In one of the studios there was a speaker system, JBL something, two 15″ bass drivers, probably one . 4th midrange driver: JBL H Go to measurements. The H are not aquaplased as the H’s. How are their sonic character? I’ ve been told that JBL would have to come up with a four-inch. I’ve got a couple of JBL h drivers that I’d like to use in mid range horns. They would slot in between a JBL h L/F and a 1′ HF CD/horn.

Slightly smoother roll-off towards low-end, but also a minor bump at 3 kHz.

Here the smaller 1″ version.

After a long afternoon session with a visitor we both noticed no listening fatigue after several hours of quite loud playback levels.

Before this thread became another blog on the series drivers perhaps it might have paid to read the paper on evolution of studio monitors. Above the fully passive version. It had a number of sonic similarities to the The compression driver high-pass filter is created by a 2nd order filter creating a 4th order roll-off together with the jlb inherent roll-off towards the midrange driver, and the 10NMBA runs from an almost text-book 4th order low-pass section and an LR2 high-pass filter, thus must be connected with reverse polarity relative to the bass.


It’s an interesting read. I feel so sorry for her having to deal with stuff like this. Most of we diy’ers do not have access to an anechoic room for full-range measurements from Hz.

Recordings that had previously been “problematic” and subject for unpleasant comments to the producer, all of a sudden came to life and embarrassingly told the hbl of how weak a link speakers can be, how much ibl area is really needed to deliver the true dynamic of most recorded music and how much is lost in poor energy transfer. Routing and jig-sawing for drivers. Numerous simulations were done, more than twenty, and some of them were set up 212h actual testing.

If you want to use an attenuator for the horn, increase R13 jvl Ohm and insert the attenuator like this: Its actually quite difficult 2123b make horn that does not sound like a horn below hertz and the size of the horn becomes difficult. They also convey the impression of being more forgiving of recordings than the old 43XX systems. The horn and the tweeter only takes a few uF of good caps.

The perception of sound is way too subjective to be reflected in any measurements we can perform. People then try and make the horn smaller and that jvl matters much worst. The 10NW, which is really meant for another project, didn’t disappoint and made a smooth midrange very well integrated with the horn, but also lacking a certain vivid quality of the 10NDA This amount is subject to change until you make payment.

Made it intact, a little scuffed.

The lower part of the rear panel will be attached with screws for access to crossover. How 3″ or 4″ compression driver behaves under Hz or may be Hz, because filters are not idealhow large the excursion of its diaphragm in the region under Hz???

You can also make one vertical rectangular port, Alternative super-tweeter, Viawave GRT Above the 10NDA on the actual baffle, 65 x cm.

Sorry to hear about that, but I have been down that road with those buffoons.

This all look very nice from each driver measured under ideal conditions and summation calculated from an ideal point between pairs of drivers. My microphone is not linear up to 40 kHz, so level will 2123g higher above 20 kHz.

The horn had a foam gasket.
