DBX Soundfield speakers. Anyone still running them?

[Todd MacDona]

I cannot tell if any of these posters did not get satisfactorily answered, and it is months old anyway, but anyone who needs dbx info (of any sort) can get in touch w me at drmoran at aol dot com . Including many manuals, which I wrote, w. engineering colleagues.

The dbx Soundfield line for sure worth owning (and repairing) comprises the One, 1A, Ten, 100, 1000, 1500, 150, 50, 2500, and 5000, and that is it. Everything else is DAK junk, the V and subs and all that. Some of those may be sonically acceptable, no idea, but they have nothing to do w dbx engineering and do not follow (as in having zero relation to) the Mark Davis (MIT PhD EE/psychoacoustics; AES Silver Fellow) computer-vetted empirically derived phased-array design work published in the AESJ, which achieves quite a good measure of offcenter centered image formation. And uniformly airy and spacious and detailed balanced sound when you sit still in the middle.

When you say "50", are you referring to the sf50?

IM SUR3 it is..One thing too make sure all the connections are correct as when I opened my sf 10's the previous owner must have reconnected them wrong.

Neg is positive and positive is neg..is the correct phase/

Once again a post that hasn't seen action for over a year and I see I did post to it. I got tired of seeing my SF10's being used as a place to put plants on and did some further research and discovered I could take the speaker output from my current AVR, attenuate the signal with a simple resistor circuit to make it line level and then feed it into my SF10 equaliser and then into another power amp. In fact rather than build the circuit (which didn't look that hard) I managed to find one of these units which were designed to perform this function and made by Carver no less

So now to refoam my SF10 subs and then the SF10's will have a new lease of life (only after about 20 years of non-use!)

I'd be fascinated to hear details about the Mark Davis (MIT PhD EE/pschoacoustics; AES silver fellow) computer-vetted empirically derived phased-array design work......)

I'm fascinated.

I don't recall hearing from you, and my email is public above, but did you get a copy of the AESJ paper on this?

cannot tell if this was a serious question, since

\\ One, 1A, Ten, 100, 1000, 1500, 150, 50, 2500, and 5000

in each instance you are to put SF in front, correct, as a prefix ....

trying to differentiate from the DAK stuff you still see out there, like on ebay

 

[david moran]

I play my SF 10's daily .. juicing them with mc2500 ..it's insane ..your favorite part of a song is coming, go ahead walk around, it's ok. The sweet spot follows you..
I have read , thanks to dr moran , all the fascinating literature on this apeaker and its big brother the 1A. How the 1A was a and b tested with other great speakers of it's era only to win the shootouts.

don't know if I responded to this or heard from you privately, but you are entirely welcome, and what you report is true, very striking

not a doctor, just my initials

remind me about said shootout, pls, or any other comparisons you know of or I reported

LOUDSPEAKERS SYSTEMS WITH OPTIMIZED WIDE LISTENING AND IMAGING....You emailed me the article a while back..The 1A bested many speakers of its era , its only downfall was its looks and its price for that era.
I moved on the OHM WALSH as I never could find the Super tweeter that I need for the side facing tweeters.

I don't think so, if you've got a copy, feel free to send it to jazzmans at gmail.

also, my wife LOATHED them, saying they looked like the trash receptacles outside nice office buildings. i agreed with her, but of course never let on that i did

Spoken like the true music loving audiofan that I want to be just like in all my audio experiments and restorations! Never divulge that she's right, especially about appearance.

Hi all - Just scored myself a pair of mint condition dbx Soundfield 10 (SF10) speakers with the controller forr $200. Totally love them! I searched everywgere on th einternet an dcannot find an owner manual.

Anyone have an origonal owner manual maybe you can scan & post here?

Funny this thread was resurrected. I just rebuilt a pair of DBX Soundfield 1As. Refoamed all four 10" woofers in each cabinet, and found a replacement dome tweeter for the "face toward other speaker" side of the speaker cabinet.

Honestly, I hadn't seen a pair of these since the 1980s, when the store I worked at carried them new.

Unfortunately, that store went out of business years ago. That's a shame, as with the packrat tendencies of the people who ran it, they MIGHT have still had manuals for all these old DBX speakers, if they were still around...

Regards,
Gordon.

DBX Soundfield 1As

i heard them in a store when they were brand new. i was young but i did think that they sounded incredible.
