Thinking of adding a Titanic 15 to an existing enclosure

[JeffKnob]

A couple of years ago I built a DIY subwoofer with an Adire Tempest and two PR15 passives. It was their SBB4 alignment from their website. Recently I noticed that my dog had gotten to the surround on the driver bottom mounted. I did some modeling using WinISD comparing the Tempest with the Dayton DVC and the Titanic. The DVC is almost identical to the Tempest. The Titanic gives more low end response and appears to have a very flat curve down to 20hz.

When I look at the curves of all three of these, I tend to lean toward using the Titanic. Any thoughts?

I love my Titanic. It hits like a monster. Probably because it is a monster. But if you already have an enclosure I'd consider the Dayton RSS390HF-4 15" High Fidelity Subwoofer. It goes lower than the Titanic, has less distortion and even costs less. It just doesn't handle as much power.
Specifications: *Power handling: 500 watts RMS/800 watts max *VCdia: 2-1/2" *Le: 1.00 mH *Impedance: 4 ohms *Re: 3.3 ohms *Frequency range: 18 - 800 Hz *Fs: 18 Hz *Magnet weight: 150 oz. *SPL: 90 dB 2.83 V/1m *Vas: 9.55 cu. ft. *Qms: 3.10 *Qes: .49 *Qts: .42 *Xmax: 14mm *Dimensions: A: 15-5/16", B: 14-1/8", C: 6-1/8".

But if you want more than 500 watts RMS then the Titanic is a great choice.

Thanks but if I remember right that model didn't model out in WinISD very well in my situation. I have heard many great things about it otherwise though.
