speaker system need help

space2000 · 27th May 2008, 02:03 AM

Hi DX and others,

i am thinking to make a diy speaker system.

here can’t find 16 or 8 ohms 12” or 16” inch woofer…..only can find 6ohms or 4 ohms…

As I am operating precision I amp, should I use 4ohms speaker for this amp? My current speaker system is 8ohms, it’s got two pcs 8inch woofer.

Is there anyway I can make two 4ohms into 8 ohms speaker?

Thank you.

Yeah man, hook them up in series........2 speakers of 4 ohms hooked up in series will create 8 ohms.....If you were to hook them up in parallel, they would then be 2 ohms.....Omni

8 ohm speaker will require a higher volume level setting to be driven up to an equal Sound Pressure Level than a 4 ohm.....In other words, a 4 ohm driver will play at louder levels than an 8 ohm driver will for a given volume level setting on the amplifier.....4 ohm driver will draw more power from the amplifier than an 8 ohm driver, creating a larger load for the amplifier.....I won't comment on the differences of sound quality between the two, because I have only worked with 8 ohm drivers in my home systems, and typically 4 ohms for automobile sound (which is an entirely different story).........I prefer to give my amp a break, and not use 4 ohm systems for home stereo systems......I don't know enough about the subject of 4 ohm systems for home set ups, but personally feel, that for me, I don't want to cause a lot of strain on my amplifier, so I typically stay with an 8 ohm setup.....which can be achieved for example, if you have two 4 ohm woofers per side which are wired in series, thereby creating an 8 ohm load on the amplifier.......Then, I can use an 8 ohm midrange and a 6 or 8 ohm tweeter, and design a relatively safe speaker system for my amplifier.....There may be others on this forum who have experience in 4 ohm setups, and your thread is fairly new, so maybe some of those guys will chime in here...........Respectfully.............Omni
