Speaker Cable Selection

Friend, in which country you are living?...call any electrical supplier and he will give you the 6mm2 or 10mm2 purpose made cables for speakers. ..but I suggest you recheck the load of speaker as I feel some thing wrong on your cable size mentioned.

Boss,It is not a Sq.mm it is only in mm

calculate the area of cross section of cable using the dia....3.14 x radius square.

radius = Dia/ 2.

I consider the dia as 6 mm ,i calculate it 26 sq.mm ,How can i get the cable as a single core 26 sq.mm or any other combination .if any means please suggest

thank for your support

How did you calculate?...it shall be 28.26 sq.mm., select the next size marked in the cable catalogue.

ok ,What cable i have to select for this Sq.mm,can i get in terms of 6 core ,or 2 core

Thanks in advance

Little wrong - your formula is for the circumference. you need of r*r*3,14 or 3,14* d2/4

nothing wrong....r x r = r square

Thanks, this looks easier.

First my friend, the country I live in is in my address, while yours is still a secret. But the experience I have build up was in France, Belgium, Holland, Germany, England, Spain and Italy. In these (for you 3rd world countries?) they have the screws in line and don't believe all the commercial talk for the "herd". If you feel happy with the "special speaker" wires, buy them, and maybe you can ask also what color of isolation performs best. The speaker coil of the most powerful bass speaker, to mention, and this is not the best one, has less than 1,4 mm2 and that is a 400 Watts speaker of 700 dollars. We repaired THOUSANDS of them. If you read me well, I don't say they are bad. They will handle easy because of the multibrin (many fine wires) and some even are twisted cotton with copper, no wonder they make them that thick. And it is best, when you buy them to start with 10 mm2, because when you make a few short turns with these "super cables" half of your wire inside are already broken before your first note of music. Every performance we had to install and pack more than 3 km of wires. Never we had problems with our wires. As professional note: all professional power boxes have SWITCHCRAFT plugs, made for 2,5 mm2 maximum. When you can measure or hear the difference, let us know.

Dear Guru,

Please send your reply to real forum thread and not to me.

Check here! Are these speakers the size of desks?

Seems extremely oversized. Google could have answered much quicker.

Dear friends Please advise me ,I want to connect to bosch make horn speaker ,In the catalogue of the bosch make speaker they specifies the cable must be 6 mm to 10 mm dia ,so please give me the suggestion of cable matches with above mentioned dia in sq.mm Regards Kaphaka Your Message: I think the suggested cable size include the insulation, 6mm to 10 mm diameter insulated cable?? Copper conductors inside cable will be much smaller in diameter. Solid conductors versus stranded also do have different electrical characteristics. vsar

6mm diameter cable will be sufficient to start a medium sized truck.

10 mm will be sufficient to start a large truck. Perhaps you have a dimension wrong.

Is there a decimal point missing?

Determining wire size by the outside diameter is not good, as a 7mm wire used for automotive ignition system would have a smaller cross section of conductor than a 7mm welding cable would. Perhaps you could give us the model of the Bosch speaker, and we could be of more assistance.

For audi applications I think the suggested cable size included the insulation, 6mm to 10 mm diameter insulated cable?? Copper conductors inside cable will be much smaller in diameter. Solid conductors versus stranded also do have different electrical characteristics. vsar

I think the size in dia mentioned is the cable termination connector size in the speaker. Our friend is misleading us everybody.

TRUTH and LIES about speaker wires.

Dear Kaphaka

I do not know a bosch make horn speaker. I know what a horn speaker is, and they can mean 2 things, based on the horn like construction - mostly exponentially enveloped - with at the base a membrane, when a Midrange Speaker or a Tweeter - the typical music source (as seen with old gramophones) -

For public address or weatherproof horns outside a similar construction is used for the whole audio spectrum, typically with low performance in the low frequencies and the highest frequencies,

If you want more specifics about it, ask it, otherwise I write 10 pages full.

THE HORN

- tin, aluminium, steel, plastic and sometimes also layered and modeled plywood. is not important, it is the driver membrane.

These come or in 4,8,18,32 ohms and also for the full range horns for longer distances in 75 or 100 Volts line. (which is nothing more than the same membrane with a impedance transformer)

HORNS ARE USED FOR THE EFFICIENCY, DIRECTIVITY, OR ACOUSTICAL OUTPUT LEVEL.

And yes, the idea dates from 50 and more years ago when it was difficult and expensive to build a powerful amplifier.

A good worked out horn in front of tour speaker or membrane can give you a gain of 3dB (decibel) or more. 3dB is the same acoustical output as with an amplifier double the output power.

This is also true for bass horn speakers. Famous models are:

Klipschorn , JBL disco 100 - 200 - 400, Altec lansing A7, and the master of LOW HORNS is the EARTHQUAKE. All these big boxes were top performers with relatively moderate power speakers. (100- 200 Watts)

If BOSE is what you mean - they take advantage of the high power amplifiers and correct what is not sounding naturally "electronically" with a multi band equalizer.

THE WIRES:

I can tell that I have a well experienced EAR, and all the commercial talk about multi-core, and other fancy wires is just to sell a cable for a lot of money. They go even for gold and platinum contacts, and more.

They need to sell - that's all.

I did many sound recordings, Rock. Pop, Disco and Classical Symphonic. I did PA for big names with sound equipment of 50.000 Watts plus in the open.

And the largest SECTION OF WIRE FOR A 350 WATT BASS SPEAKER LINE 20 meter long was 4 square millimeter souple wire, like for a heavy electric grass mower.

MEDIUM SPEAKER LINE Max 2,5 mm2.

EVERYTHING THICKER IS THROWING YOUR MONEY AWAY

You will hear arguments and the closest considerable is the damping factor of the system. (when they are honest they will tell you that the amplifier takes care of this and the wire comes 3rd, after the speaker)
