Stentorian build - Page 4

Then Duratex it is!

For a gift like this, would it be appropriate for you to simply seal then up and include an offer to finish them after Christmas? Then you could ask the recipient how they would like them finished without ruining the surprise.

If that isn't an option, I would suggest you simply spray a couple coats of clear poly.

Flat black.

Easy, effective, universally liked.

As always, an excellent job em......Dusty! Coming from my days in the profound field, corrugated metal grills and Duratex should do the trick. They'll bring less attention to themselves on stage and should be durable enough to last a few years. And before you finish em don't forget pole mounts, recessed handles and corner guards!

No need to do it yourself as it requires a special gun and it's messy. Just take em to a Rhino Liner place and let them do it. Hardware I mentioned can always be added later.

a dome tweet in a pro audio app with no protection seems like "bye bye" to me. why not series a fast blow fuse in line with the tweet or even a "light bulb" limiter?

question to the designer, not to mr. shopfloor.

I didn't think about that. If he's using them for DJ'ing or pro sorts of applications I would think that a CD would be a must.

Can you elaborate on what the use is. Pro DJ in small venue.

Dance club?
Light background jazz during lunch?
Easily portable necessary? Or stays put at a club?

Even Curt says on his page it's not a dedicated pro device. It's approaching pro use. It's HT/Pro use. I would think more than 100 watts would eat that $12 tweeter quickly.

Any chance you have 8, 10watt, 8.8ohm resistors kicking around. Using 4 resistors instead of 2 4.4ohm resistors might help power handling of the xo. Mind you, using 2 resistors is a bit of built in protection. As they heat up they'll resist more. And possibly burn up with enough power flowing through. Just be prepared to replace those for him if it happens.

The xo point is about 2200hz and the Vifa spec sheet says 50watts long term power handling. I would think pro use is long term power handling. But how much of a 100watt amp reaches the tweeter? Probably less than 50watts in typical use.

I'm not trying to scare you. Just offering advice. I would think you are in general ok here. Depending on his use. I'd just hate to see him take home his new toy and pump 200watts continuous rap through them at 120db and then something go pooofff.

Will he have a sub for these? The enclosure Q is a little on the high side. Bass extention won't be good. From Curt: "I still recommend using these
with a subwoofer, but they shouldn't disappoint if you don't". That was listening in his home. Depends how small is small, and what for of music.

Pro audio is a different beast

EDIT - Consider this http://www.parts-express.com/pe/show...umber=248-6700

Might be more than he needs. But has options and enough power to make these smoke.

Might be worth having a few spare tweets in reserve.

Ok, those upgraded resistors should help.

Hmm, I thought he'd be spinning or something. Guitar and (male) vocals don't have much content above 5khz. They do have a lot of content around 2khz though, which is where the tweeter would feel the strain.

I think they'll be fine. For $200 they're sure good. And will look a lot nicer than any pro stuff. He'll also be able to throw them in his HT when not playing gigs

Just to put it in perspective what real pro gear does, and why some here have questioned the pro use of this a little... A typical 12" guitar speaker (only 1) is about 100db sensitive. If the sentorians are 94db, that means it would take 300 watts for the sentorians to do what the typical guitar speaker can do with 100watts. And if you had 2 of those typical 12" guitar speakers, you'd only need 50watts to equal the 300watts. A lot of guitar players use a stack of 4 12"s only needing 25watts to equal the sentorians.

MKTheater has the BFM DR200's and he says they're fantastic!

wish i had your skills and tools.

amazing work. can't wait to see how you going to finish them.

Do you happen to need any new friends to do projects for? If not, can you please donate some of your unspent skill to me? I bet you have a cache of extra for rainy days. lol I always look forward to your builds. No matter what you call yourself at the time.

Chris

and they're a very different type of build, which could be fun to build

Nice looking build man!

I would think these perfect for light acoustic coffee house type venus with a subwoofer....

They might struggle over a set of drums though..... If so hand him a set of cat tails and stuff his kick.

Dusty (PI),

I really like your shop table, did you build that? Have any plans/details?
