We have two models with different upper bass horns, one is indeed a 140hz horn (77 cm diameter) and the original, bigger horn at 110 hz (92 cm diameter) Both tactrix both made from the same materials (MDF) and finished in the same automotive finish.T...

I think we have to subdivide bass into upper bass from 100hz to whatever your midrange does and bass under 100hz and then maybe infrabass.
Front loaded upper bass horns are fantastic and I would say if you never heard one, you really nev...

HI "Hifiordie" I want to tell the readers here that this guy is seriuos and has some serious talent.Unluckily for him he has been bitten by the same insect that got us and is obsessed by horns, please do listen to Romy and try to balance your life b...

Dogs are not what they used to be, I remember they used to lay and eat and not require too much, now they get jealous, they bark back at you and the will shit in front of your speakers if they are not happy, at this point in my life I love my kids, l...

My bad experience was mainly for aesthetic purposes with just a couple of drivers, so clearly misaligned. sorry for repeating the comment.
The biggest tower of bass drivers I have used was 4 tubes, dynamics was good but the difference I found aga...

I guess you have listened to it but when I don't align the separate bass cabinets they fight each other and I get terrible bass....
|
Hello Anthony,I did experiment with metal tubes for bass in a sealed configuration as you are planning. The weight of them, even made out of thinner than you would like steel, is prohibitive. If you make them out of aluminum pipe, then it could be b...

Congratulations on your new house!
I wish you a lot of love and success in there....

About vibration, there is this technology championed by AR9 a few years back and now seems to be everywhere. Opposing woofers, the force cancelling technology says the movement of one driver gets cancelled by the movement of the other and no vibrat...

Sounds Very interesting, If you can change the loose insulation in there for Cellulose, it is supposedly much better sound wise than fiberglass. It would also help to avoid leakage of bass to other parts of the house through the attic, if that is p...

Having a big window in front at night it becomes like a big mirror, some might get self conscious about it! JA The thing about glass is that it eats up bass and reflects highs like crazy, having said that, some of the best rooms I listened to, had...

Congratulations! I wish the best for you and your family in this new move.
The little apartment you had downtown sounded phenomenal with the arrays doing bass. Maybe just double up on those? Taking the infra bass from them will let them breat...
|
Just a couple of notes here. In my experience downfiring, or upfiring for that matter, woofers is not a good idea, the coil has to lift the full weight of the cone in order to move it and this slows things down, instead of just pushing them back an...

I tend to like drivers with plastic suspension. Radian makes retrofit diaphragms for JBL with plastic suspension, maybe they will help you achieve the tone you are looking for.
Extensions are easy to machine out of aluminum, even wood and they can ...

I love late night listening sessions, low volume but still enough to wake up kids. Most surely they will wake up and cuddle next to you while you are listening, you will have this great image of your kid falling asleep on your lap through the whole l...
|
From what I gather the JBL 2169 driver is an 8" cone speaker with a sealed back chamber. If this is so it was designed for a specific horn. It shall be used in that horn or a very similar one. The back chamber should be tuned/designed for the horn ...
|
For home use almost any driver will go lower without burning up.
If you want specs, BMS and B&C will give you the right specs.
And then there is the tone...
I had 2490 play down to 200 hz in a 100 hz horn, of course they would only go up to 1 kHz ...
|
If you have a huge 2 meter long horn and like what it does from 70hz to 300 hz that is a very difficult range and really simplifies (ja) the rest of your channels.
Having a horn to play from 300-400 hz is not a big problem or a big horn, a handful o...
|
Get your Upper bass horn sounding properly first, this should be a lot of fun,
Play it by itself untill you get the perfect sound out of it
adjusting the back chamber volumen changes the sound a lot.
Why use a different driver form 2400hz? Do...
|
HI Romy,
As you know I have 2 kids, one is 8 and the other 3, they grew up around my system too, and they learn where to move where to touch and what not to touch, and it is great they have Access to good sound.
At the hardest time, when you cannot...
|
I agree Steverino, IMHO Bass in the most tricky part of audio!
A couple of things I found out that help. Most importantly, Time Alignment! Not just between the channels crossing right to the next frequencies, but the whole system should be time alig...
|
It remains hidden better.
Bass only completes the midrange without calling attention to itself.
It adds color and overtones better to the midrange, and when it is called for…
It appears faster, and more drastically than the other xovers.
To be ho...

Romy,
Thank you for sharing the link!
The second part is better!

We only use the Beringher for bass under 100 hz, driven by the main amp.
We tried a lot of different solutions, including analog active xovers, the DCX is cl...

Generalizations are Hideous, and there is nothing else in the article...
|
Hello Gera,First thing I would do is get rid of the active Xover, in my experience they mud everything up. preamps are very important and this is like a double preamp with a lot of gain stages. For bass you can maybe use it. I use a separate Xover...
|
Tweeters are a real mistery. Some should sound great and they dont, and some never will.I think you do need a lot of dynamics even at 10khz in order to get those sparkling highs that really jump out like the real cymbals and other crashing metals! O...

Most Show videos are made with no preparation, maybe only some quick light fix, like please turn those on or off.I think the second type videos as Romy defined them are pretty useful, just a nice Showcasing of the gear to see what is out there, how ...
