I am about to build the WO, i have already built a House Wrecker with good success. The thing is am thinking of changing is the driver.

I am looking at A 10" Titanic MkII Subwoofer 4 Ohm

Here are the specs:

Impedance = 4 ohms

Re = 3.3 Ohms

Le (mH) = 2.67

Fs (Hz) = 29.6

Qms = 7.34

Qes = 0.47

Qts = 0.44

Mms (g) = 156.1

Cms (mm/N) = 0.19

Sd (cm2) = 330.1

Vd (liters) = 617.2

BL (Tm) = 14.25

Vas (liters) = 28.33

Xmax (mm) = 18.7

VC Diameter (mm) = 64

SPL (db @ 1W/1m) = 85.0

RMS Power Handling (W) = 400

Usable Frequency Range (Hz) = 28 - 400

The PDF file for the Dayton Driver is:

http://partsexpress.com/pdf/TIT280C-4_specsheet.pdfYou people are the experts and know how to crunch these numbers. Can anyone please tell me whether or not i would be better off using the recommended speaker over this one. I am really into the construction aspect but i am not sure what all the specs really mean. (Please keep that a secret, because i do consider my self an audiophile) Thanks for any help you may provide in advance.

Thank You,
