Peerless XLS 12" designs

[Sheld]

I've hunted around and figured out that a good Peerless 12" will work well in a small box so am happy to buy one. I'm not good at modelling subs so will end up copying someone’s design or going off the recommendations of forum members. The problem is I don't know which Peerless 12" to get and whether or not to get a PR as well.

My only real determining factors are size (2 - 2.5ft) and good for Home Theatre (low frequency). I have small main speakers so want good reproduction up to 150Hz too. This is my first sub project so don't want it to be ported.

Is it best (safest) to stick with the 830500 and a 12" PR?
I can't find any designs on this other than below which is very vague.

Does anyone have links to projects like this or similar.

Thanks

I'd go Linkwitz - they don't come much smarter at speaker design than him

You probably did not or missed it.
Here is a similar request with some replies.

I did not like any of the passive radiators I heard. I guess they were not set up well or had some other problems. However every bass reflex sub with the 830500 sounded very good. But the choice is left to you. Each type of box has its own plus and minus points. Look at the application link in the thread mentioned above.

Thanks ashok but I did search and found all the articles displayed by other forum members and also the d-s-t site itself but they are either for different applications (two PR's or two subs) or the d-s-t site is very vague.

Considering that the manufacturer recommends a configuration of 1x12" sub + 1x12" PR I would have expected to see more sites out there of people who have built this. I can't find any.

Anyone built this configuration?

A guy in the Melbourne Audio Club, Kendrick Pavey did, and I think there's an article by him on http://home.vicnet.net.au/~macinc/

Hi SSassen,

That seems interesting and just the thing I'm thinking of ....(I'm trying to find some project to use 2X XLS12" and a plate amp. in one box and without any PR's ) you have more here

but i can't understeand Dutch so if that is the configuration I'm looking for I would appreciate all the info i can get

There is something about it here but it's only a kit....

The thing is that there is some good sites/projects but they all use 10" XLS for that combo -like this

but i'f you are handy with WinISD you can use the sites to get a picture and ....

make a box bigger for 12" to fit....

I'm joking but i hope you understeand me

Your'e kinda cute, in a reddish way . .

Bac OT:
You're trying to find some project to use 2X XLS12" and a plate amp. in one box

Wired in series or parrallel ?

Why not have 2 separete boxes - spread the room modes, and spread the amp loads

[Mestinon]

I don't want to mess with Sheld's thread but i hope he will forgive me

Bottom point is :

two boxes are allways bigger then one and it is easier to make one then two....and more important if i have one plate amp i can't make two subs

second...I have 900€ for my sub and I need to spread the money smart and I'm looking do something what i can get throught some stores in this country...
I'm affraid that i don't have much choices...

*One store can order XLS 12"+PR for 400€
*Second one can order 2 x XLS 12" for 400€

so I'm thinking that it would be wise to take a second choice

or even give 510€ for 2xXXLS 12" designed for potr box use get myself out of this trouble putting big port in a small box with XLS as I don't want to use any PR or go with special active stuff ...

offcoures as there as no any 4Ohm XLS two would go in parallel but i'm not shure would Hypex DS 4.0 be enought power for that combo (btw, that's the only plate amp I can get here and it would be 450€ )

secend choice what i can get would be Behringer A500 for 250€ (I don't like the way of cooling of pro. models) but then I would need some active crossover


like you can see I'm in a mess of choices becouse I not following some project
