JohnA Posted February 27, 2017 Share Posted February 27, 2017 The better alternative, since you are willing to go bigger, is a longer bass horn. That would get you deeper bass. An 18" driver would not increase the efficiency much. Do you remember the LB-76? It's a J horn. Turn the mouth backward, add a V to turn the sound forward, or brackets to space it away from the corner the correct distance and you'll have a longer, larger bass horn.

carolinacat Posted March 2, 2017 Author Share Posted March 2, 2017 I'll look into it thanks. Also with the 18 I'd loose more upper I'd imagine like the lascala bin will do. Quote Link to comment Share on other sites More sharing options...
moray james Posted March 2, 2017 Share Posted March 2, 2017 Italian version for 15 inch woofer http://web.archive.org/web/20000617112202/http://www.ciare.it/pdf/MYPROS4-5.pdf for 18 inch http://hornplans.free.fr/dth118.html another approach http://hornplans.free.fr/fh2.html http://hornplans.free.fr/fh1.html http://hornplans.free.fr/1850.html as you can see the cabinet gets a lot bigger but does not go any lower and these are all designed to be used in multiples to get a much larger combined mouth size which is necessary because the horns are very short. For its size the LaScala is about as good as it gets and the Peavey FH1 is a slightly larger slightly better version of the LaScala. Dual twelves will push more air than a single fifteen you can look at the Jubilee design in a single fifteen the widest range that I have ever found is a fine design by Ernst Georg Beck called the California. others here will have designs for a clone of the Jubilee. http://www.egbeck.de/speaker.htm Quote Link to comment Share on other sites More sharing options...
