Not quite true. With a properly-built TL, you can control both the magnitude and location of in-band peaks and dips caused by vent resonances and their... -
What are you using to measure impedance? If DATS, the voltage drive is likely too low to cause the tweeter any damage. The "Qts" for many tweeters...Leave a comment:

That's why I use an external USB sound card for measurement purposes.
I also use a USB MIC. I think you lose some ability, but nothing of...Leave a comment:

You don't need a lot of power for doing measurements with REW (frequency response) or DATS (impedance). My 8" tablet had 2GB of RAM and an older...Leave a comment:

I actually use TWO computers for the usage you're describing. There's the "workshop" PC that's used for measurement purposes, and a minitower...Leave a comment:

Seeing that my PITAs use the same bass driver as the C-Notes in a similarly-sized enclosure, I decided to compare the sim'd responses of the bass driver...

Some more measurements. These show how the speaker's response with the current x-over varies over a listening angle of +/- 45 degrees. A small but noticeable...Leave a comment:

My solution? A Dayton DSP408 between my computer and the amp driving the desktop speakers. I got tired of my software EQ settings on my PC being wiped...Leave a comment:

All sides are lined with Sonic Barrier 1/2" Acoustic Sound Damping Foam and Dynamat Extreme, and it's half-stuffed with polyester fiberfill. I had...Leave a comment:

That hole in the response may be a feature of your subwoofers, or it may be a feature of your room
If you can, pull one of those subwoofers...Leave a comment:

Just a further update - I decided to go with the Peerless tweeters for the reasons previously mentioned, and adjusted the x-over to suit. I let the woofer...

Those are the parameters I measured using DATS. The semi-inductance parameters were derived from the measured impedance curve....Leave a comment:

It's the Infinity 122.7W car audio 12" driver. I used to have them in my car, but replaced them years ago with Alpine Type Rs. They've been sitting...Leave a comment:

FWIW, I've never had an issue with PVA clue. I've got smaller cabs held together by PVA glue only. Larger ones are glued and screwed.

It sounded fine for the brief period that I tested it.

It won't be possible to produce a portable box with a comparable FR with this driver. The box will need to be very big, and the FR will be even more...Leave a comment:
