Come on, Thomas, no one talks about the 75-85db of gain at MM level. However, the higher gain does has some things that I find is very useful and I find it is much worth to burn extra 15dB in prams then to have a preamp wide open and run photo at low...

"A tweeter positioned inside the MF horn"I wasn't sure how that could be done effectively but was looking forward to a creative solution. That photo image is not what I expected; on hindsight it is not a surprise. Of course one could rip the tweeter ...

Automotive seats typically have smallish, adjustable head restraints, and the seat backs recline. Take a look at this:http://www.bookofjoe.com/images/2007/10/22/1ewtrety.jpgNote that the support integrates arm rests. Yes one's butt would be a bit low...

Mats, I must have missed something. What do you see in the Audiotekne photo that you ask after the bass box? My usual ADHD glance only took in a double-wall-with-double-cutouts front baffle(s), and the (small-ish) size of it; maybe some sort of BR ...

[quote user="serenechaos"]I built a pair of tapped horns, as per John Hasquin, designed to integrate w/ mid-bass horns (cross over ~ 70-80 hz). Loaded in the corners, the low bass is well supported, and, they "dissapear" sonicaly. By that, I mean, ...

Romy, the main driver in this acoustic system has nothing to do with the funny Lowthers. It is very high class field coil speaker unit made by Oleg Rullit. Take a look:The owner of the system has tried the highest class of the Feastrex line of widera...

I finished the second prototype and finally can listen in stereo...and start the fine-tuning...only problem now is to reduce the input sensitivity of the temporary tube amp so that I don't get blown away at the first notch of the volume control ;-)

Can I have some opinions on a potential mid-bass driver for my Altec 515s, as pictured in the attachement? What are the obvious or potential problems I should address?see attached photo: 120 Hz - @800 Hz.For the Altec 515 such a horn should be ...

How do we hear?
A recent article examined the capacity of the optic nerve to process visual signals. Based on the number of neurons in the retina, etc., an estimate of less than a megabyte of information was found, which is surprisingly low. This...

Hi Josh! That was basically my idea too. Although I read that the 12 inch driver loses directivity after 750. But I played around with Behringer dcx 2496, and I had the impression, that 1200 second order was the best sounding. The main reason for cro...

For a large horn like this you can't glue all the rings together and start turning because the imbalance wil shake things to bits plus you have to account for where the cutting tool can safely and physically reach. So the process is to glue a few ri...

Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order high pass on them ...

I have been quietly listening and working on my new system. The upperbass horn can be crossed lower than I anticipated, which is great news for me. I was going to have the crossover point of 160hz, but I can easily do 120hz :) The dual tad's will be ...

Kerry, from what you have said so far, I am not surprised that you have gone whole-hog digital. I see that yours is an HT system. The first thing anyone here would say is, physically time-align your HF, although I suppose you "could" do that with DEQ...

Domidaw, you are looking at the right things but there is something to consider: when you put a resistance meter across a discharged capacitor you see a low resistance initially because the battery in the meter is charging the capacitor a little, so ...

I'm thinking about trying to put together a Melquiades amplifier for myself. I printed out a copy of the schematic (thanks for sharing). I have a simple early question. Both the 12.6 and 6.3V windings for the filaments are shown as being center taped...

Thanks Romy and JLH for your input :::: It seems very likely that in this application (100 - 1000Hz), the return on my investment may be small to nonexistant, and that I may be wasting my time in trying to create a smoother transition :::: Looking at...
