Big women need large diaphrams.
Petite girls need small diaphrams.
Rock On!
 
Borrow a set of both(if possible) and try one set and then the other. Then try one of each. If you still can't decide, have a shot of your favorite scotch, have a friend hide a small dia in one hand and a large in the other. Close your eyes and take a pic. In theory the scotch should make your bongos more acceptable. I actually recorded some bongos ( we used the small childrens version ) with an AKG 4000B sounded pretty kickin' to me. But I think if I were doing vocal tracks at the same time I'd stick an sm57 on the puppy and let it ride.

Here's a great link that pertains exactly to your situation. In fact it discusses almost exactly what we have been talking about. It points out the advantages of small diaphragms for off axis response and for transient (impermanent and very quick) noise response. Make sure you look at all 3 pages. On the second page it also points out the advantages of a large & thin-diaphragmed condenser mics.

If you're doing vocals at the same time a small diaphragm is definitely the way to go (generally speaking).
Have fun!
 
good article

I actualy like the sound sample of the cheap shure sm57 better on the vocal comparison - the consonants are softer.
 
Amazing !
I didn't see that article but it looks like our entire disscussion is there.

But here is my outlook at the freq issue.

As he wrote
The high freq transients are extremly fast and gone extremly fast. The fsater the dia the better. The smaller - the faster - the better.
A mic's transient is very related to it's high freq response. The more responsive the dia, the better detaild the sound.

Some thing that was not written there are some negative side to the high freq respone of a large dia:
A negative side of a large dia is that it tends to not move together as one unit but has a tendecy to break up. This I have not seen with my own eyes but have heard this from a mic builder.

Another factor is the heavyness of the large dia will effect the high freq response as well.

And last the diffraction around the edges of the mic's capsule will effect it's response as well.

I won't even get into single capsule or double.

But as for vocals I would stick with a large capsule even with the off axis problem, To prefer the fuller-rounder-softer sound.

I also have to end this disscusion with the fact that I NEVER choose a mic
with the price-size -specs in mind.
The 414 can be great for overheads and they are large. but.....

As for when I do T.V. or live shows I will always choose a small condensor for estetic reasons.

Nice to talk to somebody about recording every now and then and not about FT.
 
Just bought some Mics

Well, partly as a result of this discussion I just bought 2 small diaphram mics. When I explained to the salesman that I'm recording guitar and voice simultaneously, he recomended that I go with a stage mic - the AKG C535 - for vocal, and a small condensor - the Shure SM81 - for guitar (and for small percussion). The theory is that in this situation, having very low off-axis pickup is most important. Also, my mixes are dense, so having the full range sound of a large diaphram might just cause more interference.

Now, I'm also wondering (and this is purely a matter of taste) whether having a slightly less sensitive dynamic mic might actualy make vocals sound better because it would soften harsh syllabals.
