Aurum Cantus AC300/75C2C 12" Woofer
The woofer/subwoofer in my Simmons DA200s is toast. It is 12inch 8Ohm 150Watts(RMS) Simmons cannot supply the response frequency. In the manual it lists the response for the entire unit to be 20Hz to 20kHz. What would replace it but with higher Wattage?

Is there a box ready made which I can buy for this woofer. It will be used as a normal woofer not as a subwoofer, for bass anything above 80Hz., and it will be used in a room. If not, would a car box (sealed) work well with this woofer ?
We do not have a box specific for this woofer although it will work well in any 2 cubic foot enclosure we offer. Baffles will have to be modified in order for the frame to fit properly.

Hi, I am building a main monitoring system. My 2way satellites cannot keep up with the sub so I need to boost this range (400hz-80hz) by adding a 12' driver on each channel. Is 1 enough or do I need 2 on each side coz i got 1x1000WRMS sub each side.
Unfortunately I cannot say if one will be enough with the information provided. Using this from 80-400 Hz will limit the amount of power needed to drive it as well as increase overall output. This woofer will handle full power if high passed at 80 Hz.

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.

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?
This is hard to answer without knowing enclosure volumes and port diameter and length. If you can provide this we can help with a woofer recomendation.

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.
