Hard to say. You can just feel it more now. Probably over a large portion of the frequency range. I had others compare as well and they also could, including the wife, and she normally can't...

That's native response. It should be linear, but you can also EQ the sealed enclosure. At lower levels the equal loudness curve will be a large factor as well, rendering any comparison mostly...

That's normally what you'd think, however after going ported, even after eqing flat, I noticed more tactile feedback.

320 is too rough and will leave some deep scratches, would not sand that rough. If you're wet sanding after spraying, I'd start with 800. I sand until all previous scratches are gone. Sometimes...

That's 2 ported compared to 2 sealed. Add 12db to go from 2 drivers to 8 drivers, assuming you still have enough power. I didn't save the ISD files so not recreating atm.

I'd just go ported instead of PR. Save the cost/headache. Most around here don't use the 13w7 since it's not really economical. Low displacement and high price. Good for a car where you can use...

Fitting them is tricky. If you can fit them, need to watch your pressure levels and velocity.

You can build better than that, but similar. I did so with my 18s. Just balance out how much cubic footage you can spare and how low you want the tune. You can model it up in winisd or something...

Hitting it with a glaze after rubbing compound will clear it up a good bit. Really makes it look deep.

Can you take a similar shot to the one showing the scratches? Something seems a little hazy, might just be the camera.

All of those scratches should be gone. You moved between stages too quick. I can't tell how deep they are in the picture, but it seems like it needs more sanding.

Jumping from 220 to 1000 is not advisable, you really won't get out the scratches from 220. I wouldn't sand clear with 220. 400 at the roughest. Even then, you're going to have trouble getting out...

Oh, didn't sound like you were spraying from a rattle can. Just make sure anything from a rattle can or something that isn't 2K gets enough time to cure before sanding.

And this is part of the reason why I used the space I could for ported enclosures and not horns. This is further exaggerated with lower tuning.
