Very, good, now I a clear pictures of what I will be doing and all that I need now is to spend some time on phone with London trying to find out where I can source a dozen or so those “unique” drivers on mine…. The 70-20XR tweeter will be arriving in...

[quote user="homebuilder"]...active EQ will be a part of this project, along with in room measurement. My friend will do the honors on that. I have not purchased an EQ yet. [/quote]
You might eventually revise your view about the active EQ and pres...

Skushino, Thanks for pointing it out. Unfortunately with all my desire to understand what CH Audio did turn to fiasco and I absolutely do not understand this LF section. Is it a duplex of 515 drivers with one loaded in this front shallow front horn a...

Here is the set up working on trying to lower mechanical excursion w/o using large horns:5 way system. Crossover points are 40, 100, 750, 7500 the vertical JBL array 1400 mid horns have a horn tweeter built into their top. Yes the 15-40 Hz channel a...

Looks like the phase response is quite complicated, with two phase flips between the knee and the Fs notch, but the PR phase eventually comes back to be in phase below the Fs:
"I
am sure we have all heard that a passive radiato...

Playing with B-2 power amp I made an experiment and instead of loading to it the MiniMe Bass section I loaded the B-2 with Macondo’s bass arrays. I made add-hog attenuator and coil to EQ MiniMe MF with Macondo’s bass and gave some listening. It w...

Romy,
More to come soon but a couple comments regarding bass horns ( and one on Tractrix horns ) :
The Edgar Seismic subwoofer ( 18" JBL E155-4 hyperbolic-exponential folded horn, 40 Hz Fc ) works very well in my room - much better than the 1...

Romy, does it not seem that the things you hear with ported bass would only be magnified/multiplied if you added significant enclosure resonance up the frequency range? I am the same way with horns, in the sense that I hear the damn h...

[quote user="Jorge"]Actually a Tapped Horn would be bigger than a sealed enclosure, here is one of my first TH tests. The sound is very different than the sound coming form a Sealed encolsure. My first impression was that the bass was gone! There...

Hi Mats,I am not using 4 on each side. I will be using two on each side. Until now I always liked sealed enclosures. However Tad drivers are more suited to ported configurations. If you do not push them to go too low and have a reasonable fs point, t...

Romy:Thank you for the reply. First, a correction: I have a pair of TAD 1201. The MTM idea would utilize other drivers, such as the LE-8, 2118, etc. I'm certainly not against buying another pair of TAD, however.The 1201 w...

Tax, do not go over yourself with “building paranoia”, looking for drivers, horns, boxes and etc. If you are looking for 80Hz to 200Hz range (you will need higher upper knee for AG Dou) then you do not need a bass driver with Resonance frequency of 3...

I have explored the subject of tapped horns. My exploration did not include listening them – ridicules, isn’t it? I did consult with a few folks, who I respect and who built and heard many of them and who know subject well. I pretty much know what I ...

Romy, I picked up a pair of FX120 and F120A drivers over two years ago. I initially spent some time with the FX120 in a small 10-liter ported enclosure (similar to Fostex' recommended one but altered dimensions). After many months of liste...
|

Sorry Robert, Your opening line on "Good luck getting midrange from F120A for non annoying monitors." tended to set the mood for the rest of your post in a negative light for Fostex drivers, the F120A included (at least for me it did)...

Thanks, msaudio, for sharing your experience with Aura and Hartley. I do not have Hartleyes. I heard them I think twice but person the people did not try to get out of their playback anything that I care, so it is hard to say anything. In contrary I ...

I would like to think a little about the monitors. A monitor is kind of bogus name but useful. I usually call a loudspeaker that is not floor standing as a monitor. Sometime they called bookshelf but I hardly image any loudspeaker on a bookshelf…

Ok, at this point the design idea about the Macondo’s Pilot sections are formed in my head. It will be two way MMTMM or MMMTMM configuration with extremely low footprint that would be perfectly integrated (as add-in) and “hidden” into the Macondo’s f...
|

Hmmmm, not sure what to say in this case. From a higher view (and do correct me if I am wrong), you seem to have a general dislike for Fostex drivers. I can also sympathize that some of them are hard to listen to. In any case, you bought an exp...

[quote user="zanon"]Romy:I was not aware that manufacturers of multidriver system let you attenuate individual drivers. I guess if you multi-amp, then you have control at that level. I have never encountered such a system so I cannot say, but if it i...

[quote user="Romy the Cat"]And it is not that you can do it but it is a very common practice. Some manufacturers offer actuators of sometime tapping pads. I think even the largest Wilsons offer a set of series resistors for crossovers to attenuate HF...

It uses at the buttom a regular sealed or ported box and the driver as direct radiator but they also put the speaker on the spikes and made the bottom looks like it is a horn output. Also at this larger model[/quote]On the smalle...

For my ears, the piano is rich in harmonics that change with playing volume BUT the only way to get a louder note is with the hammer striking the strings more powerfully which always is coupled to a louder "articulation". Violins and wind instruments...

Yes of course, rule going to be very much in play and certainly it will be impacted by specific response right and left channels to a given location. Even though the location is hugely variable and the speakers might be moved with the freedom of 6-7 ...

I think correct positioning the watt puppy and maxx model in room is not easy and each time i listened to them i sensed a bloated sound, I guessed bloated sound refer to acoustics. i know these model drivers are not fast but i guessed in a good room ...
