Ok im fine tuning my setup atm.

When in the drivers seat it appears that the majority of high frequencies of 10k and above are coming from the opposite side.

However when sitting in the passengers seat the tops seem to be coming from the drivers side horn :confused:

Ive used time alignment on the horns and it seems if i delay the furthest horn the treble normalises. Usually you should delay the speaker closer to the listener.

I'd rather not use any time alignment at all from left to right, and just use to to blend the midbass and horns together as im runnign active.

What can i do??

[Pulse-R]

maybe the angle of the mounting (vertical).
if you drop the back of the horn down a little, the dispersion will rise, and the driver close to will be pointing at your head instead of your chest/neck

I don't say I know horns, but my suggestion is based on what I understand of physics

[Bassaholic]

Which horns do you have and have you tried flipping the horns around the other way. (although this may be difficult depending on obstructions around the horn, I've no idea about the bottom of the VN dash..)

In regards to the time alignment some time alignment can actually compensate for intensity differences and vice versa. (in a limited way though)..

I have image dynamic CD1 minihorns

I cant flip them over i guess, as the minhorns are pretty much symetrical.

Cars a VT, not much room at all, no one thought minihorns could fit in a VT

[Mr_Bob]

in regards to your time alignment anomaly have you checked relative phase of the horns?

sounds to me like your legs are blocking the top end creating a soundstage shift.
ambients will help rectify this, but it's a fundamental problem with your horn locations by the sounds of things.

Phase wont be an issue at say 10,000 hz and above but lower definitly CHECK IT FIRST. tO MAKE SURE both diaphrams on the compression drivers are equal, may i suggest changing the drivers around. If it is still the same drivers are ok.I wouldn't suggest tilting BUT THEY SHOULD BE ON EQUAL ELEVATION PLANE. The phenominon you are describing usually happens when the curves of the under dash meet the horn are not the same. Thats whey mine were rebuilt.TIME ALIGNING SHOULD only be done from horn to mid to sub. NEVER LEFT TO RIGHT.

AS ALWAYS I SAY PLAY THE 7 SNEAR BEATS TO TEST THE SYSTEM

Wouldn't that be a track from an IASCA Disc? I know that track is great, but short of becoming a member of IASCA or have someone burn a copy for you, it would be "somewhat" difficult to get that CD in any major music store, right?

Cheers,
