Hi, thanks for the photo, now I know how to build the box, but djk told me my 515B has too low Qts to use in this vented box, so I ask him to know if it is possible to enlarge the box until to 150/200L ( total about 250L) like the Altec VOT. I'm waiting for his answer. Walter

Hi D-Man and IndyKlipschFan, thanks for your answers. In the past I tried some subs, but it was almost impossible to find the right position for it. During these holidays I'd like to build two vented boxes. I hope to report positive impressions. Merry Christmas Walter

Hi djk, I live in Italy and it is the first time I write in this forum. I have a pair of LaScala's (a bit modified design as you can see) and a pair of Altec 515B 15"'s and a pair of 421 8H's. The 515B sounds faster and louder, ma with both drivers the bass is dry and not deep. So I have thought of your reflex box to add to bottom. What internal volume do I consider for the 515 (and for the 421 too if you think this is a better choice) and for the dimension and lenght of the reflex port? I use biamping (Audio Note Kit one for the highs and Adcom for the bass), a passive line filter only for the bass (I lower the coupled capacitor for the highs), and an Altec 288 with 311 horn. Thanks in advance Walter Creati
