I think we know your secret, Simi....I've figured out how to get them sounding great in a living room.. never be sold :
Mine are definitely the Symbiotics since they say it right on the sticker. And I was literally blown right out of the room by them. I have no need or giant speakers in my house, as Alan (abeep) can attest. So maybe I'll pass the good deal along to someone else. If I'm going to do a speaker project, I'd rather do econowaves as I have plenty of drivers to do that.
I am curious to see what Zilch has to say though.
O.K., let me try again:
We can buy A pair of competent modern drivers that WILL get there for the cost of a pair of Altec replacement diaphragms alone, no?
And still have the 808-8As to set on the mantle, or whatever?
We've got 8-Ohm woofers, right?
I believe we recently looked at 808-8A drivers, and determined they do not have tangerine phase plugs in another thread, so they cannot be converted to 802-8G
That means sell them and the N501-8A crossovers and replace with Model 19 components, 802-8G or 902-8B, and Model 19 crossovers.
An improved M19 crossover, Zilch's Z19, can be built from scratch by an intermediate-level DIYer:
Bail.... :yes:
Will they then HF comp to 20 kHz like 802-8G without tangerine phase plugs?
Cool. I've never measured any 902-8A, so there may still be hope. Let's see the GPA curves....Dont forget 902 8A, the best of the lot according to many. a 902 8B does not completely "convert" when you remove the loading cap, and install short screws and felts. There is still one difference, a piece known as the centering ring. In 902 8A, it is perforated, ( as it is in all 802 drivers ) while the 902 8B is not. These perferations vent the dome to the area where the magnet is, and this is said to be the "difference". The GPA 902s are copies of 902 8A.
The Hiraga schematic I've seen adds HF comp similar to what I initially used with Valencia, but in the case of 288, it seems the primary benefit is to mitigate the excess midrange rather than extend the HF response.I also have a set of NOS (except I took them out of the box and used them) 501 8B crossovers. I dont think they are modeled on anything HIrago did, never heard that one. I have seen the schematic he uses, and he uses the 1505 horn and 288 drivers.
Jack of all, master of none.You are an acclaimed polymath. :yes:
I'll be surprised if Damage bails. Typically, when a member posts that a speaker sucks, and I agree, and provide the data supporting that contention, next thing I know, they come back concluding they're the best speakers they've ever heard, now, and they're keeping them.
Third time's a charm, perhaps, but reverse psychology might be viewed as my nefarious modus here.... :scratch2:
