Blue Planet Accoustics Speaker Kits

[Musiccynic]

Has any one had any experience with Blue Planet Accoustics (Lautsprecher Bausätze - Lautsprecher Selbstbau by blue planet acoustic)??

Are their kits considered to be reputable designs or are they just thrown together?

I have been looking at the MarkStart Kit (MarkStart Bausatz - Lautsprecher Selbstbau by blue planet acoustic) or the Pipe 6 (Pipe SiX - Lautsprecher Selbstbau by blue planet acoustic).

Blue Planet has a good rep. Being in Canada i haven't had an opportunity to deal with them thou.

BPA published the XO for the MArk Start in the Mark Audio #6 woofer/#3 tweeter thread.

Darcher in Tas can supply drivers & XO (or XO parts).

This thread ends up being about similar http://www.diyaudio.com/forums/multi-way/143326-kit-australia.html

I've got the MTM cabinets for the MA 6" bass drivers. Need to install everything and devise an XO.

Crossover - Markstart

I have the schematic for the crossover for the Markstart, this looks like an easy and cheap kit for my first attempt.

I have heard most of their kits and know the guys pretty well.

All of their kits are very good. The designer has years of experience and I can assure you none of the speakers are thrown together.

The MarkStart kit is very impressive and an ideal candidate for introducing someone to what is possible in the DIY world.

BTW - they may have completed crossovers for this kit.

Hey Musiccynic, did you ( or anyone else) try these? How did you get on?

 

[Musiccynic]

Hi Simon,

I have not yet purchased a kit, I am was hoping to compare the BPA kit with one to be offered by Creative Sound Solutions - Loudspeakers, Parts and DIY Speaker Kits using the same drivers, but creative are yet to release details of their kit.

I have found a forum where someone has built the bpa markstart kit (MarkStart Kit von Omnes Audio, Projekte der Nutzer / Nachbauten - HIFI-FORUM) , but you will need to translate if you do not read German (Google Translate).

Will post all details when I make the jump.

Hey there,

I'm from Germany and I made good experience with this dealer so far. Contact and customer service is ok, delivery had always been fast (in Germany).

As someone stated before, they are known as experienced developer. The reviews in the "Hifi Forum" on the "Mark Start" kit are positive.

I'm going to order the woofer which is used in this kit.

Regards, Alex

Thanks for the info guys. I guess at that price with Marks reputation its hard to go wrong, but I know how easy it is to mis tune TLs. The translation is great fun, must upgrade my crossover sticks too!

Hi, sorry if I'm resuscitating a old thread, but I've build a markstart earlyer this year and I can say that after a burn in period, I'm very impressed with the results.

The experience with Blue planet acoustics was very positive, shipping costs to Portugal unbeatable (free) packing and delay very good.

The cabinets @ Creative Sound Solutions look like the ones sold by parts express I think Blue Acoustics have a much better range nicer designs anyways but somehow the drivers and parts look better @ Falcon Acoustics | The Leading DIY Speaker Parts and Kit Supplier since 1972 ?

Bob is a PE distrib. If you are in Canada he is the best source for PE boxes.

To be honest I don't like PE very much I ordered a 50W T amp from them some time ago started falling apart started clipping at higher volumes pity because it was nicely built otherwise didn't sound to bad.

Their standardised cabinets are as ugly as sin no finesse at all just mass market stuff - horses for courses as we brits say

 

[planet10]

The rectangualr PE cabinet sare not very good, the curved ones are pretty good as far as MDF cabinets go. The sides are made of 6-pies of MDF and they are braced. The MDF is of lowish quality and the outside finish is fairly fragile.

Yeah I'm not sure why all the cabinet manufactures don't invest a bit more in developing for the DIY Market beats me, that's why I hold some respect with the guy's over in BluePlanet Acoustics Lautsprecher Selbstbau by blue planet acoustic apart from the nice little kits they put together the variety they offer means we have choices and they seem dedicated in bringing new stuff across although still it's all a bit basic. but they are thinking out of the box unlike companies like PE that are simply static with no development going on.

I'm going to try one of their smaller kits see how that pan's out next month it will be my first speaker build but hopefully not the last.

I more favour horn throwers or a semi open design which they have on their site but only a couple, be great if they started doing some weird and wonderful stuff new materials forms and equally focus more on the internal acoustics design as well, they got the basis of a good business but the draw back is they arn't cheap cheap !

Do you know anything about ''Mark Audio'' if their drivers are worth using Markaudio?

Falcon Audio seen to sell better drivers by the look of it for the money Falcon Acoustics | The Leading DIY Speaker Parts and Kit Supplier since 1972

 

[planet10]

I am familiar with Falcon and had a (very) small hand in helping the fellow now running it in its resurrection from the dead.

When i worked hifi in the late 70s i sold a lot of the stuff from the original Falcon... they would really be flying if they could source a modern B139.

They don't do the kind of stuff i personally like but i aplaude what they are doing

In general i like the Mark Audio drivers, my favorites are the A7.3, EL70 and A6.2, the others are pretty good too.

Do you know about the Frugel-Horn Mk3? More or less open source and currently there are independent flat-pak manufacturers in North America (Canada), the UK, Australia, and The Netherlands.

Colin in the UK has done some of my designs and Ben in Oz is ocasionally instaling my treated drivers.

do you have crossover for he open baffle speaker? I'm interested in the design with the Tang Band W8-1808. 450Hz crossover point.

Blue Planet Acoustic Power Trio 15-1772 – Falsche Diagramme in Klang+Ton 1/2015 | Klang+Ton – der Blog

I plan to use similar full ranger, but not W8. maybe a good midbass to 7KHz and a supertweeter.

 

[picowallspeaker]

Talking about the 1772 (TB) there's a strange project with it
(the four passives required for each would cost about as the TB )
Just scroll down a little to find "the Gusspeaker"

...then some others OB projects

 

[perempe20]

I'm interested in open baffles. Blue Planet Acoustic claims 93db. sensitivity. is it possible with 2 Alpha 15A woofers per speaker?
