What amplifier do I need for 8 ohm speakers?
What size amp do I need for 2 100 watt speakers?
What amplifier do I need for 4 ohm speakers?
With a 2 ohm speaker, the maximum output power will be 550 watts.
How many watts is a 2 ohm speaker?
I responded to the other thread you started but the short answer is: run both cabs from the 2 ohm jacks. As to your second question, the answer is yes. If 4 ohms is the minimum recommended load, don’t hook up 2.6. I have an SWR sm-900 amplifier, a 4 ohm and an 8 ohm speaker.
Although a particular loudspeaker may be rated for 4 ohms (nom), it may actually provide a more stable load for an amp to drive than another speaker rated at 8 ohms. A well designed 4 ohm speaker system will usually present a more ideal load to an amp than a poorly designed 8 ohm speaker.
For example: four 4-ohm speakers wired in parallel have a total impedance of 1 ohm. Subwoofer manufacturers make subs with dual voice coils (DVC) to take advantage of this difference in wiring schemes, so the user has more freedom of system design. A DVC 4-ohm sub can be wired into a system as a 2-ohm or as an 8-ohm load.
For example, if the amplifier is producing 20 Volts at the output terminals, Ohms law (R=V/I) tells us that there are 50 watts being fed into an 8 Ohm speaker (watts equal voltage squared divided by impedance).
One Dual Voice Coil Speaker in Series. 1 Dual–8 Ohm Subwoofer: 16 Ohms. 2 Dual-6 Ohm Subwoofer: 12 Ohms. 3 Dual–4 Ohm Subwoofer: 8 Ohms. 4 Dual–2 Ohm Subwoofer: 4 Ohms. 5 Dual–1.5 Ohm Subwoofer: 3 Ohms.
How do I calculate speaker Ohms and Watts?
Dual Voice Coils give you even more wiring options Subwoofer manufacturers make subs with dual voice coils (DVC) to take advantage of this difference in wiring schemes, so the user has more freedom of system design. A DVC 4-ohm sub can be wired into a system as a 2-ohm or as an 8-ohm load.
Can I hook up 8 ohm speakers to a 2 ohm amplifier?
Your installer will need to wire both voice coils to your amplifier to ensure that the subwoofer maintains its power rating and functions the way the manufacturer designed it.
This means a speaker with a “nominal impedance” of 8 ohms and a program power rating of 350 watts will require an amplifier that can produce 700 watts into an 8-ohm load. For a stereo pair of speakers, the amplifier should be rated at 700 watts per channel into 8 ohms.
Matching Amps to Speakers This means a speaker with a “nominal impedance” of 8 ohms and a program power rating of 350 watts will require an amplifier that can produce 700 watts into an 8-ohm load. For a stereo pair of speakers, the amplifier should be rated at 700 watts per channel into 8 ohms.
