+2 I also agree. I mentioned the sealed option just in case a smaller box was a plus. -
There's another option! This option doesn't play as loud as ported, but goes as deep. I modeled an RS270P-4 in 1 cu-ft sealed. The f3 is about 62hz. When...Leave a comment:

I have a W7 machine. I keep it off line. I don't want microsoft screwing with it. I have a cloned backup hard drive too. I bought a chrome book for online...Leave a comment:

I know you want small, but how small? Can a sealed 4", or 5.25" be an option?
I was looking at bluetooth, and there are multiple...Leave a comment:

Wolf is right Drjay. If you were to use a 4 ohm shunt resistor, and feed this speaker about 128w, the resistor might get slightly warm. The woofer on...Leave a comment:

My gate comparison was misleading, so I removed it. I need to measure something with peaks, and dips, and do the same comparison. My flat response simply...Leave a comment:

Try using smaller resistors for the tweeter padding in your sim, and see if that works too. Drop the 10 ohm down to about 4 ohms, and the 15 ohm down...Leave a comment:

What does the front side of the tripod look like? Wide flat surface? If you are curious enough, you could hold the mic by hand at arms length, and see...Last edited by rpb; 01-19-2020, 12:07 PM.Leave a comment:

I hope I'm not annoying you with so many questions. Your measurements look usable already. They will need a slight interpretation to overlook the ripples...Leave a comment:

I didn't expect to see ripples at a 300hz gate setting. How loud are your sweeps? Are they loud enough to need ear protection, or be annoying without...Leave a comment:

The plate amp can extend the f3 by virtue of the low-pass filter. The "normal" f3 of this driver in a sealed box is about 61hz. Now it's at...Leave a comment:

Looks better. Here's how to improve it a little bit more. (Using these measurements, not new ones.)
Change the graph to range from -5 to...Leave a comment:

You could just put one in the room, and tweak the adjustment knobs till you like the sound!Leave a comment:

So, all measurements were taken on that speaker baffle?
I see a couple ways to improve the measurements. Tilt the tv screen such that the...Leave a comment:

If you could take a few pictures of your speaker, and measurement setup, there may be something obvious that is causing issues. I'm not trying to make...Leave a comment:

The plate amp unfortunately has a built in high-pass of 20hz! I sure wish that was set much lower. The box software shows the response with the high-pass,...

I discovered something else. I was in a hurry to try the amp, and I already had the rs270p in a sealed 1 cu-ft box. (Two way with H26 tweeter.) I hooked...Leave a comment:

My room is no larger, but has minimal furnishings to get in the way. If I measure with the speaker on it's stand, (roughly 33" from side wall, and...Leave a comment:

Here's an example. This is a speaker I'm currently working on. Top trace is the woofer without a filter. The lower measurement is with the filter. Note...
