Re: Need a replacement driver

Does anyone know who's sub that is? I guess at $25, it doesn't really matter, but if anyone knows, please speak up. The reviews seem good, but I was wondering if it would work as a car sub.

P.E. might be able to tell you where it came from. Cabin gain would boost the low end in a car environment. As long as you're not looking fore a SPL monster the sub will handle 80 watts with a hi-pass filter at 20 hz.

Re: Need a replacement driver

Well Diapers has taken precedent over a new driver this week... but hopefully Parts express will still have some of the buyout sub next week.

ANY-FOR-WHO. Since the placement of the sub in my cabinet is down firing; could any one enlighten me on how to tell if a particular driver can be used down facing with out unwanted cone sag - hence would the buyout sub be fine in this orientation. The DC250-8 never gave me any noticeable problems in that orientation. and it was like that for about 6 years.

So I am sure some of you are wondering how my 2 year old daughter got easy access to the DC250-8... Well I had it on its front side with the amp pointing up in order to clean out the dust in the heat sink. I had to run to the toilet and when I came back Esther had - with the aide of a Philip's screwdriver - nearly ripped half the cone apart. Not even the rubber surround was salvageable. She even ripped the spider and had part of the voice coil unwound. (should of taken pictures before I ripped the magnet off and tossed the basket and cone away.) I was so shocked i did not even know weather to laugh or cry. I am so glad my family forced me to attend anger management classes years ago. In some way this is my fault because not even a weak ago I cut apart a dead driver to show a curious (NON-audiophile) friend how a speaker worked - of course Esther was watching. Monkey see, monkey do. (my daughter is the girl holding the kitten in my avatar picture)

Here's the math for figuring out cone sag:

The sag should not exceed 5% of the Xmax.
