Well all I can say is that a large percentage of mastering engineers still use them, they were used to remaster the Beatles at Abbey, they are considered to be one of the greats used especially to mix and master the most demanding classical music and in fact they were Keeles reference until he wanted to sell his own speakers. In all honesty I have used owned and heard it all l. The 801s are a reliable reference to mix and master on. I thiink what bugs me the most is the flat 2 dimensional sound of direct radiators, the subtle compression. Actually I am done wih direct radiators I KNOW 100% now that they are and always will be inferior. As soon as a horn loaded ref speaker that is accepted by the masses to see in a mastering house is here these direct radiating bastards are out the door. !��������
Keele was critical of B&W's for a long time, since Audio Magazine was still around at least.
If the B&W's are so reliable, I wonder what happened with LotR's, or if they used something else. Seriously I am curious.

Yet he owns them and used them as his reference for a very long time probably still has them (hey DK are you around please comment oh Lord of the Speakers) I certainly say they are accurate as far as fr and a lot of other relevant specs are concerned. They do the job, and as I say you are very likely to have listened to thousands of tunes mastered on them. Yet verily they sucketh mightely to listen to after good horns are heard.
Back to topic. It seems if I close these cabs up I could use a lot of different 15"s in there given the limited bandwidth I need huh? Thinking ev 15l or 15x perhaps. Same goes for drivers on those nice ev design "stolen" cd horns?

Let us not forget WAF. Actually, acceptance factor at all. 🙂 Nothing says "crazy speaker guy" more than some one who has a pair of Klipshorns in a 5' x 5' closet he spends all day in. 🙂
The one's who pour the foundations of their basement to make a concrete, horn loaded subwoofer of course are right up there with the guy who attached balloons to his lawn chair to fly.

I am working towards an all horn monitor that is of a reasonable size. This one is a 16in cube. Is that too big? What kind of specs are you looking for with Max SPL, bass extension, HD, etc ? The Trynergy has very low distortion and is also quasi transient perfect and good flat phase response. I am not there yet but looking for criteria that a pro mastering engineer would be looking for.

Neat!
For my own tastes though, I'd say there's a bit of a midrange hump. The tweeter ends in a good place, but i'd consider lowering the resposne between 300Hz and 3kHz just a couple of db.
Also can you post the individual drivers with individual phase response? And /or with tweeter inverted? I'd love to see that. You are cheating by doing this all in DSP though. 🙂 🙂 🙂
Thanks,
Erik

that makes a living playing mixing mastering music. For that matter I think it's time for men to put the damn car back in the garage and take back a portion of his own house. Men also, do not get pregnant, nor does a 230lb man get his butt kicked by a 130 lb woman.
Here is the info you requested. Note that a Harsch Xo does not have a deep null when tweeter is flipped in polarity. It's asymmetric 4th and 2nd order filters with a large time delay equal to half a period at XO frequency.
Tweeter inverted is light blue:
Tweeter phase:
Woofer phase:
Combined phase:
I think I already have a slight tilt of about -3dB from bass to HF - you like more than that? Easy with miniDSP.
I did a Harsch XO design in passives with another speaker - kind of complex because drivers had so many peaks to deal with. Had I chosen a smoother woofer to start with the XO would be simpler. More info here;

I'm going to have to read up on Harsh then. 🙂
Originally I thought the issue was the tilt of the tweeter FR, but it's not. The tilt and starting/ending location of the tweeter is fine. Rather, there's a subtle hump from around 300Hz to 3kHz.
I would leave the tweeter alone and see what it looks like and sounds like by reducing that range about 2db in the center of that.

That low end will be done with two dl15ws per side in a tl606 cab.
I am thinking there are better 80 to 800 15s than the Eminence that is probably a k33 clone. Altec or Jbl or EV 15l?

I have some Altec 421s that might be ideal if I can fit them in there as they are actually 16" but made for an enhanced high end lead guitar etc?
For the record, I don't really think doing everything in miniDSP is cheating. 🙂 I was just trolling. 🙂

Off topic again but I will reiterate that not using dsp at this time might, just might not be the smartest thing to do anymore. $12 hundred watt per channel chip amps working at 99% effiency is pretty compelling. I also wonder uf some sort of speaker level programable digital xover might be what is possible. I have no idea how this would work but it seems very logical. CRAP blew another patent.
The on the fly programmable XO and EQ curves is standard practice for DSP based active monitors from many companies like Genelec and JBL. Less so XO, but EQ certainly. I play with different XO's on my monitors all the time. LR2 vs LR4 vs Harsch vs BW1, etc. they all sound different and allow different uses.
I'm not sure what $12 hundred watt per channel means, but I am really tempted by the Hypex plate amps with built in DSP equalizers. The thought of sitting at my PC, adjusting and measuring the crossovers instantly is damn compelling. 🙂 I'm thinking of getting one for my center channel build. Would eliminate the need for a power amp for it and maybe if I do the surrounds the same thing. Then Skywalker ranch can come and use MY listening room for a fee... muahahahahaha. And Dolby, whose building is next door to my apartment, can kiss it.

Maybe he means this?

And indeed, paired with a miniDSP I can sit from my PC and tweak XO's and EQ's to my hearts' content. I am using the above amps with a 24v hard disk drive smps and they sound great.
Yes I mean those. It is getting fairly obvious that the specs on those are working their way to being more than useable. Per on the fly: Yes I had some Focals that did that. However where I was going is who says digital processing must be done at line level? Could concievably be done at speaker level after amplification.
Those are $12 in stereo, so really $6 per 100w per channel 🙂
They are quite nice - no major issues that I have yet experienced, although to take them to 100w requires a larger power supply so I have not tested to to quoted power. But up to 30w, very clean and I would not be afraid to use for hifi.
The XO at line level allows small cheap DSP - when done at speaker line level, price goes up. Why would you want DSP done at speaker level?
