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.

Looks like a very well behaved driver. Doing dZ on the two drivers reveals the bjl driver being mm behind the midrange driver from mounted on a flat panel. Some will say yes, some may say it all depends. The high side filter reponse was equalized and not taken down as low. Adjust to fit your choice of panel thickness.

Cover all internal panels except front panel with 8 mm felt material. The midrange is as dynamic and transparent as can be and the compression driver delivers a resolution and lack of distortion that leaves even the best of domes behind. With these date put into the simulation software, we can manage a flat frequency response from connecting the horn with opposite polarity relative to the midrange, where a 4th order filter would normally require same polarity.

Fairly flat frequency response that shouldn’t cause much trouble in crossover design. This listing has ended.


The research in that paper gave rise to the – Bi radial monitors. The item may have some signs of cosmetic wear, but is fully operational and functions as intended.

Don’t forget to mirror cabinets! In laymans terms a well integrated 2 or 2. Now, attenuators may have a bad reputation because the wipers may get noisy over the years. In one of the studios there was a speaker system, JBL something, 1223h 15″ bass drivers, probably one passive, 10″ midrange driver, horn-loaded compression driver and tweeter, probably Bass performance is highly dependent on in-room placement of your speaker and the same speaker can be boomy in one place and lean in another.

Values come with the kit. Yeah, you’d think they were being made off world or something Took damn near a year.

Many people put way too much into these graphs and my comments here are only meant as warning against over-interpretation.

Maybe if I extend the basement, there will be room Price to pay is size – and weight, not to forget! There are 0 items available. Marking drivers and preparing for routing.

My favorite are the Arrays but I won’t be getting rid of the any time soon. The longer fog horn sounds even more horrible crossed over at hertz. Above the horn on actual baffle. Was I seduced by the jgl

Drivers alone are some EUR. It took me a long time to take my eyes off the 10NDA midrange driver, because it can do wonderful things, but I was never happy with the crossover complexity to make the driver do what I wanted.


It 2123j the weakest link in the S The kbl 43XX can become tiring after a while as we know but they are fun all the same. Make sure to mirror the braces!!

If you want to use an attenuator for the horn, increase R13 to Ohm and insert the attenuator like this: But trying to find a listenable 2 way is like pulling hens teeth.

Skip to main content. This even from speakers twice the building price. The fact remains though that some people will always feel that there should be some kind of midrange driver between the woofers and the horns in systems like the S, S and E2.

Using the FA allows you to get watts for the bass driver, or you may choose to run the FA as a two channel amplifier and have one amp running the bas driver and the other amp running in flat mode for the MTT section via the passive crossover. The super-tweeter runs from a 3rd order filter creating a 4th order roll-off, creating the best integration with the compression driver 2213h a single coil provides a 1st order filter creating a 2nd order roll-off.
