    Yamaha JA-0801

    I am super curious about having one driver play 400-4000hz. This aligns with where our ears are sensitive to decay and flip to just caring about sound pressure. My hope is that this sucker lives up to the specs and decays to -25db in about 1ms. The mid will be crossed to the bliemsa t25b and...

    SB Acoustics SB13PFCR25-4 COAX 5" Paper Cone Coaxial

    I am looking into making a low-cost coaxial with this driver. My aim is $200-250USD per speaker. Google found this post: https://www.diy-hifi-forum.eu/forum/showthread.php?14743-SB13PFC-25-4-Coax The measurements look like shit. After a little VirtuixCAD tinkering, I could see most of the...

All of that sits on the top of a sub that is on a stand. …It is a stacked 3way will sit on each side of my desk. I wanted a nice set of speakers for...

    BlieSMa T25A-6, T25B-6, T25D-6, T25S-6 - a comparison of dome materials

    https://hificompass.com/en/reviews/bliesma-t25a-6-t25b-6-t25d-6-t25s-6 I thought this was a really neat writeup about some high-end tweeters. For me, the most interesting part was how silk performed. T25A-6 = Aluminium + magnesium T25B-6 = beryllium T25D-6 = diamond T25S-6 = silk Thanks...
