Sir yung textile dome tweeter ng wharfedale speaker ko nangangamoy sunog at saka mahina siyang tumunog than the other channel. Pero hindi naman siya totally dead..mahina lang yung sound output niya..Ano po kaya ang problema at pwede pa kayang maayos to? Sinubokan ko na palitan ng same specs na tweeter which is from my center channel speaker..pero mahina pa rin..

Sir,

Good Morning.  Part ng voice coil ng tweeter mo is nasunog kaya mahina ang tunog.  I recommend voice coil rewinding.


Thanks,

Benedict

Sir, I have a Wharfedale 6.5" speaker na mahina tumunog kesa sa isang channel (bought it pre-owned), upon inspecting the driver closely it has traces that it was repaired already that the previous owner did not tell me, but recommended a voice coil replacement instead.

Anyway, im planning to bring it to your place this coming Saturday, will it be possible if you can restore the voice coil and bring back to its (near) original state? And should i also bring the other speaker for reference as well?

BTW, pa-pm na din kung magkano magagastos ko dito. Thanks!

Sir p@rekuy,

Yes, to be sure please bring the other speaker for reference. Charge is same as voice coil rewind for 6" speaker.


Thanks,

Good day to you sir Ben. Itong speakers ko po may loud "Popping Sound" everytime I switch it OFF, tanong ko lang po sana kung nare-repair pa ba 'tong ganitong problema? Thanks and more power!

Sir,

I think its because of the amp of your sub and not the speaker.  Some subs emit "thud" sounds when switching on or ff.  Ganyan po talaga yan dahil sa design ng amp.

PS - Parang may nabasa na akong ganyang topic dito. Try to seach and back read dito sa childboard.

Thanks.

[Razorblade-Suitcase]

^I see. Thanks a lot for the info sir! Mabuhay po kayo!

Good day Doc!

Here's the deal...

I have a JBL 1800Gti 18" subwoofer (circa 1990s) that has been in storage for years. Unfortunately, the one who stored it for me placed magazines and books on the cone. Ouch! When I finanlly realized how it was stored, it was too late as the cone was resting at the lowest postion and did not pop back up when I took the magazines off.  

I wanted to ask if it would return to the proper position if I hooked it up to an amp and used it or is this up for repair?

If the latter, what parts of the speaker would need repairing/replacing and how much would that cost?

Btw, I'm not sure what the current suspension material is,  I don't think it is either rubber nor foam as it has 3 to 4 ridges on it and feels like paper that has been coated. Anyhow, I notice that you did not have 18" suspensions on your price list. What are my options if ever the suspension needs replacement?

Crossing my fingers for a positive diagnosis!

Thanks Doc!

Sir Maximo,

Good Morning. Based on what you posted, the problem is the part called the spider.  

"The spider is that yellowish/brown corrugated disk attached to the cone and voice coil at the base of the cone. It's major responsibility is to provide a restoring force, or spring, to the cone so that the cone can return to its normal resting position after being moved by the voice coil in response to an input signal. The spider is normally made of a bakelized or phenolicized fabric and has several corrugations."

Pressed to long makes it sink from its normal position.

The suspension your speaker has is made of cloth.  If the suspension needs replacement (which i doubt it needs to be replaced, unless damaged) we'll try to find a similar one.

Thanks,

Benedict

Thanks Doc Benedict.

That diagnosis doesn't sound that bad. =)

Could you give me a ball park figure on how much it would cost to replace the spider?

Thanks sir.

Good day doc,

Was sorting out my bodega stuff and i found this SB-5 x 2 units.   'twas my dad's (R.I.P.+) and for sentimental reasons I am  thinking of restoring the finish assuming it can still be repaired , if the speaker electronics are within economical repair and only if it will work as a speaker for an AVR.

I have tried plugging it to my cheap karaoke amp. Wired it to test and sound is still awesome! right works well,  left needs fixing(tweeter only works), at when you move the knobs may static ka marinig


Need my Technics SB-5 checked, i have 2 and one is functionally working but may require some case repair but the other yung tweeter lang nag work.



Q: Can i use it as a temp front sa AVR?
Q: Is it worth restoring Technics SB-5?



TIA

Sir,

Yes we can. Depende po sa size/diameter ng speaker.  Paki tignan po sa 1st post ko yung rate (under voice coil rewind).

Salamat po.

My answer to both of your question is YES.
