Aurum Cantus AC165/50C2C 6-1/2" Midwoofer
Aurum Cantus AC165/50C2C 6-1/2" Midwoofer is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Surprisingly Good!I bought these to replace my 6-1/2" Peerless woofers in a 2-way setup. Of course one always hopes to hear an improvement when upping the price 100% and hear an improvement I did. More mid range pop, punchier bass, just a livelier more engaging sound.These woofers also blended well with the two tweeters I tried it with; the Vifa XT25GS60(with 3db L-pad) and the Morel 308. I preferred it with the Morel 308.For my tastes I really, really like these woofers with solo acoustic instruments such as cello or guitar but they can rock out.I'm satisfied as my goals were achieved with these woofers. I wanted to get a livelier more dynamic sound and they delivered.

Would these work for a replacement driver in some old Celestion SL6S's? Can't find any details on the original drivers to see if they would would be a good impedance and sensitivity match

Asked by: vapemaster
Unfortunately we do not have a cross reference for this type of thing. If you know the sensitivity of the speaker as a whole, you can bet the woofer will be within 3 dB of that number. The volume and tuning of the enclosure is also important. If you could call or email us with this information we can try to help further. 800-338-0531 x1 or tech@parts-express.com.

Can these be used in a car door in infinite baffle? Will be crossed from 200-2000hz.

Asked by: fyalinks
IB will not make much of a difference with anything above 200 Hz so I do not see a problem with this.

Wondering if these would be a good replacement speaker for a set of Definitive Tech BP-10s

Asked by: MatFrat
As long as the dimensions fit these should work, these are closer to a 7" frame as shown in the product dimensions..

Enclosure size difficulty

I have tried several enclosure calculators for this driver. Each one has produced an enclosure size too small to accomodate even the physicial size of the driver. What is an appropriate size enclosure and is it best sealed or ported?
Asked by: DJ027
This driver should perform well in a ported alignment, with an enclosure volume of approximately 0.42ft³. To avoid port noise, you'll want to use two (2) 2" diameter ports 6" in length; or, one (1) 3" diameter port about 7" in length. In either case, the enclosure itself will be tuned to approximately 70Hz, with an F3 frequency of around 65Hz. A larger enclosure will not provide significantly lower frequency response, but it will exaggerate the potential peak in the response around 70Hz. A smaller enclosure will minimize the 70Hz peak at the expense of low frequency extension.

Infinite baffle application?

Would this woofer work OK in an infinite baffle application, such as an in-wall speaker or even in automotive?
Asked by: Jeff B.
No, with its Qts value of 0.19, this speaker is more or less the polar opposite of a good candidate for infinite baffle application. It will perform much better in a ported enclosure of appropriate internal volume. For infinite baffle or mobile audio situations, you want to have a Qts of at least 0.50, and the higher it is, the more effective it will be in your infinite baffle application.
