Looking for recommendation on horn type for 2 12" speakers

thachur · 16th November 2010, 05:57 PM

I have 2 of these and would like to build a box or two for them. They will be used for "Future Bass" type electronic music so I would like them to get down to 32ish.

bandpass horn?

FUNKTION-ONE : OFFICIAL WEBSITE = MB212?

Any ideas?

Those drivers dont look ideal for a horn design, fs too low. However, one never knows. Download hornresp, input their TS data, click on Tools->System Design->With Driver, say "yes" to the next question, input your desired bandwidth (ie. 32-150 or so) and click on ok. Then the program designs the optimal horn for them. Beware: It will be big! Then proceed to tweak the parameters to achieve an acceptable tradeoff between optimal performance and size. Lastly, you have to fold the horn, build it, and be happy. Total time investment: HUGE, fun factor: also huge (if you are a nerd^^). If not, buy speakers

An alternative would be a tapped horn, however this type has no wizard which designs the beest parameters for you.

yea mavo, these aren't the best drivers for a horn.

However, with that in mind, my big box jbell's set of four tapped horns is workable, and does get to the desired goal.

You MUST high pass at 30hz, and stay under 300 watts per driver, coils in series, drivers in parallel. Also things get ugly up high, cross no higher than 80hz...
