I'm forever ordering a few things from Parts Express and then needing something else after it ships. Sound familiar?
Well, I began to accumulate some parts on the "shopping cart" beginning with a 5 Watt 5 Ohm resistor to fix "Ella". Then there were those banana plugs I don't have to have but wanted and some shrink tube, etc and the 4" Pioneer full range speakers LIMITED QUANTITIES for $ 1.25 each!! Shielded!!
So this reminds me that there's a regular item 4 1/2" Pioneer full range that Dickason wrote a design for. I go looking for it and stumble upon the PE chat board. This is at 6:30 this morning. On this board are posts about a DIY get together hosted by PE in Dayton.So I says to myself, "self, you can have the parts today and see some people and hear some speakers" and visit their store and get everything you need. So I'm in the truck by 8:30 and headed out to Parts Express, a 150 mile jaunt.
They have some rooms at a Hampton Inn across the street like a mini MAF. Jim Griffin is there with his line arrays and another manufacturer but the main event is a room where a dozen or so guys show the speakers they've been building all with the same source/amp. Moderated by a fella from Speakerbuilder, Ken Ahearn.
His own design was the hit but so inefficient it clipped the 150 watt amp several times.
This seems a pretty good format to compare speakers, learn about what works and doesn't and still fun.
I didn't hear anything better than what us "horny's" have but it was interesting, nonetheless.
And, best of all, (too bad you weren't there) all the PE merchandise at the store was 25% off!
I'm listening to a pair of the 'buck and a quarter' (less 25%) speakers just sitting naked on top of the old Fisher receiver. Not bad.
Anybody want to take a crack at what to mount them in?:
freq resp 70-15,000
eff 90dB
Re 7.45
Fs 106
F1 81.75
F2 137.25
Zm 50.34
Qms 5.23
Qes .91
Qts .77
L1k .62 mH
I tried boxplot and it recommended a 137 cu ft box!!!!!
I'm thinking a 6X6X30 tall with a 1.25" port just the thickness of the plywood. For surrounds.
Oh yeah, I got the resistor and fixed Ella.
Do I have to say thanks Wayne for getting me started? Thanks, Wayne.
