Sorry, I haven't tried the Sigma 18, nor have I even modeled it to see how it will act. You want a slightly overdamped alignment for most rooms. A flat alignment is good for very large rooms.

The Sigma 18 and Magnum 18HO have almost identical T/S parameters. The Sigma 18 should work well in the Audiophile series 7 Pi 18 enclosure. The Sigmas have a great low price and more Xmax, but Magnums have lower distortion. (Hence the "Audiophile series")
I have heard the Magnum 18HO on two occasions and they have very nice bass indeed. I listen to Sigmas every week at a friends studio and I think they are great woofers. The distortion is not obvious, and the price is nice. If the Magnums are bad for your budget, the Sigma is a good compromise. I may be using them in a DJ setup soon.

Good info, Thomas, thanks. I wasn't in a place where I could model the Sigma 18, so I couldn't be much help. I'm glad you could assist, your comments were very helpful.

I'm working with some B&C woofers and mids, getting ready to offer more options. Looks like they'll work well in the Audiophile and Professional Series, and I might offer B&C tweeters as upgrade options on some of the other lines as well.

Hi Wayne,
As it happened I have been modeling 18's lately for a dj setup. The Magnum & Sigma 18's were on my short list so I had the answer on the tip of my keyboard

I really like some of the B&C stuff on paper. I am seeing good feedback from users too. Can't Wait to see what you cook up with them as well.

I have a new thread in mind so I will see you up top.

Thomas

Yes, shorting rings reduce distortion. See the link below for more information:

Ever since last year's Great Plains Audiofest, I had been planning to evaluate B&C drivers for the Audiophile Series or for something in between that and the Professional Series. I got busy with the 12π basshorn sub and the Prosound Shootout, and didn't have time to get around to it until now. But I really like the sound of B&C components, and I'm not sure what direction Eminence is taking with their Magnums, so it seems like the timing is right.

keep us updated- I've looked at the Box 15 design they have before, and it looks pretty good. Uses the 3" voice coil driver, but for SET that may be good trade-off for the extra few dB's it gives in efficiency. Supposed to be very nice, but I've never heard them. Eminence definitely has a proven commodity.

Eminence is good, I've use them for decades and been very happy. But I'm not sure how committed they are towards their models that have a shorting ring. It costs more to machine a speaker with a shorting ring, and there is more engineering involved. Eminence has changed their line and may be reconsidering their position towards making drivers at this performance level.
