Thanx for posting this Sam,
this thread is something what i was looking for becoz as of now there is no ICE in my Ride.. heheheh..
I wish to have 2 pairs of it so i can make proper box and keep it in the back of my Gypsy and rock (@ Jesal:- do you remember your thoughts about the ICE setup in Gypsy

)and i think a sony 222 and a sony 300 will be enough for it. (its from my old car).

I dont know if u can call this D-I-Y!
But, my "pimped" ride is missing an entire ICE setup after it got repainted.
I have a Sony 502Z and a pio 4650 HU lying unused. Im either planning to mount those woofers in the Door panel with custom rings or make a pair of MDF enclosures for the woofers. And Im gonna add a pair of tweeters on the dash for the highs.
Logistics:One of My besshtt pals from Mumbai will pick them up and courier them to me.

a) Which Peerless
b) I assume this is 18mm. I hope it is well braced. 18mm MDF over 6.5 feet is rather flexible
c) I assume they are three quarter wave tranmission lines (not tubes) - why did you use this alignment?
d) No pics?
e) You can build 3 (rear and center). Keep center away from a CRT TV.

[quote=kkr2k2;382132] @navin and sam,
can four such 6.5'' subs in a custom enclosure produce better sound than one JBL bass tube in a verna. [quote]

Most 12" have lower Fs and more Xmax than most 6". so ginve that I would assume that in most applications the 12" would be the better bet when you want to produce 20-40Hz. Above 35Hz the 4 x 6" combo should be nicer.

Guys, given the antecedants of these drivers I am not sure of their use in a car. Only their impedance seems like they were built for the car.

Still since they are free no harm in trying. Mate a bunch of these to an equal number of those TS20 tweeters and you'll wake the dead - BOOM-TIZZ-BOOM-TIZZ.

Sam Kapasi · 28th February 2007, 16:12

Like Navin says, I'm not too sure about in car use. Guys, I was hoping for a little more than, "I want to fit them in my car"

Anyways, they wont sound good in a car just by putting them in
Not unless they're in an enclosure, with tweeters and a 2 way crossover.

Pdev, you will need tweeters mate.

Moral-sure, i must have missed your post.

This is mushrooming lol. I'm getting confused.

Then,im gonna add a pair of good 4" co-axials in the dash.

navin · 28th February 2007, 16:17

LBM, I have not asked for a pair.

I do love DIY and will help anyone trying to. but guys lDIY does not always work out cheaper. However DIY is a great learning experience so if you treat as a learning expereince go ahead.

Making a decnt pair of 6" 2way speakers using these woofer would still cost about 8-10K.

its all like greek and latin to me.
how should i let you know what i want...

, i like the bass to be hard not soft.(not sure, hard and soft is a right description).

how about this, i have a pio DEH7450MP, HU with rear pio 300W co-axials. and 100W in the front. I like the bass produced by the rear ones with max loud setting in the HU.

so where does this hard bass sound lie in??? in between 20 and 40 Hz or 35Hz.

navin · 28th February 2007, 16:19

Sorry to rain on your parade but....

Assume the woofers are free...

You need 2 tweeters. a pair of XOs and a pair of boxes.

2 dome tweeters from say Philips or Peerless would run you about 5-6K atleast.

A pair of traditional XOs will cost you about 1K per pair if you use an air core inductor for atleast the woofer (series) and CTR poly caps.

Boxes would run you anything from 1.5K - 2K each if made from 21mm MDF and braced, damped veneered and polished.

So expect to spend about 10K for a pair of speakers using this woofer. Mordant Short, Wharfdale, Epos and DALI (of the top of my head) offer similar speakers.

Now it is not for me to run counter to the DIY trend but I DIY not to save money but to (a) learn and (b) to build stuff you cant buy for love or money. If I add up all I have spent on DIY over the years I could easily have bought a rather nice system off the shelf. So do this to learn and treat all else as bonus.

So how do MS, DALI and co sell speakers at this price (hey I think even B&W has a 5-6" 2 way for this price range)?

a) they get teh woofers and tweeters for pennies.
b) they build a lot in China in high volumes
c) they use a paper "laminate" and not veneer, in fact the wood is pre-laminated and cut using CNC machines
d) they dont use air core indutors or poly caps
e) they make volumes!

put these in your doors and the 4" in your dash feed the 4" via a bass blocker and you might have a nice system. dont know if the 6" will boom in your doors though.

Sam Kapasi · 28th February 2007, 16:22

Navin, you would not get a decent pair of bookshelf speakers for less than 15-20K

Edit: This thread is going maad.
