How does the M200 handle a 4 Ohm load (providing 300W). Anyone have one connected this way? What has been the results?

My DefTech's are rated @ 4 to 8 ohms, with most benchtests showing they are around 5 ohms most of the time.

I think they are exemplory amplifiers. And I think they can handle any load with ease. I listened to music and movies at reference levels at times and there was never any harshness.

I dont know if the speakers or preamp are contributors to that, but the 200's are a fine amplifier. I wouldnt worry about 4 ohm loads. Then again, I wouldnt run a speaker thats rated at 4 ohms, for 10 hours straight, on a hot summer day. Other then that, no need to worry

Play it LoUd!!

I am using the Phase Technology Teatro 6.5 as my center channel. They are kind of small and don't keep up with the rest of my system. I was thinking of getting another one and running them in parallel to a M200 for a total of 4 ohm load.

56 Hz - 20,000 Hz +/- 3 dB

Sensitivity: 90dB
Midrange/Woofer: 5 ¼" vapor deposited titanium driver plus 5 ¼" passive bass radiator with butyl rubber surrounds.
Tweeter: 1" soft dome
Outside Dimensions: 18"H x 7W" x 8 ¼"D

Since I'm thinking of upgrading to the Model 200 M-Block this seems like an appropriate thread to ask this question.

I'm using a Yamaha RX-V995 receiver. There's an "Impedance Selector" switch on the back of this receiver with two position options:

Upper Position
Center speaker - The impedance of the speaker must be 4 ohms or higher. Rear - The impedance of each speaker must be 6 ohms or higher. Main - The impedance of each speaker must be 4 ohms or higher.

OR

Lower Position
Center speaker - The impedance of the speaker must be 8 ohms or higher. Rear - The impedance of each speaker must be 8 ohms or higher. Main - The impedance of each speaker must be 8 ohms or higher.

There's nothing on the back of the Outlaw 200 similar to this switch. Does the 200 not care about the speaker's impedance? I wonder why my receiver needs to be configured according to the speakers impedance and the 200 doesn't?

Could be wrong and someone here could explain the 'tech' behind it. But an inelegant explanation as I have understood inmpedence.
When you see an 'inpedence' switch on a receiver, - beware. Be careful not to overpush the unit. The switch is there to protect the recievers amps from overheating and overextending itself, (and overheating all your internals) so the unit won't blow up and go into protect mode or fry.

When you have plenty of power (200 x 1) beyond reasonable spec checking on needed watts vs Speaker sensititivity etc. This switch is not necssary to protect your amplifaction from over extending itself. And particuarly with monoblocks your heat dispatation hopefully (depending on your metod of stacking) would not endanger the 'pre' part of your system.

Lena is correct. That switch is there to keep the amplifier from overextending it'self. It speaks volumes about the amplifier (receiver) with such switches, none of it good. Too small power supplies, lack of sufficient output transistors and heatsinking are some of the cost cutting measures on these "units". An adequately designed power amp does not need such switches, and should take lower impedances in stride, ideally doubling it's power output for each halving of load impedance (up to a certain point!)

Thanks for the interesting input. Luckily I haven't experienced any problems to date. But since I'm a guy and it's the nature of the hobby I'm always looking for that next best component or speakers or etc.

then you have the sick just like the rest of us. (what next itis).

Yeah, it's true, I'm infected. But not as bad as some (merc).

One of the funnier quotes I've seen was on another website (hometheatertalk):

"This is never going to end, is it?"
-My girlfriend, her first words upon seeing my new Amp and realizing the full extent of my HT (home theater) addiction.

To Soundhound:

I would like to point out that your point about impedance switches "It speaks volumes ... none of it good" also applies to the 1050 which has just such a switch.
