Could a v3 tweeter and a v4 tweeter be used in the same tower without causing any problems?

Other than looking a bit oddball, it would work fine. The greater power handling of the v4 tweeter would be negated in the system as a whole though too.

Interesting.
Thanks for confirming.

Knowing there are always compromises to contend with I can't help wonder if there are unique benifits between each type of install.
More specifically does an inwall L/C/R have an acoustic benifit over either the onwall or stand alone speakers?
Its not about use of space (to me, at the moment) but I realize it maybe the number one reason others go that route...is there an acoustic sound quality benefit?

I will assume there is a subwoofer in the mix. Between an on-wall and an in-wall it matters greatly if the in-wall does not have the drivers mounted slightly proud of the wall. Between an on-wall and a stand-alone there is a benefit to the stand-alone if you have the flexibility to play with its position in the room.

Balanced XLR vs RCA connections for both sub-woofer and separate amplification connections - a few questions to show my ignorance on the topic:
1 - What does the term 'balanced' mean in this context? (I don't get it since it'll be carrying one channel of information)
2 - Is there an audible difference between the connections?
3 - For HT purposes, is there a reason to use one over the other?

It's visually obvious XLR is a more robust connection which makes sense for on stage, portable equipment and the like, but for stationary equipment in an HT, what's the advantage if any of XLR vs RCA?

Thanks!

The benefit of balanced cables in HT is only if your house has ground issues. Like a ground loop or something like that. If your not getting any audible noise from RCA's.. Then there wont be a benefit...

I use XLR's... But, only because 2 houses ago my system was picking up or transmitting an audible noise.. XLR's fixed that. However, i have multiple outboard amps that are getting a signal from the processor... If your using a receiver there likely wont be any benefit today in the time of HDMI cables..

Today i only use the xlr's because they're already bought and paid for..

Also, from an electrical theory perspective... There is no benefit to spending top dollar on an xlr cable... As long as the connections are good; your good to go...


I'm not Ian, but hope this helps.

Thanks Dakkon, that link helped explain things. I had just assumed XLR was better without ever actually understanding why. I'm now all edumacated.

Cheers,

Dakkon is bang on for home use. In a stage environment however, with cables running all over the place then balanced is the only way to go. The three connectors inside the balanced cable are carrying the ground, the signal in-phase, and the signal out-of-phase. Any noise picked up along the way has the same phase on both cables so it is cancelled when the out-of-phase signal wire is put back in phase at the receiving end.

I'll say the main reason I prefer to use balanced cables isn't for the balanced aspect (haven't had a unit with a balanced output for a few generations); it's for the connections. I've ruined several RCA jacks on different equipment because the connectors on the cables were too tight. No grief with XLR, with their click-in mechanism.
