    Av receiver str dg700 can I use 6ohm speakers


1 Answer

You should have no problem with 8 ohm speaker with this unit as you would with the 6 ohm speakers. The 6 ohm requirement is only not to go under that value. The only consequence of hooking up higher impedance speakers(8 ohm) to this system is that you will have slightly lower volume than with lower impedance speakers(6 ohm).

I would like to know how to connect speakers to JVC digital theater system TH-C3 and make some sound!

You have to make sure that the ohms of the speakers match the receiver before hooking them up. Look up speaker ohms on you computer and there is a mathimatical formula that will help you figurer the ohms on the speakers. You can use any speaker but, if you do it will damage the receiver.

Difference in ohms

They are probably trying to tell you that if your amplifier calls for a speaker system of 6 ohms or 8 ohms, then, it is not recommended to use a lower speaker system of 4 ohms or less. Why? Because at a lower impedance, the amplifier might not be able to handle the extra current and it might result in a poorer performance or damage to your amplifier. Hope this helps!!

I have the THC C-40 I am interested in purchasing another receiver from this line? Because my DVD tray isn't working on the current system so what other unit might I be able to connect the current...

The chances of another unit hooking to the current speakers is slim to none. While "home-theater-in-a-box" systems like that tend to be inexpensive, the drawback is that they are not compatible with other equipment. According to the Owners Manual, the ONLY unit they are compatible with is the JVC XV-THC50 or XV-THC60. Your best bet is to look for a new system that uses more standardized speakers (five 8 ohm speakers and a subwoofer that has an RCA style input and is powered by its own amp).

My parents are getting rid of their Panasonic SC-HT700. The receiver is shot. The speakers and sub work perfectly fine. I was wondering if I could purchase a used receiver (found the SC-HT930 on ebay) to...

the speakers are 6 ohms, and it will be very difficult to find a receiver that is 6 ohm compatible. most home amps are 8 ohm, and will overheat and burn up when used with 6 ohm speakers.

the subowoofer is 4 ohms, but i am unsure as to whether it is self-powered, or if it is powered by the receiver.

4 ohms is the standard for car audio, and 8 ohms for home audio.

Dead Samsung HTZ310

You can get your unit repaired. (cheapest option) You can hook up the speakers to another unit as long as it will work with the same impedance speakers. Don't hook them up to a receiver that is rated for 8 ohms. Your speakers are 3 ohm. The sub is a passive one, so the replacement receiver will have to work with a passive woofer.

No sound from a Samsung HT-Q40?

It's part of an HTiB (Home Theater in a Box). Get the speakers that it's designed to mate with. HTIB's are not like components. Due to proprietary connectors and who knows what else under the hood, they are not intended to be mixed and matched with other units.

This unit has standard speaker connections so you might be able to find some speakers to hook up to it, but its original speakers were rated at 3-ohms impedance and the spec for the amp is also at 3-ohms. You probably won't blow anything up trying them, but don't expect earth-shattering volume from typical 8-ohm speakers. As the saying goes, individual results will vary.

How exactly did you expect the TV to be the speakers for this thing? It doesn't have an outbound audio connection. TV's are traditionally the part that makes pretty moving pictures while other electronics and speakers take care of the audio end.

If you need the manual, go to, register, find it using >>> Samsung HT-Q40 <<< and download it for free.

Just got JVC SP-PWC50 subwoofer and 2 SP-THC60F front speakers but thats all!!! How can I hook up and power up? What kind of mids and rears can I hook to this system? I have several old Sony and Harmon...

Your intended project sounds interesting. I like the idea of retasking older audio gear into modern multichannel sets. One good reason to use older equipment is that the specs, interfaces and interoperability are standardized so you can tell if/how a given amp and speaker will work together. I do it myself.

It looks to me like you have only part of an HTIB (Home Theater In a Box) system that uses a proprietary 8-pin connector and system cord that would come from the base unit/DVD/receiver (the 'brains', which you don't have). It doesn't appear to be designed for compatibility with other units, say, something that would bring in the 5.1 channel audio via either a digital (SPDIF) cable or via 5 separate RCA audio cables.

This subwoofer is self-powered and also provides amplification to up to 5 other speakers, two of which you have.

Their connection to the sub would be via standard speaker cables, likely the Red and White FRONT spring clips. The output terminals are rated up to 16 ohms so attaching a foreign speaker should not be a problem other than its having unpredictable frequency response.

Besides basic connection and signal processing, the missing DVD/Receiver would also decode and direct the 5.1 channels to the Sub and handle level matching of the channels. Without the 'brains' of the system you'll have to get creative to use the individual parts. The 8-pin input connection will be a big problem unless you're adept at getting inside the unit to figure out where things go before they come out at the speaker terminals. Then you'd have to do some rewiring.

UNDERSTAND THIS: Those connectors are OUTPUTS to speakers, not inputs from an Amplifier. If you hook that up wrong you better have a fire extinguisher handy. Kidding. But it could be bad.

The Front speakers are 3 ohm impedance, clearly designed to be used with the amps inside the Sub so I would be careful in trying to drive them with amps that aren't good at handling low impedances. Give it a try AFTER checking the low impedance tolerance of your amplifiers, but easy on the volume.

I would not expect all of this to be a worthwhile effort unless you just like the challenge. Even if you succeed in making a satisfactory electrical connection with your multichannel source as input there is no way to know if it will sound okay. With all-in-one systems the manufacturer may have matched the speakers up with special amplifiers that are designed for 3-ohm speakers and to shape the sound through active internal equalization in such a way as to produce flat response from non-flat-responding speakers - like Bose does, for example, but at least they tell you that's the case.

The stated spec is 200 watts (RMS) per channel at 3 ohms at 100Hz with 10% Total Harmonic Distortion, a very unusable spec. True and honest watts/channel specs look like, "XX CONTINUOUS watts per channel, all channels driven into 8 ohms (20 Hz - 20 kHz, +0.5 dB, -3 dB less than 0.5 percent THD)".

At only 27 lbs with a Power Consumption of only 160 Watts I'd say the Amps/Sub component of the package is a lightweight, literally and figuratively. Apples and oranges when compared to grown-up audio components. It might get loud but not cleanly. But that's just my opinion.

Here's the Owner's Manual for the entire kit...

There's some discussion of the features, etc, here...

Need to know the OHLMS rating for speakers

Hello! The impendance of the "speakers" does not be "minor" of the "system" . If your system is
3 Ohms, yours speakers must be 3 Omhs too, or 4, 6, 8... Use serial or paralel conectios. Ex.: 3 Ohms +3 Ohms in series = 6 Ohms ---- 3 Ohms +3 Ohms in paralel = 1,5 Ohms.

Sorry about my bad english, I'm just speak in portuguese.
