Hi All,
Looking to build a nice set of 3 way floor standers.
I have a large room, approx 50-60m2, so looking for a decent size speaker to cover it.
Will be running a Denon X3800h (or extra amp if required when going passive)
I have been doing heaps of research to find a design, but i'd get stumped with massive freight costs, or unable to buy the driver etc.
So I have decided I'd like to build a 3 way, SB accoustics build, mainly because I can easily source the drivers in Australia.
I have tossed up the idea of active vs passive, was thinking maybe a couple of Hypex amps. So i could do a bit of dsp etc, if required.
I had nearly decided on a set of Zaph 12.3, but I'm undecided, thought i would ask some advice before deciding.
The physical size here is no worries.
So my decision basically comes down to active vs passive (1.5-2k worth of hypex amps before i even start the build) vs designing/testing crossovers and buying an amp if needed.
I don't mind either way honestly.
Then it just comes down to drivers. I do like the idea of having the 12" low end, 6-7" mid and tweeter.
I've seen a few designs that have the likes of, SB29RDNC, SB17NRX, SB34 variants.
If i went passive and crossovers costs didnt get out of control, i could probably stretch the driver budget a bit higher. EG. Satori midwoofer, TW29R tweeter
Going passive will require me to ask a lot more questions on here as its been years since i have dabbled with speaker building.
I've got a Umik-1 & DATS V2. Happy to learn whatever programs needed to do sims.
I've got plenty of access to panel saws, CNC routers etc, so i'm all good for the woodworking side of things.
Where should i go from here?
If you were in the same boat, what would you build?
Thanks so much in advanced!

Given you're in aus, wes.com.au would be the best source for crossover parts.
In terms of multi-channel class D - https://www.buckeyeamp.com/shop or https://www.audiophonics.fr/en/power-amplifier-c-6306.html seem to offer good value. Latter is pretty good shipping to Aus.
The latest MiniDSP FLEX HT is coming out (8 channel DSP) which may be all you need, depending on your sources. This would allow a good active setup.
If you aren't afraid of computers - you can run Linux, CamillaDSP and DAC of your choice (Topping DM7 8 channel DAC) which is my combo.
I have a few Class A/B amps that I've acquired. Rather than buy new - buy any old combo of amps and gain match in the DSP (pretty easy to do). You can always upgrade later.
My pic of all software is VituixCAD for sims (active or passive and hybrid are all supported) and REW for FR measurements (I also have a DATS). These are both free, but I recommend you donate as they are very fully featured (note: I have no interest/ relationship with the developers, but plugging them as the software is brilliant).
There are a few smaller footprint SBA designs around (dual 8" 3 ways). Zaph's is an obvious larger 12" 3 way, but since you have the measurement capability, I'd go whatever you want.

Or SpeakerBug for passive components.
Ditto for buying good quality used amplifiers.
I went cheap and cheerful using BehringerCX for a long while with a passive cross to the tweeter and I now use a DCX because A- It Works and B-I'm cheap

semi active is also a possibility, using one amp for passively crossed over mid+tweeter.
i guess you have seen this very informative thread:

I'd build this one, easy enough to come up with a similar xover and/or scale up the woofer if required:

definitely passive, I don't need more electronic junk in my life
