saishibu- Buddy, You got it wrong.
The JBL BassPRo12 is not a bass tube. It is a subwoofer with an inbuilt amplifier. I think there are no Basstubes with inbuilt amp. Correct me if i am wrong.
Dont know the cost of BassPro12. Sorry.
Here is the link for BassPro12 and other products- JBL India, JBL Speakers, JBL Car Audio, JBL Amplifiers Delhi
And, The Subwoofer is a small box giving a punchy bass(Boom boom boom!). They are available in 12" and 15", 8" and 10" ranges and even more. They are available for Rs.4-8k.
The Basstube is a long cylindrical tube with Sub like structure on one side. It gives better and deep bass (Booom Bhooom Booooooom!). They are bit on a higher price than a sub.
Sub or basstube, Both require an amp. A 2ch amp can be connected to any 2 speakers or a single Sub only. 4 Ch amp can be connected to any two speakers + Sub. A mono amplifier is specially designed for a subwoofer and boosts the performance of sub to highest levels! Mono amps cost around 8k.
(Sorry : had no other thing to explain the sound!)
Dont know if pioneer has basstubes. But it has Xplod Subwoofer. Check on thier site.
People prefer Subwoofers over bass tubes as Subwoofers require less space and Bass tube eat up all the space of the boot. In a small car like nano
, A basstube will leave no space in the boot. If you are ready to compromise on Boot space, GO FOR BASSTUBES.
If the painter says the JBL Basstube isRs.5200, Then an amp would definitely be Rs.5000. Are you ready to give 10k? Instead you can go for a 8-10 inch subwoofer (Hardly 4000) and get an enclosure made (It is necessary) of 500 Rs. and get a 2Ch amp (Rs.5000). What say? Gurus, If any information above is wrong, Please correct!
