Aurum Cantus AC-250MKII 10" Carbon Fiber Sandwich Woofer
Aurum Cantus AC-250MKII 10" Carbon Fiber Sandwich Woofer is rated 3.2 out of 5 by 5.
Rated 1 out of 5 by from Not impressedI bought these on a trip to see the races in Bristol Tenn. .Fantastic drive back through Virginia and Kentucky .On testing these drivers at a base line 50 watts power . They were distorting vocal sounds . And I had the active cross over at 500 hz. I thought, maybe my carver 55x was having issues , so I got my signature sun fire amp and still the same. So I grabbed the 12 dollar 8 inch grs and wow it sounded great. So I opened another 10 inch Aurum cantus and once again the same thing. As these cost 157 dollars as I bought 4 , I was not expecting this. I would have to say the carbon fiber cone is nice but I would not buy any of there speakers at this point. Bought 4 tang band 6.5 inch mid bass dumb bell weight speakers and am blown away by there sound. Now I have to drive 20 hours to return and get another set of drivers as I am in north bay Ontario CANADA.

Rated 5 out of 5 by from Great WooferI had purchased this woofer for a friend.I purchased it for it's power handling and quick transient response. Also for it's X-max need to move a lot of air.I did run into a problem. Received only one woofer and didn't expect to receive the second for another four months. PE service worked with me on this issue and rectified my problem to which I was very satisfied.Thank you PE you earned a satisfied customer and I would definitely recommend this product.

Rated 5 out of 5 by from Very GoodI'm not sure what the previous reviewers tried to do with these drivers but my experience using them in transmission line sub boxes is first rate. Smooth extended accurate lows with good upper bass/low mid response all the way up to around 200Hz (using a first order x-over)

Rated 2 out of 5 by from My nightmare with PEI do not recommend purchasing ANYTHING from parts express unless you have lots of time and money to waste! I ordered a Aurum Cantus woofer that was said to be "in stock", it was not only NOT in stock but was no longer available! It still says "in stock" a month later! What a joke! What is the point of saying something is "in stock" when it is NOT??? Then they sent me my entire order without the woofer, well this made half the stuff I ordered unusable! They also did not send me the tweeters even though they were in stock. So I tried to order the other Aurum Cantus DVC woofer, well they sent me the single VC woofer. Then I had to call again to have the correct one sent. Then when I got the other sent to me IT WAS A SINGLE VOICE COIL WOOFER TOO. IT TURNS OUT THIS WAS A MISTAKE IN THE CATALOGE! W.T.H.! Now I am trying to get my money back. Their "no hassle" return says payment will be sent "promptly", well that turns out to be 7 to 10 days for "processing". What a joke! So before you order anything make sure you talk to someone to make sure its in stock and make sure it is what it says it is. Do not trust the catalog on ANY specs! This has taken 3 weeks and still counting, because I still have NOT got my refund! Get it together PE or it will all fall apart!
