Sundown X-12 Prototype

I never said it wasn't going to be a great sub. Fs is much lower...

Fs won't play that big a part in the sub bass game either

So a sub with a 45 hz fs will play 20 hz just like a sub with a 30 hz fs?

In an anechoic environment, no, in an enclosure is a different story.

Do you listen to your music in an anechoic room?

Do you think he knows what a anechoic room is?

And the answer is no

You would be surprised what Sean knows.

Who do you think helps test and design subs with Jake?

Points. That guy.

In an enclosure, same story. A sub with a 45 hz Fs in a box tuned to 20 hz and playing 20 hz will sound like ass across the board. It will play it sure, but the frequency response will just be a gradual taper down to the playing frequency. If it were say, a 40 hz tune box, it would be relatively flat response till below tuning, where it would fall off quickly. There is a reason home theater drivers have a 15-20 hz Fs and similar tuning. Playing a full octave below Fs just won't have authority.

Do you think he knows what a anechoic room is?

Would it blow your mind if I had one?

Apples to oranges

No need to be a smart ass, I needed to clarify that looking at Fs alone should never rule out a woofer.

D4 specs with a very short break-in period :

Re : 7.00 ohms

Fs : 34.61 Hz

Qes : 0.57

With break-in the Fs and Qts will drop a bit as well.

IB install with one of these would be mighty interesting
