[quote user="unicon"]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 ? [/quote] I was under impression that my criterion is my judgment if what I would like to...

I'm looking to internally wire to binding posts on exterior of box from woofers in a sealed cabinet. I was wondering what are some options for wiring that will not be a hinder. Would a heavy gauge copper 6nine's copper be sufficient? I'm using so...

[quote user="unicon"] Roman, It is interesting to see you using your pipe in room.You mentioned its wrong to use them as LF consumer. You got it somehow wrong1-sealed tube traps can absorb LF and yet again absorb all HF in the same time...2- the ...

[quote user="Paul
S"]If you said anything about your 15" VitaVox in the video, I
must have missed it. What frequency range are you running them, and what
is low-pass filter? Given your prejudices, I suppose the cabinets are sealed,
so they can't...

For what I can understand, your system works as a treatment on the cones surface. In ported (bass-reflex) speakers some of the bass energy comes from the port. Should it be treated as well? Maybe since the sound coming from the port is not phase cohe...

Here's a thought experiment...pick up a couple of chinese orange crate cellos - for example .. http://cgi.ebay.co.uk/Good-student-cello-nylon-bag-bow-ready-to-play_W0QQitemZ190084840261QQihZ009QQcategoryZ10178QQrdZ1QQcmdZViewItemlossily mount the PHY...

I used a set of 2-way near-field monitors and a decent sealed commercial subwoofer in a study room that was quite enjoyable. Mostly listened to FM. That room was not much more than 3m x 3m with lots of alcoves, slanted ceilings and a thick nylon rug....

Good question, what is the actual reasonable output of Dannoy at 50Hz, no idea. To make it clearer, let me summarize my actual thoughts (possibly wrong):
Variant I (PR sub):
1. I accept 20Hz as the lowest freq a...

[quote user="noviygera"]Thank you for your response. I do find myself in a better position to optimize. Last thing is damping inside the chamber. Are there good rules of thumb on this, just like with volume tuning?thank you. Gera[/quote]...if you had...

I except suggestions and critique. I live in Turkey and I am not living in a city, I live at the coast. It is not possible for me to go and experience most of the stuff first hand. There is no one really interested in horns or have multi-way horn sys...

Interesting, at this stage it's early in your testing so I am mostly interested in how they are terminated. Can you provide a picture of how the fluid tubes are sealed and the cable terminated to RCA?

[quote user="Romy the Cat"]Interesting. with sealed 280 sq feet and 8 drivers per side along a long wall you very much migh be able to use a singe 6C33C. With proper loading, good trasformer, DSET and these drivers you should be able to get bass that...

One other nice thing about floor or ceiling-mounting the lower-bass horns is that you wouldn't need such a huge living room; the space would be easier to load (sonically), and you'd have a much easier time finding an appropriate house. Romy wrote :"....

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...

|
Thanks Romy, I'm using a TAD 10" mid in a sealed box to produce 200hz-800hz. Although I'm fairly happy with it, I'm hoping a compression driver/horn would give even better results. There aren't a lot of ready made options for 200-800hz so I chose Got...

Some days ago, I re-installed the Goto CF-1 active crossover (fixed x-frequencies: 220/1000/5000 hz) with the full plethora of my amps....I guess Goto's recommendation is to cross at 220hz then... although 300hz seems to sound better. I haven't ...

While the aftermath of the midbass horn project is not over I am strategizing how I might implement Macondo’s LF section. The leading idea is to bolt a triangular shape sealed enclosure juts behind the small wall that cover the load bearing beam from...

[quote user="Jorge"]Now if you design a TH for 70 hz, you can use it from 35 hz up to 140 hz, and that could match up to your 142hz front Upper Bass horn. With this solution you completely eliminate the need for a Folded horn midbass channel, that ...

[quote user="haralanov"] Congratulations you have found and use this principle, otherwise the back chamber acts like pneumatic brake for the lower working range of the diaphragm! [/quote] Actually it shall act as “pneumatic brake” in a compression dr...

[quote user="AOK_Farmer"] Here's what I've been trying. 8 ohm 4.5 inch full range Omega driver in a 0.35 cu ft sealed box and 6 mH coil 200 Hz electrical crossover. The main speaker is JBL Array 1000. This full range driver has my favorite *tone* of ...

Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).What sonic aspects in particular? ...
|
|
You have said that you want to keep the channel relatively small, and sealed is one way to do it. I don't know your Vitavox, but a larger ("IB") box might have more of the dynamic transcience you mention, and it probably would not be a step back in ...
|
|
Thank you both for your thoughts. The space is interesting: not a cellar, but a sleeping area just big enough to fit a super king size bed, with one of the walls being half open, so it would not pressurize quite like a fully sealed room. Further, it ...

I confess that at one point I tried PM6As in 2.5 cu. ft. vented boxes. Lousy, tipped-up balance and soggy, one-note "bass", contrary to the designer's claims. The only thing good about it was that the box did not add c...

It is unthinkable how mach of great music the Columbia sound engineers had vandalized. The Boulez’s “Verklarte Nacht” with NY Philharmonic turned out to be a good pay but what the sick sound! I bought 3 records and one of them a new, sealed. All of t...

One of the wonderful things about Bruckner that Morons do not buy Bruckner records. Last night I attended the “Hydra” concert and stop by in city record shop. http://classical-scene.com/2011/11/11/sound-in-space-festival/comment-page-1Here it was the...

I am using them with 200 w/channel SS amp in very large sealed cabinets. The room they are in is quite large and the honey bass has been less of a problem than the MF tone. When I play my bartoli baroque CD (live in italy), dynamics...

I have been surprised that you have not already pursued the Zarathustra for your multi-driver, sealed LF. From your early descriptions of both, this seemed like a natural pairing and the most likely way to go, to keep the drivers "off the ...

....obtaining the same extreme results by the different means, although I do not know yet if it is possible….T, I do not think that it is possible to get from 9.5" woofer and passive radiator a good sound in context of small monitor. A passive radiat...
