I except suggestions and critique. I live in Turkey and I am not living in a city, I live at the coast. It is not possible for me to go and experience most of the stuff first hand. There is no one really interested in horns or have multi-way horn systems that live close by. I travel to concerts and listening sessions. Those crossover points are starting points for me. They are not set in stone. I will measure each driver in its relevant horn but I had to start somewhere. I knew I wanted horns. I knew I did not want to push my horns to their lower and upper limits. That was a deciding factor for having five (or six) channels. I knew the biggest upper bass horn I could have in my room and one that won't need a time delay. These meant I would have 4 channels from 160hz. I had some drivers and I heard some drivers. Out of the ones I heard and liked, or have been suggested by people with opinions worth listening to, I started simulating these drivers in various horns. I also read what type of horns are more suited more so than other for certain frequencies. I then though about putting these horns together, and what height it would be and how far I need to sit. These kind of dictated what I could have in my room. I can not think my speaker system without my room, they will have to work together. For example, I simulated the supravox in a cf110 tractrix and I really liked what I saw. I heard the sound of this woofer as well. I decided this is a combination worth trying. So I ordered to try. This was my approach.
This is why I did not have designed crossovers beforehand. I also have minidsp to test crossover points and slopes before committing to building the passive components. I have built a few differenet horns to hear how they guide the sound. I built various speakers just to learn about slopes, drivers, minidsp etc. So I am open to suggestions and critique. I have been reading your site and your approach to bass. I have friends in Denmark so I can get Scanspeak drivers. I saw Scanspeak 30w/4558t00 and if I build a similar cabinet to yours with just 47litre sealed compartments, it seems they can play down to 38hz. I can have 6 sealed compartments in each cabinet for reaching necessary efficiency. Keep their amplifiers in the cabinet behind the upper bass horn that has 3 different compartments which are for crossovers, back chamber and bass amps.Romy, May I ask you why have you decided to play your upper bass horn lower than its ideal limits. Doesn't group delay rise and phasing occur. Is it not possible to play the bass arrays up to a higher freq. I know any solution is in some way another problem. What kind of problems made you cross your upper bass horns that low. Although I miss out on concerts and audio enthusiasts of the city I am not so sorry. I am a musician and live with another musician friend of mine. We have a studio and have a lot visitors at our house. Yesterday we had a Brazilian girl flutist and singer and a Mexican guitar player. I recorded them too. It is nice to be able to record people in the space we listen to music. They liked the sound of the listening/main room more so, so I set up there. When I was studying at the university, my department (interior architecture) and music department was close. So we have a lot of classically trained musicians who come to listen to and play music
