Neat. Can't wait to see it.

I'm certainly not a fan of the ½Boominator either as you can probably tell from previous posts. And while the Boominator is on the large and heavy side it's still a practically possible design. Going to 8" or smaller drivers is simply not possible without sacrificing huge amounts of sensitivity or bass performance or both. It does not matter how expensive an 6½" or 8" you find, they will simply not match even a low cost 10" like the HP-10W or G-1058.

I suggest to try and build it (in the full version) you will not regret it.

Okay. Seems that no one saw my post so i'm just gonna post it again.

Hi.
I'm relatively new to all this. So therefore i have a question i want to ask. I plan on buying one of these 2011 New Version Lepai Class T Tripath TA2020 Amp 20WX2 - eBay (item 290534649380 end time May-15-11 14:30:04 PDT) and connect with two of these which i already have http://6x9carspeakers.org/blaupunkt-...xial-speakers/. But since those speakers aren't very good i plan on buying two of these HIFI KIT ELECTRONIC AB - Högtalarelement HiFi Hembio Billjud/Marin Studio PA/DJ Kablage Tillbehör also. Now my question is if i risk frying the amp if i parallel connect the speakers to the amp since they are different ohms?

Thanks!

Hi Grummegustav,

You probably didn't get an answer because you are posting in someone else's thread. Now to answer your question, yes you will harm your amp if you wire the speakers together in parallel. The amp requires a minimum of 4 ohms. The second link speaker is fine at 8 ohms but the first link which wouldn't open for me is for 6X9 car speakers. Car speakers are almost always 4 ohms so you will drop below the 4 ohms if wired in parallel.

Possibly. Going below 4 ohm isn't recommended with the TA2020 model without proper cooling.

I don't see how, so I ignored it.

States they expect stock again on May 31st, so there's hope. Sign up.
Sent a mail to Unbenanntes Dokument who answered that they'll have the HP-10w on stock late may aswell. Ordered 4, so they better be right

For those interested, I made a betaversion of the half boominator in Sketchup. It's a complete version until someone tells me something is wrong
Also, it is the design I intend to use this year. It's a bit different than the original boominator, but has some of the old features.

Can be found at this link: Half boominator

Thanks to Saturnus with contributing with the original design.

Hello again

I'm pretty confused on what Piezo's to use.. I don't think I have enough time to order the ones from Ebay?

Is there any good Piezo's to order from a Scandinavian/European site?

Basically, you are looking for a replica of the Motorola KSN1005 or the original tweeter itself.

For example this one: https://www.elextra.dk/main.aspx?pag...e&artno=H19399

Or this one: Tweeter højttaler PT-1010 | BN100285 - Elektronik Lavpris ApS

There is also the option of waiting for the bubble tweeters from eBay to come in stock again, but that may take weeks.
