This post is a logical continuation of the post: My “radar of sensations” about the “good honk”:

I wonder if any manufactures would be interested to undertake bass DSET proje...

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 all I ha...

[quote user="noviygera"]My mid/upper horns play down to 190Hz. That is -- 188Hz is the Fs of the mid. It's a horn loaded a 10" Precision Device driver. So I need a section (or two sections) to cover the bottom (below 190hz). [/quote]

[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...

In response to my announcement that my DAW went “caput” I was expecting that people would bombard me with advise do not do PC anymore and try Mac. I was kind of semi-ready for it but… not one bombarded me. In fact a few Mac people I know were not...

Again, I do not agree with all notion of Rubber sound that Haralanov seeded. I can not speak what was in the situation that “be” described and 400Hz crossover. I do have the 8” version of 25W driver (I think it is 21W) and my feeling that it sou...

There is always the argument that if you can't hear it, it can simply mean that your hearing sucks.......

Thanks for the detailed answers. I will explain my setup.You are right about the dipole bass correction instead of the injection channel. Since I am waiting for both a subwoofer and the Fane Studio 8M and their horn, I am using the 12" as a b...

It is not surprising that the subject of horn is as screwed as the subject of drivers. It is understandable as driver must be made for specific horn loading, not one make drivers properly, so what the horns are made for?
A horn is a very simple dev...

[quote user="jessie.dazzle"] For a lot of reasons, I'd vote for an alternate placement. You've got that basement, so why not use it as a rear chamber? You might be able to use the volume "as is", without building a proper rear chamber. In this ca...

My 18-cell is a classic 18-cell very similar of the one that the guy from Sweden built:

The difference is that my multicell has 3 extra cells and out...

[quote user="guy sergeant"]One issue that I would consider is that the Tractrix profile supposedly does not lend itself aswell to extremely low frequency horns (being too short) as other profiles in particular the Hypex (Salmon) shape. [/quote]
Yep,...

Ah electrostats...I am fairly sure that problem with esls is trying to take them down to low and them not being driven properly. If you actually calculate how much current you need to drive transient peaks into an ESL, it's horrifying. I can't imagin...

The first level of listening perception is Static Level. At this level a listener perceives musical information as a collection of the individual sounds and a listening awareness tries to evaluate the “convince-ability” of those sounds. At this level...

[quote user="ulf"] Well, it was not really a surprise to us that the horn without the phase plug was dissapointing. Without the plug we had a horn that was a bit too short, had too large front cavity and less compression than we desired. [/quote]

Looks fine, Anthony. I am not sure what resonance frequency tells
you. Anyhow, a great advantage of your pipe topology for LF is that you will be
able to pile up as many drivers as you need in order to hit the desired
reference DB level. There is...

I need to give it to you and I need to retract my comments
about your bass pipes. I did find them to be ugly in your prototype drowning
but assembled I find them look very present, in fact quite wonderful. Connection al, of then in parallel is goo...

I think my dysfunctional one 15” driver in my Midbass was
for a while and THAT was something the make me to feel that I need to move
Macondo to 9-9-1 position. With the recent changes (recovery of a woofer,
recalibration of channels, EQ of the mid...

[quote user="Scott L"]Romy's bass
driver array is actually a very good approach. 6 x10's per side is actually
enough to produce an acoustical watt at the upper part of the range they cover,
but not down to the subterranean depths of an orchestra's...

With all my domesticated obligations I did not have neither time

“A large room, open to the
stairs, maybe a dozen watts to play with” that was exactly my concern from
beginning. Of cause I could employ a more powerful amps from bottom but it my
case it would be under 100Hz and it would be a big white flag. So, ...

John, I am not sure that I can talk in generalities on the
subject as for a quite few years I stopped to monitor the market as attentively
as I did years back. It is very possible that something new come to existence

*** I am positive that if
you get 100 pieces of exactly your model of Tannoy, they will ALL sound
different.
Very likely, I have 6
drivers and one of them sound as I need, all the rest of them are compromised.
They still have the similar char...

Anthony, I am not so thrill
that you are unlashing your into this direction. Not that it is my business and
you can do whatever you want. Still, I feel that methodologically it is not right
way to build a playback. What I mean is that to evaluate ...

user="anthony"]I guess I am lucky that the Bass Cannons can be run
off 9w from the DSET bottom channel and from memory I get about 115dB at 18Hz

small room. [/quote]
