I rarely (maybe never) seen a DIY design that uses the ScanSpeak D2008 or D2010 20mm dome tweeters. I think these are similar in design to the Hiquphon tweeters. I know the spec sheet for the Scan's rate their power handling with a 2nd order filter …

I asked Bryan at the 2019 MWAF if Dayton Audio had any plans of making a higher end 3/4 inch tweeter. He said it was not going to happen - not even thinking about it. I understand they discovered that the profit margin if better on larger drivers. T…

The other side of the equation is the number of DIY loudspeakers builder is not growing - affecting the demand for drivers. The good thing about Dayton Audio is they still care about the DIY community. The new driver on paper (website) looks good.

Whoops, I meant the Woofer to Midrange XO at 200-250 Hz
-
+1 for the Seos/830883/830884. In my opinion the upper limit for any 6.5" woofer is 2.5Khz due to beaming ! would get the largest round-over router bit you can get to put a radii on the vertical cabinet edges to help with diffraction - I think …

Your speakers look great. I'm curious if there was a reason you used Particle board other then the low cost? I think if a cabinet is properly braced solid wood like oak doesn't have much of/if any issue with resonances.

It's the bottom section of a bean can to shield the toroidal transformer.

I installed the new tweeter today and switched from using my DIY electronic crossover to a MiniDSP 2x4-HD and it's nice to have so much tweak ability at your finger tips. These are my speakers I called "Notes" that Won in the unlimited cat…

It is the same woofer I used in the Omni direction speaker with the PS95. I brought that speaker to MWAF in 2016 and won in the under $200 category. (Image)

I know it's weird but there is no resistor in series with the tweeter.
-
MS Excel - Line elements for the wires and pictures from the drivers, Inductors and resistors. Text box's for the labeling. I do my design in Passive crossover designer.

Scott your Hafnium design did inspire some of the elements of my design after I decided to use the Peerless TC9 full range as a mid-range and the OT19 tweeter. Both are very good performing drivers and low cost making them some of the best drivers f…

(Quote) Under $300, I may need to ask PE if they will reinstate my status at PETT.

My speaker design competition scoresheets were sent back to PE due to the street address being incorrect. Vivian Jones at PE scanned them and sent them to me today. My speaker design is called Peerless Uncubed (3-way all peerless drivers in an encl…

(Quote) Yes, they were called the two cherries Dayton Audio RS100P-4 and ND20FB. That was in 2018. I have been to the Iowa event a few times. I think I met you; I think your name is Craig. You had an MTM one year that used the Tang Band W4-1320SIF d…

Thank's guys for the positive comments. I overreacted and didn't realize until I created a lost mail request at USPS that the auto address fill in function on my computer put in the wrong street number and it was wrong on my speaker registration fo…
-
(Quote) Thanks - I bought them, my other option was to replace both tweeters with the Peerless OT19NC. But I would need to rework the crossovers and possibly need to 3D print new waveguides.
-
I have not used this driver but looking at your measured DATS data I don't think I have had a driver measure that much differently then the spec sheet. The spec sheet says it has a Kapton former which explains the high Qms values (High Qms - low ele…
-
This is an interesting idea. I'm not sure how well it would crossover due to the extra group delay. I would think that a transmission line might be a better idea to get more low end extension from a tweeter. I think many high end tweeter made today …

I hope somebody buys the design and tooling for the ERSE Super Q Laminated Iron core inductors. Currently they are all on back order at PE. It's sad to see another supplier go out of business we need the competition to keep the cost of parts down an…
-
I think I'm going with the propeller posts. I like the Tellurium copper for lower resistance vs brass. I think some of these manufactures that make brass posts should consider advertising which alloy they are using. Free cutting 360 brass has 60% co…

I took a look at Danny Richie's Tube connectors, I think the concept make sense to shorten the signal path thru the connection and reduce the volume of material for the electrons to bounce around in. They don't look very sexy though.

(Quote) I could use a larger amp, But I still want to have it inside the speaker enclosure and a Class D amp would produce less heat inside the box. I was thinking about using one of the mono ICE amp boards from PE because they have the amp and powe…

(Quote) Scan Speak unfortunately doesn’t offer a 4 ohm version of the 22W/8857T-00. I sent a massage to them to see if this was something they would offer in the future. They do offer the 10” Revelator aluminum cone in 4 and 8 ohms. Shawn

(Quote) I had contacted Wavecor a few weeks ago to see if they had burn in TS parameters for that driver. They responded back that they updated the spec sheet on their website. After burn in; FS = 31, Qts = 0.37. I wish this driver had a stiffer con…
