The white coned drivers are the ones i like Should sound good with a pair of mini a's.. What is the cost for a pair of those drivers?

FE126 are ~$36 each from Madisound.

At some point i'll have stock, but probably will be selling them modded (your choice of colour)

Chris: Thanks for the advice but I managed to create a Jig by cutting 5 30 degree blocks and clamping them plus a backer board (to place the piece to be cut up against) to the miter guide. I set the saw to 30 degrees as well and voila! I have 60 degrees. Worked like a charm. Had a kick back on the first go round, (lucky I wasn't standing infront of it) the 200 mile per hour board just missed me. Anyway, I have them all glued up and am now working out the CC and lips to mount the baffles to. I should have them running tomorrow. I will post then. Mother's day took it out of me. MY GF and I went to visit my mom, and my GF is a saint. She has the patience of Job. Goodnight all!

I'd suggest wait until you hear them with the modded 126's. With your mini-A's and silver interconnects, detail and extension though the top end shouldn't be a problem. Save the expensive ribbons for a mid/bass driver that really needs the help (e.g. WR125's)

Jason, et al: don't forget that any of these rear mouthed horns really need either a pair of corners or well executed reflectors for optimum low end weight and dynamics.

While there are some issues with soundstage "holography" due to side wall reflections in the as yet untreated new listening room, there's a huge improvement in the subjective quality and quantity of bass over the open plan upstairs space. ( at least 4 times the cubic volume)

ask Brent about that

chris, i'm talking about the ones you built and loaned him ? the ones with the fostex in them. NOT the ones you built for him.

Does brent still have them ?

Since you may need to decrease the volume of the CC, you might want to cut some 2x4 or even 45 degree chamfered 4x4 material for solid blocking at the rear of the CC.

After some a short listening session Friday ( 2 hours), I decided to permanently reduce the CC, and open up the void even further. As you know, these aren't huge boxes; due to hatchet work (actually my trusty 30yr old hand saw) and bondo fill required to modify the box, no pictures 'til after another listen; if worthy, them some veneer, or at least a quick coat of flat black primer ( rat rod hi-fi at its best)

[Harderror]

I created a 45 degree cut (both ends) board to block the void. I will fill with dampening material of some kind. This reduces (by my calcs) the volume of the CC to 1.4. I am thinking that it will need to be reduced even further so I am playing with ideas on how to do this. I will be listening for the first time this morning so...

[chrisb]

Too much damping material will increase the effective volume of the CC.

To reduce the volume you want to fill with solid mass - wood, metal, 1 litre filled paint can (no kidding - that's the first thing Dave grabbed from the workshop )

Make sure to treat the cone material as well as the other driver tweaks noted:

not a subtle improvement on either the 126 or 127

Jason, it sounded like you were asking about the ribbons.

If you mean the Fostex 126 mini-hybrids - ask Dave - he might still have them kicking around. But frankly they're sadly far behind the performance of either the modified Buschorn MKI or seriously lapped by the Frugelhorns.
