F1/2/3 etc with Front Loaded hords and CD's

Brett · 26th January 2008, 10:28 PM

I did a search but almost everything came back being about BLH's. Has anyone used them in FLH's? If so, which one(s), what speakers and any other implementation details would be appreciated.

Also any comments on noise on very high efficiency systems would be nice.

I have some KHorns with a different MF/HF (probably 200 and 1k5 xovers @ LR24) section and would driver them from a digital source, through a DCX2496, 6 ch attenuator then the amps.
Initially thinking about an F1 for LF and a pair of F3 for Mf/HF. I have lots of Lovo's.

Room is small and quite solid, and I listen loud on occaision.

Comments? Thoughts? Experiences? Suggestions?

Brett,

Regarding noise on hi efficiency I guess it depends on the PSU implementation, though my speaker efficiency is only 94/95 dB/W I have no issues when doing a CLC filter on the PSU, choke is usually 10 to 15 mH though.

If this is of any help, my speakers are 104dB and I use a ZEN V4, which should be pretty similar to the F2/F3 - I have no audible noise at all from the ZEN V4, it is really dead quiet.

Thanks for the noise feedback Tony and Martin. Sounds like I have nothing to worry about i that regard then.

Now, if anyone would like to comment on defined O/P Z amplifiers and horn sonics, I'd appreciate that too.

My PSU is outboard and LCLC, and the regulator is RC filtered, but since I did not try a normal PSU I cannot confirm that this is really all necessary. I do remember though that someone on this forum did have noise problems with his ZEN V4, probably due to RF hash from the PSU. As always it depends on the implementation ...

Agree on that point.

But I think a Voltreg would be unnecessary if your chokes ar big enough say 5 or more mH. You would save on power and heat disipation.
