2wq filters: what do you recommend?

Forget the X-2. In a word they "suck". DIY X-2 clones using a very high quality cap are vastly better. I like the DynamiCap. The only problem with the DynamiCap is that the .01uf cap is really more like .013uf. That can throw off the high pass point by quite a margin if you need, say two of them, for a .02uf filter for an 80Hz high pass into 100K.You now have a .026uf filter which will give you a high pass point of 61Hz into that same 100K. You might look into the Cardas caps or many others that sound very good.

The M5 is a great way to go but somewhat costly. The M5 is swithable for impedance like the WX-2 and uses much higher quality InfiniCaps which have a bias current placed on them via a 12v battery. I have never listened to them in my own system. Someone that I trust seems to think that this is the way to go if you want the very best sound with Vandy subs.

I have to say that the DynamiCap filter I am using is very hard to detect.

Very interesting. I have a pair of 2wq's and am currently using a pair of X-2's - 50khz. Could you explain to me how to make a better pair?? What caps would I need??

thanks,

Harry,

Get your hands on the best sounding .04uf caps(The caps need to be matched and as close to that exact value as they can for a 79.5Hz filter. You might want to measure the value of the X-2's you have and try to duplicate that value, it should be .04uf but all of the X-2's I have measured were way out of spec. This way is won't change the bass balance.) Get some M&F RCA's. Solder the caps on the hot side and a wire for ground. Sit back and prepare to enjoy a pair of filters that will put a grin on your face.

After word your X-2's will be for sale.
