166 es-r BLH w/ t90a supertweeter

kazoo · 8th January 2007, 05:10 PM

Hi,
Has anyone tried this combination? I am looking into doing this combination but wanted some opinions first before I spend the money. Thanks for any input,
John

Yes. I bought the tweeters about 2 months ago. I have them capped in using a 0.68 uf cap. I feel the tweeters add air and sparkle without bringing attention to themselves; a worthwhile addition.

YMMV,

I'm in the process of intergrating a pair with my 166esr's. Smallest cap I have on hand is a 1.5uf which is definitely not small enough. Will be ordering smaller ones to try.

Are you using a fixed or variable value Lpad with your T90's? I have a cheap variable Lpad at the moment but wouldn't mind ording the parts for a good quality quality one when I order the smaller caps. Also have you tried any other sized caps with your t90's beside the 0.68uf's?

I would suggest using very decent ALPS pots for those nice Fostex tweeters. I use the Black Beauty's with a pair of Visaton TL16 supertweeter horn which are on top of a 4ft^3 ported enclosure loaded with the 8 inch Hemp cone with the whizzer extracted. This is a very fine sounding BR load, far, far better than we had imagined. The supertweeter adds air, and again doesnt draw attention to itself. I bet the Fostex might sound even better.

Thanks guys that is what I needed to push me over the little hump. I will report back once I get these on how they sound.

No L-PAD is used and one doesn’t seem to be necessary.

Right now I am using a cheap cap and Rat Shack 14 ga. speaker wire; I also have wiring harnesses made up for a 0.47 and 0.33 caps that I can switch in and out. I haven't decided which one I will eventually go with. After I have decided I will pick up couple of fancy dancy Fostex caps and wire from Madisound, although I am not sure if it will make a significant difference…..Any thoughts on this?

One more question on this. The L-pad is used to adjust the volume to match the driver, correct? Now for the caps, is there a spreadsheet that shows what value of cap will cross the tweeter at what frequency? So I guess a 0.47 would be 7000 Hz and .33 would be 8000 hz? Am I correct on this? I know the values will be different but is there something that shows the correlation. Pardon the question I am new to this.

Kazoo, Godzilla has a chart on his website that gives you roll off points for different value caps. There is alot more good info on his site also.

Thanks for the info. I have been on his site looking at BIBs but never noticed the other stuff.
