Rugged tweet that wavecore, but 30 degrees off axis = big droop.

After playing with horn loaded dome morel versus my now morel dome, I'm not sure I can live with a horn loaded dome's dispersion now. Don't quote me, but couch wide highs may not be an option at 7'.

Plasnu, found the minidsp mic and the USB pre-amp for testing!

Phivates - D28 as in Dynaudio? I do have a pair of those on the shelf,,,so old now, but only used once in a 1986 Blaser. As far back as that is, I remember how nice they sounded.
btw, the Wavecor doesn't weigh much, very light weight, not as much as the Dynaudio.

Norm, say I did have my tax return $$ I'm stuck now with 5 fresh boxes with 4-1/2" cutouts, any ideas?

Yes Dynaudio I really liked the D21 but that was way back in 1986 for me too. Its waveguide resembles the Wavecore while the D28 and Morel clones are a bit closed in at the throat.

Doug definitely get some measurements! I think you will be very pleased with the improvement you get if you design a crossover based on some actual measurements of the drivers. I was thinking I'd like to do a sim of this combo, but I could not find any measurements of the anarchy drivers.

Lol, if you already cut them out then go for it.

The wavecore outmeasured the morel, and the morel is rugged, like it has that single cap crossed at 4750hz yet 6db down at 2khz, it took all 80 watts from receiver crossed at 120hz, i tried to blow it. But a 10" whizzer also 6db down at 2khz, my wife is opposite end of couch and I'm at chair at feet end, i need dispersion sitting 8' from tv.

Knowing what i know now, much of texture comes from midrange in a 2-way.

Less dispersion can get you more volume in a room before it "over loads".
I had vega 3 ways, sounded distorted in living room on receiver turned to 9:00, in a 30' x 60' room, receiver could be turned past 12:00. My 12" full range was similar, no matter how loud it got, it wasn't annoying blur.

I'm stuck now, but I'm going to try my 12" 2-ways to a receiver to sub at 100hz. Maybe try my solstices first.

Now i know why in a review of diysoundgroup tempest (12" 2-ways) that one said they are a 9.5 on movies but a 6 on music. Watching movies, I'm not listening for the mouse farting at 1:32 on track 8, or the texture of a cymbal.

Steve guttenberg has it right, ideally you have 2 pairs of completely different speakers that each excell in their own areas.

I'm happy you are using the exact same speaker all around you for theater.
So many people don't get that.

Default Interesting

First attempt at testing:

#3 is a RS bookshelf speaker to add validity to the test setup.

Looks great to me. If this is measured @1m, the tweeter level might be a bit high side for audiophile speaker (if you feel occasional harshness).

I like the tweet a bit hotter (past 5khz) because i usually listen at lower than 90db (fletcher munson curve).

Tried to build a 2nd xo out of old parts...pfft that was a disaster.
However, when back to the 1st build and that still looks pretty good.
[changed one small resistor in the tweeter circuit btw]

Trying to make a crossover point at 1500Hz with gate at that same frequency ?

I'm affraid that is quite inadequate for any serious crossover work.
