You can check with Classe they should be able to answer your questions. I used a Classe CAV150 for about 4 years in a home theater system with all Thiel speakers and had no problems at all. I checked with classe prior to purchase and made sure that 4 to 3 ohm loads were ok. I did not ask about 2 ohm load because thiels do not go that low. Good Luck
Can CLASSE Amps Drive.......
....a continous 2Ohm load without any problem/concern? To Classe owners out there, would you kindly share your valuable experienced.
I am looking at the CAV series (75 or 150) multi channel amp to do duty on this http://www.linkwitzlab.com/orion_us.htmfor HT and 2 channel.
The required amp for this is 6-CH minimum. Most owners use 8 channels which makes individual channel driving a 4 Ohm load each. Now for 6 channel, 4 will be driving a nominal 4 Ohm load independently while two of the channels will see a 2 OHM load continously (Peerless sub drivers X 2 connected in parallel).
I am considering the Classe because of budget contraints (they are now available at around $1800 used!). Besides, the CAV 150 Six-Channel amp for example at 150 wpc(8 Ohms) continous as rated by the manufacturer will double up at 4 Ohm load, so it means that it is safe to say that its capacity is about 1.8 kW at 4 Ohms and with say a factor of safety of about 30% (which is a lot of room) will give me aroun 1.2 to 1.3 kW. Assuming that I am using 50W for the tweeter and mid (that must be very loud already!) each, which at 4 Ohms becomes 100w x 4 is 400 watts. From the estimated available power above, I still have around 900W at 4. So that will be 450 per of two which seems to be more than enough to drive a 2 Ohm load. Does that sound right to you?
Comments please!
