Help to beginner with 13L 2-way budget speaker

[PKI]

Hi folks, I am really would like to make a relatively cheap book shelf speakers. I found cabs from Infinity RS 2000 speakers and was thinking that it is a good point to start.
The cabs are ~12-13L and outer measurements are: (HWD)14 1/4x9x7 1/4.
The hole is a bit big, but I will take care of it, by routing a plug out of 3/4 mdf.
I was looking for drivers heaving in mind like ~$200 budget.
I've been reading a lot so my head is pretty dizzy now
Here are my thoughts:
Woofer candidates: Dayton RS150 mostly new RS150P, some 6-1/2 peerless (so many of them) and Seas CA15RLY (H1216)
Tweeters: Completely lost :-( Need your suggestions... More CAT308 nice, but pricey, same with SEAS 27TDC, 22TAF/G(this one a bit cheaper but out of stock).
Other options: Vifa's, Dayton, SB acoustic... Please help!

About woofers: Dayton RS looks like kinda nice, but I was reading about a cone break up and need complicated filtering... So if you cross it at 2-2.5k do you still need all these filters? What about their new RS paper series, looks a bit smoother for me, should I try it maybe?

So what do you think, is it worth trying to use cheap driver, or crossovers will be so much more complicated than the total will be the same as using Seas CA15RLY and some Seas tweeter?
Would appreciate any directions!

I'd probably go for the Seas CA15RLY because it has a nice, smooth roll-off. You don't want drivers that are difficult to use when you're a beginner.
I think all the Seas tweeters are good, so you I think pretty much anything you choose would be ok. I'd probably go for a 1" tweeter, just to give you more crossover options. The Seas 27TBFC/G is supposed to be very good according to zaphaudio, so would be worth considering.

How are you going to design the crossover? Have you got measuring gear? Software?

I'm really enjoying the SB29's, a bit pricy but easy to work with and a popular tweeter.

The Madisound Speaker Store

Also been looking at this "new" mid driver - the PE page doesn't match the specs on the .pdf link though :-/

Unless specs are wrong RS159 might better suit cabinet volume. RS180P ~20L~ RS150's ~12L~

This may sound a bit off the wall, but I get interested in some quite retro high efficiency designs rthese days. Cloth surround Eminence bass and cone tweeters!

These might be good together in your cabinet:

Speaker Detail | Eminence Speaker
Phenolic Ring Tweeter 8 Ohm | 270-252

Speakers like this have a terrific clear sound if done right. I'd be looking at a 2.2mH coil and 5.6uF cap on the bass, and a third order 4.7uF/0.2mH/6.8uF on the tweeter. Why follow the herd!

The hole is a bit big, but I will take care of it, by routing a plug out of 3/4 mdf.

If you are able to do that, you'd probably build a reputable design with a new cabinet. The box is usually the weakest part of a cheap commercial product.
There is plenty of good designs for a bookshelf speaker.

Thanks guys! So I am choosing mostly between Peerless NOMEX 830875 and RS150P. It looks like they both have some cone breakups at their high end, but Peerless looks a bit smother. Am I right? Tweeters, Id like to stay under $50. These are not going to be my main speakers, they are planned to be TV-computer ones(if end up to sound good , however I'd like to get the best I can of course

 

[ODougbo]

I'd jump on the sale price

[PKI]

Thanks! But in yiur simulations peerless has a bigger volume. What If you increase one for RS?

 

[ODougbo]

The Peerless sim/box is 14 liter - it was the WinISd default.

 

[ODougbo]

Peerless is smoother?

 

[PKI]

So concluding, peerless is giving more bass, but rs150p is smother?

Hi folks, I am really would like to make a relatively

RS 2000 speakers and was thinking that it is a good

You're on a budget, right ? So buy those ones and
be happy with them:

Peerless SDS-160F25PR01-08 6-1/2" Paper Cone Woofer Speaker | 264-1146

a Dynaudio wanna be:

Dayton Audio DC28F-8 1-1/8" Silk Dome Tweeter | 275-070

Check this out too:
Zaph|Audio

Ask Greebster about Peerless SDS 160 quality features.
He is having a build in progress as we speak. He will know
for sure.

You'll get more powerfull bass performance with this one.

 

[ODougbo]

From what we can see, yes.

Maaaaaan I must be missing something. I'm pretty sure I have or had an understanding of vas but those cabinet volume suggestions are kind of losing me. The ones they suggest for the Peerless Nomex 830875 seem realistic but the ones they give for Dayton Audio RS180P on PE page seem way too small.

Requires a small box ~0.33'² for BR, low end extension is not very good, -3dB @46. Done as a MLTL can do 40

An externally hosted image should be here but it was not working when we last tested it.

Hi,

If you can't design x/o's discussing drivers is pointless.
The above is good value and very hard to beat for VFM.
In simple terms just build it sealed with your boxes.

If you want cheap and cheerful you'd be hard pushed
to find anything with such good x/o's near the price.

rgds, sreten.

 

[PKI]

I don't know, but I didn't know how to walk either ;-)

 

[Greebster]

Peerless is smoother?

Don't trust manufactures specs, so I measure them, you should too

 

[PKI]

Are these with no filter? So how do you like these drivers, do you know how they compare to 830657? They are look similar on paper. Apart from some parameters of course
