Rated 5 out of 5 by from Bra basHej på er högtalare byggare. Satt in Aurum Cantus 12 tum. Blev mycket nöjd med den. Kör den i 80 liters låda med trapp port. Blev inte bra första försöket fick dämpa den ganska mycket med ull. Och det blev bra tryck i den med djup bas.

Aurum Cantus AC300/75C2C 12" Woofer

Will it make a good mate for a denovo 12" seos horn crossed over around 1-1.2 KHz, in a sealed 2.75 cu ft cabinet? Possibly with an Eminence LAB 12 in a vented enclosure handling <80 Hz... 2x6 external dsp tri-amp system... 

Asked by: audiothings
This should work fine for that application.

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 ?

Asked by: gotama
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.

Asked by: gotama
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?
Asked by: benz
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?
Asked by: benz
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.
