cardioid

There seems to be a bit of interest in cardioid subs. Dr Toole thinks monopole sub should be the norm for home use. There are others who obviously disagree. I am also interested in figuring out what differences cardioid subs make. Since I like playing with modeling/simulations, I thought...

This is a comparison of THD at 96dB SPL average of current cardioid models. If you know of other current speakers and measurements, please post them in this thread. A few notes on the chart above: GGNTKT M1: Data converted from %. Average SPL was 95dB. Sigberg Manta: Data converted from %...

Hello everyone, I'm trying to understand how simulation works in VituixCAD. I started with the measurements on the IEC panel provided by the manufacturer, I then rechecked the measurements with the Trace tool to integrate the low-frequency range and the diffraction of the panel using the Merger...

I have been working on this project for a long time, and finally finished it. The concept is simple: a 3-way speaker with full-range directivity control. Design and optimization of waveguides was done with Fusion 360 (modelling) and AKABAK (simulation). I will not bore you with the details, but...

Disclaimer#1: Klippel measurements from us (the manufacturer), not independent measurements. Disclaimer#2: Cleared with moderators that it would be okay to post this thread for specific discussion around the measurements and technical aspect of the speakers. For discussions related more...

Hi ASR, it's been almost 2 years since I first heard about cardioid speaker design being implemented in mass-production (it was during D&D ad campaign I guess). Last year I had a chance of listening to 8c and KH310 (w. 750 sub) side by side along with some Amphions, and while I disliked the"out...

First off, I want to temper expectations, I'm certainly not a cardioid radiation expert - but will do my best. I can only touch on a few topics and if something interesting comes up I will expand the post if necessary. Index 1. Does it work? 2. Comparison speaker with slots to "normal" speaker...

(This product is now in production and sales, to be found here: https://www.sigbergaudio.com/products/sigberg-audio-manta-1-active-speakers) It's time for a new build/prototype thread! Thank you to everyone who followed our previous threads (Inkognito subwoofer, 10D subwoofer & SBS.1 Active...

Good day everyone - So I’ve been looking into various methods of applying a cardioid response into different designs - things like resistive enclosures, active methods with rear drivers, and such The thing that concerns me is that I’ve always wondered if it’s actually worth the effort - I’ve...
