W8-2145 lying around - building something fun with them? desktop use?

[irishrOy]

I have a pair of W8 2145 lying around and wonder what to do with them.

Open baffle is out of the question and I already have a pair of BIBs doing their job wonderfully as "allround speakers" with W8 1772's in them.
Thanks to @Scottmoose I also already have a pair of desktop TL speakers. So all my audio-needs are taken care of.

Just for the fun of it, I thought about maybe building "very small" desktop bass-reflex speakers so I could have the 8" speakers blasting into my face more or less directly.
What else could bedone?

Why not try Tang Band’s simple suggested design for it.

Posted response in the above cabinet needs baffle step comp circuit for sure or it will sound bright and fatiguing. Use a 1mH and 6.8ohm in parallel to start and adjust R to taste.

Tangbands suggested Eighty-one liters of enclosure can be tweaked a little to extend the bottom end a bit. I got a -3.01 Db @ 31.25 hertz for a 125 liter size...tuned to 34.8 hertz...100 mm by 200 mm Port, 279 mm long.

Yes, that rising response really should be addressed, of course a 31 band EQ could null this out & fine tune evrything, but I figure a more permanent integral approach should be tried.

81 liters = 2.86 cu ft. 12" × 15" × 27.5" is just over that. Have the drivers and going to give it a try using a slot port feeding and angled horn type opening at the foot of the box. Will try that simple filter to tip down the upper end as well.

... and the 180 Hz enclosure length notch in tang band's proposal can probably be evened out using a mass loaded TL with driver and port offset from (stuffed) TL ends.

Have never looked closely at TL boxes..guess it's time.

Interesting, the TL methodology seems almost exclusively focused on bass response. How much better is a TL enclosure than a well designed bass reflex one?

A lot better.

I have sold my W8 2145 since I didn't know what to do and I already have a pretty good setup with W8 1772s in BIB-speakers.

However: definde "better"? To me, given roughly the same volume of the enclosure, TL-speakers sound more warm, full and resonant. The bass might not be as punchy as it migth be with a BR, however it's much more precise and thus, also punchy in its own way.

I compared some TLs and BRs and in comparison, the BR's bass sounded a little "mushy" and not as well defined as the bass from a TL.

But that's just me. Different taste and all

Was thinking of stand up bass and cello, plucky and clear. The quarter wave thing is interesting, in my case a 40hz tune might be best.
