The resonance frequencies are basically set by the box and vent dimensions. The magnitude however is impacted by the position of the drivers and vent... -
That's actually not quite true. The pipe resonances are also influenced by the box's internal dimensions. You can see this effect if you use a tool...Leave a comment:

Neat solution there, I like it.
I tried making a variable volume enclosure some years ago - basically a bucket with an interchangeable baffle...Leave a comment:

My guess is that the horn is not properly filtered, so the speaker has a midrange peak that probably sounds pretty bad.
As the others said,...Leave a comment:

Oh well, it was just a matter of time. The Ministry of Health just announced the first case of COVID-19. Apparently someone that arrived on-island on...Leave a comment:

Good point. Electrically the x-over is definitely 2nd order - there's a cap and coil in the tweeter circuit and cap, resistor and coil in the woofer...Leave a comment:

So, I'm doing a few more measurements before I commit to this renovation project. I'm getting some weird results when I measure the original drivers...Leave a comment:

Estimating low frequency performance using in-room measurements
I've been fiddling around with a technique that I don't see discussed often here, but it could prove useful for "removing the room" from low-frequency... -
That banner pic was from our "Eleventy-Eleventh" (1111) Run. While I was hashmaster, I got bored having a big run every 50 hashes, (1000,1050,...),...Leave a comment:

Well, I ordered two of the Defined Audio HT-200CCs and I'm convinced now that it's the Paramount HT-200CC with a different grille :-). I see the price...Leave a comment:

One of the (minor) concerns I have is that the impedance of the x-over drops to 3.3 ohms at 6.5 kHz. It's back up at 4 Ohms at 5.5 kHz and 9.5 kHz however....Leave a comment:

Just an update: I received all of the drivers on Friday and of course went to work trying them out and trying to come up with a few x-over options. I've...Leave a comment:

Thanks for the responses.
If it helps, the "MTM" in question has 3.5" bass drivers (if you can call a driver with 115 Hz...Leave a comment:

MTM x-over design question...
When designing an x-over for an MTM layout, do you go for the usual deep null on-axis with the tweeter connected in reverse?
I'm asking because...
