WOW !! high WAF

[Moondog55]

OK I have an anouncment and I am boasting

It’s my birthday net Wednesday and guess what my fiance bought me for a present?????
A pair of Vifa P13’s to add to the pair I ordered last week, you could have knocked me over with a feather when I opened the box from Speaker Bits and found four (YES 4!!!) drivers inside the box.
Is that high WAF or what??
Now that I have a quad of them my plans may change and I am open to suggestions

something like this would be very good ;-))

except use a Jaycar 10" for bass and a 3-way series x-o.

Something similar to the Blackwood x-o would get you pretty close.

Do not ask the P13 to do bass and mid duties.

coordinate the speaker design with SWMBO !!

Andy HI! the wife to be is laughing her ******* off here.
But that is exceellleent advice (spelling mistakes intentional)

Andy what do you think of the Peerless 830668 woofer
http://www.speakerbits.com/Default.a...upage=150&pi=3
Not to shabby on the graph and its reasonably cheap being made in China and optimised for sealed boxes.

I've had my eye on that one. looked at it more than once, but have not used it yet.
I have had an all Peerless version of Blackwood in mind, but it hasn't happened yet.

I won't tell you what I would be paying for that driver. You really ought to find an ABN and see if you can get 'trade' status with WES, great for prices on Vifa, Scan, Peerless !!!

I only pay $45 for the Jaycar 10"s !!! Not sure what retail price is.

Glad your other liked the reference !

Lynn Olson's Ariel or ME2 with a dedicated sub for each channel?

[Andy G]

OB mids jump all over mids in cabinets of any sort !! (imo)

And if these are mainly for music, I would choose a normal bass driver over a sub any day.

If mainly for HT, there might be a case, but why ask the P13 to go down to 80 or below to meet a sub, when you don't need to.

[Moondog55]

definitely no lower than 120, more probably 150/200, I have that B-139 there, and a Jaycar 10inch carbon fibre woofer.

How about a "Blackwood" clone but front and rear firing woofers small sealed box with first order high pass on the jaycar with the Jaycar firing to the rear

[Andy G]

You have a pair of Jaycar 10" Response carbons???? Lucky boy !!! Put them in vented cabs you will get very, very nice bass !!! The carbons are even better than the polys, which I really like for bass work. Gumby used the 12" carbons.

The B139 is nice for bass too, but I think they require quite a big cab (again iirc). I have a pair in TL cabs, smooth and deep !!

But I would NOT mix bass drivers !!! One or tuther !!!

If you go OB mids, with the U-frame about 75mm deep behind the baffle, your cut off on the mids will be somewhere around 180ish iirc, which is perfect for the P13's, but means you really do have to use a normal old-style woofer, not a sub driver.

Also, the P13 prefers to cross around 2400Hz or a bit below at its top end.. Use a good tweeter (Seas are best value for money), and again you are just about in the optimum x-o region for both.

btw.. did you know we will soon have a new Seas dealer in Australia.... more later.... I'll post his web url when I get it.

SO!? youve finished the :Manhattens" then??
I may have offered to swap the Jaycar for your KEF's

I have a friend here in Reservoir ( Hungarian actually) who makes a great F&R woofer boxes using Jaycar drivers, and using drivers with different parametres seems to work in his front and rear firing units, I haven't built my Tardis yet, still saving and planning for the wedding .
BUT after the wedding ************ maybe I'll get some time to go out to the shed and play
