Hello all,I'm looking for subwoofer plans for Eighteensound 21LW1400 type speaker. I can see only one plan by the manufacturer, that is a bandpass design, which maybe not suitable for outdoor events (anyway, I would listen everybody's opinion about this...). Here is the official plan: http://wizardaudio.hu/hasznos/hangfal%20tervek/bass/band%20pass/pdf/18Sound%20Kit21.pdfI need a relative easy to build plan, mostly for horns because of outdoor event, but if anybody has other good plans for this speaker, please tell me.Thank you very much
You should not be looking for speaker plans for a particular driver-but rather looking at something (driver AND plans) that meets your needs.FIRST you have to define your needs? Do you need low freq or high output?Does size matter? How simple is simple? What sort of wood working tools do you have? What is your skill level with those tools?What you are asking is along the lines of "I have a small block Chevy engine-does anybody know a good car to put it in?Without more details there is no correct answer for YOUR needs. Somebody may have something that works for them but not you.
I want it more loud then deep, but as far as I know it would be a horn subwoofer, which I don't really like. (Can't it be both: deep and loud? )
Sure subs can be loud and deep. It depends on what you consider "loud" and "deep".Why don't you like horns? You can get the most SPL for the lowest cost that way. IF designed right.
I don't like horns because which I heard (not one) I didn't like their sound. And also, it felt like they aren't really "punch in my stomach" enough. But maybe - probably - I have had experience with wrong built or just bad horn subwoofers.If somebody makes me a good horn subwoofer (which maybe will have more then 100dB sensitivity? ) It would be great.

Then you have not been listening to properly designed horns or systems that have not been setup properly.Generally the problem with horns is lack of deep bass-unless they are really large.As a general rule-horns have much more "punch" than front loaded cabinets-because at the upper end of the response there is a lot of "horn loading" going on-which means those freq are going to "kickout" a good bit more.
I think you glossed over the distortion components of reflex loaded subs. The 2nd & 3rd harmonics will be louder than the fundamental frequencies in the program material, especially when the rig is pushed (and most subs are pushed hard). I know you know this, Ivan, and low distortion horn are part of what you guys do at Danley. I've heard several comments about Danley subs that *complain* about the lack of distortion because the listeners are soooo accustomed to hearing it they believe it's really part of a designer's intentions, rather than an unfortunate artifact about which little can be done.
