Man I should be calling him SIR!

Oh the trouble I'm going to get into! But if I'm lucky he's so old he won't remember who it was that did it!

Don't worry, he thinks your name is Mike so it's all water under the bridge.

In all fairness, which isn't really my best trait, here is a our beloved friend.

Pricing for VWR is up. $128 each. Data is supposed to also appear today. I have 4 VWR+apair of XBL domes sitting at the post office waiting for pickup. Based on proto specs Scott says they will drop into FH3, the direction specs probably went for production, i'm guessing will make them even more suitable, so that is where a pair will go for break-in.

I see the spec sheet shows 85db/watt. You have 4 in that design. Wouldn't that be about 91db/watt before insertion losses?

Do you have measurements of this design we could see? Would be interesting to see.

Default Some measurements

Well some measurements. I'm not going to release all of them. I did some in living room RTA quickly that show the general response. And I did some careful measurements with the WTpro that give me a low end of the overall response as 94.5 one meter.

See the RTA below. No peaking or EQ of any kind is used. There is a thirty hertz high pass. The tweeter is at and around 100 db/watt plus or minus 2 db. The overall response is plus or minus 2.5 db. The vertical scale is 5 db per major division.

Not to sound pushy, but why not share all the measurements? Whats there to hide? An in room response doesn't mean much for my room.

I'd like to know more about this mid. I still don't see how you arrive at 98db. The spec sheet shows 85. The response plot shows about 75db around 200-300hz. I'd like to know as much about this mid as possible without being able to hear it. Dave has a couple coming, maybe he'd be gracious enough to let me hear. I need to know by spring though. I'm supposed to start a center channel build for someone with a $500 budget. I think I'll go for the tweeter. But I'm hesitant about the mid.

I suppose this post is directed as much at Bob as you Any info would help make my decision easier.
