Saint-Saëns planar- AKA SMJ-40- time for a project now?
This project concept has an unusual history and evolution. It started out in early mid 2021 based on the idea of a short narrow column bass system, originally targeting the recently introduced Dayton E180HD-44.

Considerations for Peerless 830452 Multiple Compact Ported Subwoofer Build
Looking at the other subwoofer threads going right now, I am under the impression this is one of the few places to go for sensible input on subwoofer designs. I have been slowly selling off my larger speakers and subwoofers in favor of more modest equipment to put in the living room. Dedicated theater...

2021-2023 Isiris Update
For various reasons it makes more sense to me to have a succinct new thread covering the investigations and updates this year for the Isiris. Only a few key items that will be addressed right away, but there might be more soon if the negotiations for early samples of a new midrange are completed. ...

Steve's been bugging me for a center channel design...
Sometimes I wonder if developing another center channel design is a bit like doing another 6-1/2" two way- as I think Dennis Murphy said once, another 6-1/2' two way is not going to be a ground breaking concept...
But it can be made interesting... (but that's a different day and a... -

Just a heads up that between Curt and Efalegalo they have come up with a modification to the original crossover that works better with the new production AST2560's currently shipping.

The Bordeaux - Crossover Help Needed - DIY Gurus please chime in
Hi All,
I just recently completed my build of The Bordeaux and needed help with crossover issue I'm having.
See attached picture of the frequency response. I have a massive dip in the 1.25Khz - 4.0Khz range.
I've checked the crossover a 100x.

Feedback on MTM planar enclosure/driver selection
Looking for feedback on this crossover I've been kicking around for my cousin who really wants a planar tweeter.
It's an MTM with 6" Dayton RS150 mids and a planar tweeter. I want to use the Dayton PT2C-8 but it has an aggressive roll-off after 10kHz, which makes me want to redesign... -
How to Design a Crossover from Scratch
For years, I wanted to design my own speakers, but didn't understand the intricacies that went into it. For all I knew, you bought a 2500 hz crossover from parts express, picked a woofer and tweeter that looked cool and went at it. It wasn't until i really got into DIY speaker building that I understood...Last edited by 123Toid; 14 August 2017, 16:03 Monday. -
Why doesn't anyone use loudspeaker management instead of crossovers in high end desig
I've read it improves phase shift, delay, voltage ringing in capacitors, inductor compression, complimentary induction between inductors, compression from heat generation in resistors and capacitors, variances in component values and decoupling of the amp from the driver. Also each amp only amplifies... -

Prior to working on this project, has has completed a pair of full range and 3-way speakers (With a pre-manufactured crossover for the 3-way - It did not sound...

How to Learn Passive Crossover Design?
What are some good sources online to learn about passive crossover design? Right when I think I'm beginning to figure it all out, I learn something new (Baffle step diffraction, driver impedance matching). I'm just beginning to understand the purpose of L-Pads and Zobels but have no idea how to calculate... -
Isiris evolution to Osiris Jr? Summary of Isiris build and new update
The Isiris never got it's own build thread, being the culmination of the "Three Way Evil Design Study" - it didn't seem very urgent, as only two pair were expected to be built world wide, due to availability issues with the NS12-513-4A woofer. Of course, that part of the design can be redone...
