Någon som vet el har nån kuriosa om dessa? Bara rent nyfiken:)
Hittade lite kul här jag: http://www.diyaudio.com/forums/subwoofers/140741-servodrive-subwoofer.html
Saxat ur tråden: "Servodrives work great up to 80Hz+/- I'd never run them up to 100-120.
I wouldn't run them at 20Hz either 28Hz is their -3dB in groups of 4.
I would never describe them as sloppy sounding. Though I own the BT7's perhaps you owned the SDL-5's which were maintenance nightmares. I think perhaps you never had them combining well with the upper boxes.
My BT7s have no breakers, just an inductor resistor , and a filter for the fans bridge rectifier. The Servo also has a ballist resistor.
The big problem most people have with the BT7 (Mostly DJ's and people not in the know) is that running the BT7s amps into clipping caused too much HF energy to make it to the Motor, causing the belts to slip and overheat, and the motor to burn up.
I have 8 of the beasts, all of them are doing quite well for their age. I had one refurbished, and replaced the pads on 1 when I got them used.
I'm not sure why you think they can't handle enough power, remember that 4 of them is ~110dB efficient with just 1kW they put out 140dB 142dB at rated power, and 145dB peak.
How many subwoofers do you know that can put out 142dB @ 30Hz with only 1.6kW of power???
I love my BT7's

Finns mycket info på diyaudio. En del från TD själv.
Om det finns något arkiv från basslist finns det säkert hur mycket som helst där.
Kanske inget för hemmapularen då remmar och annat har lite oljud för sig. Kommer man dock upp lite i nivå samt lite avstånd är dom nog rätt awesome.
Å andra sidan finns det riktigt bra element idag som inte fanns då. |
Is that him?
That's the buffet table.
Well, how can we be sure unless we question it?
The D just stands for digital. The amp turns itself on and off between notes to save power.
Yeah! I love reading, and my head isn't even close to the shape of an egg!
It's more the shape of an apple, or maybe an orange, but a BIG orange, more like a grapefruit really...
