In your opinion where is the best sounding tweeter location in our s2000 configuration?

 

I swapped my door panels and move my tweets from oem spot and flush mounted them in the a-pillars. Glad I did it.

 

As far as staging goes, on the dash is the best. Puts the sound coming from in front of you. But anything will sound good as long as it's close to the factory location or higher.

 

The factory location now staging sounds abit low, it also makes the tweeter sounds too bright, and off syn with the mid woofer.

 

closest to your ears

 

Depending on the shape of your ear height cues can be picked up anywhere from 1,000hz to 4,000hz up. That means the tweeter is the primary sound source for stage height. Naturally for staging purposes you want them as close to ear height level as possible. This will correspond to a location on the A-pillar that varies a bit depending on your height. Width and depth cues are mostly in the midrange so they matter little for a tweeter. The only other thing you can vary is the direction the tweeter is firing. I find on-axis with the driver requires the least amount of equalizer compensation to get right. This will also preclude you from getting nulls and other odd cancellation behavior that you would normally get by having them firing at each other.

In short, in the pillars aimed at you.

 

Putting the speaker on the pillar is going to fire the sound more towards the chest not the ear. If the tweeter in on the flush on the dash, the sound will bounce off the windshield and hit you right in the face.

 

So you are willing to chop up the dash for tweeters but you are not willing to use a swivel cup to aim a tweeter mounted in the a-pillar? Remember sound is not a particle. Every tweeter has a power response, output is strongest on axis but there is still lots of output off axis. When you bounce sound of the windshield that sound is reflected but a lot of it is direct still. There's a lot more EQ. work to be done this way. You must have at least a 31 band graphic or a 7 band parametric to tackle the frequency response. With a parametric I think you'd prefer leaving your bands for use in the midrange anyway.

I think the Kappa Perfects I've used ohh maybe 6 years ago had some clever mounting cups. You don't have to follow the natural slope of the pillar. In my S the tweeters need the least EQ. and they are almost right on axis. All I do is boost 20khz a few db due to the natural rolloff of the speaker. Every other speaker needs really heavy EQ. work.

 

I think you missed this post by me.

No I'm not willing to modify any dash that doesn't have a mounting location for tweeters factory already in the dash, it's far to much work. As far as the s2000 goes, the best location is the factory spot. It's close enough to you that you get most of the sound but the s2000 is FAR from being an SQ car so no point in modifying much of anything for sound because the engine, wind, road, other vehicles, etc are going to drown your music out.

 

I took on the dash to mean on the dash. I guess you refer to on the dash as a-pillars as well. Semantics I guess.

Don't ditch the S2k as a sound car mate. It can be really good if you invest a lot of yourself in it. Any car is bad for audio from a technical point of view. Then again, the combination of open air, high revs, a proper chassis, and the right tunes beats home theatre for me.
