Hello guys, i'm building some new loudspeakers for my HT. So looking in some speaker got this one DG-403 Full Range from aliexpress. And searching in forum found another guy who made an bookshelf for this one, using a TL system, he used a plan from Planet10 Slim Classic GR dFonken125 2v01b. My knowledge in reading data, and frequencys etc is a bit limited, since i started in this world of audio some days ago. So my plan is using 2 of the speakers in an center loudspeaker. But building 2 of the bookshelfs maybe will be very large, someone can recommend an plan?
Hi, you see, that's a fullrange speaker so...
FIrst, the most sensitive data you need is...sensitivity! How loud it plays given a standard signal ( 2.83 V = 1 W on a 8Ω load) and measured on axys at 1 m.
Second, you better NOT put two full range speakers side by side because it causes interference, indeed usually you may see two midwoofers (filtered) side-by-side and a tweeter in between ( or a compact mid-tw assembly for the most luxurious center channel) . The phenomenon is well known, it happens between all the sound souces and in particular a loudspeaker which has more than one moving membrane must be under observation. Positive interference also is used when two speakers side by side take advantage of it. Obviously if they are aligned orizontally or vertically, something changes.

This way is something i'm planing to. But my knowledge is limited, so planing something from zero is hard to me. So if exist some building plan will help.
