weak zone

[CDC]

I installed a Sherwood 105w/ch. reciever on a zoned audio condo. There are 4 pairs of speakers and 2 dual tweeter speakers installed. all speakers are proficients. the outdoor dual tweeter speaker has super low volume and if you turn it up all the way it will trip the protection on the amp. All volume controls (russound altx) have the jumpers set correctly. WTF, what gives? Thanks. CDC

How long is the wire run to outside and what gauge are you using?

So, that's 5 pairs of speakers?

I'm guessing the dip switches on the impedance matching volume controls aren't set correctly, check again.

Try each speaker pair one at a time, then add a pair at a time.

Maybe someone smarter will chime in.

Jay, "How long is the wire run to outside and what gauge are you using?" The DT speaker we are having trouble with was pulled in 16ga. wire and is probably about 120' long.

Neurorad, we checked the jumpers on the vc's then tried powering that 1 speaker directly off the amp. It sounded great. I know the Sherwood isn't a super amp. but I am trying to figure out why that 1 speaker sounds so different from the others.

Also, we did not pull the wires for 4-of the zones but came back and added 2-more zones. The 2-zones we pulled sound so much louder and better than the others. Has anyone ever done a head-to-head cable test? The distances are similar, and I believe the original cabling is audio cable, also 16-ga. but a different manufacturer than what we pull. I am mostly just curious. Thanks for any suggestions. CDC

I realized that you have 6 pairs of speakers - the 'dual tweeter' speakers are prob dual voice coil speakers, and each of those speakers receives 2 pairs of speaker wires. Correct?

I don't know much about the impedance-matching VC jumpers, but are they set for 6 pairs of speakers?

The exterior DVC speakers are a good idea - where did you pick that up? I'll have to consider that one for my deck.

Edit - can you confirm that you have DVC speakers (maybe a Proficient model #), and that you have 4 conductors wired to each of these DVC speakers.

N-rad, that's right, 2-pairs, (left & right). They are "Proficient # AW600TT" We have used them in the past with very good results. (we like their ceiling and in walls alot, great sound for the $, IMO.)

When metering the "TT" speaker we read 4-ohms. When metering the speaker pairs we read 8-ohms. The jumper settings are the same for 6-pairs of 8-ohm speakers or 5, 8-ohm pairs and 1,4-ohm pair. The "TT" speaker sounds great when run straight off the rcvr. So, I don't think it's a wire issue.

Speaker cables > 50ft should be run using 12g wire. It's probebly too late to change that now... Try this: Remove two sets of speakers from the ceiling, one of which is the speaker in question, install it where the other speaker was. Turn the system on and see if the problem resolves itsself or not. If not, your speaker is malfunctioning, replace it. If it does sound correct, then you have either a wiring or phase problem at the other location.

Hope this helps,
Kent

if you trip the protection on the amp, you have short somewhere. disconnect the speakers and amps, using a meter to measure each pair of the speaker cable.
