Hi all Audio Circle members.

I am really interested in building
(This time, as per original specs.
No deviation, no liberties...)
a pair of enclosures for the Dayton PS220-8 extended range driver.

Correct me if I am wrong,
but I read somewhere on the Internet that the ideal enclosure
for the PS-220-8 is either a TL or TQWTL,
not a bass reflex ?

Can someone help me find plan(s) for the ideal enclosure.
(My Vietnamese cabinet maker is on standby.)
I have already an estimate of 275 USD/pair for the enclosures.

In addition, I think the PS220-8 would benefit from a notch
or comb filter to flatten the peak arounf 2KHz.

I would need as well information on that.

Please do not send all your recommendations at the same time
to overload and block my server. (LOL)

Hi all Audio Circle members.

I am surprised that no one has stepped forward to comment my post and/or to help me with advices and/or to share their experience with me.

In the past, some of you were always very quick to criticize my builds.
Is it because you don’t believe that I will build this enclosure as per specs?

Well, this time, I will.

My wife is financing this build and I will pay her back with S…

Services, some of you were thinking dirty…

Anxiously awaiting your advices.

Please hurry up, before my wife comes back to her senses
and cancel the loan.

Not a lot of plans floating about for this driver. I had the chance to hear this one and was more than pleased.

Hope this helps.

Hi ejfud and all Audio Circle members.

Thanks for your your link, it will help me later on,
however, for now I will keep looking.

This cabinet is quite simple to build,
but I will leave the built to my cabinet maker,
of course, if I decide to go with that plan.

I will also build his suggested cross over,
which is not what it should be called,
it more like a notch filter.

Today I did some listening of my Audio Nirvana standard 8" driver
in an open baffle dipole
and it really has a peak in the 2K region,
which make it, up to a certain point,
unpleasant to listen,
even if full range drivers have something special going on for them.

Last week, before doing intensive research on the Internet,
I was not sure with which driver I should go.
(Tang Band W8-1772, SEAS FA22RC2, Audio Nirvana Super CF 8",
Fostex FE206En, Hemptone FR8 and Mark Audio 12P)
The Dayton price is reasonable, well built, nice looking,
it can be purchase from Parts Express
and it has very good reviews/testimonies from actual users.
 
Thanks again,
I hope some more Audio Circle members will imitate you.

These drivers are on sale this week at PE.. 95 dollars each.

Contact Bob Brines:  http://brinesacoustics.com/

I commissioned the first pair of T18-F200 TL speakers (the photo on his website is my speakers).  Bob is easy to work with, is handy with the MathCad modeling, does good woodwork, and offers very fair pricing.  I fronted him $25 to start the design.  Bob even built a test mule to check out any buildability issues before doing my cabinets.  He also offers just plans, pre-cut panel kits, and might still do assembled/un-finished cabinets if you ask nice.

Hi jparkhur and all Audio Circle members.

Thanks for the info, however,
I browse on Parts Express website several times a month.

I saw their special price on the Dayton PS220-8.

Hi JLM and all Audio Circle members.

Thanks for the link.

I might do business with him, but only for the drawings,
because sending, even only a flat pack, to Vietnam, is expensive.

Today I got a price form my cabinet maker for something similar
to what Bob can offer
and here it's only 125 USD/pair complete with grill.

My only problem would be the fiberglass stuffing,
that's something extremely difficult to find in Vietnam.

I will contact Bob and see if he can recommend something other
than the fiberglass.

Thanks again.

Fiberglass should be really cheap to ship.  (Thought you were moving to Canada.)  So maybe for $50 he'd design and sell you the plans (done right).  Bob can also advise to the suitability of the Dayton.

BTW lamb's wool is the classic/vintage standard speaker stuffing.  Probably cost a lot more to ship sheep to Vietnam.

Polyester fiberfill would probably be preferable to fiberglass to at least avoid undesireable glass fiber particles exiting through a port or vent.

I prefer the Big Vented Reflex type over the TQWT type. Dave Dlugos (planet10) can guide you about getting a BVR box designed for your driver. They may already have one, since that is a popular driver.

You could design your own simple straight TQWT with Martin King's simulation software. There are only a few parameters, but unfortunately speaker design is never as easy as it should be...   Brines uses this software to optimize his designs, and has a lot of experience.

Hi richidoo and all Audio Circle members.
(Strange name... What does it mean ?)

Thanks for your advice.

I might use Brines to help me in my design for the Dayton PS22o-8.

Hi srb and all Audio Circle members.

Don't know why, I'm always thinking about fiberglass,
(Maybe because Fiberglass Canada was my customer
when I was still living in Canada)
but I hate to work with that product.

I remembers insulating my basement with it
and even with all the precautions I took,
I was still scratching myself all evening.
(Well, I exaggerate a little...)

This morning I saw in our warehouse here in Vietnam,
something that look like fiberfill
and I asked my wife if it was easily available here in Vietnam
and she told me yes, therefore one day,
I will go with her and see if it's what I need and buy it,
because I am sure here it will be super inexpensive.

Well, one problem solve, a zillion more to solve.

Hi JLM and all Audio Circle members.

Fiberglass might be lightweight depending on how much you get shipped,
but it's bulky and it could be expensive.

I did move back to my home country Canada,
but over there it did not worked as expected,
therefore I came back to Vietnam,
where cost of living is 1/10th of what it is in Canada.

My wife is renovating our first house
(We have two)
and we will rent it (1,500 USD/month.) and one day,
I will be able to retire without any money problems.

Back to the topic.

I found some polyfill or fiberfill that won't cost a fortune,
I will be using  that.

When ready,
I will contact Bob to see if he can sell me a plan of something
that will work with the Dayton PS220-8.

Thanks.

For TL the best driver I aware is the Morel (and maybe the Shabani) as used at the Renaissance TL speakers:

The drivers that you are referencing are woofers, but this topic is about full-range/extended-range drivers in a TL or TQWTL enclosure.

OK, Sorry.
Supravox site had some TQWT plans obviously modeled to its drivers, not to Dayton.:
http://www.supravox.fr/anglais/kits.htm#Tqwt

I dont like these plans, they sport a front open throat, and I prefer a lateral open to form a central soundstage, a non insignificant feature, as in this model:

Just found this simple plans to the Supravox 215 with Lateral Open:
