Topic: Speaker DIY'ers

Here's the enlarged photo (under scope) of the Euros6 speaker wires that I had replaced with #10 wire. The tiny default wires has black pigmentation an indication of burnt copper. I intentionally placed a glass diode beside the wire to illustrate the comparision of the speaker wires to the 0.5mm diameter of the glass diode's wire.

The resulting sound was far way better than prior to wire replacement and I had more confident in the safety of my gears knowing that the wires could handle better electrical current...

here is a link, it shows carrent carrying capacities of hook-up wires.....http://electriciantraining.tpub.com/14191/css/14191_71.htm

another good reference about wires and cables: http://www.navy-radio.com/manuals/0101-1xx/0101_110-06.pdf

all of these from our friend mr google.....http://www.google.com.ph/search?ix=uca&sourceid=chrome&ie=UTF-8&q=current+carrying+capacities+of+hookup+wires

if you feel you have more peace of mind using wires that can carry 33 amperes, then by all mean go ahead....

[rulesmeister]

At least hindi nasusunog wires ko.. By the way, bakit sobrang big deal sayo kong papalitan ko wires ng speakers ko??? As Ive said earlier, maganda nman result and much safer pa... Cant you mind your own business??? I dont get it why people are so mindful of other people's activities...

Hi Tony,

This got me thinking....... How much current is the power amp delivering to the speakers?

Let's narrow down the limits, say,

1.  For Solid State amps - 25 watts to 100 watts Class AB rated
2.  For Tube amps - 10 watts to 50 watts Class A rated

If there is a guide, then we can optimize the size of the speaker wires without unnecessarily over sizing or under sizing.

Thanks

because you posted in a public forum......

no big deal to me really,and i don't care about your speakers, mine is also a Euros6,  but others(Newbies) might think that using big wires is an ordinary casual thing, it is to them that i address my post to, not to you since you have already made up your mind.....they have other choices too.....

using bigger than nescessary wires should be a conscious decision after getting all the pertinent information are known, and not because someone told them that it is what they should do......

to calculate current into an 8ohm load, I = sqrt(P/8)

so that at 10 watts into 8 ohms results in a current of  1.1 rms amperes;
25watts into 8 ohms results in a current of 1.77 rms amperes;
50 watts into 8 ohms results in a current of 2.5 amps;
100watts into 8ohms results in a current of 3.5 rms amps.....

it doesn't matter tube or ss, the cable has no idea as to type of amp it is connected to....

lenght also comes into consideration, longer runs need bigger size wires than shorter runs....

wha... sunog? san banda yang burnt part na yan? sa terminal, input ng crossover, crossover output to woofer o sa woofer terminal?

[ATJr.]

i forgot to mention, since cables sold locally are more often than not undersized, getting bigger sized cables makes sense, your #10 wire may not even be that....it could be a #16 and you may not know the difference....

parang gusto ko tuloy buksan yung Euros6 ko, pero bakit pa, mahusay namang tumunog.....

[rulesmeister]

@ markcrenz:
Sunog po Sir ung wire na ikakabit sa terminal post sa likod... Ung Euros6 ko last Dec '11 ko lng binili, used sparingly (less than 1 hr/day) on weekdays, and on weekends 2 movies lang kc nagala din naman ako...  Ung setting ko sa Onkyo is between -10db to 0db sa volume..

[JoeyGS]

@ TonyT

Thanks for the informative guide of determining the probable current to be expected in an amplifier/speaker set-up. At least I can have peace of mind and likewise knowing that what I spent for is value for money.

manufacturer's fault. loose connection ang problem, not the wire size per se. may arcing kaya nasunog ang wire. but if replacing the wires entirely gives you satisfaction and peace of mind, well and good. having very curious hands, sabi ko sa sarili ko dati, "if it ain't broke, mod it!" 

[ATJr.]

you are correct mark

pinagdaan ko na rin yan, 

I bought mine in dec. 2010 and still going strong up to now, no desire to tamper with it.....me quality issues ang Dai-Ichi? calling on John, what's going on?

if ever, i will build my own speakers from the ground up......using silver wires, silver solder, polypropylene caps, the works.....

Is there anybody in the house who does enclosures for Full Range drivers? TIA any referals or information will be appreciated.

Guess there ain't none eh? Thanks anyway!

Looks like he isn't interested PM him twice na yata. anyways thanks Sir Nelson

may design plans ka na? patingnan ko sa pinagpagawaan ko ng sansui boxes. sya rin nag-repair ng infinitys

He is seldom online. But may number siya. Anyway:

Ayun oh. Masmadali. Or si MarcoPilyo din pala baka kaya ka niya entertain.

[dvdspike]

Thanks this is very helpful. The design basically one regular bass reflex enclosure and for the other a folded back one. An altenative din is an open type enclosure. I was really hoping AAudio could do this for me since impressed ako sa finish nila and have seen some of the enclosures they did before to other PDVD members, Just too bad they stopped doing this.

Will get in touch when the drivers arrive Sir!

[Stark3]

Share ko lang pala, I just started a "build blog" para sa full range speakers na DIY project ko.


http://www.pinoydvd.com/index.php/topic,162110.0.html

Cheers!

[agsmd793]

my first build!

[juneaki]

I have a Beyma 8 AG/N full range speaker (courtesy of romymartinez).


 I'm planning to build enclosure such as this http://nuebeats.wordpress.com/fullrange-speaker-das-viech/ Since this is my first, i will use muna cheap available materials na nakatambak lang sa bahay. May mga plywood at plyboard na excess from house renovation, will check if enough to build this project.

[juneaki]

Checked my gears, oops kinakalawang na. Time to put them in use.


Started cutting the pieces.


Assembling the speaker boxes.



next time, the finish product.

[audiojunkie]

Looking good.....   

Waiting for the next line of the build.. 

[ndotcom]

Way to go sir Jun. Welcome to the DIY world..be warned mas matindi sa SARS yan pag naumpisahan gusto panay na ang gawa 

[ATJr.]

makabili na rin ng router,power saw, sander atbp....too enticing to diy speakers....

[juneaki]

Thanks mga sirs. And here are my first completed DIY speakers.

[juneaki]

Initial test sounds promising. As expected, per various reviews, ang vocals at acoustic instruments ay lumulutang. Presence of low frequency can also be felt (although not as punchy as from a subwoofer)  but IMHO it's already very good. The good thing not being boomy is hindi nasasapawan yung ibang instrumento kaya made-determine mo ang tunog ng ibang instruments sa music. Sa highs department naman, all i can say is the presence is there but it may need some supplement or some tweaking. What can you guys recommend? BTW, yung likod ns speaker kung mapapansin nyo ay bukas, purposely ginawa kong ganon for future sand filling.

Konting finishing pa, then wood stain using red mahogany then ready na ito. BTW i just use a Yamaha CR 440 na vintage i just bought from vhinx for initial testing. Ipon ipon muna para sa tube amp

[juneaki]

Finally my very first DIY speakers!




Enjoying now the music given by these beymas. Currently listening to Audiophile Voices using Marantz CD 6002 as source and Yamaha CR 440 Stereo Receiver to power the speakers. I want to try these speakers sana with a tube amp pero wala pa ako nun.

you can diy, kaya mo yan....Edrel sells kits....
