First DIY loudspeaker project for LM3886

[talaerts]

The Viech is cool, cheap and can play damn loud, but it won't have the deep bass you probably crave.

If your budget can be a bit higher, but still reasonable, then the following coaxial project should bring a big smile on your face when rendering metal at concert levels. Your ears will give up before the speaker does:

Strassacker: Speaker - kits - do it yourself

are you going to build the boxes yourself?

what about putting a crossover together?

Yes, a friend of mine is a skilled wood worker, and should give me a hand...

Looks good! The Eminence beta10cxl is rated 250W, can this be driven by a single lm3886? Should I go for adual chip design or something totally different?

crossover building?

[kiske1]

I have some basic knowledge in electronics and know how to use my solderer.... I think (hope) building the crossover section will not be a problem... If I'll encounter problems, I'm here to learn...

I'm a big metal fan (most of the 80s and 90s stuff), and my experience with FR is that heavy metal/thrash/death metal doesn't sound good with FR units, especially the revaling ones. Lot of these recordings are on the thin side, and on FR units that bring out mid-range detail, they tend to sound thin and small. Paper cones with some xmax tend to work better vs metal cones, and bigger cones do metal bigger (music sounds large). Metal music benefits from higher energy in the 80-200 Hz range (maybe actually the range is wider), and I am planning to do a bi-amped FAST (Full Range Mid-Tweet, helper woofers) with XO at 150 Hz. I've played around with bi-amped FAST with XO done through Foobar, and there are definite benefits for metal and techo genres.

i think paper woofers and metal dome tweeters sound better for this type of music (specialy 80´s stuff)

Ok, thank you Metal brothers.. could you please point me out to a project using paper woofers and metal dome tweeters that is viable for a beginner with a money cap (components only) at 200€? For the housing, as said before, there's no problems in building it myself at low cost.

why dont you bid for used JBL speakers (3 way) like LX400,LX600,LX800 ? same price as diy in ebay.it
