How To: Mirror EQ with VituixCAD

With VituixCAD, we have the ability to provide a mirror EQ function, that can then be passed to APO EQ for active processing. This allows for a speaker's frequency response to be fully compensated for without requiring many bands of parametric EQ.

VituixCAD Process

---

Connect each driver and EQ blocks in the crossover section as shown. Ensure that the active peak/notch filters are “shorted” so that only the G(f) block is directly connected to the driver. Three PEQ blocks are show,...

With meticulous passive filter design, it may be beneficial to hear the result before spending money on crossover parts and putting in the time to assemble the crossover. Fortunately, with VituixCAD and EQ APO and filter can be simulated digitally. This process can simulate multiple drivers simultaneously, one driver for each output on a soundcard, for example a 7.1 soundcard could simulate a stereo 3 way system utilizing 6 channels.

Note that an emulated passive filter will reproduce...

Hi Guys,

I need a hand to fix a crossover for a set of B&W DM602 s2 speakers. I picked them up as a "for parts" sale, and since they had been so badly mistreated I thought I would help them to feel better. So far tweeters repaired, but I need help on a crossover. The two...

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.

Hi all! I just recently delved into the DIY audio world looking to build some nice tower speakers for my apartment at school. I settled on the Anthology speakers. Will update as I assemble the cabinets. I am probably going to take them to a family member who does custom automotive painting to give them...

Like others, I caught the DIY bug after building the classic Overnight Sensation MTMs. I realized that store bought speakers in my budget just wouldn't make me happy. I wanted some real tower speakers that wouldn't leave me needing more. I stumbled on the Anthologys page but never found much for feedback...

Hello all,

I started with Paul Carmody's Overnight Sensations several years ago, building them with my father as a project. It was a lot of fun, and so last year we began planning the next project. After quite a lot of forum browsing and research, we decided on Jim Holtz and Curt Campbells'...

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...

EDIT: As conditions around the build changed and a back injury. The goal of the build changed to a slightly modified normal Statement II build as my back problems prohibited me from doing the work required for the first intended build.
Changed made to the statements are the following: Slighty...

Hello all. I recently discovered this forum in my search for info on the Statement II's. I've been wanting to do a DIY build for a while, and one of the features I knew I wanted was a ribbon tweeter. I love the EMIT tweeter from vintage Infinity's (rocking the RSIIIb's as mains and RSVb's as surrounds),...

Hi All,
I am building statements II tower. I currently have Klipsch (RP 160M) bookshelf and I find it very bright. I went to burning amp event in SFO last Nov and met some nice people and heard some nice amps/speakers and realized what I am missing in mid range. I didn't want to buy another speaker...

Hi All,

Like many audio hobbyists, I’ve been reading this forum for some time. I’m thankful for the generosity and knowledge that is shared here.

I have some Polk RT7 bookshelves that I’m rebuilding into a 3-way (over time, the spiders on the midbasses come unglued from...

Perhaps less of a build thread and more of a setup thread as the build is more or less finished and I'm not much of a cameraman. I still need to do the veneer work, but was eager to listen for a few weeks before I began that.

I deviated from the prescribed plans in a few spots; I shortened...

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...
