View Full Version : Who knows speakers?

Ive got a couple of old sony component speakers. You know a box with a woofer, tweeter and some other shit.

Well the two 8in woofers fell apart so I picked up some CHEAP 8" woofers.

The speakers I took out were 140w max, 8 ohm impedance. The speakers I bought are 150w max, and 8 ohm impedance. I got everything hooked up and put back together and Im getting barely any sound. You can crank it all the way and its maybe at a normal volume but the sound is terrible.

What gives?

The magnets on the new speakers are WAY bigger than the old speakers, if that makes any difference.

How are you driving them? Amp, stereo?

^^ Need to know more info. Max isnt something really to go by. RMS is the best way to judge what power to put to the speakers usually around half the max. Depending on the way you run the wires the impedance changes.

You need some 4 ohm speakers.

Driven by a sony receiver. Everything worked fine before, sound just crackled because of the foam falling off the speakers.

Some speakers have a lower SPL (speaker sensativity rating), reguiring more power to get the same sound level. I'm guessing the new speaker is less efficient then the old .

You could wire them down, but a head unit is not sufficient to power any sub. For the most part with a good HU your speakers should sound decent. Do you have any speakers lying around like a normal 6.5", if so hook it up and see how it sounds. Your problem more than likely is that your not giving them enough power. If you keep the 8"s and get an amp wire them in parallel form netting you a 4 ohm resistance. So at 4 ohms you would look for an amp at around 150 rms to sufficiently power your speakers.

I thought he was talking about a home speaker.

Shoulda just got a bazooka tube if you want something cheap but with decent bass hits.


Also, you cant just buy speakers and hope they work. Even a cheap system you need thought into.


Can you not find replacements for what you had previously?


And take a pic of how you have it wired in the receiver and post it up here.....you may have it on the wrong output-input.

i think:
-speakers on wrong terminals (rear or center, pos/neg)
-receiver in bad surround mode (echoey)
-receiver in "tape 2" monitor (old EQ loop - not likely)

or
-reciever gone bad

what you did is pretty common, no reason for it not to work

even if the woofers are out of phase, will still be loud.


what other wires did you move around?

You bought speakers from Pay Less Audio, that is pretty much your problem.

Shitty speakers advertize maximum wattage numbers, good speakers use RMS. (root/mean/square) That is how Kraco says 150 watts and cost 29 bucks but Fosgate says 150 watts and cost 300 dollars and they are both technicaly "correct."

At least you aren't out any real money.

Good luck, -Abone.
