Creative Sound Solutions SDX 10" Ported with Bash 300

So it would be safe to run the HF in my current configuration, and it will be a more versatile driver? I am crossed over at 80hz and I do enjoy listening to music on the system as well as movies.

Sure, absolutely safe !

No, not more versatile than the HF. But with the tweaks for the Titanic design I PM'd you, it can be made better.

Having multiple subs is really a good thing for both music and HT use so just go with what your planning for now and then think about adding at least one more sub eventually(two more would be better, even if they are small)

Here's the pics. Notice the little dip in the titanic's transfer function chart, that means the box is too large for HF use, although fine for effects.

The roll off of the HF is basically perfect for a subwoofer.

any more questions please ask

cheers,

Nice. The HF does look better according to the sims.
One question though- In the cone excursion graph, should I be concerned that they are both exceeding xmax below 20hz, or am I missing something?

No, not really, the amount that the HF exceeds xmax is very minimal - remember that the xlim of that driver is about 15to20% more that the linear xmax limit.

For the Titanic it's xmax is around 18mm(one way) but that limit is not represented on the graph that revboden posted

After returning from a trip I finally had some time today to get the Dayton Reference HF driver into the enclosure. Re-calibrated and then did some listening. The difference was apparent right away. Just when listening to the test tone during calibration, it sounded much smoother and fuller.
Cued up War of the Worlds and went through the same scene (Alien Machine rising from the ground) at the same volume that I was using with SDX10 driver. I did not hear any distortion or mechanical noise and it shook the room like it should. Very pleased with the results now. I will have to wait to test The Hurt Locker scene until no one is home.
So I either had a faulty SDX10 or my enclosure was too big for it. I cannot say for sure, but I think there was problem with driver despite it's robust appearance.

Thanks for everyone's help and guidance.
