Re: Pi 3 subwoofer
Your results look good, and you could expect a nice little subwoofer from that 1ft3 box. It isn't very large and yet has 35Hz f3 and 22Hz f10. Port area is 12in2, so you can make it 3.5" square and 5" long.
That woofer is suitable in tiny ...

Re: Pi one port
Thanks Wayne, i will add the extra 1/4 inch.
Can you shine some light on the method of checking the Helmholtz frequency when the cabinet is finished?
Thanks for answering on a Sunday.

Re: Pi one port
Well, it was designed for a port that has uniform cross-section. Flared ports are good for reducing turbulence at high airspeed, but then again, the port on this model is so oversized it'll never even get close. Still, I think you'll probably be OK. M...

Re: 4Pi speaker tweek
I talked to Nick while he was contemplating this build. I told him the same thing I tell everyone that approaches me with a mod like this.
First, if you change the physical relationship between midwoofer and tweeter, the crossover has to be redesigne...

Re: Power/pre amp question for Pi Speakers
It sounds like you have thought it through and have a reasonable plan. If all the amp channels are able to be run independently - without some kind of processor - then you should be able to use them. Basically everything but the subs are run full range...

Re: Use the woofers, but scrap the box
Honestly, I wouldn't go the fudge/fit route. I have spent a lot of time dialing in these designs and to modify them throws all that out the window. Box dimensions might seem trivial, but in a box this size, standing waves form in the lower midrange so ...

Re: High-pass on the 4pi?
High-pass at the Helmholtz frequency of the mains. The multisub configuration is not limited to direct radiators, but can be employed with hornsubs as well. Delay on the mains is really used to match the acoustic centers, to compensate for the extra de...

Re: Powering my PI Speakers
I think some would go as far as doubling the amp power level, but remember that this is all about making sure the amp doesn't clip. Your speakers will handle the rated power, all-day, every day. But if you go much beyond that, the speakers will be the ...

Re: Powering my PI Speakers
A few thoughts, in no particular order:
I'd run each of the mains on their own channels, and I'd run the surrounds in series / parallel if several were to be combined on each channel. Most prosound amps are pretty tolerant of their loads, but I'd sti...

Re: Alpha 10 modeling
Like I said, I think your model is probably pretty good at this point. While I wouldn't generally suggest designing a speaker to operate near xlim full time, I would say that exceeding xmax in this speaker isn't terribly objectionable. This speaker doe...
