Hello

I don't know where I read it anymore, but if I'm not mistaken, the center of the port vent must be 100 mm above the inner bottom.
I believe you should find this link interesting:

Mine is 4 " from inside bottom. I had help from people more knowledgeable than I when I did my build. Scottmoose, Dave and Renron and many others walked me thru the build. Small Thor

I put Reputes on the bottom and lifted the cabinet by 4 inches using a stand. This way it was influenced less by placement.

Thanks,

I’m building the small Thor, and have started cutting the 19mm MDF.


Center of the port 4”/10 cm from inner bottom seems to be the right position then.


I’m going to lift the cabinet up from the floor by 7 cm. Probably by using some kind of stand.




Thanks for the link

Default Rubber protection on the woofers

The build is moving slowly but forward There is one thing I seem to not find an answer for, can some of you with more experience than me in speaker build help me out?

The woofers have a rubber protection on the back of the magnet. Earlier in the thread it has been mention that the braces should be close-fitted with the woofer for support. Should I remove the rubber protection and make the braces support the magnet/woofer frame directly or should I let I stay on?

And when the wooers is mounted with the screws, it will be pressed a fraction more inwards than when I just hold it in place for checking if it fits. Should it be some pressure on the back of the woofer to the braces, or should I leave a small gap (couple of tenth of an mm) so the woofer just getting flush with the braces when screws are tightened?

Hello

According to the recommendations of the most knowledgeable, drivers must press the rear structure sufficiently to transmit vibrations to that structure, but not in a way that stresses the basket.
I hope it helps.
Best regards

Carlos.

I do not expect tthe plastic cover will be an issue at the frequecies most of interest.

The fit is trickey to get, ideal to fine tune it with a side off. It is easier to shim than to remove most of the time, sam shims of venner or even a piece of paper. Chris got so good at it i rarely had to adjust after he delivered cabs. One buid did need just a single piece of paper. You do not want to stress the basket/driver or not have. atight fit. (Carlos pointed out the same :^)

Do not overtighten the screws. Only just as much as is needed to stop a real or imaginary washer.

Thanks forreplying so fast.
I will tryto keep the rubber protection on, if I can get a proper fit. Since the rubberis somewhat flexible I assume I can have a bit tighter fit (let the rubber compressapproximately a couple of tenth of an mm), as the rubber will flex some and notput on an instant pressure as a direct fit on the frame would. Or would eventhat be to munch pressure?
Dave, yourcontribution is amazing. Thanks again for being so patient and sharing so much knowledgeto us with lesser knowledge.
