How low does the BD15 go with your enclosure (BD-Design)

Hello finecognac,

I recently measured my BD-15 respons with a professional B&K analyser. The -3 dB point is at 29 Hz measured at my optimum listening position. The BD-15 is in a 160-ltr reflex enclosure comparable to the Reference. Below 29 Hz it falls of quite rapidly. Before I used an Eton 581-11 (if I remember correctly) that goes down to 21 Hz according to its specifications (in a 110 ltr. box). There is almost no difference in how deep both units sound (the Eton just wins).

The longest diagonal in my room starting from the speaker cone is just over 6 meter. This gives a lowest room resonance of 28 Hz. It will be very difficult to get a good response down to 20 Hz in such a room. So if your room is larger, you are lucky. Final remark, the Eton and the BD-15 have the same price tag, but the BD-15 sounds MUCH better, i.e. less distortion, more speed and dynamics.

Kind regards,
Eddie
