New home, new system

Hello,

I plan to upgrade my current speakers (proac d18) with diy, my room is quite bad and speakers will be (very) close to front walls and will be quite close to side walls too.

I see diy as a way to get a better a speaker as a better price, I dont plan to tweak et get measurements, hence I need an available kit.

I plan to use some kind of totl driver (scan speak illmunator/revelator, seas nextel, purifi ...) with a fabric dome tweeter.

I was planning to build a small 3W, but considering the room and the simplicity of a 2W, I wonder if it is not a better solution right now. I could always build something bigger if I ever move in a bigger/better room.

Troels is an option and as a 3w exemple I considered Ekta mkii/SBA 7md and Purifi Fa/Illuminator 71 as 2W.

What do you think makes more sense 2w or 3w ? Any option/kit I should consider ?

Thanks for your help.

PS : Sound describing is always tricky but I am leaning more on the warm/non fatiguing side than cold/analytical
 
How do the D18s sound in this room? Have you tried stuffing the ports?

Corner placement is problematic. Are you planning to use subs?

I'd think a sealed design is the way to go.

I dunno if many 2-way kits are going to be miles different from the D18, so I'd tend to a 3-way with a woofer that can still do well sealed.

Look at @Pida's designs - he has a lot of experience with the driver ranges you're considering,

Considering the measurements of the D2 (standmount version, same drivers), I am no expert, but it seems there is real room for improvements, especially considering the boomy bass.

That looks like a good option, but there are not enough infomation on website to build one.

Anyway thanks for your help, really appreciated.

You could slightly restrict the proac ports with some grille cloth to tame the typical bass overshoot they have. A resistive port has a few benefits but it depends on how audible the restriction becomes. Increase in box stuffing can help alot too.

Seems like a good idea, but I don't think it is possible, port is facing the floor and you can't access through side holes ...

Stereophile's standard measurement method exaggerates bass, so some of that isn't real. From the review:
https://www.stereophile.com/content/proac-response-d-two-loudspeaker-measurements
"The apparent boost in the upper bass will be partly due to the nearfield measurement technique, but the D Two does appear to have a touch of the British-monitor bump in this region. Why didn't John Marks hear this? I suspect that the tweeter being a little hot balances this, so that the listener's ear latches on to the extremes at the treble and bass ends of the spectrum as being correct, and therefore perceives the broad trough in between as making the speaker sound a little laid-back. This is the classic "smile" balance that has been so popular over the years."

Yes, sorry I'm not clear myself if Pida's designs are public or one offs - you might email him or message him on here.

For other recommendations, what size is your room, how far do you listen from, what kind of budget did you set?

I was looking through A Heissmann's designs and found one that has been reviewed and is described as being suited for closed constructions as well as ported:

"=> Very adaptable, even in "complicated" rooms"

Doesn't use mega expensive drivers.

Room is very weirdly shaped, about 30 m², distance is 3m between backwall and listening position is 2,8m, speakers are 30 cm off wall now, so about 2,20 between speaker and listening position, speaker are 1,70 apart.

Budget for drivers/crossover is not really set, I would say about 2000€, I obvously don't mind if it is less, could be a little more if I find something really great.
 
Well, I have narrowed it down a 2way, easier to build and a big woofer will not fit in my room anyway.

Speakers will be quite close to walls and listening distance is short, less than 2,5m. I favor a textile tweeter.

Any kit ideas you could recommand ?

I thought of something based on 18wu or purifi.
