Indian equivalents of the following DIY items.

do you have the lambda running one channel and the DV12 the other or are both run mono?

the reason i got the dv12 is that it is quite flexible. i was hoping some day to build a servo sub and was hoping to use the second voice coil to provide the feedback instead of an accelerormeter.

anyway turns out that was more diffcult to do in practice so i then shorted the second voice coil to change the tuning of the sub.

turns out that the 10% change in F3 was not audible (measureable yes but not audible).

I use both the subs in mono, since my listening rooms aren't big enough to accomodate two boxes. One (currently the ACI) is mated to a two way using Raven R1 tweeters and Focal 5inch mids in an MTM box (the Aria R design by Joe D'Appolito), details of which can be seen on the Zalytron site, under "kits").

The other is the Lambda PR alignment which is mated to a two way using Scanspeak mids and tweeters (18W 8545) and D9300 ferrofluid silk domes. The second system has better bass extension, whereas the Raven tweeters on the first are outstanding, especially listening to female vocals. I rotate both systems for my use.

I plan to consider using my newest Lamda driver with my HT setup. I have a couple of PRs on order from the US, coming by sea mail! I have to decide what to do with them once they come here..

As I have said in the past, you're more than welcome if you happen to be in my vicinity to come by for an audition, and enjoy some asli single malt along with some good music! A CD that I picked up on this past visit to the US is Michael Crawford in Concert-great stuff. This is the guy who signs the male vocals in Phantom of the Opera.

u have 2 listening rooms! how did you get away with this.

i think the 8545+raven combo might be the best of both worlds. it would have require steep XO slopes.

besides the focal polyglass woofers might be too forward for the 9300.

my subs are 4 x DV12. 2 per box. sealed 130 liters. sats are 8546-9900 MTM.

this system is lying unused as it was too big to carry from my mom's apt where i lived when i was single. pics have been posted in the past so i wont waste bandwidth.

one day i hope to rework the MTM to a MT push push. the 4 woofers are best used a selaed box as any other box is way too big for the tiny apts we have in mumbai.

Hi Navin

I had a CD with a lot of backed upinfo on audio stuff which I seem to have misplaced. If you have it, could you please email me offlist the T/S parameters of the ACI DV 12 drivers(at gjo@dtsam.com)?

Many thanks!

Hi guys,

Any Idea where i can get good drivers in Bangalore?

Vivek :How about the Bolton woofers that you have bought?How is the performance .Also some inputs about where I can buy good woofers+tweeters. I plan to build a amp using stk 4192.

Suggestions are welcome!

Thanks in advance .

[navin]

corrson if you have the budget.

[Vivek]

You can try Vifa drivers from corrson (corrson.com) but they are terribly expensive. I am using a pair of Bolton 8 inch sub drivers for my sub project. They are pretty good.

By the way, my Vifa MTM project is almost ready. I am doing some listening tests. Some internal lining with polyfibre and bracing need to be done.

Vifa Drivers look good but there are a bit expensive. The drivers may be good but i am not sure if stk 4192 is worth this effort.

I will test the amp with some local woofers I have. I plan to use the amp to drive a sub woofer.If the amp works fine with local woofers then I plan to build a active filter using lm833. Finally if this also goes well then as a last step I will buy vifa drivers.

What do you guys think?Is the 4192 based amp worth all this effort??

Navin and Vivek please cooment.

[Vivek]

I used the STK 4171 amp kit sometime back. It sounded very good. The 4192 is probably good too. But don't use a 4 ohm speaker. My STK went up in smoke when I hooked it to the two Bolton (8 ohm) sub drivers in parallel.
