Loud Speaker?

--- Quote from: ChrisGreece52 on May 28, 2013, 09:32:44 am ---Hello i got 2 8 watt 14 ohm 2" speakers and i am wondering if i can increase the max volume (like overcklocking the speaker) with any kind of way ....
This may sound crazy but it may be possible i think.
Also could i use both speakers as one (by connecting them in parallel or in series ?)

Use the speaker as a driver for a horn speaker.

--- Quote ---The main advantage of horn loudspeakers is they are more efficient; they can typically produce 10 times more sound power than a cone speaker from a given amplifier output. Therefore horns are widely used in public address systems, megaphones, and sound systems for large venues like theaters, auditoriums, and sports stadiums.

But not for a bass guitar :-) Horn speakers are used for midrange and high frequencies.

Ill be using it with my bass guitar and i am planning on using small to medium sized speakers with a wooden box so it amplifies the sound.

With 2" speakers you'll get a very lousy bass. If you got a proper datasheet for the speakers we could calculate the wooden cases volume required to improve bass, but I doubt it would help much. Better go for 8" speakers and design the amp for about 25W at least.

I dont want something loud because i will mostly use my pc speaker system (25watt RMS).

So i wont do it because i will use frequencies as low as 30 HZ.

That transformer in the pictures is very small, it's 300mA maximum. You can't do shit with it when it comes to audio amplifiers.
Look for something in the range of 18v (either with center tap or two 9v secondary windings) or a 24v transformer.

The transformer in the picture is a 500mah 9 volt one but i will need more info about connecting it in parallel so i can increase the voltage
Also sorry about the huge quote and sorry for my late response i just had time to read and answer.
