Romy:Do you mean that if you begin with digital source, it does not matter whether you use a digital crossover or not since the "damage" has already been done?...
|
|
I think I figured it out. Capacitor polarity. I reversed the polarity (leads are black and red) and sound changed. Now it sounds closer to what I am looking for, with better transients. Not as good as the digital crossover in the transient department...

Watched youtube feeds and found my way back here. Interested to hear more about your priorities in the new build. Given the project is inspired by Dunlavy, I presume the build will be time aligned with first order crossover? If so, are you intendi...

With exception to the fact that I have no bass my new room did not give me a lot that I feel might be qualified as strange. I still do not know this room as good as I knew my old room but I will be there, it is a derivative of time. It is not tha...

OK, the Reps is so up-tilted that I cannot deal with it stock without a BH. So, back to the DX4, because I can't tie the ribbon on the Reps' tail. I have re-entered Crossover Hell. Programs and math up the wazoo. More, anon.Paul S...

Hello Romy,I didn't use John Hasquin's tapped horn design, I modeled my own in hornresp for my TAD woofer. I knew I would only need it up to ~55Hz so I was happy to have it flat from 23Hz-70Hz. The lowest crossover point for Behringer DCX 2496 is 20H...

[quote user="Paul S"]So this amp would not have to deal with a crossover? One R and one L in the signal path, it looks like a headphone amp, maybe a dream circuit for a light piston, HF only, given no cap/coil load at the [ribbon] driver. [/quo...
|
|
So, I do not understand. You took everything out and use it as direct radiator or you still somehow load M4 into a horn? Are pictures how you use it available? Also, how you use it: crossover point and measurable range? I would be also interested to ...

[quote user="JLH"] I do not believe you fully understand what Danley is doing with the Synergy horn. [/quote]
Nope, I do not. Well, I understand it but I am not willing to acknowledge that I understand it as the Synergy horn idea looks too fre...
|
|
I’m absolutely certain that the mids and lows are designed in the same function supporting fashion as I described the compression driver. Danley explicitly explains this in his patent. For my own amusement, I went through all the math and calculation...

As I wrote before I picked some Vitavox S3 driver.
http://www.GoodSoundClub.com/TreeItem.aspx?PostID=8619
and I was expediting with them recently to use in Fundamental Chanel. My idea was that S3 might care LF knee better then S2. In past I had S3 ...
|
|
I know many would view the two frequencies as similar and perhaps of little consequence, but I have my reasons.My primary, driving objective for wanting the horn to produce sound faithfully to at least 90Hz is that 90Hz represents an ideal crossover ...

I've only had the pleasure of listening to 'professional' horns (whatever 'professional' really stands for)--horn normally used in concerts and small venues. (It was always so obvious to me--by listening--that the range of the horn-loaded 'bass...

The crossover is built and will be testing it for the rest
few days. I am sure it will do some “comforting” for my SS amp. The question I
have no answer for myself if I need to use an input active stage. My preamp,
having 8R output impedance can p...

So 3cu ft enclosure withe dims. of Bill (to be made), Tannoy stock crossover. I'm thinking how to design the x-over entry to the sealed enclosure to have the x-over outside without breaking the seal. ...
|
|
Last week found that the distortion I was having was due to some small separations of the woofer cone from the surround suspension probably from age and playing too loud. Applied the glue to them received from English tannoy dealer and distortion...

Had problems 2 and 3 here with my British crossovers
Both speakers have the 78 hz. Dip after a 50 hz. Peak. they are probably room resonances. Try moving the speakers and/ or the mike and remeasure.
Also you ha...

tarted to mount the open baffle for ULF channels at my
attic. The system is fully operational,
not time aligned yet to the degree that I would like it to be but I'm going to
tell you: that Tannoy Red 10 is something that makes everything so sweet...
|
|
By the way, Anthony here is a lead for you. I do not know
what kind Melquiades you build and how you
changed specification for your amp but if you have the one identical to mine
then you had a provision for injection channels which is full range M...

|
Romy, I thought the Ref3 mm-de capos sounded pretty good last I heard them. No idea if they are ported or not. I've been told the crossover is rather simple. To me, they did a good disappearing act. Probably expensive.For dece...

In loudspeaker and amplifier design we could use more channels to have better result (like 12 channel DSet concept) but i never seen any DAC/Pre to have more channels.It seems i am speaking about moronic idea but it is interesting to me think about t...

I shold make it clearer:The Goto was used in a Goto 150Hz horn, crossed at 180Hz.I guess that is a proper implementation for Goto.The Fane was in a 140Hz tractrix horn with a 10cm throat and a not optimised (to large ) back chamber, and no crossover ...
|
|
Sorry I misread, I thought you endorsed the use of PP tube amps with compression horn drivers. Well it looks like were still in the same situation of not making them work. I could go on about why I feel they don't work, but it won't chang...

Ok, none it is time to dive into the practical process of tweeters alignment. Once again I presume that we are taking about monopole tweeters that use AFTER your midranges compression drivers (read my previous post). Some people use term “supertweete...
|
|
[quote user="Paul S"]Do you actually prefer the S2 at crossover frequencies, or is the problem driver compatibility, or is it just too much sound at crossover? If you have the power to burn, why not scrub a dB or two off the ribbon, or ju...

These are Romy's original boxes and scanspeak used as passive radiator. I have purchased 10 inch tannoy reds with their crossovers to replace Romy's which I have given back to him. My Trinnov is doing a 24 dB Linkowitz Reilly crossover at 80 Hz. To m...

I bet it's one of the infrequent posters on this site system . I also find 2khz crossover for td2001 not problematic. Very nice and I imagine it's hard to loose that DIY look in setups like that. Especially when the speaker is undergoing constant cha...
|
|
I think I did find a NEW very good configuration and the one Milq has the crossover modified to reflect the new layout. It very much migh be that it will not be the last one. ...
|
|
Per your recommmendation at your last visit, wish to try using your injection channel with the Dannoy with my horns.Are you using the tannoy only as a tweeter? If so, would you recommend my removing my tweeter and using only the tannoy's, or use both...

A. Wahlsten,this speaker is very well suited for time aligning physically. The more "DSP corrections" that we add, the worse things get. In addition, DSP time alignment can only be useful for one seating position and distance from the speaker. It doe...
