Hi Guys

Was having a browse at a new set of splits today mainly the boston pros and a topic of discussion came up with the sales guy I was talking with. To be honust I found the bostons tweeter a little bright but he said when they install these of the z6's into cars they actually mount the tweeter directly over the woofer in coax style i.e both mid and tweeter in the one hole in the door. Looking at the boston catalogue the picture shows the z6's setup this way.

I have the ability to do this with my mbquarts I currently have but never tried it as I thought that defeated the purpose of buying splits in the first place and imaging may be hurt.

so what I'm asking is does anyone here mount there splits in the coax arrangement. If so why? and any noted gains or losses from moutning them in this config?

thanks in advance

my left & right speakers are boston pro 6.5's, and i have them mounted as coaxials using the provided 'axis-mount' kit.

i do this simply because i get better coherence between the mid and tweet, there is zero seperation and it makes setting up the imaging a bit easier as there are less variables.

however, these speakers are mounted in heavily angled door pods which helps when using a coax arrangement as you need to get those tweets on-axis in addition to the midrange. note im running a 5.1 setup so its a bit different to a regular stereo, but still the coaxes in the doors work well even in stereo mode.

the rationale behind 'splits' is that most people are unable to mount the woofer on-axis (ie: properly angled towards your ears), but due to the physically small size of tweeters, it IS possible to mount these on-axis without much trouble.

coax's are usually limited by the inability to angle the tweeter optimally (of course some coax's have tweeters on a swivel). this makes them relatively inferior to splits.

however, IF you can properly angle the woofer and tweeter, like T-bro, then you have the advantage of both proper on-axis imaging, plus a far more coherent 'point source', where all the music is coming from a single spot each side. coz even a little distance between woofer and tweet (say 20cm) will produce a 'separation' effect where you can localise music from 2 different spots each side (not ideal).

usually not a major issue, but potentially so.
