Exploring Purifi Woofer Speaker Builds

[Boden]

Yessir!

 

[tigeranand]

all are doing 2 way bookshelf same type nothing revolutionary. how about omni speakers and soundbars

Boring that is, demonstrating how conservative and copy-paste based high end audio is anno 2024.

Hmm, makes it even harder to wait ;-)

Space is reserved ;-)

 

[lrisbo]

good to have an upgrade path😀

By the way, I dare to see any polar plot of the PTT10X !

 

[lrisbo]

you mean beyond what is in its data sheet?

 

[jcga]

Yes, at least +/- 90° in 10° step would be greatly appreciated

 

[lrisbo]

ok thanks. that will be possible when we install a new mic rig in our chamber (the one we use to do the tweeter polars in 5 deg steps)

 

[jcga]

Nice thank you Lars

There are exceptions though, for instance I would not call these Sun Audio standmounts conservative or copy-paste based.

@jcga

Any particular reason why you’d like to see polar measurements of the 10” woofer? Do you have an application in mind?

 

[jcga]

@tktran303

I'd like to see the polar behaviour around 1-2.5 kHz to evaluate the possible use in a 2 way loudspeaker

 

[tktran303]

In a IB in Purifi’s hemianechoic chamber:

A narrow baffle ~11” wide would improve dispersion a bit, but not enough to make a big difference at 2KHz.

I’d cross the PTT10.0X to closer to 1KHz than 2KHz…

@tktran303,
I've already the 30 & 60° curves that Purifi kindly provided to us mais I don't think it's enough to decide it is worth it to buy a pair at that price for testing... By the way my target Fc is 1250 Hz probably LR8 linear phase

I’m going for serial numbers 0001 and 0002

@lrisbo

Are they available without faceplates, with compact neo motors ?

 

[lrisbo]

yes we plan to sell them without faceplates as well. They have a neo motor but the huge neo magnet has 80mm in diameter so I would not call it compact…
