[quote user="Markus"]Re-reading, I realise you stated your preference for a sealed bass array only in relation to Dreyer's bass horn, not to bass horns in general.[/quote]Markus, it is not only about the Dreyer's bass horn. It is about lower bass...

I'm wondering has anyone actually tried using the pro sub horns, similar to EAW LA400 (about 36"x36"x24" or similar size). There are a few different products available, such as Fitzmaurice tuba, EAW, based on a 15" or 12" woofer. What are your experi...

Bass horn sub now fitted underneath, with false shelf added for the righ hand side mid bass horn.
The extra height is good....90cm to floor for tweeter, 110cm for the mid horn.
Just a nice BIG wall of sound...wit...

[quote user="Kerry Brown"] Yesterday a friend of mine brought over a CLIO analyzer and we graphed the impedance vs. frequency. I was surprised that the subhorn measures like a ported box tuned to 50 Hz ! [/quote]Yes, this all is very explainable. The...

Jessie,
Perhaps if you search something in the throat jungle you might fish some interesting results. You see, optimizing the driver to throat transition you might get some HF out of upper bass driver. But besides getting more HF there is something ...

Here's how I will initially position the mid bass horns. The imaging is excellent....though I give a little away in dynamics. The 12-inch B&C drivers kill the puny 8-inch Fane drivers for this application. Well done John Inlow for this design. I ...

Romy, I'm very proud that you are following me and commenting my achievements.I just don't understand why you are doing it in a manner that you are the one and others are idiots and morons. If you don't understand others, you can ask them questions. ...

Hi Romy…and fellow audio nutters. I’ve bitten the bullet, and shifted from BLH to front-loaded. Yes, I was an idiot, a moron for not doing this sooner. My project is ‘humble’ by Romy’s standard…but I feel it meets the following objectives I h...

Romy, Is there a consistent effect from too large/too small and how is it analyzed? Working on a new horn that I had turned by a fellow in Hungary and have made my back chamber so that I can easily manipulate the volume but have no idea of what to e...

audiofilofine, you need to form a question in a format that would indicate you do the your do some homework. To bulb or even to design 20Hz horn is complex task and it usually made to the specifics of the given circumstances. As rule to use properly ...

Romy,
More to come soon but a couple comments regarding bass horns ( and one on Tractrix horns ) :
The Edgar Seismic subwoofer ( 18" JBL E155-4 hyperbolic-exponential folded horn, 40 Hz Fc ) works very well in my room - much better than the 1...

I pretty sure we are talking the same things, ie
Phase shift = frequency dependent delay - spreads a signal out
Geometric arrival delay is linear phase - delays all frequencies equally (obviously)
I was just hypothesizing that a slightly ge...

Hi all
Thanks for your thoughts, Romy.
In my view the least controversial of your “THE PROBLEMS WITH HORNS” cycle. Or, to put it another way, I agree with most of it.
I'm not so critical as you to open baffles for midbass, tho,
in fact I thin...
