Bose Model 101 Speakers (4ohm) - Can I use them on 8 ohm s..

Archived from groups: rec.audio.tech (More info?)

The higher end amplifiers, especially many of the studio grade ones can use
4 ohms without any problems. The design for 4 ohm operation has to have a
higher current loading capability.

It is best to be careful when using 4 ohm speakers. If the amplifier is not
rated for 4 ohms, you will be having it serviced very shortly, especially if
you like to play it at moderate to loud volume settings. Very careful follow
the instructions for the amplifier when connecting speakers.

I have 2 pair of Bose Model 101 Music Monitor Speakers (4 ohm - 60
watts max) that I would like to use on my home theater system.

I have 2 receivers - Sony STR-DE595 and Sony STR-DE845 (Both are 100
per channel)

I an currently using the Bose 101's on the DE595 as front and rear L&R
( I hooked them up before I noticed that the receiver specifies 8 ohm
speakers). To me, they sound pretty darn good and so far I have had
no problems.

I am going to switch to the DE845 receiver (bought second-hand)
because it seems to have more features. However, in reading the
manual, it clearly specifies 8 ohm speakers but you can use 4 ohm
speakers on the front R-L if you select 4 ohm on the 4-8 ohm selector
switch on the back of the receiver. The manual says not to use 4 ohm
speakers for R-L rear.

My question is, am I risking damage to either the 4 ohm speakers or
the receivers if I go ahead and use them on both front and rear?

Which also begs the question, why would Bose make the Model 101
speakers 4 ohms when most all of the stereo systems I've seen specify
8 ohms?

Thanks very much for any help!

Put 2 Bose IN SERIES on each front channel of the DE845. (4 Ohms in
series with 4 Ohms is 8 Ohms--are 8 Ohms?). Sell the 595, buy 2 8 Ohm
speakers for the rear channels.

Why would Bose make them 4 Ohm to begin with? Well, if they're the
kind of Bose speakers that use a lot of identical drivers and heavy EQ
to get decent lows and highs out of them, they need more power to be
as loud as other speakers so maybe they're trying to double the Watts
by halving the impedence.
