Aurum Cantus AC-180F1D 7" DVC Woofer
Using as sub/mid in car doors with the Pioneer Stage 4 TS-S062PRS mids (on axis on the dash) in a simple 2-way active with no tweeter, would the the Cantus crossed b/w 400-800Hz work here. Would imaging suffer? Bandpass is also available. Thanks.

Can this sub be used sealed and if so what size?
If you click on the SPEAKER BUILDER tab and then WOOFER SELECTION GUIDE in the right column - you can see these specs for many drivers which helps you in making your decisions. For the AC-180F1D a .66 cu ft enclosure yields an F3 of 72hz - making it a perfect mid-woofer for LCR home theater or mini-monitors crossed over to a subwoofer. In a ported cabinet - you need 2 cubic feet for an F3 of 38hz - which is right at the drivers Fs so there would be some performance and amp/impedance issues... This driver will perform best in a sealed enclosure.

Can this dual voice coil "4-ohm" driver be configured as an 8 ohm driver?
I would like use the stated "dual voice coil design allows unique crossover options" capabilities to transform the driver in to a 8 ohms so i can us it, along with complimentary 8 ohm drivers, in a three-way speaker.Or do they have a 8 ohm vesion with similar low frequency response.ThanksPatrick
This driver has two 8-ohm voice coils, so what you could do is hook up just one of the voice coils, and that will give you an 8 ohm load. All DVC woofers can be connected in one of three configurations with no ill effects at all: parallel, series, and running just one voice-coil. In the case of this woofer, those configurations would give impedances of 4, 16, and 8 ohms, respectively. Note, however, that if you run just one of the voice coils, then the power handling of the woofer will be approximately 60% of the rated value. In this case, it would be about 60W RMS / 85W max. This is because there is half as much voice coil wiring to dissipate the power.There is some debate about whether or not a DVC woofer can be run with just one voice coil attached, but I can assure you, as an electronics engineer and experienced hi-fi enthusiast, that doing so is just fine. The only issue is the reduced power handling.Alternately, there are 3 other Aurum Cantus 7" 8 ohm woofers over in the "7 inch woofer" category here on Parts Express. They have fairly similar specs, esp the AC-180F1, which is the single voice-coil version of this AC-180F1D.
