Re: Boombox

Has anybody here ever built a speaker with left and right mid bass sharing the same backwave enclosure space ? Like some little boombox and Bluetooth speakers do. No. But my bass cab for low bass (cross over at 70Hz) does. In fact left and right low bass share the same speaker cone! :-D (Separate v...

Re: Turn up the treble

I like my porridge just right. I like clarity and separation but not distortion. I tend to agree with this. When I'm tweaking my own speaker builds, getting the tweeter attenuation absolutely goldilocks is a vital and lengthy (weeks or months) process. I think I've got it right and then I listen to...

When the time comes I'll be getting my head round the different types of crossover components. EG do bipolar capacitors have large mood swings? :obscene-hanged:
Not if the system is powered by lithium batteries.

My robot friend always wondered why he ran on DC when the rest of family ran on AC.
Until one day he found out he was adapted.

Re: 4 way Frankenstein high efficiency speakers

BTW re measurements... It's weird, as I'm sure will come to as surprise on this 'ere bored... These are they for my system's bass...first is measured with the mic where my ears are, the second is where my hand rests on the arm of the sofa...so only about a 50cm difference in position. Exactly the s...

Re: Thought provoking article

I don't think asking for compressed and uncompressed versions is realistic. Take this example, I want the uncompressed version but it is likely that most of my listening will be in a car where the compressed version would be the better option. It's only unrealistic because of the complete pig-heade...

Re: 4 way Frankenstein high efficiency speakers

As far as bass is concerned, and in my very limited experience, size matters a lot up to 12 inches and then there's diminishing returns through 15 and 18 inches. Also as driver size increases I have found that cabinet rigidity / bracing becomes more of an issue; so its not a free lunch. Whether that...
