The speakers can handle about 45 watts rms a piece and the vr3 box can probabily handle 100 watts on its best day. your best bet is a 4 channel amp. use the front two channels for the jvc speakers and bridge the rear 2 channels for he vr3 box...keep the gains under 3/4 and tune the hrtz. fereq. to about 80 herts.hih pass filter on for the frot channel and low pass filter onfor the rear channel

What is the impedance of the midrange speaker and the tweeter speaker in the Pioneer cs r5100 ? I have the crossovers and the woofers I use for my front channels (L&R)


If you are running three 8 ohm speakers in parallel then the total impedance would be 2.667. If running two 8 ohm and one 6 ohm speaker in parallel you would have 2.4 ohms. This will burn out your amp pretty quick. And very possible won't play at all. Though I have never attempted to play a home amp down that low in ohms. Guessing you may have an older model Denon type amp.

Connect JVC MX-GT88 speakers to a differant reciever


If it has a bi-amp, you can connect the speakers to it. By the amplifier, if it's a stereo with bi-amp, be sure that it has at least 400 watts and up in order for the speakers to turn out great, if a receiver like a integrated amplifier, it may have like 2-10 connections, you can connect the speakers all together if it has more than 3 connections, if below 3, you may need to take the speakers apart and make it 3 way by connecting one wire to the tweeter, another wire from the tweeter to the main or mid speaker then one more wire from the main or mid speaker to the sub.

Mackie SRM 450, the main speaker has stopped working but the tweeter is OK, there is nothing coming from the speaker at all, no hiss, or clicks.


It could be 2 things:

*Blown Speaker or,
*Fried power amp output stage of woofer, since this speaker operates as a bi-amplified system it has separate amps for woofer/tweeter...

I have a couple active phobic loud speakers, one is completely out of commission and won't play anything. The other will play sound but only through the tweeter, while the speaker itself does nothing. I...


The tweeter is working but the woofer driver isn't which will change the impedance (ac resistance) of your amplifier output. The other speaker isn't working which will again, change the impedance even more. This could eventually damage the I.C. amps should you apply too much volume to the speakers.
You can turn the volume up to normal listening level and with your finger, slightly press the cone on the woofer in and out a couple of time. Does it engage in sound when you do this? If so, the woofer's coil is damaged and the woofer must be replaced. No sound? Open up the speaker (stereo off) and make sure both wires are fully secured to the woofer. Should they be attached securely, your woofer is probably defective. Should you have a crossover network, you can obtain a good, known working woof and temporarily wire it where the old woofer goes, turn on your stereo (minimal volume) which can verify the network pcb (crossover) is working.

I need replacement crossover because they got burn


The crossover in these is very simple and if it is burned, likely your speakers, maybe both, the woofer and tweeter have been damaged and need to be replaced. Test the speakers before changing the crossover. You MAY NOT notice the damage until you start driving the speakers again. The voice coil of the woofer is a common thing to fry, and while it may not open up, often it becomes unbonded to the coil form and rubs the magnet pole pieces. The tweeter/horn often wipes out the diaphram or blows the element open. Some of these are piezo horns and they can sometimes survive. These are rated at 100 Watts and if your amp can deliver over 50 watts you have to be careful to not put too much power into these. I have several of the Kustom 10 inch ones and several of the 15 inch ones... Also I have two 15 double stacks and they all seem to use the same crossover. Believe me, the crossover is far from what I would call "special" like the advertisements say. As an electrical engineer I was very disappointed. Anyway, test your speakers as they may be the worst of the problem.

How to install spr-17s


The six 1/2 speakers are your woofers,connect the positive and negative wires from the speaker to the 2 connections labeled on the crossover as W(woofer)+ pos and W(woofer) -- neg,hook the tweeters to the crossover connections labeled T(tweeter)+ pos and T(tweeter) -- neg,then hookup the 2 remaining connections labeled Amp to your amplifier,amp must be 2 or 4 channel stereo capable and give out enough power to properly drive the speakers so they achieve optimal performance.

My sub woofer stopped working, please tell me where it is located so i can check the speaker and also check if power is going to it thank you very much joe


The JBL premium sound system has a large woofer in the bottom of each door, a small mid-range speaker next to the woofer, & tweeters next to the front door windows in the corner, & two full-range speakers near the rear seats. The woofer (not sub-woofer) handles all the low end. You can test the woofer by turning the BASS to max and TREBLE to minimum (make sure balance and fader are centered) and put your ear next to each woofer.
The woofer is usually the 1st speaker to have problems after 10 years or so. The outer edge of the woofer starts to degrade. You will usually hear a rattling sound out of the woofer when this happens.
NOTE: If no sound at all out of the woofer (tweeters are OK), you might take your car into a car stereo shop. They can put a speaker on the wires connected to the speaker and make sure your problem is not the radio.
PROBLEM: You can still hear sound out of the woofers but it is distorted
SOLUTION 1: Go to a car audio shop and have them install new woofers. These may cost $30+ each but the dealer cost is over $200 for each woofer (crazy).
SOLUTION 2: More involved but very cost effective. If you or a friend is handy, you can go to www.speakerworks.com and order a new set of speaker outer rings (on the site they are called speaker SURROUND) that will replace the damaged outer rings on the woofers (replace on both woofers). They really work great and your speakers should last for many more years.
Hope this helps.

I bought a Behringer Eurolive B1220 Pro speaker with my PA system brand new and it sounded great at first. Now it sounds really muddy (the other 2 speakers I bought work fine) almost as if the horn has...


Bad news...you've blown the tweeters. Overdriving the mixer/amp creates distortion on the amplifier which heats up the speaker voice coils and eventually causes damage. Because of their small diameter voice coil windings the tweeters fail first (opens up like a fuse element does) followed by the woofer making a scraping sound (deformed voice coil) or not working as well. Warranty service because you blew out the tweeters? Don't get your hopes up.

1. PLEASE use enough power for the venue that you have. A high powered system will run all night at 10:00 (physical volume knob setting) than an underpowered system set for 2:00.

2. Get speakers off the ground and closer to your audience's ears. Audio from speakers on the floor must battle surfaces that actually absorb some of the sound....carpet, drapes, etc. And besides, legs can't hear that well.

Karaoke speaker,no woofer or midrange working, only tweeter


Hi, it's probably that the 8" woofer and the midrange of the "amped" enclosure is open. One way to test is to remove just one wire from the inside of the enclosure to the woofer or midrange in question and with the use of a continuity tester (or a VOM), check for the resistance of the coil of each the 2 speakers. Both should read anywhere from 4-8 ohms, if there's no reading (VOM needle will not move) then the coil(s) are open. In the absence of a tester, a single AAA or AA battery would do (pls. some would argue that this is not a sound practice, however this should be enough for you to be able to determine the condition of the coil(s)). With the use of the battery and a single short length of electrical wire, apply power from the battery to the terminals of the speaker, if the cone moves, then chances are it is good, if they don't then you would have to replace it. Am not sure if available in your area, but there are some trained people who can rewind the coil should a replacement speaker be not readily available. Hope this be of help. Please let us know how things turn up. Regards.
