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...

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...

[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 ...

In "High End" today we can see nearly every possible Design and obviously it seems that we find for EVERYTHING a fanatical Fangroup.Be it Tonearms made of Wood, or Plastic (of course it has a different, more important sounding name), multi speaker ch...

[quote user="noviygera"]There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple ...

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="cv"]Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).[/quote]Chris,

[quote user="slowmotion"]I'm not so critical as you to open baffles for midbass, tho, in fact I think they can be made to work quite well, if one doesn't have the room for midbasshorns. [/quote]
You suggest that open baffles might be more successful...

[quote user="el`Ol"]But when the frequency where the dipole acoustic short circuit "kicks in" is clearly below the Fs of the driver, everything "dipoly" that can happen are rear wall reflections with the wrong phase, and that danger is also reduced b...

As I already have written before, I was looking at different bass solutions for frequencies below 110hz with my set-up. As of this weekend I have set-up a new solution and will be evaluating and fine tuning it for the coming days. The new bass sectio...

I see, this tri-way Quad system for sure shall be much different from regular Quas. I kind of even understand why you stay with open baffle bas to support the system’s bass. For sure it will not Bruckner-style pressurize a room as non-dipole bass wou...

I am still here still trying to work it out. Read your mid bass horns article again. Learned a bit more. You right about open baffle I once foolishly sold everything I owned to buy a pair of km30. They never sounded good until one day...

Hard to comment on this one... Seems like most everyone I talked to there hears with their eyes, and thought they were beautiful sculpture, therefore sounded wonderful... Maybe I should just be honest and say I flat didn't like the s...

I think the usage of Romys Injection Channel has misguided you to think it was implemented because of a certian lack of tone or some sterile sound, nothing of the sort, I cannot blame you for not having listened to Romys system, but theo...
