Or take off axis measurements. Maybe 45 degrees....Leave a comment:

I've been known to tweak a calibration file before, but it's been a while. I put it in Excel, and just changed some numbers. Or, you could ignore it....Leave a comment:

I suspect that altering the woofer filter sim for a higher xo point will take about 10 minutes. The tweeter probably needs a cap added to make the filter...Leave a comment:

SEAS recommends a minimum xo of 1500hz. If you want to play loud, it's better to cross higher. There's always compromises....Leave a comment:

I measure inside all the time. I'm not saying there is a problem, but those dips in the response might not be real. On the other hand, a mtm design usually...Leave a comment:

Do you have any other speakers that you can measure? It could be coincidence, or diffraction, but the dip between 2k, and 3k seems to be in both the woofer,...Leave a comment:

Look closer. Just 3 parts on the tweeter. Software is showing additional locations for additional parts when needed....Leave a comment:

That's still in the range of acceptable, even though tweaking may improve it.Leave a comment:

What about the acoustic off-set?
Your sim looks OK. I'd measure at 45 degrees just to see what changes. If a peak remains, then maybe try...Leave a comment:

Are these from your in box measurements?
Did you account for acoustic center differences?
I would like to see the raw measurements...Leave a comment:

I hope I didn't talk you out of this speaker. If the mid is louder, you can pad it to match, and it gives you some additional flexibility on voicing....Leave a comment:

The tweeter padding will change the impedance if it's after the xo. I wouldn't worry about it as long as you can measure the response. The sim may not...Leave a comment:

(See filter transfer function on lower graph. ) Sometimes the woofer filter boosts a little too.

Here's a random example.

I would suggest playing with the diffraction and room boundary simulator. Location in the room plays a role. The response at 20" from the wall is...Leave a comment:

I believe that most of the step is below 200hz. I'll see if my software will sim that. Plus, if you are close to the floor, it will lose almost nothing,...Leave a comment:

The potential problem will be that the mid, and tweeter can't keep up. Also, the speaker impedance may end up at 4 ohms even though the drivers are 8...Leave a comment:

So, when you start measuring, and assembling a xo, will you do it where you can play music on one, or both speakers quickly? When I work on a xo, I listen...Leave a comment:

Looks like the tweeter padding needs some adjusting, but the woofer response looks like an easy spot to start when you get parts.Leave a comment:
