Question about Audio Players & Recorders

2 Answers

I have a set of technics SB-5000a speakers. one of them the 10" sub is blown. there is no resistance accross it. the cone is in good shape so i think it is the driver. normally you can unscrew the driver, but in this case i don't think you can. so can i replace it or do i have to get new speakers?

If there's NO resistance, see if the lead running to the cone (coil) has broken.
If so, you might be able to solder it back on and save the speaker.
Sometimes they separate at the terminals, sometimes at the cone.
If it separated at the cone, you may need to peel back a bit of paper to get to the wire underneath, and scrape the enamel coating off the wire so you can solder to it.

Otherwise, it's off to your local audio mart to buy a 10" whoofer at the same or higher wattage and same impedance. Take the old one with you to make sure the screw holes align too! (although that's not 100% essential as you can always drill new pilot holes wherever the screw holes aare....unless the screw holes have a metal insert)

If you did have to peel back some paper to do the repair, reinforce the torn area with toilet paper and fingernail polish. Use several layers as you don't want the movement of the whoofer to rip apart your solder joint or any more of the cone.

You are right about the scratching sound meaning the speaker is blown. The other one by it not playing it could mean the voice coils in it are blown or burnt.The safest way to check the speaker is to connect it to a standard 9 volt battery and listen for a popping noise when you make the connection and look the see if the cone stands up as long as the connection is made n returns to normal and no noises when disconnected from the 9 volt battery. To test this while the sub is plugged in to the amp but out of the box move the cone as far in and as far out as it will go. If it comes on while u hold it on either one of these positions but when released it goes back to not playing then the coils in it are blown or burnt and is no longer any good. As for selling the box its on you, aim anywhere from 2/3 to 1/2 the price you paid for it minus the speakers.

Hello there! I have an 8-10 yr old Bose Accoustimass 10 speaker system connected to an Onkyo TX-DS595 receiver. After moving and setting up my system the Bass Module has almost no base coming out although...


What is your crossover setting set at?
If it is set at 40 HZ, this would explain weak bass; as that Bose system sends ~120HZ down to the sub.

I reccomend checking the crossover setting to 120 or 100; with all speakers to small.

You may need to increase the db setting on your sub as well......

Good Luck.

I have just bought a technics sc-dv290 hi-fi off of my cousin and found out the mid range and the tweeters have blown does anyone know where i could get replacent tweeters and mid-range speakers for it if...


As you probably know, these are the individual model numbers:

SC-DV290 the base unit
SB-DV290 speaker set

Front SB-DV290
Center SB-PC95
Surround SB-PS95

I'd scour Google or eBay for any or all of those models. Orphan speakers appear periodically.

One sub works other doesn't


Disconnect the wire from the speaker and meter it out. check it for a dead short, the meter would read 1..... You can also check the action of the sub by pushing on the center lightly, moving the cone. If it's blown, it will not travel smoothly. If your meter reads ......1 then you've really done it and totally cooked the wire clean thru, thus no resistance. Hope this helps.

Blown?


Typically you will hear a popping sound when the bass hits, or you may not have any sound at all.......If the sub sounds good then your ok.

On a side note, pulling on the cone while the sub is in operation can damage the unit because it cannot move freely under load

Blown solobaric?


how did he messed up? anyways, if u push the cone of the sub down and u hear a sound like "TUN!" its most likely ur sub is irremediably damaged. The cone needs to come up perfectly as a good sub would do. I need to know exactly what ur friend did b.c it is quite weird to mess a good sub by slightly switching cables

The speakers have buzzing sound because of damaged cones.
Over driving speakers, especially with heavy low frequencies, can tear the voice coil away from the cone.
Once damaged, only replacement will help
