the impedance of the speaker to the secondary of the transformer. Connect the 70 volt to the 70 volt output in the amplifier. Now connect the other end of the wires tto the primary of the 70 volt transformer. Use the secondary output to connect to the speaker using the tap most suitable..2, 4,6,8 ohms . Check the phasing when you connect or reverse if the bass quality is less.
Hope this helps. Good day
check your amplifier output speaker impedance requirements.. example: 8 ohms...build a speaker 8 ohms in parallel or series connection.. check the impedance using ohmeter ..you must reach the required impedance..
use 1 cell battery to check if you speakers are in-phase...if one speaker did not ..reverse connection and check again ...to give the good sound...hope you understand my english..:)
on ur subwoofer u will see HPF output, connect this output to MAIN IN of ur power amp (first remove jumper between pre-out and main in from ur power amp) connect pre-out of ur power amp to input 2 L&R (Left is also for mono input). the HFP selector switch will cut off 80Hz or 100Hz to the main input depending on the position enabling u to have high frequency sound on your main speakers. connect the speakers to the main output terminal of ur power amp. do not connect speakers on the woofer ouput.
make sure u are using the right impedance speakers. do not switch speaker impedance selector while the unit is on.
