I know that it is offtopic on thread but have you saw the Ricci sub designs?

 

[BP1Fanatic]

Hey BP what are u using now, subwise i mean

 

[BP1Fanatic]

I still have the same subs I built in 1998 and 2012. I finally painted the 2012 LAST Saturday per the wife's request. We moved into a smaller house earlier this month.

Before and after.

 

[BP1Fanatic]

Here is 2012.

 

[maxolini]

Looks awesome! what design is that one and what do you use to drive it

 

[BP1Fanatic]

Here is the 1998 sub.

Before and after.

 

[BP1Fanatic]

I did this during covid.

 

[maxolini]

nice builds man, so what are the design/name of your subs

 

[BP1Fanatic]

A pic got cut off!

1998 = 2 12's in a BP4 enclosure.

2012 = 15" negative flare tapped horn or Tapered Tapped Quarter Wave Tube or Pipe (T-TQWT or T-TQWP).

Car = 12" BP4 enclosure.

 

[BP1Fanatic]

T-TQWT.

 

[maxolini]

That resembles the PAL12 🙂

 

[BP1Fanatic]

PAL12 = March 2013.
I started designing my T-TQWT in January 2012.
