Hi everyone .Some while ago I had a pair of alpair 10M in a vented pair of 15 liters and because I've loved it so much I built another pair of speakers with 2 pcs each (30 Liters) . Even better , stronger powerful , just perfect . Almost perfect , because I thought my self " what if I make a new pair with 4 drivers for each speaker ? " Honestly I was inspired from Eikona but I believe it's risky to just copy that plan because it might not match ; so I guess , classic vented will be enough .Can someone help me with winISD ? I'm not lazy but I'm just not very good with it .I'm open to suggestions . Thank you
4 x 6" flat line array ?
You will lose a lot of high frequencies.
There is a thread i started of a 4 x 5" flat line array.

I just read it shortly . So you think I should't go for it ? The difference from one driver per box , to two drivers per box was really positive .I didn't expect to see a negative on with 4 drivers .

People do it.
I would not.
But go and make it.
You will need to boost highs.
Remember, you are asking for opinions.

Hi,
May I ask why there will be a loss in high frequencies? Is it because of cancellation?
It is certainly doable.
Maybe something like this?

This for the P11, so not suited to the A10.3.
The drivers have been arranged EPI Tower style to give an omnidirectional response and avoid combing.
2 on the front and the other 2 on the sides would work as well, if you are happy with the combing in a pair.
Otherwise some method to relieve some of the driver sof their top end would be nescessary.
Would give more bottom (not lower) and be 5 dB more efficient (sensitivity depends on how they are wired.
This shows the alternates to straigy parallel, series, or series/parallel.

You may find it works for you, but you will likely need to play with a filter.
Toole has shown that combing looks worse than it sounds, but it is quite individual.
The further you are from the speakers the less the issue is.
I would go with something that has max 2 drivers firing forward running FR, and some find only 1 is best.
Do you have an amplifier happy with either really low impedance (2Ω) or high (32Ω)?

I found 2 x 4" (5" frames) very difficult to stay in vertical sweet spot.
Slump a little and you lose s's and t's.

This discussion is relevant here: 4 x 5” FR� flat array ?
The W14s are spaced in the subject about the same as you could get A10.3, so except for the differences up top, much applies.
