What Speaker(s) i need for Guitar Amp?

Morbid · 28th June 2004, 03:17 PM

Hi, I know there's lot of kinds of speakers and compoments, and I
want to build a new guitar amp....the amp is ok....but i need to build the box and the speaker...
now, i know the speaker for guitar amp is big but it isnt a woofer...
it combines the frequency range of the high-mid-low notes
so what speaker it should be ? and what box to build?
thank you,
Chen.

The celestion speakers almost seem kinda standard in guitar speakers.
You will find them in countless and highly regarded combos, stacks.
Not sure about the exact model numbers but if I recall right one of them was "12G".
Will look it up.

Unsurprisingly you need a guitar speaker, in a sealed or open
backed cabinet, the lower Qts drivers suiting sealed, the higher
Qts ones open backed. Fs is usually around 70 to 80Hz.

Look out for Eminence speakers!
Very good quality for a reasonable price, and they have a big range satisfying nearly every taste of sound.
http://www.eminence.com
BTW: There are many other good guitar speakers out there. Jensen, JBL, Celestion (Greenbacks, G12H100, Vintage 30), Fane, they all make a range of good speakers, but Eminnence seems to have an unbeatable price/performance ratio.
I personally use the predecessor of the Legend V12, a very good/versatile guitar speaker.
If possible: Check guitar speakers by yourself, with your own ears. They are a part of your instrument, and I think you would'nt buy a guitar without playing it before...

Best regards,

Oh, I forgot something to mention:
The speaker cabinet depends on your taste, too (obviously

).

Simple rules:
- Open cabinet, fewer speakers -> lesser lows (i.e. most combo-amps)
- closed cabinet, more speakers -> fatter sound (e.g. classic 4x12" Marshall-cabinet)

Resulting rule of thumb: Put the speaker with the best mids and highs (satisfying _your_ taste) in the cabinet which fits your needs in the low-end.
... an algorythm for calculating the best cabinet for your (or any other guitarist's) needs is yet unknown ...

Have fun!

I'd go for massive overkill in the power rating too, especially if you play loud - it's easy to blow up speakers with a guitar

a lot of the Celestions/ jensen 60s reissues stil have the low 60s power ratings too...

What kind of dispersion do you need? 360 degrees? 180? Less?

Morbid · 29th June 2004, 10:16 AM

First of all thank you guys for the information....
the website Vek gave me look intersting....

and whats dispersion ?

Just a note :

The power rating of the speaker should be double that
of the amplifier, if you do this it should be very reliable.

As stated above there is a huge range available :

Open backed is preferred for a lead style of guitar playing
and a lighter style of rythym playing, e.g. VOX AC30, whilst
closed back is preferred for a chunkier and heavier sound.
