Aurum Cantus AC-165 6-1/2" Carbon Fiber/Kevlar Woofer
Aurum Cantus AC-165 6-1/2" Carbon Fiber/Kevlar Woofer is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from great replacement speakersI just ordered these speakers to replace the woofers I had blown twice in the emotive XRM 6.1 speakers . the speakers that came out were very similar to these , ie high quality , but for some reason they would not last . these are irregular shaped speakers , and I didn't think I would be able to find a replacement speakers that would just drop in and fit . but these did , even the screw mounting holes were an exact match . are there any differences between the two ? there is no doubt the bass and mid range is better , in fact I can hardly believe it , because the original speakers were quite spectacular for their size . I am glad I found these and would recommend them . I would like to have a speaker with a row of these .

Rated 5 out of 5 by from very solid productFirst, thanks again to PARTS EXPRESS for their dedicated and excellent customer service. And fast and accurate shipping of course.I got this woofer crossed over at aprox., 3300 hz (2nd order)in a passive crossover, along with a MOREL MDS-29 tweeter. I added it's respective zobel network to the woofer, and the "remains" of high frequencies were gone. Very precise and well constructed woofer, and, very dinamic !!, i'm really starting to enjoy music right now.

Rated 5 out of 5 by from excellent driver!I have some diy speakers and I replaced my drivers "Vifa P17WJ-00 6-1/2" to these "Aurum Cantus AC-165 6-1/2".The only thing I can say is: WOW....what a big improvement!.the bass is tight and strong,the mid-range is clear and detail. I strongly recommend these drivers.

Rated 5 out of 5 by from Really nice woofers - tight, deep, heavy bass.Bought these as they are a good fit to replace some flimsy woofers on a pair of floorstanding mission speakers - made an absolute world of difference. Really tight, much heavier bass, quality mids. Plan to replace the remaining 4 with these excellent cones. Small for 6.5s though.

Rated 5 out of 5 by from great speakersThis was the first pair of Aurum Cantus speakers that I have ever bought. I knew they made outstanding tweeters, but did not know they made drivers as well. I use my AC-165 6-1/2" Carbon Fiber/Kevlar Woofer in a small vented enclosure with a 1" tweeter. The speakers have good imagery and the bass response was quite substantial. Impressed to say the least.

Doe's this fit for Infinity floor standing replacement parts for ref 2000.5 ?

Asked by: nynick
Unfortunately we have no reference guide as to what will fit certain speakers. You will have to compare the dimensions of this driver as listed in the product details online with the dimensions of the driver and cutout you are trying to replace.

Crossover

I planning to use Aurum Cantus G2Si Ribbon Tweeterhttp://www.parts-express.com/pe/showdetl.cfm?partnumber=276-400
Asked by: PeterF
The highest recommended crossover frequency for the G2Si tweeter is 2,500 Hz so you cannot go any lower than this. The woofer will start to beam around 2,700 Hz, so an ideal crossover point would be between these two frequencies.

Crossover

What crossover can you recommend, for 2 way system with this woofer?
Asked by: PeterF
There are many options that will work, we would need to know which tweeter is being used before we can help with a crossover.

What is the width across the flats?

Asked by: fpitas
The diameter across the flats is considered the "Overall diameter" in our description, and is 6-3/8". Across the outside of the mounting holes, the greatest diameter, will measure approximately 6-15/16".

Are these TS paramaters correct?

I suspect there may be a problem with the datasheet from Aurum Cantus on these... An older edition of the PE catalog http://www.partsexpress.com/catalog/pdf/203pec08.pdf lists one set of TS parameters for this speaker. The current PE description and the Aurum Cantus datasheet agree but list a different set of values from the ones in the older catalog. I have tried these speakers in both .75 and .38 ft^3 sealed boxes and I the response I am hearing seems to agree with the older PE catalog data.
Asked by: jason256
The copy in our 2010 catalog was in error. The current catalog and web information is the correct information for this product.
