Rowuk,
When you say "electronics with better performance" are you referring to something like this IC driver board?

|
It's certainly worth trying. How do I choose the proper value of the attenuator? 10K or...?...
|
Paul,My current active crossover is a DSP unit which likely has low enough input impedance and single ended inputs. I added BAL inputs by using input transformers. By no means do I want to use this combination as a representation of my crossover! I i...
|
In my situation there is a missing link between my single ended phono stage and my balanced active crossover. Between them is 35ft. of interconnect. The missing link is indicated with "?" in the sketch.What I need is one single-ended input, some atte...

To me, getting good sound from 50-250hz with one channel is almost a victory. That is exactly what I am unable to get in my system. So even though the aim is wider bandwidth, if the Jubilee is good for 50-250hz, within the context of high eff horn sy...
|
I've been thinking about trying the Klipsch Jubilee. The idea I have is to replace my bass channel (Aura 1808 in reflex box) together with midbass channel (Funktion One F115) with a single Klipsch Jubilee channel. Of course I'm talking about stereo p...
|
Yep, the IB sub does it's job, as I expected because I had an IB sub in my previous listening room. I think you will really like the bass of this configuration because from my past experience -- there is nothing as good as IB sub for low bass, for lo...

TAD TD-2002:I have been evaluating these without horns. Essentially, listening to them without the horns, but also with original horns. No difference, as I will describe what I am hearing in both configurations (applies to their high frequency reprod...
|
Romy, thank you for your thoughts. First off, my further thought on the system and specifically the implementation of the high freq section: Yes, the time alignment would be a challenge but possible. This is the main compromise, in my view but the le...
|
I have identified a direction for my next speaker system. Whether it is a good one or not is a different topic -- I think it's a good one because I've lived with my current horn system for 10 years and have since developed an understanding of it's st...

Maybe it's time to re-read Robinson Crusoe. It sets the context for seeing life more soberly. I too, need to clear up space so that the possessions don't possess me! And I get upset at my kids for not cleaning up......
|
I agree the dipol is generally a wrong direction for entire speaker system but I thought it a good way to evaluate a specific driver's sound and character. I am I wrong here? The box should only increase the bass range and provide additional damping....
|
There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple of days. I install these...
|
I am thinking that there is an explanation and it has to do with a narrow sweet spot, where the large system sums properly with reduced amount of chaotic room reflections, with a smeared timing. I noticed a similar effect with my system and if I redu...
|
Now that the preliminary excitement of my ingenious idea wore off, I'm ready to share it and accept the harsh reality of any shortcomings... but seriously.
For a while now, I've been been working on optimally integrating my 3 channel...

These are 103db efficient 15" midbass boxes. It's a band pass horn design with narrow bandwidth of 60-250hz. No port thought, it's a sealed box with two chambers in front of the driver. I do not know how they sound but, myself interested in trying th...
|
Romy,What was the reason you were not happy with the last version of your midbass section? THe one with two Vitavox 15" per side. ...
|
Flip the Vitavox woofers so the magnet is on outside of box and the cone is facing inside. This will increase the overall box volume and maybe reduce the mid/high output. Also voice coil will be closer to time aligned to rest of system......
|
Do you have the speakers as pictured already in place, or at least in the form your beautiful rendering shows? I would recommend to try a mock up of this layout in your room and not proceed with the full custom build. For example, I don't think the a...
|
I realized you meant Midbass when you wrote MD. I agree that letting the midbass horn run full range on the bottom is not a good idea. My point was try the bass channel (Aura 1808) run much higher and share the same crossover as the midbass when cros...
|
I want to share what I feel is a good application of an injection channel, as introduced by Romy. But this is different and also useful and i can tell you it works and very well. Of course, I do not recommend to use this application in the same exact...
|
Romy,
I tried non-symmetric crossovers (freq and slopes different for channels) but had to go back to symmetric because the phase response sounded very wrong to my ears. I learned that I could get used to a bad fr...
|
Toddlers are the best! You got him a great chair, but now you need to lower your top channels so he's no missing the highs. Or do they cover evenly that low, so he's in the sweet spot too?Gera...
|
I feel I can note here my diffuser findings. I would recommend a polycylindric type diffuser like GIK poly. I have them and I like them much better than the QRD type diffusers In my room with horns speakers. The poly is much more gentle and unnoticea...
|
Romy,I understand your situation as a result of the move. It is a good thing because a system that is out of proportion with not work in a family environment and ultimately you will be battling yourself between sound and family priorities and practic...
|
Romy,I think I'll try your suggestion. When you say "mappable transformer" do you mean one with multiple primary taps, like 3.5K, 5.5K, 8K?Gera...

After planning out the exit strategy for my DSP crossover, I am resuming my first Single Ended Pentode 307a tube amp project, the one mentioned earlier. I'd like to approach this with a certain degree of understanding so I have re-read carefully all ...
|
I would be most concerned with having the turntable where kids can reach it. This has proven to be very problematic! Son climbing speakers -- not a problem....
|
Maybe make a manifold and mount drivers vertically in push pull. No sagging, much less vibration. But I would not use fiberglass insulation behind the bass channel and remove any existing fiberglass in that area, replace with cotton/denim insulat...
|
I had a similar setup with an IB subwoofer, 2x18" woofers, behind the listening area -- also time aligned. It's works ok. But it will excite the entire house structure if you play loud -- you can be sure. Everyone will feel it. But that's not the iss...
