Building tower speakers

[jmanpc 5,000+ posts]

Well, for lack of a better Christmas idea, I've decided to build my dad some tower speakers to go with his new TV and reciever.

Here's a few drivers I've been looking at for the project:

Subwoofers:

Tang Band W8-1363

Tang Band W8-740C

http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=264-854

Dayton DC-200

http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-310

Dayton QT210

http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-545

Questions: All the drivers I want to use are 8 ohms. However, some of the subwoofer choices are 4 ohms. Do I need to match the impedance?

Midrange:

Dayton Reference 8"

Dayton Reference 7"

Tweeter:

Dayton DC28FS-8

Vifa D27TG

Crossover:

Dayton XO3W

Any other suggestions?

lol it aint just gonna be from me. it's gonna be like a family-to-dad present. I'm just building 'em and pitching in some $$ to the drivers.

Run the subs off of a plate amp mang

You really shouldnt need much power

we've got a 8" yamaha powered sub. it's not much low-end so I figured we'd build some into the towers for some low-end reinforcement.

The xovers are going to be a pain in the *** on them man

You better know your stuff

woot for prefab dayton xovers.

 

[Thieroff 10+ year member]

Haha, they may sound ok at best

all passive Xovers are based on impedance, and all speakers impedances are different, impedance changes with frequency

you'll find with those xovers you'll have dull spots and what not

go to a DIY forum and they can prolly design some xovers there for you for 10-15 bucks

Much, much better idea man

Honestly, my dad isn't a huge home audiophile. He wants something that'll sound 'good'. I'll be off at college, so I won't be bugged by dull spots. Maybe if I get bored enough I can do some xovers. Point being, I'm fine with them sounding okay at best. He's thrilled with his pair of Infinity bookshelf speakers. Anything would be a step up from those.

So how bout them drivers. Any ideas?

I would say the TB 8's should fill out the bottom end just find

which ones? the neos?

7" or 8" midrange? vifa or dayton tweet?

 

[Thieroff 10+ year member]

They're really a sub, nasty little ****ers man

go with a 7in midrange

I'd got with the vifa tweet
