<No, not really.  That song's just running through my head, and so is this question.>

So's I'm looking at the specs for Dayton's Titanic MKIII....besides the price, why would it be an undersireable sub for a HW build?  Too much sag?  

How about using it for other decware plans?

Not sure how to measure the sag, or if there's a realtionship between (magnet) mass and sag.  (Or would that be voicecoil length and sag...hmmm).  

In your opinion, 2 dbs are "better" than 1 HW, but is part of that because you have 2x the number of speakers? (assume 2 per enclosure).  How would you rate  2 dbs  vs  2  HWs?

[quote author=Adrian D.  link=1156872872/0#3 date=1156874932]...one of steve's posts saying that 2 db-12s (1 woofer in each) would perform better than 1 hw with 2 woofers. [/quote]

Wow, that's a bold statement!  I'm very surprised.  I'd like to believe this, but can anybody else verify this claim?

From PE's website regarding Titantic MKIII 15's specs:

*Power handling: 800 watts RMS/1,100 watts max *VCdia: 2-1/2" *Le: 3.84 mH *Impedance: 4 ohms *Re: 3.68 ohms *Frequency range: 19-500 Hz *Magnet weight: 136oz. *Fs: 19.93 Hz *SPL: 91.7 dB 2.83V/1m *Vas: 7.79 cu. ft. *Qms: 5.89 *Qes: .41 *Qts: .38 *Xmax: 20.5 mm *Dimensions: Overall Diameter: 15-9/16", Cutout Diameter: 14-1/16", Mounting Depth: 8-3/8".

but my db12 had 1 x 12 inch driver and my hwk had 2?

60, you're experience of both is based on a car setup.

I found it.  FYI for those who don't know.

*edit*  Sorry to keep bumping my post, but according to PE's calculations, the 15" Dayton Series II (which is so popular here) has approximately 8.6% sag, while the 15" Titanic MKIII has approximately 3.05% sag.  

PE states "As a general rule of thumb, any time the sag exceeds 5% of the driver's Xmax, it's not recommended for a down-firing subwoofer application"

It looks like the Series II isn't such a good choice in a vertical HW... ???

Wreckin', I don't understand what you wrote.  Are you backing what Adrian (and Steve has) said about 2 db's being "better" than 1 dual-loaded HW?  How is a dual-loaded, magnet-to-magnet, HW not "utilizing the cone area of both speakers"?

In this configuration you must wire the speakers out of phase with one another causing them to work as one. This configuration will without a boubt give you more control and tighter bass, but you will still be using the cone area of one driver 176.71 square inches. By using two single loaded cabinets you are utilizing more cone area 226.20 inches. The difference in cone area is approximately the equivalent of an 8" woofer. Pump one fist in the air you have your HW, pump 2 fists in the air you have your Db's. Get it?
