I'm still confused on the need here. WTF is the requirement?

Hi Keith.... Yogibear more or less answered what I'm looking for. The 12" driver i currently have... needs 110L enclosure to give a flat responce !!! That's 14"x16"x40" Ridiculous right ???1. Define a "pro" driver! Why "pro"?
2. High SPL? High? Do I need to say more?
3. Should cover "highs". Can you define a freq spectrum for this?
4. Good vocals? Good? Do I need to say more?
5. Should go down to 80 Hz. Easily doable with many drivers.
6. And "in a smallest enclosure possible". Given the right driver, doable! Who determines what "smallest" means? Small in height? Width? Depth?
You are open ended about a lot. Opinions will be never ending given your open ended requirements. Close the loop or else this is going nowhere. Not good for anyone and that includes you.

Hey Keith... I'm in regular touch with Iwai...Naveen, have you tried contacting the iWai guys with your requirement? They're helpful and they make very nice drivers.
I will take your suggestions Yogibear....I do appreciate your DIY enthu and queries. Thats the way to go for a serious DIYer but don't jump on driver purchases so soon. Experimenting is good but I would personally refrain from buying drivers just for the sake of trying them until unless they are really cheap. Further for HT need, don't look for any larger than 8".
Well.....as you said Keith...without building a reasonably ok speakers, I can not look at upgrading any other component in my chain....IMO:
Your speakers WILL make/break your system so concentrate on those first and get them right.
Your room WILL break the sound.
How will you look at cables/placement etc. if you don't concentrate on your speakers first? You cannot put the cart before the horse.
Thank you so much for the explanation and the link Kannan.... I m sure I'm moving towards my targetThe SPL is an important parameter to choose, but should not be seen in isolation. You have to weigh in the power handling, cone area, excursion and other factors.
With the Dayton RS100, the f3 (3db drop in lowest usable frequency) will be around 70 hz in a vented enclosure of 3 liters.
With some filling or going upto around 3.7 liters, you can get f3 between 60-65hz without any ringing or bloat.
The roll off will start at around 11 khz, and is very smooth.
Ofcourse you room size is also important. It would perform very well with an active sub in a room of floor area upto around 180 sq.ft, and listening distance up to 10 feet.
In my car, I have it is a 1.25 liter enclosure in the dashborad and have crossed it from 315hz at 12 db slope. Cannot go more on the volume due to space constrains, so have a midbass in the doors to compliment it for the lows
Do read this............

If your placement is on the wall then a shallow enclosure will be able to utilise the wall as a 'baffle' for extending the lows.
No matter what driver you choose, one thing is for sure, a driver against the wall will need Eq. And once Eq is done by measurement the low Xmax of the driver will be compensated by 'boundary enhancement'.

Thanks a lo Aniket !!!!Hello Naveen,
You can try Capital Radio 10" pro woofer, which I have used in a cinema application, behind the screen speakers. they performed well paired with eminence compression drivers. I might have the crossover schematic also. spec sheets are attached.
good thing is, they are 2400 INR each.
Thanks a lo Aniket !!!!
Specs looks nice. Would like to try them once .... But could not find where they are available in the market. Will search further ....
