What makes you close the sim and open a spreadsheet?

[Hdale85]

I've been working on a loudspeaker design tool for my own use for a while now. It covers enclosures, crossovers, diffraction, measurement import, and so on. I mostly started it because I was tired of moving numbers between three different programs and a spreadsheet just to answer one question.

Hi
Some years ago I buildt the Wavecor Ardent.
Build thread: https://www.htguide.com/forum/forum/...h-center-build

As you may notice the idea was to also build a center channel. But then life happend, and the years has gone by....

I've been thinking of making a set of gift speakers for a while now, something I could give to friends and family that wouldn't break the bank and was reasonably simple to manufacture quickly. In lieu of designing something for myself I think I have settled on the Mechano23, designed by Xmachinik. His...

Teaser alert!

I have extended the VHex+ power amp design of Valery Zaichenko into the VHex_step-up design, 50-70W into 8 ohms.
Step-up features lower distortion, current limiting, output muting, etc., while still having a relatively low parts count.
Have prototype PCB boards...

I've had a few inquiries about this part- Looks like it could be useful, hope it is, but hope is not a strategy, so I ordered a matched pair to test.

This article will describe the fruits of my efforts to build a moderate sized speaker which might be moderately above average in performance for a basic two-way system. I desired a speaker like this both for my own use in secondary systems, and to fill a need for some friends, who desired fairly full range response (i.e., “it’s gotta have good bass”). Also, though I have access to a good wood shop, many potential DIY enthusiasts may not, so I hoped to use a modified...

Good morning! I'm starting to plan out a set of speakers for my goddaughter (and her older sister) as they get older. Average age of the two of them is like....4 years old right now. Probably won't start on these for a bit yet, but I want to start collecting parts and watching for sales and stuff. Stuff...

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.






This dual magnet long excursion driver seemed...

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...

Hello Everyone,

I am looking to build a speaker with an 8" woofer and a 4" tweeter in 1.5 cubic feet or less. These are the constraints, please don't make suggestions on what to try outside these guidelines.

Because I do not know which are the best drivers to choose,...

Hi all! Does anyone perhaps have metric drawings or a 3D model they could share? It would be greatly appreciated and save me a lot of cash!

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. ...

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. Meniscus has also committed to testing every AST2560 driver ordered to assure the correct crossover parts are included...

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.
