yes martin, they were designed for the woofer of the left speaker to fire to the left (and the right to the right) so they are both firing "out", or away from center. But this is a guideline, not a rule. they can be switched so they fire in towards each other. I have read accounts from others who experimented with the placement of side firing speakers and in some rooms, firing "inward" worked better. This works because low frequencies are highly non-directional. so their volume does not attenuate off axis. it is common for example for a subwoofer to fire down, towards the floor.
@@henrydegroh2341 Thank you for the clarification. I currently play around with my new living room set up since I also have side firing towers for my home Cinema but sadly no Henry de Groh's 😁. I have 2 towers for the front and 2 for the surround. They are from acoustic research. But I think the model was only sold in Germany before the company vanished. Got them cheap back then that's why I took 4 🤭. Now since I got a new Marantz receiver to replace my over 20 year old Sony I must say the difference is spectacular good after the audyssey multi point measurements and it's auto adjustment. Finally their 25 cm side bass plays really well. They have a 10 cm bass reflex port at the rear not at the front. The front contains 2 mids and one silk high in a d'Apolito configuration rated at 180 watts RMS, 91 db sensitivity and 6 Ohms, 28 to 20khz. I btw have angled the speakers to have them point to the sweet spot of my couch. Not like in your video example setup with the 90 degree angle. I guess it also makes a difference for the bass reflection. The rears basically are cramped right onto the wall since I wanted to have them as far as possible from the listening position.
@@Martschy That's ... strange that they would put the port at the back. I would think having it front ported would... be more reliable. yes, playing around with speaker placement in the room can pay off; sounds like it did nicely for you ;-)
@@henrydegroh2341 I don't know but back then It was kind of more often seen that the ports had been placed at the backside. Currently you see more on the front for sure. Acoustic research ar 150 5000 is the speakers name.
Those AR speakers you have are super good. I have always been a fan of Acoustic Research. I like the MTM on the front, but I don't know why they are so far apart; literature says it's better if they are as close as possible.
So the bass faces to the left for the left and to the right for the right? Towards the walls?
