Hi nick,
Thanks for chiming in, I read somewhere that you have experience with both Rel and Rythmik/GR combo. I m indeed using ONE humble Rel Strata 3, on an extended loan from friend, i.e. free.
Thus far, I could dial it in fairly seemless with ESL 57. It is not hard work. Quite un-expectedly, it is far too hard to blend in with Tannoy 15" Gold, in Rect. York Enclosures. Finally, I sort out the hum issue that prevents me from using the high input. Once I got high input to work, it blends fine with Tannoy.
Recently, acquired the ESL 2905, it does not work as easy with 57 on low level input. High level input hum issue returned and I was hoping high level input could get me blended in with the 2905.
Here is some of my questions,
1. I understand you like the Rythymik solution better than Rel. May I have some ideas on the "why" side?
2. I am talking about 2 channel application, no HT requirement at the moment. Do you use one or two subs?
3. Rel could be have from used market for some silly amount of small money, say a Strata 2 for less than 200 US$, do you think it still justify the path of DIY for the performance gain? Make no mistake, I do have lot of respect on the OB solution mentioned here, in fact, I am quite interested. However, money for sure is an issue, but the TIME for the DIY part is another huge issue, cost of making mistake too.
Look forward to some more interaction.
The "servo" system monitors driver position using an extra voice coil on the woofer and a special card in the amplifier. Changes are then applied in the amplifiers feedback loop so the driver position always matches the input signal of the amplifier. Simple, dependable, fast and brilliant solution for really tight, deep tunefull bass up to 200hz.
