Trying to keep below $100 each. So more woofers to buy and try in the near future. That's it for now. Stay tuned.
please post the results/pictures, will be waiting...

Default Manzanita OB

Hello John,
I have seen this thread now and have been reading about the lifelike and lively sound of your manzanitas in various shows. Can you recommend various requirements for a floor standing OB?

Thank you for your interest in the Manzanita OB.

As for a floor standing OB, there are several considerations to be made before a cost effective, viable design should be undertaken. Many potentially good designs are possible.

I suspect you have something in mind. One major consideration is driver availability. Don't want to make recommendations based around drivers that you may not have access to.

Could you share your priorities with us? Cost range, performance goals, anything unusual you may have to work around, so on. And what driver brands you have reasonable access to.

Looking forward to your reply.


John

I know this is not directed to me, but like to respond. I have access to usual speaker web sites in US. PE, madisound etc.

I like the "cost-effective" solution. I am mainly into 2 speaker traditional music, usually with flac file on PC with a DAC (cheap USB soundcard). I enjoy popular vocal/small ensemble jazz, no rock/metal... Do not need super bass at all. Also like to use my 50W/ch high power D-amp, in a small room.

thanks,

The Manzanita with the the 3" FR driver will do that nicely. John should have a refined crossover for it soon.

Hello John,
I will have to source everything including drivers and xover components from abroad,my main priority is emotional,and delicate music with the lifelike presence of the musicians in the room.Even if i have to spend more for this i can spend more also.

Would this be the proper vifa driver for the updated manzanita?

Vifa TC9FD18-08, 3.5" Full Range: Madisound Speaker Store

I would like to get the drivers and begin making dust for this project.

I built the speakers according to the first few posts i.e. crossover from post #3

The 25ohm resistor is way off the mark, luckily I bought 10 off them, so have doubled it up to produce 12.5ohm as suggested by a few posts.

The sound is still sour however.

3 x 25ohm in parallel sounds a little better (i.e. 8.3ohm), but I could spend weeks trying different combinations. I'm guessing somewhere nearer 5ohm is about right?

Anyone want to offer me some values to try?
