DIY iso cab I threw together about 6 years ago, built around a celestion G12 Vintage 30 (8ohm) speaker. Includes the speaker (speaker cable is soldered directly to the terminals on the speaker), mic mounting hardware and the cabinet itself. The insulation inside is rockwool safe n’sound/roxul or something of the like, and the outside is covered in automotive sound insulation and it is on wheels. Functions well, definitely reduces the sound enough to where I’ve run cranked tube amps through it and not had any resulting conflicts with roommates over the years lol.
