What did I say about the SB Acoustics 4" woofer getting 1mH and 10uF? Seems I was right...

Not too impressive IMO. That 6kHz woofer resonance should be addressed.

fakeout you are new and interested, I can tell. Frankly if you want a great speaker that goes loud without effort, 3-way is the way to go.
3-Way Classic

But for a newbie, a nice small 9L reflex 2-way is a good start.
SEAS CURV

This is not a million miles away from the splendid Spendor A9 in drivers. Ought to be very good, though I would again address the Cone Breakup region around 5kHz with an added 0.82uF +33 ohms tank across the 1.2mH bass coil.

Cabinets are discussed here, one of my better posts IMO, but don't worry about details too much. A box is largely a box.
Interesting read I found on Lossy Cabinet designs by Harbeth

Well, I mean some Seas, Scan-Speak and SB Acoustics woofers or mid-woofers are around $50 to $75 for the lower priced models so I was thinking along those lines. I still have at least a couple of months to decide but now I'm kind of contemplating buyout speakers. I think I'm going to take a break from the questions for now (to ponder and reflect lol).

Well, maybe one more question before I take a break from questions. As a rule, does the quality level with Peerless go up with the model numbers like 830874 is superior to 830860 or is it all over the map?

Do yourself a big favor. Mandolin Speaker Kit / Pr

Crossovers already built. Great drivers, great designer, great price.

Build the cabinets or buy pre-built 15 liter cabs.

no, no number/quality relation. In this case just a difference of 1 1/2 inch.
The smaller driver is used in the StartAirKit 3R, together with a vifa tweeter. Fabulous sound (esp. for the price) But also regardless of the price.

I would personally favor a Gravesen design. Especially the 5 inch minis. you can always upgrade, using the same cabinet. But the SAKs are half the price and are probably only slightly less well-sounding, definitely not half as good.

OK, I find the information in the last couple of posts interesting but what do you think of this: Speakerbuilder Pro 2.0=

What is the SC4 option there anyway under the bass reflex menu?

I am not sure what it is. Software for simulating speaker design? I have no experience with such things. Not sure what to think, but established developers are not fond of modeling xo's per internet software by just entering driver parameters and so. stick to a design if u have no experience, no measuring gear and want quick succes.

Troels also has a peerless/vifa mini, so to say a step up of my SAKs. He is very fond of peerless midbass drivers and vifa tweeters, which i can understand. Very nice quality of midrepresentation, and excellent finishquality. (even the cheap drivers)

lol, I finally found what I think I might like. A kit and a design for 4.7 liter cabinets with brand name drivers. The Sopranos by Jeff Bagby.
Sopranos (Pair)

Of course, by the time I get money in May to buy them they may be sold out. Haha, whatever I guess. I wish it came with a birch plywood flat pack though with the driver cut outs already done. A couple of comments I like about these speakers is they can be used in different placements and Jeff Bagby said they sound realistic.

That's a happy choice. Jeff Bagby is one of my favourite designers.

The Sopranos are TINY so don't expect huge bass, but they will doubtless deliver good midrange if you use them in a small room. SB Acoustics make great drivers affordable. Vented bass has always done the business for me.

The issue with two-ways is they don't go loud comfortably. Various reasons for that and 3-ways or series MTM's (it's a simple conversion) are better. But you will have a good time with these. Go for it.

SC4 is referring to bass reflex tuning at the bottom end. Not a big deal.
