[quote user="msaudio"]If you look at the picture second from the the top, you will see 2 woofers mounted in front on the baffle, notice a 2 piece horn from the baffle. Klangfilm never had such a horn, they would start at the baffle and curve out. The...

[quote user="Markus"]These speakers were not open baffle. [/quote] Actually they are. They might not look like open baffle but they have all negative conceptual characteristics of the open baffle. I think to properly evaluate what those type of the s...

[quote user="Romy the Cat"]our logic is correct but you refuse to see the whole picture - this is the biggest mistake the admirers of the open baffles do. Let trace the entire process. You grow the size of the baffle in order to keep the speakers to ...

Hi,I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. I am using a 12" JBL midbass driver (~100dB sensitivity) in a 50L single driver Marshall cabin...

Well, it has been said a lot about the Open Baffle concept at this site. The new concept that you introduce into a discussion is price. Yes, the today’s Open Baffles are pricy and snobbism along with a sense of faux superiority that the Open Baffles...

Yes, I did have a look at the photo series. Many of these folk are serious about their amplifiers, or at least put a lot of energy into them. Too bad they did not invest equal amount of effort into their speakers. Open baffle has become very popular ...

[quote user="Joe Roberts"]The Western Electric L-9 in Munich was/is an infinite baffle design. The 754B woofers are in a sealed enclosure with a front horn. There is no possibility of cancellation between front wave and back wave of speaker, so I wou...

After a few hours of playing strategizing I just literally just sitting in the chair, doing nothing and just looking at the speaker I find a brilliant idea how can completely recover it. I mean completely. I'm going to send to my cabinet maker a Sket...

Thanks Romy,Yes, I received your advice in the past privately regarding proper size for 1808 enclosure, and I thank you for pointing me in right directions. Yes, sealed box is simple calculation using e.g., WinISD. I am experimenting with&n...

speaker’s surface for a small result.[/quote]Yeah, but plywood is cheap and the result is audibly noticeable. Baffle extensions were recommended for all of the Altec VOT cabinets too. Make a big improvement for cheap ...

Weren't these speakers (at least in Germany) normally used built-in (infinite baffle situation)? And I don't like the word "open baffle" because it can mean anything. It reaches from quasi-IB like proposed by PHY-HP up to that more and more crazy con...

Gentlemen:I assure you, Infinite Baffle bass simply has no peer. Yes, you do need specialized drivers. The Infinite baffle bass concept is so old, it's rarely even considered anymore, plus, you are indeed married to the installation....

Not the same size, shape or volume of the original baffle/cabinet, but I appreciate that you want to keep the appearance you've imagined, and this seems like the "easiest" way to do that. Good luck using a reciprocal saw to cut out the 6" laminated b...

You know, extending the front baffle without making it take up too much space? Many people use the ubiquitous single driver on a narrow front baffle augmented by back-folded wings on piano hinges...I like those three mids; what are they doing -- canc...

Murat,
I am not qualified to talk credibly
about Tapped Horns. I know that they get a lot of traction now around audio
people but I am, without listening a good example of it, am not so warm to the Tapped
Horn idea. The comments of yours that y...

[quote user="Joe Roberts"] The L-9 enclosures were wood on all sides. Sealed box. No ambiguity here.Wings were common on theater speakers for mid-bass reinforcement. Plainly audible improvement on these and, for example, A-7/A-5 VOTs. It is equivalen...

[quote user="oxric"] I like the idea of angling the enclosure, although I am not sure about the idea of the lowest drivers firing at the floor...I would use a series of modules each containing two tightly fit drivers which would fire parallel to the ...

Jbl came out with a new type of horn design a few year back and it looked like it had alot of good features. The top wall of the horn was curved up while the bottom wall was curved up then down very steep and it was still a 93-46 degree horn. You cou...

I've been thinking abut this question form several angles. Firstly practical.I thought I'd better see what low bass sounds like. And to get some idea of placement possibilities. So I set up my LS3/5as in the (rather cold) un-converted barn. Couldn't ...
