Indian equivalents of the following DIY items.

These are "new old stock" of some gray market JBL car audio drivers. A few months back when I wanted to start a project and had no place to start, I stopped into a car audio shop and these things were collecting dust on a back shelf. They looked versitile and they were inexpensive, so I gave them a try. Ajju (I think) also had some past experience with them. JBL is reputable company and I used to have many years ago a set of JBL stereo speakers (from the mid 70's) and I liked them.

The 6" ones look interesting also but are a little less hearty looking.

Just as an explaination, I entered this hobby with very basic knowledge, so I figured the FR / SD route was the fastest way to a finished product...

You know I keep saying that FR drivers rarely are FR... they are wide-range, perhaps much wider-range than non-FR ones, but that's all. I tend to believe a well-designed 2-way or 3-way speaker will beat almost any simple single-driver speaker, because FR is not really good enough to be used as FR.

I just found a Webpage describing a good single-driver speaker built using a Hi-Vi FR driver. See the comments towards the end, about massive distortion at low freq ranges. The designer says very clearly that this "FR" driver is best never used at really low frequencies... you need to put an xo and add a separate low-freq driver (eg. a woofer). Check out the Zaphaudio page which talks about this.

In earlier threads, I've mentioned the high-freq distortion with the very high-end Jordan FR driver. And so on...

The compromises just keep coming'

Hi,
Indeed there are compromises, but as an inspiration to the poetry of singledriver theory (which I still am ultimately attracted to), read the description on this link of Brentworth Sound Lab speakers. I am sure you can find flaws, but I love the approach BSL uses. They are obviously using some sort of tapered, or "valved", line

I have a friend in the states which has a set of these (the big ones). They are really very spectacular sounding and are excedingly efficient , although require some space to set them up properly.

Enjoy... and maybe become converted??

PS: Cadence/North Country Audio and their guru, Vladamir, are one of the most reliable and respected high end audio people around. They also produce some fine jazz recordings to boot. Their web site is a bit primative but they rely on reputation, service and quality.

Any one worked before with hi vi..?
Looks good, specs look good, and are comparitively cheaper (well on the web)..!!
Am very tempted to use them...may be a line array from some 3" units...!!

Hi Vi looks very interesting to me as there are some models that look like they are FR.

The 64K dollar question: is there an indian dealer that is willing to sell set by set??

Hi friends,
Has someone come across Blue Tac or some equivalent in India.I want to do the added mass Vas measurement and am looking for a suitable adhesive.
Thanks.

Considering the fact that Hi-Vi's model is completely web based, I sincerely doubt if any one would be ready to establish such a business...!. For some reason, we still are not mature enough to trade on the internet..!

Hi,
I do know some that have done some purchasing on the ebay.in with some success. Unfortnately there is still spotty selection of items, and of couse nothing much for us DIYers...but I do a search every so often.

Have you checked this thread, by the way?

Incidentally, I found BluTak in a stationery shop which sells some imported items. Look for any slightly trendy or westernised stationery shop, and you should be able to find BluTak... it's not that uncommon.

My first DIY speakers were some single-driver boxes with the Jordan JX92S. I am not sure there are FR drivers which are all that much better than the JX92S. I've heard six-foot Dunlavy floorstanders, and I feel that the JX92S, in its areas of strength, outshine those Dunlavies. In spite of this, I speak of the limitations of the FR approach. So you see, when I speak about FR limitations, I (for once!) speak from personal experience.

I guess you may have to travel along the same path, and live for a few months with drivers of the quality of the JX92S or better, before you see what I've seen. So, bon voyage, and don't forget to enjoy the scenery.
