Hi motokok. The problem is that the port needs to be the same distance (IMO) from both bass drivers. That's why SEAS have put it midway in the rear of the box. There's no room to the side of the tweeter on the front. Here's what I suggest. As the port length is just 130mm there is ample room if it is mounted at mid height on the side of the box so no change at all is required then to the excellent design! Yes, this is unusual, but it is a perfect compromise. * The vent would see the free air to the side of the speaker. I would "hand" them so they could be arranged either way as a pair...thus venting inwards to the centre area or outwards. One way might sound better too, so it would be useful to have a choice. * Remember there are many LS designs that have woofers in the side of the box so a port must work OK... Never seen it done, but maybe it's never been thought of before? I would have no qualms about building a design with side shooting bass ports.... it must be better than rear firing ones. 🙂 PS... If the port length of any design was very short and width permitting, why not use 2x smaller ports opposite each other for the tuning?

After the "Go West" album, I have just finished listening to another classic 80's album: ABC "The lexicon of Love"... never have I heard so much detail and depth before from this CD. The sound works perfectly on the Bragis. It's as though the brilliant Trever Horn used them for his mastering of it. It's strange to think that all this detail had been lurking in the CD ever since it was made back 43 years ago in 1982 and only a few percent of all its listeners would ever know... https://www.discogs.com/master/71286-ABC-The-Lexicon-Of-Love
I played this two years ago for the 1st time in ages, then again in December over a discussion with an old friend. I didn't put it under critical listening, I just played it for nostalgia. I will go back and check it out. I know it was sonically good and there is some clear punch on the bass but I never gave it a hard listen. So I will do that. Oh, Trevor Horn. What can we say about him? I will go out on a limb and say he was instrumental in shaping the landscape of popular music. If Michael Jackson were the King of Pop, then Trevor Horn would be the engineer of Pop Music.
Did you know that video killed the radio star?
Hi. Thanks for replying to the ABC suggestion. I did listen again yesterday, and I have to say it sounded much brighter than I thought it did the day before. Maybe my ageing ears where slightly stuffed up then. maybe the last 2x tracks are best? However, it still sounds very good with that 80s style especially with its excellent growling and fretless bass, and the synths layering the deep background. I think 80's "New Wave" style was the pinnacle of "pop" music. So original and so inventive and so tuneful and most with complex bass lines. So much choice. It died when rap music took over. Now everything is either a pale copy or just pap. No worry though. I love classical and modern jazz mostly with the occasional return to the older stuff. PS: yes Trevor Horn IMO is one of the best producers. He originally played bass, and it shows on most of his creations. There are so many excellent albums and most use low bass against synths to create so much colour, texture and excitement.
