That raises an interesting point. Banks of speakers (including tweets) are common in commercial productions as well.
Was there anything in particular that you feel that more tweeters brought to the table? In other words: and specific strong point to that driver you would equate to the tweeters being in multiples?
Now I'm back to using your 'I like' phrase. What I thought I knew about multiple tweeters told me it's wrong but Venus Hum's voice on Walter's center sounded better than on my Infinity PC350. More forward, more present, less laid back ...
I think I have gotten better at identifying how well a speaker reproduces let's say low', mids and highs from paying attention to what I hear. I think I've gotten better at noticing what different rooms sound like. I have for sure gotten better at identifying how well a speaker reproduces the human voice. That speaker just did a better job than mine ... plus Walter had that cranked loud enough to shake loose the popcorn on his ceiling but that's a different matter. Who knows, maybe my center just sucks. Let's face it, that center retails for more than I paid for all my speakers ... including at least one of my subs. So ... it should sound better than my center.
To answer the question, her voice sounded like it was more piecing, present, real especially with the hard 'e' sound. However this comparison is quite unfair. It should be done in the same room with the same equipment driving it. Which brings me to how this thread gets jacked.
I recently got a couple of rec'rs off eBay for Eddie's shop. Both of them together cost $38.
I think they were 70 watt and 85 watt Yamahas. Testing them with 6 Ohm Aiwa (screw those jerks for having a name that is unpronounceable and spelled wrong even when it's spelled right) bookshelf speakers revealed that the 85 watt one got the test tune much louder with much less distortion than the 70 watt one. This was a night and day difference that went well beyond the difference of 15 watts but yes when they were played at low levels there was no preference.
The good one ...
To bring my point back to the topic I'll say that Walter has an amp rated at 350 watts pushing his center.
What a maniac.
