Two of these $220
http://www.parts-express.com/pe/showdetl.cfm?partnumber=294-605

Two of these $70
http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-7069

So that is a $290 investment.

60 RMS @ 8 handling.
109db per watt.
Is that figure before or after the horn? eek.gif

That sounds very LOUD compared to what I have now, especially considering that I have two 500w@8 monoblocks to feed them eek.gif

If I were to buy such a thing, my concern is not the SPL, but rather the SQ.

Would it really be an upgrade for critical music listening or is it just a loud party tweeter?

The last thing I want is some screechy/honky sounding tops, and be shorted $300.
(I would activate my PV-215 if I wanted that.)

That said, I could... use a nice sounding "party" tweeter as well (Which my PV's are not).

I'm sitting on the fence.
It looks good on Paper. but does anyone have a video of these things in operation?
or more specifically, an A/B comparison video against a regular dome system?

I hate buying everything completely blind and trusting some sheet of paper/chart like it's the word of GOD (metaphorically speaking).

Have you been following the SEOS project at all?
Isn't this just the SEOS waveguide with a DE-250?
DE-250 is the same driver as the Denovo-360 from Erich and sounds great (I use one in the upgraded 4 pis)

I wasn't aware parts express starting stocking them eek.gif

yea the 12 in SEOS horns showed up in the PE catalog a few months ago
also yes the B&C is the same as the DNA-360, check out the diysoundgroup page. many different options people have built stuff with most of the popular 12 in woofers

The more important question is what woofer and crossover are you going to use?

It'll sound good if used properly. If used inappropriately (ie. text book cross over to wild woofer) then it'll sound like poo. That's pretty much any tweeter though, so ya, it's good wink.gif

Check out Erich's kits. If you want a lot of output, the Fusion 15 seems to be very popular.

after you add CD Compensation it will.be more like 98 dB. BTW it works great withthe Celestion 15" Pro wooferthat PE has on buyout.

Here's Sarah McLachlan - Silence with 33kW.
Nobody could stand being in the room if the tweets were any louder! eek.gif Good lord, what do you guys do with such tweeters? You could kill or LRAD-paralyze a humming bird or small-fury-animals from 100ft away eek.gif
Only metal heads would like such a thing, and still be stone deaf after just one day's use.

But one thing is for certain, the tweeter will blow before my monoblocks ever decide to clip as it also does 1000watts@4, and I only use it for frequencies above 400hz.
Three monoblocks: L, C, R

Yes, Bwaslo made up a crossover for that woofer and the DNA-350. The speaker is quite good with an incredibly cost/performance ratio that would be nearly impossible to beat. I've got the prototype at my shop and it's clean and loud! I like it a lot.

I just asked him a few days ago about posting the design, so it will be up by the end of the week. I have to price the front baffles to get the total cost.

I'll be getting the kit lined up next week and will try to package everything in one box for easy and cheaper shipping.

I'm pretty sure they're around $200. I'll have to get things boxed up to figure package material costs. Hopefully I can get both woofers, baffles, waveguides, CD's and crossover parts in one box. If so, then that would help with shipping costs. That would be a fairly big box though.

I can say that I like them better than the Designer Series model that I've been listening to for a while. The woofer is quite nice and the speaker sounds really good. They still need a subwoofer unless you build a bigger ported box.

I dunno, I like to crank up the Noesis on occasion. That CD actually will make you blink when it hits certain frequency's at a high volume. It's a weird feeling and it's strange that it's freaking impossible to keep your eyes open lol. I've had lots of people say the same thing that have come by for a listen. I can turn them u crazy loud but the bass is so loud at that volume it makes the ceiling tiles shake out of their tracks lol.

Blasting brown notes for 10 years and counting!

I'll be giving them (up to) 10,000watts.

I like my sound loud-ish. I have a tendency to blow regular domed tweeters. biggrin.gif

Up to 200w on each the 4 rears, 1000w on the center, and 4200w on each of the mains.
The speakers will change but the amps will remain the same, for now...

So you're giving them 200 watts with 4,000 watts of reserve, lol.

Well going to the SEOS over what you have will certainly get you a lot louder and clearer.

To keep prices low, I'm helping with the front baffles, the waveguides, and the compression driver. The other components are so cheap that they won't help cover free shipping, so it makes sense to just order the woofer and crossover parts from PE because they will ship for free over $100 anyway.


By the way, these speakers have been named 'Cheap Thrills' by forum member Face. I think it's a good name. biggrin.gif
