lately I've come to theorize that the horn midbass may be a contadictive dead end approach. The reason is that proper horn midbass (lets say 80 to 400Hz) will be a big one and present a few inherent "brick walls". It will physically shade the midrang...

[quote user="Romy the Cat"] A few months ago I bought the first pressing of the same album… only sealed (paid $60 - love Horowitz in the end of 40s begin of 50s)... and you know what? Suddenly the entire album could be perfectly tracked with the cont...

Good start Dan!The JBL phenolic 2" driver is 2482.I would lower the crossover point as far as you dare, 300Hz or so.Now the 2226 will do what they are pretty good at.Later you will likely want to filter the 2445 around 2k.A 600Hz horn with a 1" drive...

Thanks for the wolves- and power tips!I don't know any industry wolves unfortunately(?), but more new -01 drivers have appeared at half the price. I think I'll go ahead and make the speakers full range in time for my upcoming 30-years-on-earth-c...

Funny, I was just thinking about battery powering of amps... I know you have identified that the problem is more with the sources, but it would be interesting and quite feasible with the Melquiades and other components... wouldn't want to try it...

Thanks Romy,Yes, I received your advice in the past privately regarding proper size for 1808 enclosure, and I thank you for pointing me in right directions. Yes, sealed box is simple calculation using e.g., WinISD. I am experimenting with&n...

Well yesterday this miserable Catographer was cleaning out his garage when he made a instructive discovery in the beer refridgerator out there. I vaguely remember un plugging it in April during a suspect electrical project, but what I ...

Hi Kitty,This combo is quite interesting and amazingly coincidental....I had scan speak 18W's sitting around from my old speakers and just recently had them put in sealed boxes. I was using a Seas silk dome on top (in free a...

The least offensive result I have gotten from a ported speaker was closest to the yellow option. I built a pair of small monitors with ports on the top purely because it was the only way they would fit. I cannot reasonably e...

As a builder I can pre-warn you that this could be a fairly complex and very expensive proposition if done in cast concrete. For that matter excavation, per se, is expensive, and municipalities differ about what you can...

[quote user="Michaelz"]I know that piano sound board is very expensive. How ever, one can get brken old upright pianos for free, or for very little (except you need to have a truck to move them. No clue for lack of time though:^...

I just stumbled on this thread, and am thinking about being your first customer.I am planning to move to New York from Tokyo end of this year - not just escape the nuclear radiation but to let my kids experience a different culture.Depending on m...

[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 ...

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...

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? ...

[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 ...

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 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...

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 ...
|
|
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 ...

Thank you for the description. How they are sealed is what I am most curious about. I've tried a few different techniques to seal fluid in the tubes during my cable experiments. Does it look like they simply injected a clear silicone, terminated to R...
