Home Speaker Asylum

General speaker questions for audio and home theater.

Lambda TD15, handmade mid, Raven R2 tweeter


Bass looks like Lambda TD or TDX series. If xover points done well, the low mounting will not boom and will deal with limiting floor bounce (reduction/reinforcement of specific frequencies)

Hand made midrange is interesting. The pic of the unpainted midrange MDF ring looks like a Audax PR170M series, but the metal film cone is clearly hand made.

Clearly a Raven R2 tweeter.

Overall, depending on the midrange, this could be a very moderate efficiency speaker, easily in the 95db range. Interesting that the sidewalls are made of at least 12 ply birch ply (could be 17 ply). But ply all the same. Not strictly a negative thing, just interesting.
