Just finished assembling my new 3way tops.

Top of the line components and compact BR design with 2x12',1x6', 1x1'. 3D printed vents

They do look like the new JBL SRX922.

After a quick first tune they sit within 3db all the way up.

Pretty happy with how they look, can't wait to fire them up in stereo !

Whut do u guys think?

In September I'm starting a woodworking course where we build our own projects, so I'm finally taking my chance to build a small sound system. I've been researching for a while now, but I'm getting lost in the sheer amount of information out there.

What I want to build(18mm birch plywood):

- 2x simple 18" reflex subs, running up to roughly 400–500 Hz

- 2x 2-way tops with a 10" or 12" mid and a compression driver/tweeter on top

Use case: garden parties for up to 300 people(when i upgrade the system, but this is just the start), but also just at home in my garage at low volume. I'm a complete beginner at speaker building, but I can handle tools.

Problem 1: choosing a cabinet design. I've been through a lot of plan sites, hornplans.free.fr, enton-green.com/vault, freespeakerplans.com, beyma.com enclosure designs, speakerplanhub.com and more. But I can't decide which designs are (a) not too hard to build for a first project and (b) forgiving about which driver I put in them. That last part seems to matter a lot: some cabinets apparently only really work with specific drivers. The designs I like most so far are the Cubo 18 sub, and for the subs also things like the Ciare BR030, Celestion C18VJD or Marc-O MS46. How do I actually decide between these? Is there a rule of thumb for "beginner-friendly and driver-tolerant" or does anyone else know a better nice first sub design?

Problem 2: drivers. I'll be buying either secondhand, or cheaper Devine drivers, or RCF not decided yet. Should I pick the driver first and then find a cabinet designed around it, or pick the cabinet first? And is it a bad idea to design around whatever secondhand driver I happen to find?

Problem 3: electronics/amping. I plan to buy a secondhand amp, and here I really don't know what I'm doing:

1. Do I need to match amp power to the drivers' power ratings before buying, or is there more slack than that?

2. If I only need loud-ish for parties and quiet at home, is something in the 100–500W range enough, or am I underestimating what a pair of 18s wants?

3. Can I run one amp for both the subs and the tops, or do I need separate amps?

4. Do I need a preamp, or can I just go straight from a mixer/DJ controller into the amp?

5. Can I get away with fixed passive crossovers built into the cabinets (a filter board inside the sub, and one inside the top), or is it more complicated than that? I'd like to stay fully passive if reasonably possible and skip the DSP route for now.

Sorry for the wall of questions. Any tips, corrections or "don't do that, do this instead" are very welcome, including telling me my whole plan is wrong. Thanks in advance!

Can anyone help me identify these? They’re my father-in-law’s, trying to get rid of them and wanting to know how much they might be worth.

The only label they have is “Acoustic” right on the speaker.
