Your contribution is very interesting. It is a point of view and that is what it is about, enriching ourselves in the space that a forum like this offers us. But 99% of the recordings are mono approximately from 60 Hz down except extreme cases of more or less old recordings. Let's take TAKE...

Let's see: I tried with up to two subwoofers, but despite measuring better, the bass was, I don't know how to say... "not compact", even though my Swiss army knife (DBX Venu360) gives me the opportunity to vary the cut, phase, time, etc. of each subwoofer. The secret is to dedicate an extra...

First several considerations: - My method is self-taught and unorthodox, but it measures me and sounds good. - My room is asymmetrical and I don't know how it would work in symmetrical rooms. - Regarding your question "Didn't that result in putting too much strain on one of the speakers by...

I had a huge null around 60Hz and I fixed it by equalizing both speakers as shown in the attachments. In short, it is about preventing both woffers from "fighting" where they are out of phase (generally in asymmetrical rooms like mine) by applying deep PEQ and with Q 16 on one speaker and...

I have a JBL S3100 that has the same compression driver. I filter them through a DBX 360 VENU, but taking REW measurements with its asymmetrical horn is a real pain.

Extra bonus: this is my cat Mephistopheles (aka Satan) acting as Wally and bass trap. Where is Wally? He hates REW sweeps, but loves CAT Stevens' music.

This is my thing. The music I listen to is mainly pink noise and REW sweeps, and very very very occasionally rock music.

I got these little coaxial speakers from the 90's but it sounds awful. I have measured the tweeter at 1 cm. with and without your passive filter and something seems to be wrong. The measurements of the other speaker are similar, but not identical. Is the dried ferrofluid to blame? Thank you.

Amir references his passive and active speaker tests to his Revel passives. I leave it there ...

Hola amigos, Quería interpretar a Greg Timbers (en adelante Dios) y me salió mal. He intentado REW midiendo la respuesta de la bocina a partir de 650 Hz (punto de cruce declarado de 750 Hz) para implementar los filtros sugeridos, pero suena horrible. Estaba midiendo a 1 metro y también en el...

Yes.

Yes. In preamp Mode.

I SINN, I bought one of these to active amplify the horns of my JBL S3100. The woofer will go on with my trusty YAMAHA P3500S and whatever God wills...

You play hard, mate!

It doesn't turn on when receiving any signal, but when you turn it on manually, it remembers your last input selection.

DBX 390

Total disaster, but we are in a scientific forum and I had to prove it scientifically. The speakers danced to their own beat and he wasn't about to lose them around the house. Note: My health is fine.

Attention!: As you can see in the attached photo, tomorrow I am going to place a camera wheel under my 57 Kg (125 lb) JBL 3100S to isolate it from the ground. The floor is driftwood. If the camera wheel doesn't blow up and give me a heart attack, I'll tell you the results...

30 years ago I changed my PROAC STUDIO 100 for JBL 4330, nothing more radical! I never went back to "conventional" speakers and just traded these in for my current JBL S3100. I don't know why, but the horns+big woofers+high sensitivity sound like "music" to me and the conventional ones sound...
