mikeymad Posted January 29, 2012 Report Posted January 29, 2012 Forming impressions I need to get my vinyl rig up and going again appove
Aura Posted January 30, 2012 Report Posted January 30, 2012 Hearing Marc's rig last night for about 30 minutes + buying some vinyl when we went to his local Austin record store = I want to get another speaker rig. Great midrange and controlled (and prominent!) low end. I'd say this was a great success .
swt61 Posted January 30, 2012 Report Posted January 30, 2012 Nicely done Sir! Those F4s might like some butcher blocks to sit on. Can't wait to listen!
luvdunhill Posted January 31, 2012 Author Report Posted January 31, 2012 The corner horns are very interesting. They remind me a lot of the first time I listened to Stax. They are unassuming and unimpressive in many ways. The low end of the piano is to die for, very nice. The thing I cannot make up my mind about is driving, low-end bass.... Am I a closet bass head? Who knows... I need more time for sure... I also have run out of current on my balanced isolation transformer I know that my CD player, preamp and mono blocks must draw more than 7.5A? That's crazy... How does one size these things, transformer VA rating divided my line voltage times losses? I am close I think as my box gets really really warm and strange buzzing and turn on thumps from hell. Hrumph...
n_maher Posted January 31, 2012 Report Posted January 31, 2012 For the pre and CD I'd take the idiots approach and look at the primary side fuses and see what their ratings are. That might be a half-decent estimate of start-up current draw but who knows about steady state. I don't think either's draw should vary all that much in use, should they? The mono's, bah, I wouldn't even hazard a guess but again they're probably fused... As to how to size the trafo, search me, if you neead a larger hole for a new trafo let me know. That I might be able to help with. From what I remember of Mark (voodoo) buildilng one of these there was a fair amout of give and take to the design in picking the right trafo that wouldn't give you way too much V-out but also wouldn't melt under load.
luvdunhill Posted January 31, 2012 Author Report Posted January 31, 2012 Thanks Nate! I am nearly positive the transformer is the issue. I plugged the amps into the wall and all is happy. I might try to find a bigger one as it seems to do a lot of good in my system.
swt61 Posted January 31, 2012 Report Posted January 31, 2012 As far as the driving, low end bass, that could be handled by an active subwoofer. Let's face it, even with horn loaded technology, a smallish driver can only move so much air. Why not let a 12" active sub kick in low to handle the slam and lowest octaves? I don't think it'd be that difficult to dial into your system. If you're looking for visceral impact, that's a good option in my book. Doesn't need to break the bank either... http://emotiva.com/xref_sub12.shtm
luvdunhill Posted February 1, 2012 Author Report Posted February 1, 2012 Got this from my bride. Perhaps now is the time to try and up the audio budget? "Do u mind if I put on music on using your cd player and amplifier?"
NekoAudio Posted February 2, 2012 Report Posted February 2, 2012 luvdunhill, what sort of monoblocks are those?
luvdunhill Posted February 2, 2012 Author Report Posted February 2, 2012 Wes, They are two of these per channel (balanced bridge), more or less (ah the hubris...)
NekoAudio Posted February 3, 2012 Report Posted February 3, 2012 Nice. They look purty on the outside too.
swt61 Posted February 3, 2012 Report Posted February 3, 2012 They look even better in person. They sound better in person too.
luvdunhill Posted February 15, 2012 Author Report Posted February 15, 2012 So, here's an interesting anecdote. These speakers* (kinda, mine use the newer DX4, but no need to split hairs) were supposedly BBC reference design for a time and were replaced by the Quad ESL57. Whether this is true or not, I could very well see the similarities. They are really growing on me. I'm talking with a wood vendor to really dress these up. Interestingly, they have a solid piece of Wenge that would span the front of these (didn't ask the price). I also got the new phase plugs in the mail. Anyone want to turn some wood for me? It would be cool to copy them in some exotic.
swt61 Posted February 16, 2012 Report Posted February 16, 2012 I'll need to see them, to be able to evaluate whether I have the right lathe chuck to reproduce them.
luvdunhill Posted February 22, 2012 Author Report Posted February 22, 2012 They look like this. The back side is the same as the door knob versions (some half-metric size, no idea where to get that... It seems like a M3.5?)
swt61 Posted February 22, 2012 Report Posted February 22, 2012 I don't have the right chuck to hold something like that. We may need to sweet talk one of the guys around here with a Nova chuck, or Kevin.
n_maher Posted February 22, 2012 Report Posted February 22, 2012 Steve, I could loan you a Nova for a while...
