My Home Theater Upgrade Vlog 1

[wrenchmonkey26]

Those X-overs look well built. (btw, the "spiders" are most commonly known as diaphragms)

[CharlestonChew03]

Sounds like they are gonna be nice speakers. =D

[theblackhand2]

This is a project that slowly evolved over a very long time, So I haven't really kept tabs on exactly how much I spent in total thus far. But hi-end audio and video can easily cost tens of thousands of dollars.

[musicman257]

hey blackhand.like your hometheater.can spend all day in a room like that.ill bring the popcorn.okay.lol

[lukeslandspeeder]

understandable. hope you get it the way you want it to sound. good luck. 8)

[lukeslandspeeder]

those drivers are shat. u need full range wizzer cone drivers with subwoofers.

[theblackhand2]

They only good full rang drivers drivers with the performance characteristics I desire would have cost me a small fortune. So I had to drop them from my shopping list and settle for two ways.

[KAISERKRAUT]

Vifa are good components to use, but I question why people who do obviously have some clue as to what you are doing, are still building ported/vented boxes?

Perhaps its your first building.

None the less, I challange you , 5 years from now, to craft a Transmission line Design speaker enclosure using Vifa components,crafted out of ABS Plastic(a fantastic material for enclosures)

I think you will realize the potential, after listening to some Transmission lines at your local audio shop,

[theblackhand2]

I would love nothing more than to build a set of transmission line enclosures. I've heard a pair before and the bass had a very nice open natural sound that was indeed far better than any conventional design. Unfortunately I don't have the room for them nor do I feel secure with the lack of predictability in the mathematics used to calculate the tranny line enclosure specs. Maybe next time I will build a set. But for now I am very satisfied with the performance of my current project.

[KAISERKRAUT]

Good comments,

I will rehash some lessons I learned long ago and it got me interested.

The secret to a good Transmission Line is in matching it to the speceific woofer.This is done by obtaining the measurement of the woofers resonant frequency(the tone that the woofer naturally "rings"much as a bell does)

This measurement is supplied by the manufacturer as the Fs parameter.

It is then a simple matter of determining the correct length for the transmission line.

There is a formula to use.

[v8malibu]

The white components are resistors. The inductor is the coil of wire.

[Frostman182]

Vifa is kick ass stuff. My paradigms have Vifa drivers and they do take a beating! Good luck!

[theblackhand2]

I do have the first two speakers up and running. Indeed vifa is awesome stuff. My highs are crisp and very detailed, mids are very clean and natural, and bass is nice and taught. Overall the sound stage is very large and airy while maintaining detailed fidelity.

[MrDeverill]

Looks very nice, very professional.

Got any tips for making a kickass subwoofer?

[Foxontherun2]

I got some Alesis monitor ones that look like that , they sound great. Also have some Alesis point sevens sound good too, but didn't have to build mine , lol. Weird that they come all separated , are you going to carpet the boxes?

[theblackhand2]

We are building the cabinets ourselves based on a computer generated plan provided by Meniscus Audio where I bought the parts. The finish is going to be African Mohogany. One thing to remember is that most speakers found in premium A/V stores use the same drivers and components from the same sources we Audio DIYer's order our parts from. The big difference is that going DIY results in Audiophile Quality loudspeakers without the enormous Audiophile prices.

[Foxontherun2]

luckley I got mine for free from my dad otherwise they would have cost a bundle, lol. Are you going to put the yellow insulation on the inside? I notice both mine have this yellow insulation inside them so the sound doesn't echo in the box I guess.

[theblackhand2]

I'm planning on lining the walls of with a thin layer of upholsterer's stuffing to reduce standing waves and do further deaden cabinet vibrations. Then I will use Acusti-Stuff batting to damp the enclosure. This combination should keep the fidelity of bass and lower midrange clean and tight and not harsh and overly boomy.

[Foxontherun2]

A piano black finish would look cool , but would be hard to keep fingerprints off of , lol
