Thanks will look into it. And "how I do it"? What do you do buddy? That's an awful lot of drivers "burning in"!
George,
Please do look into the OB7 and X-Encore options. THey'll do HT and 2 channel audio extremely well.
Well if you notice what I had done there was hook up a CD player on repeat with some Percussion music (Andy Narell on Kettle drums etc..) and an old stereo amplifer (I think it was a Harman Kardon PM665) that put out about 100W rms. I hooked all the drivers in series parallel to get about 8 ohms per channel and let the system play for 3 days (8 hours a day).
Those were early days later I used a Function Generator with sine wave auto sweep and swept a tone from 50Hz to 100Hz over 2 hours and them amped it with a BGW 750 amplifer. It did the job faster. Be careful though you dont want to blow drivers up. A big amp meant I could burn in 32 woofers at a time.
Before you jump to conclusions, I was never part of the audio industry and never have been affiliated with any audio company or publication. I was just a DIYer and between 1976 to 1998 I built maybe 40 pairs of speakers each very different from the other. Everything from Philips 8065 woofers to ScanSpeak 18W8546 from Arphi 12" fullranges salvaged from the Orpheaus to JBL 2245/2235/2226 based 'bass bins' from UREI radial horns to London Decca ribbons.
The drivers you see in that photo are when ScanSpeak and Vifa were seperate companies in Videbaek. Pre DST, Pre Tympany. As you can see from the cellulose (tan coloured) drivers we still used 'bucking magnets' to sheild CRT TVs.

This picture was from 1997. I am, as my wife likes to call me, a fossil.
When I got married my wife threw out 2 Godrej cupabrds full of old drivers. Maybe about 100 drivers were given the the local "kabadi-walla". If Hifivision would have been around (we did not even have email though) I would have donated them to the young guns here. Some of the drivers were quite nice - I really miss the Aerogel cones from Audax, the 12cm doped paper cone that I had used to upgrade a DQ10 (along with the London Decca ribbon), the 34mm Audax dome, Vifa's 19mm domes used by Snell, oh the list was long. :-( even had a pair of the original MDT33s (pre 'butterfly' aka interchangable voice coils).
why its is so BIG ?
Danny would be the right person to answer that. BTW for 6 5" XBL woofers it is a fair volume.
