My man, I am convinced that all you need is time (OK, and money...), and soon you will be dividing that time between full-tilt Beowulf in your lair and spending the ticket money you've saved (clever you!) on La Tache&nbs...

Thanks for posting the Vandersteen interview.It inspired me to try once more to tame my TAD 1601sthat reside in sealed 3cuft boxes. It worked, but the numbersare slightly shocking. 12mH translates to 100Hz, and 25 uFon 4 Ohm Altec 290’s in 260 Hz hor...

[quote user="jessie.dazzle"]Next time I'm making them from a double wall of 3/4-inch plywood sandwiching two inches of sand.[/quote] I do not know if that would be truly necessary. For sure it will not hurt and will be better but ULF that works with ...

Here's a pic (link) of my listening position.When I built my large Bill Fitzmaurice bass horn...I had thought about placing it in that space above the speakers, firing into the corner. I may still do that...but the sub is serving duties in the separa...

OK, that all makes good theoretical sense, and the theories are borne out in terms of sound with OB, BR and sealed LF. But how many people have heard a long horn that was not compromised in fact by what could generically be described as "self-noise"...

I agree the dipol is generally a wrong direction for entire speaker system but I thought it a good way to evaluate a specific driver's sound and character. I am I wrong here? The box should only increase the bass range and provide additional damping....

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...

I finally set it up new Tannoy Red best Twitters. They are sealed irregular shape and purely themselves do not sound bad. They do not have the full range feeling as they had with passive radiator and had a typical red sound of late Autumn leaves....

....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...

I've had a pair of PM4 and GOTO SG30W sitting by cupboard for several years now and instead of just watchinng the foam rot on the Lowthers, I was thinking of slapping the lot into a sealed box for fun. The PM4 would have it's own chamber of course.&n...

So I ordered a Shallco switch from Nebraska:http://www.surplussales.com/Switches/SWRotaryAll-1.htmlAccording to some gurus at diyaudio.com endless Blowjob preamp thread,it seems to be the best human invetion after sliced bread.Let's see. If it's audi...

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...

[quote user="Paul S"] Are you planning to drive the SS lower than the frequency gained by the box? I don't remember the older drivers having long Xmax and/or high BL, or high mms, so multiple drivers and likely more power, not to mention biased X/O, ...

Yes, Sakuma seemed to enjoy delivering some It via "old methods". But he was able to do it not because he used the old methods but because he could use his ears to home in on It. For many years I used Fulton speakers, and Bob Fulton was another one w...

I would like to add this driver to a good driver list:HiVi D10G 10" Kevlar/Paper Woofer, it is sold at parts-express.com and it was one of a few drivers that I ordered for a personal shoot-out. Ignoring the fact that it is yellow and that it makes hu...

I have the CD but didn't get a chance to listen to the B9 effects you mentioned yet, but all the 515Bs and 15" Vitavox I have heard were in larger vented boxes. I think of the dryness you told of as part of pushing a paper driver down in a sealed box...

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:

[quote user="noviygera"]I thought I'd let you know that I ordered four of those Aura subs. Thanks for the advice, if I receive them (I hope so), I will install them into my new listening room. This will take a while because I still have a few mon...

Well, I do not like any
none-sealed enclosure. From my perspective IB box is also sealed and I am not against
it. It is not about the sealing of encloses but about absence of contra-phase feedback
that is always there in any other topologies. Ther...
