tbh you could get most of the performance from just a dual flare conical.
Very cool!

Particularly in modern rock/pop music, the kick is often mixed with a lot of boost around 3-5kHz to give it a clear attack, so yes, that is a frequency often considered when EQin a mix. In the more extreme cases, it becomes a very distinct slap as in some of the faster metal genres.

To that end, many mics intended for use on bass drums are designed with a contoured frequency response to get part way towards that kind of tone even before touching the console's EQ knobs. This example is form the Shure Beta52:

Thx David, now I got the whole story. Makes more sense to me now.

Found this; kick drum has even higher frequencies then a violin....

I'd disagree with that frequency chart a little bit - (if close mic'd in particular) a violin will have some frequency content at least an octave higher than that from the bow drawing across the strings.
You wouldn't notice perhaps if you're used to hearing them from a distance, but if you've ever played the instrument you'd know it was missing.
Indeed, most acoustic instruments will have partial content like that up to at least 10kHz, often higher. It doesn't form part of the note per se but does represent a lot of the detail and "texture" of the sound, to use an untechnical term.

Ok, so I've been looking at some of the Faital drivers and are thinking along the lines of the following.

Woofer
Faital 12FH520
Ported box approximately 60 litres and tuned to 50Hz
2x 4" round ports. From memory I think the first port resonance frequency was calculated to be around 680Hz.

Tweeter
Faital compression driver.
1.4" with Polymer cone.
Options are HF142, HF144 or HF146.
The HF1440 looks to maybe be a better choice, however they don't seem to be available. Does anyone know where they can be purchased from?

Driver Spacing
I can get the center to center measurements between woofer and tweeter to a minimum of just under 280mm and are aiming to get them as close as possible.

Crossover
Initially I'll be aiming for a crossover frequency under 1kHz if possibly.
Crossover will be active; likely via miniDSP as I already have one.
Crossover frequencies, slopes, etc are therefore flexible and will be determined later.

Anyway, that's the plan so far. Please critique.

The HF1440 doesn't seem to be available at all YET. You are definitley not the first one waiting for this to be avilable !

…. and people like us are definiltely not those who will get the first production ones …..

Regards

Charles


P.S: I currently use the HF146 on a 18sound XT1464 waveguide and I like it a lot. With your 12" you could use a smaller horn/waveguide than I with double 15".

PPS: This one got a lot of positive reviews lately (not everyone will like the Altec inspired retro design though): Model 12 - dynamikks

I have a pair of Fostex FW 305s woofers used for about two hours in the original packing boxes.I am in Australia.
