Thumbs up cheap fullrange speaker dy1026u in Ikea-box

Hi all, I like to show you my last speakerprojekt, built in oct. 2009. I use a very cheap speaker, the SENON/ROCKWOOD dy1026u and Im supriced that this one sound much better than many other more expensive speakers. In this 10" dimension I try also: Beyma 10AGN, Ciare CH250, 25-250 5248 U 35 Saba 10 and an old unknown Wigo. I try many more speakers: Fostex 206E, Alpair 10 for exsample and many old vintage speaker, also.

The cheap dy1026u won this race! Now, over one year.

Click the image to open in full size.

The box is a case from Ikea IVAR-system: IKEA | Regalsysteme | IVAR System | IVAR | Kasten

25 in germany, $40 in USA (in germany its cheaper, about $8)

the baffle is made of 13 mm/0.51 inch special plywood in germany we say: "Siebdruckplatte"
the position of the spaeker was simulated with "edge" from Tolvan

The Baffle is decoupled with felt.

The box is vented by the gripholes; 61.9 heart

the bottom of the IKEA-Box resonate... If you mean this must be terrible, you have to hear it. I built an other extreme 90 litre bowl (low resonate).

The deep frequenz is much clearer, but the Ikea-Box sounds more real, up to middle sound level. High Power level is to much, than the bowl will be better.

Later I added a protective grid. of cause we have wild animals

My speakers are powered by an KT88SE Amp, ES AUDIO MEILER PE.

Nice greatings, Hatti

I buy another speaker on ebay and get this dy1026u.

Maybe later, Ill try the 12" dy1256u, also.

Whats the best international use?

240 liter = 54.4850 gallone(dry,US)

= 240 000.0000 kubikzentimeter
= 0.2400 kubikmeter
= 14 645.6986 kubikzoll
= 14 645.6986 kubikinch
= 0.3139 kubikyard
= 8.4755 kubikfu
= 240 000.0000 milliliter
= 63.4013 gallone(liquid,US)
= 52.7926 gallone(imperiale)
= 253.6998 quart(US)
= 211.1747 quart(imperiale)
= 422.3411 pint(imperiale)
= 507.2108 pint(liquid,US)
= 435.8802 pint(dry,US)
= 2.0761 barrels

Thanks for sharing, Hatti.
What do you think of the reason the ball speaker sounds worse than old-fashioned wood box?
Does it mean the wooden panel singing just more pleasant to the ear?

Hi,

sorry Im not here, so often.

I have a new room for audio and now I hear with the bowlspeaker.

Click the image to open in full size.

In germany you can buy this speaker by hth :HIGH-TECH-HIFI

scroll down and you find the speaker.

For my ears I think this speakers are better than the most Fostex I know. Last one I can hear was the 206e and I dont like it.

The 1026u runs without any filter.

nice greatings, Hatti

Thanks for posting that box Hatti! I've wanted to do something in an IKEA box for a long time, but we haven't lived near an IKEA for a few years. One just opened in Denver, and I thought about stopping when I was nearby for RMAF. You can bet I will next time I have the chance! How strong is that box? Have you been using it for awhile?
