I want to make 3 way speakers with peerles SLS12, so what kind of speaker you sugest-bass reflex or compresion-sealed?
Totally depends on your needs and your room..
Generally:
A BR enclosure is deeper reaching and louder, but larger.
A closed speaker produces thighter bass and is smaller.

Sls12 is not good speaker to 3way system.
This speaker is good to a subwoofer in home cinema.
Visaton w300s is better to 3way.

I am currently working on a 3 way with your Peerless SLS 12 inch 830669 woofer. The driver is suited to a sealed enclosure with its x max being longer than woofers optimized for vented enclosures. Its EBP is at about 55, which again, puts it into the category of being better suited for a sealed enclosure....My cabinet size is 4 cubic feet and could possibly even be a bit larger, however I will be experimenting with damping material, by ear..........Maxi, could you expand on your statement as to why this particular driver is not good for a 3 way system?..........Respectfully......Omni
I had made an 3 ways speaker with the sls315 in 110L bass reflex enclosure...
Bass very loud but clean, I have to separate me because of the obstruction of those 😀 ...now i have regret

An externally hosted image should be here but it was not working when we last tested it.

Hi,
I se no reason why this SLS12 should not work well in a 3-way speaker. Qts suitable for closed box and high Qm eg little mechanical damping, something I consider important for good low level dynamics. Good flat reponse with no major brakeups before 1.5kHz so crossover freq up to 500Hz should be no problem exept for some beaming due to the 12" size.
But I could be wrong as I have not audition the unit, just drawn my conclusions from spec.

I tried something with the SLS-10 in a 45l sealed cabinet, but it had too low output and also didn't play as deep as I wanted (f3 f10 / 60 40Hz).
The SLS-12 is very much the same, maybe has (little) more output and more depth (in a bigger volume), could work for you!

70l is right on what Peerless has suggested under application notes for SLS12:

Should work fine with good transient behaviour. But as can be seen in graphs do not expect so much below 30-40Hz, however room gain will assist well as falling slope is 12dB/octave due to closed box.
How will rest of speaker be configured?

I listen rock and hard rock,so I will be hapy with 35Hz.
The rest of speaker is

What you think about it?
Hi,
I think you will have a good sounding box if you don't demand super low frequencies.
What will Q be in the small midwoofer box?
Just my opinion but I suggest a slightly higher crossover than 135 Hz maybe up to 200-300Hz if all speakers are close in same box pointing in one direction. Your 12" will have better kick and at the same time release strain from mid driver. Another benefit is smaller coils if you are planning a passive crossover. This is of course a matter of testing, somewhere you will find the right crossover.

Q stands for the compliance of the air inside the box, small Qc tends to sound thin and large QC tends to sound bass heavy or as many people call it "slow"...
Q is the "quality factor" of a resonance. High Q good resonance in small passband, low Q less good resonance in a wider passband.
Every resonant system is going to have a Q-value(s).
Some fundamentals about Q in general here:
http://en.wikipedia.org/wiki/Q_factor
In your small box for mid woofer you are creating a system in its own speaker-box that are going to have its own Q (Qtc) value, knowing this (easily found by any online calculator) one can predict frequency response and impulse behaviour from that system. The lower you cross over to main voofer the more important it is to know this value.
Hi,
From given parameters I would cross around 300Hz and 8l box is fine. Suspect that this is a dedicated large midrange driver.
