Aurum Cantus AC300/75C2C 12" Woofer
The diameter on the speaker cab. is 11in. Would that be a 12 in woofer?
The cutout in the cabinet can be an indicator of the nominal size of the speaker which will fit, but not always. As listed on our website, "A" is the overall diameter of the speaker including the frame or faceplate, "B" is the inside diameter of the required cutout, and "C" is the mounting depth. This particular speaker requires an 11-1/4" cutout, so it would not fit in your 11" cutout without modification to the cabinet. This speaker is also 13" overall, but is listed under 12" woofers simply for classification purposes.

Can this be considered a high end product?
Yes, Aurum Cantus drivers are generally very high quality, although some Scan-Speak, Seas, or Usher drivers may produce even better results. But, at this level of quality and price there isn't a huge difference between any particular driver, and differences are fairly subjective.

What size box
What is the optimum size box and vented or sealed for best hi fi sound?
This is a very exceptional driver. Venting and porting both have their benefits. The best thing to do is use some box software or a box calculator that you can search online and fill in the specs of the woofer. You can see the box size, dimensions and port length and diameter if a ported box. Audiophiles consider sealed better than ported. High efficiency and sound reinforcement typically go ported. If you are using a dipolar mid/high, a ported bass can have a better blend with the openness of that range. For sealed - design with a total Qts of .707 for flattest response. When you use the box calculator - typically one set of specs makes sense and the other doesn't - so if the ported or sealed suggestion looks whacky - it's telling you that the driver designed is optimized to be used as ported or sealed. Not all drivers can be used both ways.

Would the ARUM CANTUS AC 300/75C2C "12" be good replacement
I have the martin Logan Monolith II and the woofers are gone. Would the Arum Cantus AC 300/75C2C "12" BE AGGOD REPLACEMT WOOFERS? AND ARE THERE A BETTER UPGRADE FROM THE ORIGINAL ML woofer?
im not familiar with that martin logan model,but these are top notch acoustic suspension woofers for 2-2.75cu.ft. with f3 in mid 40's

The Woofer has 6 mounting holes and the enclosure of the speaker cabinet has 8.
Would this present a problem when it comes to mounting the enclosure in the speaker in the cabinet?
It is not uncommon to have to drill new screw holes when replacing a woofer. I would recommend drilling 6 brand new holes and sealing up the old ones.
