recording booth (about 9 by 12 foot) with decent acoustics.

first..a booth that small for brass is not acousticlly nice. Use the TLM 170 with a pad if you want to do them together. If you need seperation add the 193 to the one your not using the 170 on.
Don't forget to use the pad on the mics.

I just got through recording a 14 piece horn band myself. It was very eye opening.

I put dynamic mics on each person inside a 12 by 20 room.(Some RE 20s / SM57s and some Beyer ribbons)
It ended up sounding good but mostly brassy and spitty. You miss a lot not getting the warmth and bloom of the mid to low end from the room itself.
If there is any way to work a room mic into the equation, it would help... Believe me!

Old ribbon Rca D77 or DX77 are da bomb for brass... You can get them on e-bay for about a grand apiece or you can get new clones for the same price...

you can't hane em right up on the mic. A little off axis and a little distance. If all mic's right...then they all become room mics for each other.

If the booth is all carpet and foam, buy some sheets of thin plywood or panelling to lay on the floor and against at least one wall (have players face that wall). Brass needs a live environment. An X/Y pair from several feet away works well for small sections.

I'd try tracking them individually in a room that small. Two players will probably acoustically overload the room...

With the mics you own, I'd use the TLM 170 with the pad on, off axis of the bell, and probably in the wide cardiod setting.

If you want to get something new, you can't go wrong with ribbons or old tube mics on brass. My favorites are Coles, RCA 44's and 77s (I haven't used them, but I'd imagine that the new AEA ribbons would be pretty amazing too), and for tubes the old Neumann UM 57...

Beyer M160 ribbons or Royer ribbons would work well for this application as well. Good advice above.

Royer 121's would sound great. Also would 421's. Throw up the B&K also. It will add a nice touch, maybe for some "room" sound if you can get it.

Is there any way you could open the door to the iso booth and have another room or hallway to put a mic in? If so then stick that B&K there....
