Digital xover makes sense only if you don't listen to analog sources. But even in the case that you listen to digital only.... I'm not sure about most DSP machines. They can do whatever you like with a couple of clicks, but all those I tried sounded like cheap dacs, in most cases they need...

I have been playing active for a long time, and I will never go back. The DBX 223 and DBX 234 are wonderful machines for entering into active territory. I've been using the 234 for years and it's pretty good even in high quality systems. See what Troels Gravensen (a well respected loudspeaker...

thanks a lot.... The 870 circuit seems so simple... I wonder if it would make sense to take one of those old cheap amp and put some serious components

I know there are a lot of enthusiasts on this forum with a great culture of vintage equipment from the golden age of British hifi. I listened to the Rotel RB 870 BX in a reference system, just for fun. That amplifier probably costed less than the three spikes under the preamp power supply! To...

Looking for a Counterpoint SA 5.1 tube preamp.

Hello Dears the Phono Cube of 47 Laboratory has received very good comments all around. I see there are two main DIY alternatives: RJM audio phonoclone and the Phono Stage by Audiosector (Peter Daniel). I got the RJM audio phonoclone and I think it sounds great... although I could only...

I've never owned a pair, but I auditioned the DBLs with active filters ten years ago, and I still remember them because I had one of the best audiophile Sundays of my life! We were a group of audiophile freaks invited by a rich audiophile buddy to eat, drink a listen to music all day long! The...

SOLD! tahnks Pierre

Dear All, I found several private messages. There are several people interested that all ask similar questions, so I try to answer here: 1. I normally travel a lot (Italy, Germany, UK, etc). I am often in London because I work with researchers University College London quite a lot. So if...

Dear forumers, about 10 month ago I bought a Buffalo II fully assembled and tested kit plus Placido PSU (without transformer). Unfortunately my work load increased a lot and I travel almost 4 hours every day until a find a new house near the new job place. I really don't have time to...

you are right there are caveats using your measurements with those estimated from datasheet, that's damn righ James. But at the moment I odn't have any other way of solving the problem so if you can sent the files I'll be very happy, Il send you a PM Thanks Pierre

OK if you can't pass me these measurements, thanks anyway Pierre

that's great, could you send me those data and a brief description of the conditions under which you took the measurements? Best Pierre

I have woofer and Midrange but I need to adpat one of my tweeters. I don't have a proper measurement system. So if you have raw measurement on the baffle (on axis, off axis whatever you have) it would be great. Any kind of data format (FRD style, CLIO style etc...) would be fine, I usually...

Dear All, I am going to build a PFM special but I don't want to buy a new pair of tweeters, I have so much stuffs here. Can somebody sent me measurements of the woofer and midrange? A txt file would be great. Best Wishes Pierre
