Re: Definimax 4012HO - End of Life
I don't remember specifically what made me pass on the Faital drivers for three Pi model, because I looked at many midwoofers back then.
In many cases, the problem that keeps a driver "off the table" is the basic electro-mechanical stuff. T...

Re: speaker plans 4 pi
That's awesome! Hope it was a good deal for both you and the seller.
The deal with the center channel is the port can be removed for aesthetics. There isn't a benefit when doing so, in fact, there's a slight penalty. But only slight. The spectral ...

Re: Am I in the Right Place?
Going a little larger - to 5ft3 - adds a smidge more bass and remains properly damped. You can model it and see what I mean, or build a physical model and measure it. Going smaller reduces bass output, but again, remains properly damped. So that's a u...

Re: Pi3 vs Pi4
The posted measurements are for the fully upgraded models, but the differences in response aren't major. The benefit of upgraded midwoofer drivers is mostly reduced distortion because the upgraded drivers have shorting rings.
That's not the case with...

Re: My 3π adventure
Wow thank you for all the comments Wayne!
I had the idea that SBIR can be reduced by moving speakers away from back walls (which without a sub would be unfortunately around 2.5m). Thick absorption behind will also help.
But I am intrigued by your su...

Re: My 3π adventure
Measured in-room, I think your response curves are pretty good. This is typical in-room response. Looks to me like all is working as designed.
In-room measurements show the room more than they do the speakers. But having a waveguide speaker really ...

Close to finished 2 Pi Tower
Here's the fruit of some labor.
I used 3/4" MDF everywhere except the front which are 1" I adjusted to keep the same inside dimensions. I also adjusted for those plates I put in the bottom. I just hope I adjusted enough. for so...

Re: Recessed baffle and speaker grills
It does create a diffraction edge, which is more significant for wider lips than narrower ones, as you would naturally expect.
However, in my experience, the adverse effects are marginal for lips that are 3/4" or less. I give this measurement em...

Re: 4 Pi Build in San Luis Obispo - Parts Arrived, Got a Router Jig
Nice work so far. And man, I hear you about the "things get in the way" issue when doing projects. I always have several projects underway, and like you, I have several disruptors. But I always try to remember that a mountain is climbed one ...

Re: Smaller 3 pi construction?
Of course, a loudspeaker like you've described could be designed and I would expect it to be great, if done properly.
But don't modify the cabinet dimensions without acoustic testing, and specifically pay attention to the lower midrange. That's what ...
