How to bi-amp wire a JBL EC35 speaker?

I perchased a used EC35 without the manual and I want use my home stereo amp to power it but I can't bridge the amp to 1 channel so I'm wondering if I could ether use each channel to power 1 pair of inputs(the box has 2 pair of inputs) without damaging the speaker.the amp's output is rated at 45w each channel into a 8ohm load. Do I need a some form of crossover between the amp and the speaker or can i just use the high pass filter in my processor to do the filtering?oh what setting should I use(150,100 or 80hz) that's the only settings it has for the center channel output .

With help from a other site I bi-wired it using a bigger amp. It now gets 105w at 8ohm using a 18 octive slope filter set at 80hz.

I bought a Denon AVR-2807 used from eBay, I got it hooked up properly to my speakers, JBL E100 front bi-amped, JBL EC35 center and E50 rears, no subwoofer. HDMI from PS3 to Denon and HDMI from Denon to...


TMI.

This is strictly a remote control failure.

Read this procedure to possibly fix the remote:
http://remotes.com/remotes/servlet/rs?a=Display&contents=help_deadremote&uuid=A12963989782821
They also sell replacement remotes.
Or look on eBay, usually much cheaper if available.

Another thing would be to make sure the receiver's remote eye isn't picking up infrared from anything else in the environment.

I have a Tech pro 4100watt amp and 2 JBL jrx125 dual 15inch speakers. What is the best way to hook them up? Bridged off of one channel or stereo off of seperate channels?


for maximum Bass, you will want them bridged, it should show on the amp how to bridge them using the positive on one channel and the negative on the other channel. Stereo will have a more true sound but less bass.

hope this helps and good luck

How do you bridge a JBL GTO7001 amp


JBL do not suggest bridging this amplifier. As it is a mono block, the "stereo outputs that are on the amplifier go to the same contacts inside", so effectively both Left and Right outputs are the same, (like using a headphone splitter.) this is designed for ease of use when installing more than one subwoofer. if you run your sub/s at two ohms you will be able to get the full 700WRMS out of this unit.
so in effect if you "bridge" this amplifier it will not be any different if you hadn't. Bridging is designed for TWO or more channel amplifiers to increase the power going to the speakers, but not needed in a mono block amplifier.
I hope i have helped you with your problem and please dont forget to rate my solution.
cheers

Will Bi-wiring these speakers give a noticable difference in audio sound quality ?...I'm using them with a Harman Kardon HK 3490 receiver..


Hi gregorygoff
This speaker is already having its own crossover PCB inside the box, the xover frequencies are all set as per the speaker's response. So, there will be no point making it Bi-wired.

How do i bi amp sx 1250 to get both channels of each side to work together


you are actually not bi-amping the unit, you are bridging the amp. this really only works as long as all channels produce equal power. next the bad news is that typically home stereo amps are not wired internally to bridge channels.

bi-amping a speaker refers to connecting on channel to the highs and on channel to the lows. the receiver would need to be be able to process the outputs via a crossover network to split the frequency range in half so the appropriate frequencies went to the correct speaker.

What do you mean by the subs should have more watts than the amp.and subs mean woofer ? actually i dont know any thing abt this. what is 8 ohm stereo, 8 ohm bridged,4 ohm stereo. etc etc...?


If your planning on using a stereo system in your car or home you need to follow some rules otherwise your just wasting money. The watts of a speaker means how much power it can handle. The higher the number the more power it can handle, and usually the louder it can get without distorting. If your amp has more power or close to the wattage rating of the speaker you will blow the speaker, it can even get so hot it ignites. The amount of ohms is the electrical resistance the speaker provides. House speakers usually have 8 ohms where car speakers tend to use 4. 8 ohm stereo means your left and your right are separate channels and each speaker has 8 ohms. 8 ohms bridged means you bridge the left and right channel to increase the power output of the amp and you have to use either 1 8 ohm speaker, or 2 4ohm speakers in parallel to prevent damage to the system. Same goes for 4 ohms. If I remember correctly you want your sub(woofer) to have a wattage rating 20% higher than the amp. Remember if the speaker overheats its no good, but most amps if they overheat they just shut off until they cool off, but only if they state they have a thermal overload protection.

I have a jbl W15GTi MKII 15 inch and on the speaker it has to a a an b side and two wires no each side how do you hook it up


Your speaker has dual voice coils. You can hook it up so that it is 2 ohm or 4 ohm depending on wat the amp can handle. You can try hooking it up by matching the colors or like any other speaker.

JBL Sub Amp Wiring Please


it seems rather redundant to bridge a mono amp. Unless the instruction manual states otherwise, i would assume that one speaker output is identical to the other (ran in parallel, like an A or B speaker, not like Left or Right), and you would present the amp with a two ohm load by wiring one speaker to each output. Bridging it may or may not work, but, again, it just seems redundant.
