Cheapest 4 ohms receiver

post #1 of 15
Thread Starter 
What is the cheapest receiver that will accept 4 ohms speakers? I just have a pair of JBL Control 1 monitors and they are rated 4 ohms and I needed a receiver that will work on 4 ohms. I did talk to many people and they said that a 8-16 ohms receiver will work fine but is that true? Since there are alot of receiver that are 8 ohms or higher. Like will the Sherwood RX-4109 will work perfectly fine using just a pair of 4 ohms speakers? I don't need surround sound so just a basic two channel will work.

Most receivers won't fully support 4ohm speakers stable. You will need a separate amp to drive most 4ohm loads properly without clipping and damaging the speaker itself. You can do it, but I would stay away from high volume level.

I thought that if you have it too loud the amp will just get warm but nothin will happen. Maybe the worst case it will goto protection mode but I never heard that the amp could distroy your speakers. I guess it might be possible to brake the receiver from the heat but I don't think the speakers will get any damage from what I heard.

You'll find that there is a lot of confusion regarding dc resistance and ac impedance. No speaker in the world offers a stable load to an amplifier since the impedance is never fixed. Impedance varies with frequency, so you can basically forget the 4 ohm, 8 ohm, etc resistance ratings and buy a quality amplifier with a beefy power supply. In theory, a power amplifier can double it's output as the resistance is halved, but you'll find that's clearly not the case with 95% of the amplifiers out there due to insufficient power supplies.
Edit: Btw, try to buy an amplifier with 2 db of dynamic headroom if possible.

Put them in series with a speaker switch box from Niles.

Impedance and sensitivity are the critical metrics in determining how power hungry a particular speaker will be.
Do not confuse if they will sound good or not with power.
In series Z1 plus Z2 =
In paRallel Z1*Z2 / (Z1 + Z2)=

If you want to know the true current capability of a receiver, check the value of the rail fuses. These fuses are either located near the power transformer and filter capacitors, or on the amplifiers circuit board. There are usually two fuses per channel. (Do not confuse these with the AC line fuse normally found near the power cord.) Check the ampere rating written on the rail fuse. If, for example, each fuse has a 3 amp rating, the amplifier is capable of 6 amps per channel. It's that simple

I had a pair of those running for YEARS for my computer sound powered by a 85wpc Denon Receiver. They will work fine with a quality receiver. I pounded the hell out of them too so no worries there....

Before that I used them for about 5 years as my surround speakers and they were fine there too with 8 ohm mains and center....

I found a receiver that is under $100 and it looks like 4 ohms speakers will work but is this good for basicly around $100?
