Peter please keep posting. I, for one, would love to see photos of the fabrication of your Lowther Opus one model B step by step.

I have to make these big cabinets alone, withoud help. It would be impossible to turn down this heavy(about 120kg) cabinet later by myself. I install 6 rollers(costors) for each baseplate. The baseplate(18mm Th'k MDF) seems to be a little weak. Some reinforcement plates and damping materials are added under the baseplate to reduce resonant. The damping material is not shown in the photo.

I spent a lot of time to figure out the assembly process. C clamps should be uneasy to use for this non-rectangular cabinet. I think screws and wood sticks are more useful. Two side and back panels are assemblied first. Pre-assembly by screws is absolutely a must before gluing for every panels. Top panels are routed with grooves to bound the two side panels.

I noticed you have a JX92S based transmission line. I have some treated JX92S drivers but don't have the proper enclosures for them. Wonder if I could try them out in your enclosure.

Peter,

Nice work you're doing on those cabinets. Smart thinking with the rollers too! You're not only making a nice pair of speakers, you're even a good photographer as well!

Hi, soongsc

If you want to test whether your driver gets to work or not, you can connect an amplifier(<50W) to test this fullrange driver without an enclosure. If you want to evaluate the performance of JX92S in the VTL enclosure, I am happy to welcome you. Please email me for my address.

Thanks Peter,

I have sent you a PM.
Yes, I have done some measurements, as shown in the EnABL thread. But have never had the opportunity to listen with enclosures because this is being done on the sidelines. I have been hoping someone with existing enclosures in this neck of the woods would show up.
