Heyas
I have one set of splits as front stage in my car atm (Vt 'dore)

The tweets are mounted in the stock tweeter positions, and woofers are in pods I made for the doors, angled up, with half of the bloody thing blocked by the crapty mappocket. bloody honda designers :/

now I was thinking of installing another set of splits in the rear doors, and put the tweets from that set of splits in the front - Ive been thinking about mounting them on the top of the map pockets, still good clearance to the other side of the car, and easier too.
What are the potential problem with a setup like this?
I thought about maybe thered be too much treble up front, the alternative to this is mounting splits somewhere at the back, which would be great for the rear passengers, but it might ruin the front staging.

At the moment, I dont think the rear passengers can hear much treble at all, i sounds quite boomy at the back, so how should I go about solving this? Id rather not use coax systems, but if its the best way to go, then I might. Is there anyway of mounting a tweeter at the back and shielding it from the front? (since its directional you'd think it should be a bit easier?)

anyway, im all ears to any suggestions no matter how wack they are

different and interesting idea

it could work, but firt reaction is it sounds complicated, and so that makes things harder for you. if you use the rear tweeters (upfront) as ambients, you can use the fader control to set their level, helping to raise stage height and expand ambience. this would leave midrange and midbass for your rear passengers, but only at the level your tweeters were set at, which may not be loud enough. indeed, the lack of treble at the back could accentuate the old 'its too boomy back here' phenomenon.

personally, i dont give a rats what rear passengers think, i rarely have any and its not worth the money and time. but having the extra tweets upfront, attenuated with your fader control, may work well for you if done sensibly

Hey there, (first post back, just got the 'net on at home, been getting stuck into a Sound Engineering course hope I didn't miss too much )

Anyway, have you considered the option of having your REAR stage set up the same as your FRONT, IE splits in pod in the rear doors, angled, etc, etc?

Only instead of being a rear stage as such, it would be to your back seat passengers as the true front stage is to the front seat listeners!

I would imagine it would work quite well, if you managed to A: isolate the throw of the tweeters fron front to back (not too hard if you keep 'em low) and B: You may get phasing issues with the midbass drivers....this could be solved with some clever time alignment, but this= money pls really knowing what your doing..........

All up, I thik it could be done, but as T-Bro says, is it really worth it??

ideally, jay, thats what Id like to do
but no doubt there will be problems with the tweeter being heard at the front, thus ruinning the front stage. been thinking about making a "deflector" for the tweets, although im sure that will also sound **** .
problem with my car is that the door panels are too curvey, and it is next to impossible to make decent pods without having some setbacks (on my budget and time anyway)
if I was to mount the tweeters in the rear... umm I have NFI where I'd do it, possibly in the trim after cutting a piece out of it, but if its to be front stage, the door lock latch is in the way.

a problem i had with rear speakers down low in the doors (2-way coax's) was steering the soundstage downwards and rearwards whenever they were audible from the front. so in the end, i faded them right out, and currently have none.

for my new rears, i'll be mounting them on the parcel shelf up high, so stage height should not be affected.

as for the extra tweets up the front...what are you trying to achieve? more treble or better soundstaging?

It worked very nicely when i did it in my car, i just tested out tweet positions until i found the right one, had the midrange speakers extremely low in the far back on a side panel

it sounded really nice although i only did it because i had a spare amp/set of speakers laying around, in my new system i also have no rear fill.

i discard all theory when it comes to speaker placement as quite often the most odd positions sound the best

well thats really why I dont want to go with coax
thinking about possibly mounting tweeters behind headrests, but chances are that will sound crap too
I was thinking of putting the tweeters from the rear to the front so that it doesnt ruin the soundstage of the front while you can hear it from the back, but so far that doesnt seem like its going to work either

Well ive got 6.5 inch boston pro splits for my front stage - powered by the kicker zr240.

My rear stage comprises of new boston acoustic RALLY splits which are mounted in the standard speaker locations on either side of the parcel shelf (so they face up, as if they were mounted in the parcel shelf) and the tweeters are mounted next to the woofer with those angled tweeter brackets. Ive angled the tweets precisly so that they hit both the rear passangers and the front passangers. The rear stage is powered by the new boston acoustic's gt-22 amp..I think puts out 2*110 wrms...> 500wrms bridged at 1 or 2 ohms. i dunno.

Anyway for me it sounds unreal, on my deck of-course i fade the rear down. But personally i actually like hearing the slite sound of trebale(music) from the rear. LIKEWISE it comes down to personnel taste i think.

Good luck,
