Question about JBL Venue SUB12 Subwoofer

1 Answer

My sub-woofer keeps clicking between "stand-by" and "on" . This usually happens after about an hour or so of use. I have replaced the audio cable, and have had this in for service, still the problem persists. I even replaced the reciever, thinking that the problem was there. HELP!!!!

Hi.
There is a thermal safety sensor inside your sub, preventing it from overheating.

This is what is causing it to kick of after an hour or so.

Now, if you live in the U>S>, then take the sub to Fry's or BestBuy, and they can replace the thermal unit, as it sounds like it is what is actually going out in your sub.

I'm just surprised that they didn't fix it right when they had it in for service.

The only other thing I can think of right off hand is that there may be a resistor, or transistor that is faulty.

It has to get hot before those parts tend to show damage, that's why I say it might even possibly be them.

After all, your sub is a 500 watt sub, that's pretty high power, and has to create a tremendous amount of heat inside the sub box.

I hope that I have given you some ideas as to where the problem might actually lie, and that it helps you when going for repairs.

I hope I helped you out some today, and good luck.

Sa-he70 subwoofer no sound


Hi, The sub woofer does have a level control, is this indicating that the level is moving?
Woofers are a power device and usually active, i.e. needing a power amplifier to feed them. If this is a stand alone speaker though try using an AA battery on the wires. you should here a click when you touch a battery on it. If you can see the cone move out then the wire that goes to the + of the battery is the red or positive wire, if not turn the battery around. do not use anything higher that AA i.e.1.5V If you hear a click the speaker is ok and the amplifier is either faulty or not turned up.

Box specs and airspace for 8 inch subwoofers


<span>Regardless of your wattage rating on your sub woofer, sub woofers</span> differ in only one way. You get an "Open Air" and a "Closed air" <span>Sub woofer</span>, That being said, you'll have to check on your magnet which one you have, to make the boxes for that particular sub woofer. If it is an "Open air" <span>Sub woofer</span>, you should see a hole with "wire mesh" or "metal grid" in the center, at the back of the magnet. If it is a "Closed air", the magnet will be solid with no hole whatsoever.<br /><br />If it is a "Open air" sub, your boxes should always be sealed with silicone sealant, and no ports are to be cut in your box.<br /><br />Regarding the "Closed air" <span>sub woofers</span>, you should have 2 ports cot in the corners of the boxes just below your sub on the face of the box, and the port sizes should be around 50mm in diameter. Get yourself some 50mm PVC drain piping to use as ports. Firstlycut yourself a 100mm piece and insert flush with the front of the box. Test your sound. then try a 150mm piecs and test again. You should start with a 100mm long piece in the one box and add 50mm increments to "tune" the port up to 250mm, depending on the frequency of bass you require. Carry on testing the sound on each increment until you find the sound you want, Then silicone the port to the box for permanent fixing.<br /><br />On a 15 inch <span>Sub woofer</span> ranging between 80Hz and 100Hz, the ample box size required should be a box of 9 inches high, x 9 inches wide, x 9 inches deep. Or 400mm high, x 400mm wide, x 400mm deep. <br />Enjoy! <br />

What's the best way to hook up my jl audio 13" w 7 sub to my jl audio 1000/1 amp


the best way? hmm. i would start off with some wire. Keep in mind that you will need to separate the positive (usually red or has a stripe or marking on it) from the negative (Black usually is the common color for this wire) and hook the up according to your amps positive and negative hook ups / terminals following your sub-woofers terminals. then depending on your sub woofers Voice coils (Duel or single voice coils) yours are duel or quad coils but i\'m sure they are duel (2 of each positive and negative equaling a total of 4 posts on each sub-woofer). figure out your amps ohm load handling and does your amp run hot (1,2 or 4 ohm stable some are even less like 0.5 or lower) i would run at a 1 or 2 ohm load as that is usually standard on 1 channel amps. make sure to check your wiring and if your not sure about ohm loads just Google wiring for sub-woofer ohm loads such as 0.5 ohm, 1 ohm, 2 ohm or 4 ohm loads. also make sure your box is not sealed do to the fact they are siht and cant produce sound like a vented / ported enclosure keep the size as big as you can fit in your car or truck the bigger the better. i had one 8\'\' sony sub pounding like a 15\'\' sub real loud . Also MDF particle board is garbage it causes port noise and absorbs water

What would happen if i plug a 8ohm speaker into my car's stock radio?


Car stereos are 8 ohm as well so from that stand point not a problem. You cannot just hook these up as you are proposing though. You will need to get an amplifier with a left and right out and a separate channel for the sub itself. There are multiple ways to hook this in but you need to learn more about impedance. There are a couple of good sites online for understanding car audio. I would check them out starting with parallel circuits vs series circuits.

I need a wiring diagram from car stereo to 2 x 6 " x 9 " and a sub woofer please


You can connect the two 6x9 speakers to the two individual left and right outputs of the car stereo.
Connect each of the left and right channel with the correct polarity . Now the Sub-woofer requires an amplifier to be connected separately and so you need to use the car stereo to be linked to a sub woofer amp which powers the sub woofer.

I have 3 10" clarion


If your sub woofers are DVC 4OHM: Connecting three together in Parallel/Parallel would make your amplifier run a 0.67OHM load or if connected Series/Parallel then you would have a 2.67OHM load. If your sub woofers are DVC 2OHM: Connecting three together in Parallel/Parallel would make your amplifier run a 0.36OHM load or if connected Seies/Parallel then you would have a 1.67OHM load and Series/Series a 12OHM load. So if your sub woofers are really DVC, it would be impossible that your amp would be playing 4OHM. The numbers just don't add up. There are amplifiers out there that can deal with 0.50OHM loads but expect them to be on the pricey side, but fairly so, because mostly higher end brands tend to manufacture them and are usually pretty good. Remove 1 of the sub woofers. If i knew what the subs where 4 or 2 OHM DVC and what amplifier you are using i would tell you how to connect them for the best possible result. hope this helps dreamsystems

Sr7200 LFE (sub woofer) output stopped working


Chances are if The Receiver only has sound in Stereo Direct Mode and all surround modes and Sub out are Inop the DSP (Digital Signal Processing) Card is most likey defective. These boards are not available from marantz (D&M Holdings) and must be Component level repaired which usually is not cheap. If Only the Sub out is not working check setup to be sure sub woofer is set for on. Also If On Screen setup menu does not appear on video monitor Unit may need to be Reset manually which entails discharging a Capaitor on main P.C.B Contact kstahl65@att.net for details
