I note English Mfgrs tried low power ribbon Midrange horns in the 50's (Decca, Kelly & Quad also made one!).These were probably inspired by the hi pwr prewar? Klangfilm ribbon horn (would like to hear one of those!) But, after Peter Walker moved ...

It is right that when you do not have bass problem then why to do any absorption for it ...But how do you know you do not have any problem ?o0 To make it simple and easy just forget about the impedance : it happens this wayyou have distributed mass a...

God, I hate to bring this up as it seems you have given up on your quest for better monitors.Maybe I missed a thread somewhere, but reading over earlier posts you were looking for- high efficiency- tone- dynamics- sealed designZu Credenzas have same ...

Actually it is very possible that it might be so. I made some rudimental measurements and concluded that RAAL tweeter and JBL midrange mounted in the same baffle has non-perfect time aliment. So, I will need to use gaskets under the drivers to time-a...

Honestly there is not enough info here to make a usefull recommendation. If the drivers are going to be used from the 95hz crossover point up then you might not even have to worry about it if the Fs is well below that. I would not do it anyway since ...

I have a few available if your interested. Still sealed in factory plastic....

That's a possibility. Romy, what about the classic LS3/5a design? Small monitor. Sealed box. jh...

Re-reading, I realise you stated your preference for a sealed bass array only in relation to Dreyer's bass horn, not to bass horns in general....

[quote user="starboy"]… though I've always had a monkey/Tannoy on my back which is surprising as I don't really care for box speakers.. [/quote]I am playing now with something similar. I have a small sealed monitor 14 by 24 with an unavoidable 10” Re...

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...

Hi Kodomo-You have made an ambitious undertaking. Congratulations to a brave decision.Can you please elaborate a little on your TAD implementation. I have used one on each side ,in 3 cuft sealed cabinets, first order from 60 to 150Hz, blending gent...

I wonder whether an Altec 416 in a sealed enclosure plus transconductance amplifier would be the better solution for most people/circumstances....
|
|
Romy, I suspect that 200 Hz high-pass will be too low for that driver, even 2nd order, and almost certainly with just 6 dB roll-off. I think more like 500 Hz with 1st order, and might still require the coil.Yellow-type drivers take on and ...

We are closing our new house in 2 weeks and while packing
and preparing to move I am thinking about the configuration of my new playback installation.
I am debating with myself about going with sub 100Hz woofer tower as I
described above vs. intro...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...

[quote user="msaudio"]Your Typical Acoustical Suspension-type Loudspeaker enclosure witch has less then 90 db at 1 watt does not belong with a horn system that starts at 110db at 1 watt, even when you ad more then 1 driver, it is still way to far...

Tube traps are mistakably designed as they tend to deal with a very erroneous assertion that it is possible to feel a listening room with some kind of confused and random bass and then to correct the things with...

[quote user="Romy the Cat"]Not kidding?! :-)Yes, I always felt that Tannoy the vintage 10" sealed box were the best Tannoy out there. Still they were the best not because they were best but because the 10” had less bass extension and did not go into ...

Is Yoshi's box ported or sealed? If it's ported.. of course he's going to be listening to more.. a lot more.. of the box... everything below.. 60hz? is box music.if it's not ported then this is a more interesting discussion. when I first read romy's ...

Romy,thank you for sharing thoughts on the 80Hz horn, giving honest opinion. So if the 80Hz horns are flawed design, I do not want to waste time to improve them. By the way, they are loaded with EVM15B drivers. I am now a bit perplexed on which rout...
|

I think we are all agreed that if time alignment and space were not issues, a bass horn would be the way to go.Now, I'm fairly convinced that the overwhelming benefit of horns in this range is the phase response, ie flat group delay vs frequency. Mos...

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 ...

This stuff has been stuck in my mind for some time now, working around in there against my ongoing experience, against what I am now running. The goal is a more dynamic presentation with better spectral balance, with the emphasis on LF and [more] cor...

[quote user="jamikl"] I recently saw a thread which may have been posted some time back to do with using a reflexbox for mid or upper base. My impression is that you are solidly opposed to using this setup within the rangein which it is normally us...

Let start from the largest drivers and go down. There are larger then 18” drivers (23” and 30”) but looking at this magnet structures I do not find them serious. I addition to make the 23” cone stiff enough requires a lot of diaphragm’s mass or to us...

Here is where I stay with my enigmatic Remedios project. I build inside of top box at resonator that I tuned 50-60 hertz. So basically it is under two square foot enclosure with a port tune at the bottom of resonance frequency. The port is shooting ...
