I could just hear my wife say “do they have to be that big” :problem:
To be clear, there are two sets of speakers in that photo. The lighter colored ones in front are the new ones. My understanding, limited as it is, is that you design speaker cabinets with a specific interior volume in mind to achieve the sound you're looking for. So yes, they have to be that big to sound like what the designers intended.

^^^got it. On my phone it looked like one large speaker but zooming in I can see the smaller one in front.

It's not a great photo. I'll post more later.

Interesting build! I'm guessing that the internal baffle in the cabinet produces a tunnel creating a long duct behind the driver that ends at the gap at the bottom of the cabinet. This would make them a transmission line design, a method of loading the driver for optimal bass output and drive unit control. If so, ensure the join to the cabinet walls is airtight.

Regarding power, the lower frequencies are where power is needed and these drivers look like they avoid that. Even in relatively big power systems, most of the music lives in the first Watt. The power is only really needed to drive big transients and low frequencies.

Out of interest, what are the speakers lurking in the background? They look very interesting.
C63 Sealander - Hunter Green. Twelve Ti -Purple. C65 Aquitaine - Seagrass Green. On order: C63 SH21 Blue Marine (delayed 4 months plus 3 months plus 3 weeks. So far). C1 Bel Canto - Voila (delayed). Waiting. Endless waiting.

They’re also a kit from Bottlehead. They’re called Jägers and they’re unfortunately retired due to cost of materials, I believe.
