集まれ！塩ビ管スピーカー is a Japanese community website for people who enjoy building their own speakers, especially designs made with PVC pipes and other tube-shaped materials. Since its launch in 2009, the site has provided a place for speaker builders and audio enthusiasts to share ideas, practical know-how, projects, and listening experiences. While its central interest is DIY pipe speakers, members are also welcome to discuss other kinds of speaker construction and audio topics more broadly.

The site brings together community contributions through project galleries, discussion boards, comments, member diaries and blogs, news, and image sharing. Visitors can explore completed builds, follow works in progress, read about audio equipment and music, and find updates on related events and contests. The community also publishes participation guidance, including frequently asked questions, usage rules, and membership guidelines. Its content is intended to grow through members’ individual contributions, creating a shared resource for people interested in hands-on speaker design and audio.
