I am gonna make a floorstanding three-way. I already have:
1. SEAS w22 ex001
2. Seas Excel millenium tweeter
I am gonna make a sealed three-way floorstander. I am going to use the w22 for bass, and therefore require a good mid unit.
It is going to have external cross-overs, because I may make them into active's at a later stage.
I am after a very neutral mid range driver that images and times very well. My ears are accustomed to Yamaha NS1000M's.
With that in mind what should I buy:
SEAS W18's?
ATC's
Scanspeak
Audiotechnology
anything else?
Help me please

-unless you have an active solution for the mid-bass driver, baffle step loss will be a problem.
considering everything else is seas related, I'd probably go with an excel magnesium mid to accompany your drivers.

I would prefer smaller driver than W18 for the midrange (to be crossed around 700Hz). First option is W11, second is W15. First it must be simulated to find which one will most probably fit better with your tweeter. This can be your last speaker.
If you're not sure you can design a good speaker, better choose W15 because I think many others have used this W22-W15 combo. Troels' Poor Man's Stradivari is one example. But smaller driver such as W11 in my prediction will make a wonderful top quality speaker if you don't mind to "work hard".

Why not just cross at 1400 LR4 electric, notch at 4.8kHz, and skip the mid altogether? T25 and W22 sound pretty good together without any "help" . . .

I recommend to not use anything else than magnesium seas driver because the mariage with other midrange will be difficult.

Agree. That what I will do. But this is difficult if you don't have good ears. You can make one that measures good but with complex filter the chance to sound good (enjoyable, no fatigue) is small.

Note a 3 ways will sound better, specially in the high midrange, low treble.

The "chance" does not have to be "small" . . . the Linkwitz crossover used in ORION works well (with a few obvious adjustments, like no dipole correction, but baffle step instead), and it is easy to replicate.You can make one that measures good but with complex filter the chance to sound good (enjoyable, no fatigue) is small.
That a three-way will necessarily sound "better" is open to some argument, and depends a lot on the crossover design (see my comment to Jay, above), among other things. There are some benefits, and some disadvantages. Overall it may well be a wash, or even favor the two-way. In this case I think it does favor the two-way . . .In the case of a 2 ways, the kit trym exists : THE ART OF SOUND PERFECTION BY SEAS - Trym

For a 3 ways, Troels did a good job. His comments are very instructive 😉

Have fun.

Oh, you're talking about active crossover. I thought the Orion xo is not openly published.

When 3-way is possible, like in this case I suppose, no way a 2-way can equal a 3-way. There's no disadvantage with 3-way except for higher degree of design difficulty.
