They do look awesome  :rubhands:

I suppose when you use a vernier it needs to be of good quality...

Awesome stuff!!!  :2thumbs: I want a CNC machine too  :sd:

Thanks Ian. It does make sense. I'll keep the opening the correct size. I am doing a tapered design though. I am reducing from 1.5x Sd down to Sd. The calculated line is 156cm but will shorten that to 145cm (~8% reduction) depending on the build practicallity. I am also doing 2 folds as I want...

So I am busy with a design and have a couple of question... With all the reading and calculating etc, I think I have a good grasp of what needs to be done to build a TL box. If I make the port 10% smaller than the required size of Sd, I will add pressure to the line which might cause back...

That design looks serious! [emoji16] What software do you use for the layout? Sent from my SM-G930F using Tapatalk

That looks pretty good! Nice job  :2thumbs:

Awesome stuff! Can't wait to see the design  :2thumbs:

To keep it from falling over, add feet to the rear on extensions like Hi-Phib suggested but only in the rear. Then raise the rear to accommodate the extra height from the feet but keep the rest of the shape as is.

SMPS supplying a Class A @ 311Vdc 15A ~4.5kW  :EGrin: Transformerless... Just silicon. Actually I did a project like that, just not for audio (project never went to production) I rectified the 220Vac to 310Vdc. Used some special FET's (each capable of 700W) in a push pull config. At working...

The Vf of each diode will be different but it will be mV differences AND because of the lower current over the individual diodes, the Vf of each diode will be lower in anycase. I don't think you need to worry too much about this though.

What if you use 2 switchmode supplies with positive and negative rails. That way the in rush will be controlled and any high current requirements can be taken care of. Switching noise should not be any issue if you run the switching frequency at higher than 300kHz. You wont need as many large...

Seems easy enough  :point:  ;D

What are the benefits of TL vs reflex design? And what type of drivers would work well in a TL box?

NICE Build  :thumbs: :thumbs: :thumbs:  ;D

They are working... After a while these drivers have settled or my eras have become accustomed to their sound... The midrange sounds dull or lacking or not as sharp or clear... The base needs adjustment but the highs are good. BUT When I connect the set to an old school JVC amp with about...

I need to do a deal with Audioholics in Edenvale but would like to know about their service. Anybody done deals with them? How is their after sales service?

TRX distributes Mouser parts.

I use a Magnum 2002-80W at work. Its fast and I can set temperature easily. Replacement tips are cheap as well.

Nice. These guys have VERY good pricing on PCB prototype: https://www.pcbway.com/ The courier is more than my PCB's (50mm x 25mm) though...  :nfi:
