New Receiver + New Woofer under $2000?

Hello all,

It has been a while, since I have to purchase a new system. Helping my friend who just bought a house with 13 built in speakers. They are all JBL BRAND ceiling speakers.

5 speakers in the living room where the tv is..
2 speakers in the room 1
2 speakers in the room 2
2 speakers in the room 3
2 speakers in the room 4

since the previous owner couldn't take out the speakers....they took everything else away...but left us with a monster 6 way speaker selector.

after careful discussion, my friend needs to have multi zone and probably wouldnt power on all 13 speakers at the same time. Also want a woofer where the 5 speakers are.

I was thinking what is between Marantz 7005 and Yamaha RX-667? Because my friend is not going to get a 3D TV........

Please give me some suggestions?

thanks in advance.

I assume the remote speaker switch is an "impedance protecting" model, but you need to make sure before you try hooking 4 pairs of speakers up in parallel to a receiver's zone B outputs.

How big is the room that will be the 5.1 surround system ? What are the owners likes and dislikes as to the size and enclosure finish of the powered subwoofer ? Is there a convienient AC power outlet near the preferred location of the subwoofer ? Where does he plan to put a largish rectangular "box" ?

wow.. I want to say thank you first for pointing out all these things. I am quiet a newbie since I only worked with 5.1 systems before.

now I am scratching my head......How do I make sure the speakers are impedance?

About the Room for 5.1 system, I will have to go measure it and I have to scout the place to see where to put the woofer.

Since the previous owner really likes the sound system they had, they build a cabinet for the equipment, so that's where I will be putting the receiver.

each of the installed speakers will have a "rated average impedance" and it will probably be 8 ohms, or occasionally, 4 ohms. The problem begins when you wire a group of speakers "in parallel" because in an AC circuit the combined impedance of the connected speakers can drop. Two 8 ohm impedance speakers in parallel looks like one 4 ohm load.

If the load impedance drops too low, the receiver's amplifiers can attempt to push far too much power to the speakers and the amplifiers will fail (let the magic blue smoke out ! ).

An "impedance protected switch" has the circuitry to combine all the speakers attached to the switch and never let the impedance seen by the receiver drop below 4 ohms.

So in easy terms, look up the model of the switch and see if it is impedance matched.:rolleyes:

I am almost certain it will be since the previous owner used it.
