Hello! I’m an amateur woodworker and have built up a decent amount of tools and skills in that department.

Home theater subwoofers have always fascinated me and the PSA Power Sound Audio series has gained the praises from so many folks here.

I need advice on building my own pair of dual 15” subwoofers for a large room. Using the TV24NEO by PSA as reference.



Here are some things I narrowed down.

  • Speaker Brand: LaVoice (Model TBA)

  • Box Style: Dual subwoofer design with front rectangle port. Similar to PSA Ausdio design.

  • Music Style: Electronic, Jazz, Sade, Enigma, Dance, Trance. Only watching movies 20% of time.

  • Room Size: Large 13 feet wide X 25 feet long. 14 foot ceilings

  • Current Mains: JBL R700s powered by MAC 250w power amp and NAD preamp.

  • Power Amp For Subs: CROWN XTI 2002. One for each subwoofer. 2 Total

Speaker Connector Style: TBA

Exact Speaker Model: TBA

Box Design: TBA


Your help with box design and selecting proper driver for my room setup would be much appreciated.


Thank you

I would consider a dual-opposed subwoofer (DOS) design, similar to what I have built (also with Lavoce drivers):

Thread 'Lavoce SSF153.00 15" based dual opposed subwoofer project' https://audiosciencereview.com/foru...5-based-dual-opposed-subwoofer-project.51178/
 
Thanks for your input! Im not opposed ( pun intended ) to building a dual opposed subwoofer. How did it turn out!? Any changes or overall feedback on the project?
I have built another one:
Thread 'Using four bass guitar drivers to build a dual opposed subwoofer project' https://audiosciencereview.com/foru...build-a-dual-opposed-subwoofer-project.56479/

And another one:
Thread 'Another 8" dual opposed subwoofer project' https://audiosciencereview.com/foru...other-8-dual-opposed-subwoofer-project.55078/

And another one:
Thread 'DIY 2.2 living room project' https://audiosciencereview.com/forum/index.php?threads/diy-2-2-living-room-project.57939/

I guess I don't need any further comments
