Question about Acoustic Research ARS115PS Speaker

Acoustic Research ARS115PS Subwoofer, No Sound

Good evening: My Subwoofer stopped working. The problem is in the powered amp section, specifically the crossover circuit (so I've been told by a local electronics repair man). Specifically, the crossover circuit does not "fire" to trigger the output of sound in the proper spectrum. I know that the speaker is fine (I checked it with a separate sound source). So the question is, where do I go for repair (now that Audiovox has purchased A.R.)? The repair man told be that he could not figure out how to make the repair. I'm in the greater Los Angeles area (North and west).

I have the same problem with the smaller AR 112PS speaker and since Acoustic Research went out of business, I too have been looking for a solution. I may have found an alternative to throwing away this really nice speaker. I found a company on the web that appears to sell an amp that may fit nicely into this speaker enclosure for $99.00. Check it out...

Subwoofer makes noise like an untuned TV regardless of volume knob


I would suggest your crossover unit has failed in the speaker cabinet. The crossover circuit board separates the low and high frequency content of your stereos audio signal. The low frequencies go to the bass unit (woofer) and the high frequencies go to the tweeter speaker. If the capacitor on the crossover goes open or near open circuit then noise is introduced into the sound system. Replace either the capacitor or crossover unit.

Hello
It seems that the power supply section of your speaker systen has the fault. Check the fuse inside it. If it found blown out, never replace an other fuse in place. Check the power supply circuit board for any short circuited components in it, before replacing an other fuse.

Well it sounds like you need a mono block amplifier for the subwoofers. Subwoofers are ment for low frequency. If you try to run regular audio through the subwoofer the sound will become distorted at a high volume. If you have a crossover on the amplifier try putting it on LP. Also do not exceed the RMX rateing on the subwoofer because if you do they will also distort. If you try adding the mono block on to it and it is still doing it you may also be running to much power to the subwoofers.

KLH ASW8-100b Sub woofer. I need to know how to hook it up to my surround sound


Some specific model numbers might lead us to specific manuals and specific instructions.

Depends on your source and its amplifer complement. Some can drive a subwoofer directly while others just produce a Line Level subwoofer output for use by a separate amp feeding a subwoofer or self-amplified sub.

The set-up of the source to produce a subwoofer output is totally dependent on its design. Generally, you have to 1) tell it you have a sub, 2) define how bass will be routed or shared among your various speakers accordingto their bass-handling capacities, 3) using test tones, set the relative ludness and crossover settings so you have a uniform sound field.


To find a manual, maybe run it by the manufacturer

I have this radio soundstream vir 7000nr. i have a speaker and a amp in my trunk. the only problem is it only plays base. i currently have it plugged in under subwoofer. i dont know where else to plug it...


that deck has front, rear and subwoofer RCA outputs, plug it into front or rear.

additionally, check the amplifier in the trunk to verify that the "crossover" circuit is NOT enabled. if the amps crossover is set to "low pass" or:"LP", then only bass will come out, and if it set to "high pass" or "HP", only highs will come out. you want the crossover on the amp in the trunk set to "off" or "full-range".

Hi,

How to Connect 2 Subwoofers to One Receiver

Subwoofers produce the deep bass sounds that give home theater the realism of being at the movies. A good subwoofer can rattle the walls during action sequences, while adding depth to recorded music and a heightened sense of feeling in the midst of a televised sporting event. Because most home theater receivers are equipped with a single subwoofer jack, connecting a second subwoofer requires a simple audio adapter available at electronics stores. Self-powered subwoofers have their own built-in amplifiers to drive the bass speakers, so they cannot drain power on the main receiver in a system and thus pose no danger to the equipment, even when an extra subwoofer is connected.

Things You'll Need:

Home theater receiver
Y-adapter with RCA jacks on two ends and an RCA plug on the other, available at electronics stores.
2 RCA subwoofer cables
2 subwoofers


Instructions


Plug the Y-adapter into the home theater receiver's "Subwoofer OUT" jack.


Connect an RCA subwoofer cable to each jack on the Y adapter and route the cables to the subwoofers in the room. Because subwoofers deliver an omnidirectional sound, the boxes can be placed anywhere they won't get in the way, but within reach of an electrical outlet..


Plug an RCA cable into the "Sub IN" jack on the back of each subwoofer.


Connect the subwoofers to wall outlets and turn on each unit by pressing the power button, typically located on the back panel.


Adjust the volume and crossover settings on each subwoofer as desired. The crossover adjustment knob tells the subwppfer which low-end frequencies to reproduce from the audio signal, such as a movie on DVD. All frequencies higher than the crossover setting will be transferred to the other speakers connected to the receiver.



Tips & Warnings

Use subwoofers that are closely matched in power, as rated in watts, when using two subwoofers in a home theater setup.

Disconnect the subwoofers from the power supply while making the audio connections.


Have a nice day...

There is no output specific to a subwoofer. What is the correct sequence to do so? Downloaded manual does not help. The Energy sub-woofer has an amp input connection, but no output.


It probably does not need one. I have two receivers that have 5.1 inputs (the .1 is the subwoofer) with jst normal 5 speaker output... none for the subwoofer. That is because the speakers these days almost always have built in crossovers to split the freqs up and send the right freq @ power to the right speaker.

Just buy some speakers and don't worry about it. Look for warranty. Radio Shaft used to have 5 year warranteed speakers -- extremely good for the speaker market. I like bose and I hear infinity is another reasonble priced but well designed brand.

No sound from Behringer 1800xpro subwoofer after connecting to an amplifier


Hi,

Remember that with the switch in Bi-amp mode that the sub takes its signal from pins 2+/2- on the speakon connector.

First of all you need to prove the circuit if you haven't already done so. Check the amplifier and cable by plugging it into another known working speaker, if this works then we have narrowed it down to the cab itself.

It could be a number of things from cabling, to the internal crossover to the driver itself.

The easiest thing to do is switch the active/passive switch at the back, it won't hurt. If it works then there is an issue with the crossover or the associated cabling, if not then take off the crossover panel with the 6 screws, and check for obvious issues here (wires disconnected, signs of burning around the crossover etc).

If this appear ok the you'll need to check the speaker driver itself. You will probably benefit from taking off the grille.

Push evenly on the cone and listen for scraping noises. These are not good signs, if the cone doesn't move this is another bad sign. Finally, either through the back if you can or if not take out the driver. Use a multimeter to check the passive resistance of the driver. It should be around the 6 to 7 ohm mark. An open circuit here is another sign that the speaker needs repair or replacement.
