A Thread for those interested in PPSL enclosures

[djk]

Looks good, more efficient.

Will require a different box and port, I 'll run it tonight.

Thank you once again, Djk.

Should I use the same plenum size you provided for PD.1550?

May I possibly have your views regarding my queries at post #659?

 

[Ikabod88]

Hi Djk,

I decided to go with the PD.1550 specs you've provided rather than the Fane as I have 2 ready, but might hurt my pocket later on if I decided to expand to 4 cabinets.

I attached the link for the cabinet, if you have free time, please check the specs for any corrections.
External dimension L33 1/2" X H 21 5/8" X 23 5/8" (approx.) as it was drawn in metrics 85cm X 55cm x 60cm.
I will be using 18mm/13ply Russian Baltic Birch and will be built fully rebated.

Plus, I enclosed another 15" PPSL driver candidate, somehow similar with the OEM 15629 and Kappa Pro 15. maybe you can also provide the best cabinet dimension for this driver (15FH500).

FaitalPRO | LF Loudspeakers | 15FH500

Djk,

Will (2) Two PPSL 2X15" cabinets perfectly match (2) Two Sls920 per side outdoors?

Thanks.

Photobucket does not work anymore (they want $500).

Try Imgur: The most awesome images on the Internet for your images.

 

[Ikabod88]

Hi Djk,

I'm sorry about that.
will try the imgur.

Thanks.

here's the link,

..or you could just post the images here, so they're not reliant on another site being available in order for them to be displayed in your message.

 

[Ikabod88]

Hi Brian,

Thank you for the tip,

But I don't have any idea on how to post pics directly here at the diyaudio forum?

 

[Brian Steele]

Under "quick reply", select "Go Advanced", then select "Manage Attachments". The rest should be self-explanatory.

 

[Ikabod88]

alright, will try that.

Thanks a lot.

 

[Ikabod88]

Here's the PPSL 2 x 15" (for PD.1550)
- bracing wil be as described by Djk and wil have pocket handles.
- will utilise the PPSL upright for singles, sls920 pole mounted on top.
- external dimension H 550mm x W 850mm x D 605mm.

Thinking of building it in double baffles to add strength,

Any suggestions and comments will be appreciated.

Thanks.

Do the 2 drivers share a common volume?
If so, is the connecting area large enough not to choke the air flow ?

 

[Ikabod88]

Hi Scott,

I didn't quite understand your question,

Are you referring to the area behind the Plenum?

 

[Scott L]

Yes. And now that I have looked at the sketch, my question is already answered !

looks great !!

 

[Ikabod88]

Finally, wood panels are ready, just the spare time to build this 2 X 15" PPSL.

This will be loaded with PD.1550

 

[globalplayer]

This will be loaded with PD.1550

Excellent choice.

 

[Ikabod88]

Excellent choice.

Thanks,

Pretty excited on how a 2 X 15" PPSL loaded with PD.1550 sounds, although I'm aware that this isn't the best driver for this enclosure. I hope it will somehow meet my expectations.

I haven't read this entire thread, but this seems like a very intriguing design.

However, kind of large & heavy. Has anyone tried this in a 2 X 12", PPSL ?

Yes, and in this thread somewhere c/o Norman Bates, IIRC. They were Dayton drivers - I don’t think that particular model is still manufactured, however. I could be wrong - I didn’t see it on PE any longer last time I looked.

Edit: Norman’s POST - my mistake: 4 x 12”
