Interesting Horn info

Posted 11th July 2013 at 10:55 PM by DougL

In this post the User clams that the Compression driver Atlas PD5V is a derivative of the WE555, which was good down to 100 Hz

There was also mention of an AES paper on how to create a phase plug for a cone driver.

Based on Romy's ideas on a mid-bass horn, This might cover down to 200 / 300 hz to transition to a Tapped horn.

My Horn Project

Posted 21st January 2013 at 11:13 PM by DougL

I have 2 Horn projects.
I would like to try a
SEOS / Econowave style with a SEOS 12 / 15 and a Denevo 360 compression driver.

I also want to try a LTO style 3 way

I am trying t do this inexpensively.
Looking at JMLC 400 1.4" mid-ranges
Radian 636 CD
B&C DE10 or B&C DE7 CD
JMLC 1000 or JMLC 1400

Looking for an approprate woofer.
The GPA 515 is beyond my means at the moment.

JBL 2226H are also reputed to be great

The TD15M has a following.

I have a DCX2496 and 6 channels of 30W class D amplification.

miniDSP tools

If I ever have my DCX break and need another XO, these tools look like they make miniDSP a real choice.

JBL L100 Homage

Posted 20th November 2010 at 04:55 AM by DougL
Updated 11th February 2011 at 04:50 AM by DougL

I got into audio my freshman year of collage in 1973. While I hated the "West coast sound",
The JBL L100 looked great, and had a great woofer. It is also higher efficiency than most.
HTGuide did a Thread on redesigning the XO and made a very appealing speaker.
I looked up the woofer and its 88 db efficient. So much for perception of efficiency.

My thought was to design a 3 way speaker that is ultra low distortion, 50Hz F6, and 93db efficiency. Borrowing the L100 concept, Driver compliment 12" woofer, 4" mid-range and OS compression driver.

There are at least 3 drivers in the 4" class with 93db Audax HM100Z0 4" Aerogel Mid-range ,
Fostex FE126En 4" Full Range
I already have and love MP14RCY/P in ob, but they are only 90db sensitivity.

The B&C 3/4" or 1/2" CD look like they might be a perfect match. Sure beats a 2" paper tweeter.
Even a B&C...
