I recently emailed Denon's Tech Dept, to ask about the capability of the 3805 & 4ohm speakers in general, particularly the Lsi25,15, & Lsi9. Here is the email.

Hello,
Can the Denon avr-3805 comfortably power a 5.1 Speaker system that consists of only 4ohm speakers. I have heard different opinions & was wondering what your opinion was. Thank You, Eric

DENON's response
Hi,
We do not recommend using 4 ohm speakers with any of our units. It may cause the unit to overheat and shut down at higher volumes. Please use 6 ohm or higher.


I need some feedback from people who own a denon 3805 & some Lsi polks. I have heard that the Lsi Polks actually run closer to 6 ohms in "real world" use. I get the feeling denon responded in that way due to warranty issues. An old word called Liability. I want to get a denon 3805 with an lsi25,15,9...not sure yet...lsic,lsifx,lsiw... Everyones input is welcome especially people who actually own the equipment in Question. Thank You, Eric

    Do you mind if I ask you how you came to that conclusion. What receiver do you reccommend? $1000 or less.

    LSi's are also some of the "higher impedence" 4ohm speakers. Looking at the impedence graphs, the speakers should be labelled as 6 ohm, not four. As far as the 15 and 25, since those have powered woofs, they should be very easy to drive. I'll send you a link with the impedence curve of the 9's when I find it again.

    Charts for LSi9

    If you want a new receiver with warranty, I would get H/K AVR7200. For a receiver it has good current, 70A. I don't know if I would want to run the 15's but 7's and 9's should have no problem mating with it. You should consider used amps.
