Re: Beyma CP21F match for Beyma TPL150H

I think John is planning on making his own version of the sl600 dipole bass unit .... if I've read him correctly of course !

Re: Beyma CP21F match for Beyma TPL150H

Fair point gents re regarding a peaky response.. But that to me is very different to what I would term 'control' of a bass driver.

In John's case a 1st order may or may not be right.. But he'll learn alot whilst finding out.

Re: Beyma CP21F match for Beyma TPL150H

Good luck with 1st order. Not heard any speaker yet that uses 1st order XO and had proper control of the bass drivers. I do agree that the Eminence Beta is probably the weak link in John's line up, but probably quite good enough for starters. But please do explain the link between 'control' and 2nd...

would it be a sensible move to purchase a adjustable virtual xover box, to get the initial usage of the Open Baffle Speaker Build functioning ?
That sounds a good idea and easier than me adding / removing wire from inductors

Re: Beyma CP21F match for Beyma TPL150H

Just looked up the 12P80ND's, must say I'm very impressed with the specs for a mid driver, a BL of 23, a nice flat output between 200 Hz to 3khz if the specs are to be believed.
Should be a good match with the beyma.

Re: Beyma CP21F match for Beyma TPL150H

I have no experience of those tweeters. but a few years ago I bought some bullet tweeters .. They cost a bit more than those, but after a few weeks listening they still had a coarse sound.
one of them is in my daughter's bass rig now, and sounds good enough
As ever you take a chance..

Re: Remember These?

Interesting. My understanding of NFB is that it relies on a constant180° phase shift, so if the DUT is not phase linear across the working bandwidth (which pretty much no power amp is), distortion will be introduced.... Phase linear amps are very specialised and expensive... Morgan agreed when I ha...

Re: Dynatron HFC 52 with L78 TT

It's a nice cartridge my view, I have a nos g800 and g800e. I also have the p77 and a whole raft of similar era carts

To me it sounds like a shure 44 providing the needle is ok and genuine. Plenty of life in the sound.
I prefer it to shure my shure m75's

Re: Tubes sound better??

I think this item highlights the fact that we're not all chasing the same thing...... I hadn't realised that Steve was so impressed with my VA40, which has now been in the studio setup for nearly 20 years. It was a revelation to me that it was the same output as my 5 watt latfet that I brought to O...

Re: Something stirs in the Undergrowth

OK yes. I was definitely adapting to less treble. However there is a return of the 'crud' I could hear on vocals, as if there is dirt on the stylus I may be off track here Mark but the fx120 are likely to struggle to reproduce the vocal fundamental? My lowthers only came into their own with some fe...

Re: Something stirs in the Undergrowth

Here's some interesting data. I've wondered for a while why it's harder to get Male vocals to sound right compared to Female. https://erikbern.com/2017/02/01/language-pitch.html The male vocal pattern for speech, at least , has more energy over a broader spectrum, than female speakers. Maybe this m...

Re: Tubes sound better??

Steve, It's been my experience that large solid-state amps are the go-to for dynamics. I remember the meet-up at Steve C's where the Crown amp (it came to Owston, too, but not sure if you'll remember it specifically) was happy with large dynamic swings that the valve amps couldn't quite match. I pl...

Re: Tubes sound better??

I'm just in the planning stage of building a few sets to try different valve combinations. The pp3521 that I got off Paul a few years ago need an airing and the da100s need listening to... I've read they sound the same as as my vt25s from 10 years ago.. sort of putting me off. In the meantime I've e...

Tubes sound better??

I had a read through this, nothing new really but some interesting points made... and just when I've bought another solid state amp?
