Can you hook up 2 subs to a mono amp
For a given input voltage, you will get a certain output voltage. Let's say the amp is swinging 8 volts RMS into an eight ohm load. If the impedance is too high, the current goes down but the supplied voltage must increase.
Tue Feb any real dating websites, 8: You use a 70V line. I rather build my own elements from scratch to do what I really want them to do in the first place Her articles have appeared on various print and online publications.
There are 2 sets of 2 8 ohm speakers, resulting in a total impedance of 8 Ohms, only this time, each speaker get 2 watts dissipated across it, for a total power of 8 Watts. You trying to re-write Ohms law? Not even Krell amps keep a perfect power-cube.
The output on the amp is labelled not "8 ohms" but "70 volts" and the speakers come with transformers to tap off of the resulting high-voltage, low-current feed. Mar 21, Posts: Originally posted by Jim Z: Versa Ars Tribunus Angusticlavius Registered: THEN you can get more out.
Why is connecting multiple speakers to one output bad?
Wed Feb 05, 5: In each branch each speaker is dropping four volts. Thu Feb 06, The point was that the usual minor resonances were averaged out by the different physical shapes of the speakers.
No it's better to have a lot of small speakers spread around. For that matter, try it with a battery, or a couple of light bulbs and a wall socket. Thu Feb 06, 9: You can then connect any number of speakers with transformers across the feed as long as the amp power is sufficient for all of them; but it doesn't matter in the slightest if you have fewer than the amp can drive.
An "8 ohm" speaker might have a minimum of 2ohms but a maximum of 30 or more, this is where the ability of an amp to supply current is the limiting factor. Thu Feb 06, 5: And then ther's the fact that to get 3db more output you have to double the power, and it takes 10 db to percieve a doubling to the human ear. Connecting them in parallel most certainly can cause problems for the amp if the result is lower impedance than the amp can safely drive.
In this case it's not very vise to put up two gigantic or even one speakers that can produce a lot of spl. Best regards Bo Eriksson. The load impedance is the same.
Welcome to the Ars OpenForum. Wed Feb 05, 4: Remember that a speaker coil moves through a fixed magnetic field, and is attached to a sprung mass.
Wed Feb 05, 3: This is of course an extreme example. Nov 5, Posts: Above resonance, the speaker will follow an inductor model impedance increases as frequency doesbut around resonance things get really screwy.
