Re: Chokes for MoFo

Revised quote for upgraded core: £36 ea + vat. Less 15% if we can get 5 pairs.

Re: Chokes for MoFo

From what I’ve read 100mH should be more than adequate, but I’m certainly no expert. Following Nick’s helpful comments I’ve just spoken to them about the core. He had assumed it was for a PS and the quote was for a standard steel core. They also make audio output transformers and for those they use ...

Re: Chokes for MoFo

Nick, yeah as ever, pick your poison. Everybody seems to love their MoFo though so I guess that tells me what I need to know.

Ed, great lets see if we get any more takers.

Re: Chokes for MoFo

Good question Nick, I will ask them. Is there anything else I should be wary of? I just gave them the specs I mention above.

Chokes for MoFo

I have had quote from a local company to make a pair of custom chokes with the following specs: 100mH, 3.5A and 0.7 ohm DCR. The price is £36 ea inc VAT which is a lot cheaper than an equivalent Hammond. I’m planning a Big MoFo biased at c.3A. (That winter fuel supplement will come in handy.) There ...

Re: PERSPEX QUASAR ver 2.0 prototype build

Pease enlighten me: I presume the C2C distance between the Lowther and the woofer is not a problem because the crossover is low enough to allow for it without creating adverse lobing effects ? But what is the advantage of having the woofer so low down? Does it minimise floor bounce ?

Re: PERSPEX QUASAR ver 2.0 prototype build

No, just came across a reference to them and having looked at the FB page I thought they would be worth putting on the radar. Looks like there is going to be an 8” full ranger as well as the 15” LF driver.

Re: PERSPEX QUASAR ver 2.0 prototype build

2 monoblocks and a pre-amp :wink: Maybe they are for people who value exclusivity and snob value over sound quality per se ? :) Surely not ! In my experience the majority of “audiophiles” believe that high level sound quality is commensurate with high prices and vice versa. There are a lot of credu...

Given your pursuit of a bass solution I thought you might be interested in the speaker that XRK is working on ATM:

XRK is a one man industry and is clearly a pretty smart guy.
