Bass Reflex plan recommendations for philips full range drivers.

[biyer]

Hi,

I am planning to construct a bass reflex enclosure for a pair of philips 8" full range driver. Its the same driver which Jaudere is using in his open baffle box. No t/s parameters available.
After a failed attempt at measuring its t/s parameters I am planning to take a risk and build an enclosure based on classic designs provided for other drivers

Philips fullrange

ALTEC PLANS

Should I just pick up any of the above plans or go the open baffle way?
My fearwith open baffle is that I may loose too much bass.
BTW I am thinking of using these speakers for listening to old hindi songs.

Hai Cranky,

I have seen in chennai Ritchie street that the Philips 8 inch Full range driver (Hi-Q Model) is actually made by Boston Acoustics, as per the dealer the Philips Brand for Speakers were taken over by Boston recently . The fit and finish of the speaker were good. Also the T/S Parameters were printed on the Carton, which I think no other Indian Brand does. How do you rate this speakers SQ wise?. Do you have any enclosure plans for this drivers. Pl let me know.

Thanks,

N Murali

hi Murali,

Can you do me a favour? if it is possible, please post the TS parameters of the driver. The drivers are indeed called Philips Hi-Q. to my surprise, there are 2 varieties of philips full rangers. one is called philips Hi-Q and has dual cone. the second is called philips full range driver and does not have dual cone.

I doubt that. The son of Late Mr. Moga (Bolton founder) is not interested in running Bolton. He is more into Real Estate. I will confirm it from Angshu who had access to Bolton factory.

Back to the driver, as Shri Cranky mentioned its best in a sealed box. Philips HiQ boxes were about 18 liters. From what I recall dimensions were 12x9x15 or thereabout.

Back in the days it was a favourite driver costing about Rs. 150 ea. I recently bought a pair (4 Ohms) to install in my vehicle.

Considering your musical preference, this could be an excellent choice. Best of luck !!

A thousand apologies only, Sir.

I can explain as below :

1. You stagger home at 1AM after a Saturday night out, in a reasonably cheerful condition
2. The bifocals are not on your nose.
3. Your laptop is smaller than it should be for your age, particularly when you are in a fuddled state.
4. An irritable wife in background #$%!! You have to now surf also! @#$

But on a positive, you will note that I still remembered the enclosure volume

Hey reviving a old thread
I am told on lamington road that Philips 12 Inch Fullange drivers are available @ Rs 950 a Piece..
Now
1) Is philips makes any 12 Inch drivers
2) Are they useful?
3) Any no brain easy DIY design is based on it? I mean I can ask carpenter to make a boy - In that 12 inch hole and voila! my speaker is ready!

Or I am asking too much!

1)I have heard the 12" . i think they are woofers and not full rangers(on the cardboard box, they call it a "Speaker", that's all! the dealer was trying to sell it to me as full range (he said"don't you believe in what is written on speakers?"then i listened to the sound and made him listen to the sound. they are not full rangers.the price is right (same in pune where i bought my drivers). low powered: 70W RMS

2) they can be useful in 3 way design. but again they come in plain brown cardboard box. nothing written on them, T/S is a big ask! so i don't know how to construct the box.

3) i am using "no brain" easy DIY design. : called open baffle. use Philips hi-Q full rangers with philips tweeters. I am very happy with them . to get a good bass on open baffle , you need larger drivers. i am using 15" drivers for bass.


I enquired about why they come in such a hopeless packing with no information, i was told that they are produced as replacement drivers for philips speakers which have broken down. so the box/crossover , everything is ready and no one needs T/S parameters. when you don't know about T/S parameters, "no box" is the easiest box to built as long as you lucky enough to have high Qts (>0.7 at least)

Dear Murali,

I am a fan of the Philips Hi-Q speakers and have been using them for the last 20 years or so. Recently one of the pair has gone dead and I am looking for a replacement.

I would heartily recommend that you use these speakers as front L-R speakers.

regards.

you got to be kidding.....

I used this speakers in 1972 through 2000, and they still make and sell these?

This must be a record of some sort for longest production of a speaker model/type.

I agree with chikoo 20 years ... it should be a record of some sort

38 year old Hi-Q with dual cones here They're about to get their 38 year old aluminium 26 gauge cables replaced with 18gauge tinned copper ones

Update:
Found it here

[greenhorn]

DIYaudiocart seems to have measured the TS parameters of the speakers
Boston Acoustics - HQ48413P - 8" Hi-Q Fullrange Driver - 4 Ohms - Pair
(they also seem to have measured this for all the models)
