Well, the only thing I can think of is to seal them and keep 'em that way. I've made only a couple of vented enclosures and they have all ended up being sealed or severely aperiodic. Even if the Mini's are moved back, it is unlikely that they would...

I have order 4cu feet sealed enclosure for two 15 drivers. It
is relatively small box but I need to hit minus 6-8 dB at 50Hz. The collection
of the drivers I have would be following: Vitavox AK51 and 15/40, Altec 416B
and 515B. I like Vitavox tone...

[quote user="rowuk"]In live music, we have intermodulation. Two trumpets or a trumpet and oboe playing together create sum and difference tones that change depending on pitch interval for instance. For music in major keys, this intermodulation is add...

My mood swings around this Remedios project are remarkable. Literally a few days ago I meant to trash the whole things and start from scratch and now I again am super enthusiastic, unhealthy enthusiastic. Paul was right to fix 6-in baffle will be pa...

Okay, here's a graph that shows theoretically what will happen when the volume is doubled and a few other circumstances. It should give you an idea of what's going on. It is important to note that when the Vb is doubled, th...

T, also if you knockewd up a small monitor then let me give you a lead that you might or not might find worth attention. I did a few monitors in my past and I have learned that whatever boards or woofs I used it always had sound and partially if you ...

I too want a monitor speaker to play with, especially for amplifier experimentation.I put another 4" Fostex in a sealed "box" (globe actually) and crossed it over at 150hz to one SS 25w/8565 on the side. Wishful thinking? -Yes.About 88-90dB sensitive...

The first thing that comes to mind is what is the range that the drivers will cover and what is the Fs of the drivers.
Another thing to consider is the loading type on the bass units you have.
I take it that they are sealed ? If so I would not con...

What I would like to see is as usually does not exist but I would like to see a regular cone full-range loudspeaker objectionably made for use with a single powerful SET.
What I have in mind is a sealed enclosure the size of Dunlavy V or VI, 4-5 way...

Greg, I have written about my "DEBZ" speakers several times at this site, including Post ID 3269, early in my original Lamm ML2 thread. I mention these speakers now to compare what we are aiming at here to what I have already done, wh...

If the setup is semi acceptable, after ten years one should lose the evaluation part of listening experience and treat the system like a kitchen radio or car playback and simply enjoy the music. I think ten years is a minimum to achieve the position ...

Similar experience but I get to keep my "old" room. I have just changed my 5 way horn loaded down to 140 hz speakers to a friends room twice as big as mine, with an open back area into the house as your new room has and one side and the front have hu...

Yes, for practical reasons, one side of an IB driver is usually "wrapped and sealed" to deliver lower frequencies from the other side, since it is generally impractical to actually make a baffle large enough to prevent sonic shorts. However, at high...

[quote user="jessie.dazzle"]When doing the final assembly, you might want to use Nylock type self-locking nuts:http://www.nylocknut.com/Looking at the images, this might require that you use slightly longer bolts (the few threads exposed beyond the e...

[quote user="jessie.dazzle"] I have 2 ULF "boxes"; each has an 18" McCauley 6174.
The enclosures are sealed and each measures 14 cubic feet. They are made from 70mm thick concrete blocks.
Power is from a pair of M1.1 amps (100 Watts each)....

When my midbass horns projects will be finished the horns will be peaty much organic part of house and without looking at this thread an ordinary person would never understand what is behind and what it is for. When we look at reasoning for Carnac St...

[quote user="Romy the Cat"]I woke up and thinking about the horn problem with fresh head I am thinking what did wrong. I did not measure the frequency response of the horn – I did not see a need for it – the sound of the thing is way beyond where it ...

I have posted this idea at the Peter’s Vitavox site a few month back but there is no activity at that site. It sucks that there are no advanced S2 users out there. I am planning to try it myself and in a month or so and will report the result. ...

I love not only the beautiful results you are getting, Jessie, but also appreciate that the methods you are adopting allow you to continue to refine your horns on the fly. Particularly nice, to my way of thinking, is that you can tune your horn...

You and I now have what seems to be very similar situations; similar MF and HF channels, in a room of similar size. However, I still have no operational dedicated mid-bass channels; you do. I have dedicated lower-bass channels; you do not. As is ...

Richard, I absolutely agree with you that dipole provides a masking affect from many problems but along with illumination of the badly reproduced bass dipoles inject into music a common denominator of… dipolenisness….. and this something that ...

Hello every body, I live in France and I'm new on this forum.I'm thinking to build (some months) a mono big Single Ended amplifier (200-300 watts) made with triodes (IDHT or DHT doesn't matter for me) for outdoor professional audio.Have you got an on...

I wonder what kind sound not-impacting methods exist to connect and disconnect signal from moving coil cartridges. If we are talking about the switching the .1mV signal and monitor the results within a fairly high capacity playback then it beco...

I just received mine on Friday. I am amazed at how easy to use and this machine is and how convenient it is compared to my old VPI. I always dreaded cleaning records with the VPI. With the audio desk I put the record in, push a button, come back ...
