Leave the ports alone, add a proper sub to strengthen the bottom end.

 

The bottom end isn't bad (especially compared to my La Scalas) but another 3-5 db on the low end would be nice if they're "free for the taking"

[Chorus 1 Questions]

I did some measurements today: The factory opening is 4 & 1/16. It is 13 & 1/4 inches from the INSIDE edge of the holes in the motorboard to the back wall. My crossovers were already upgraded when I got them (sonicaps) & are mounted in the factory location (on the inside the speaker terminal plate) so port length won't be an issue.

Just so you know (not picking on you most folks just don't know this) the air in a reflex vent will move 1.5 time the total vent length in and out of the vent so looking at your posted photo your vents are already too close to the rear wall of the cabinet for ideal non constricted air flow. Most vents are do don't have a heart attack but just know they are not working as well as they could.

 

So If I end up using a 7" total length tube/vent, would 4" away from the back wall be enough? 

(Someone who was an experienced speakerbuilder did some calcs & said a 7" vent would be ideal in a Chorus 1)

[Kinter 2020a opinions (tripath chip)]

Anyone here tried this Kinter everyone seems to be raving about hooked up to a pair of old-school Klipsch speakers?

It's only 32.00 on Amazon right now. If nothing else, it would be cool to say this tiny thing is all that's pushing my_________ (La Scalas, K-Horn, Heresy, etc.)

I'm tempted to buy one for my office & do just that. If I do, I want to buy a cd/dvd player with a small footprint so the whole rig sits on top of the speaker 😁

They do not come with the flared round edge port but, was going to suggest some to doll it up when finishing project. Thanks for the description and reminder. A flare that was attached to whatever material would be cool looking in black and maybe more solid to finally seal holes at port holes. Of course, grilles may be used.

 

Below is a pic of a Scotch mailing tube, which is the closest thing I've found that seems like it has "possibilities". I will probably try Moray's rolled paper idea 1st, then try to find this Scotch tube as a single at a reasonable price, which is easier said than done, most places want you to buy a case!  (a mailing tube would hopefully be sturdy enough to hold up long term)

 

And, I didn't buy the whole 4" tube from parts express, only the flared end. (it was CLOSE, but slightly too big)  I may try to put the flare on the inside end to cut down on turbulence, especially if it fits snug on whatever tube I end up using.

why don't you try some poster board (heavy craft paper) and see what you think of the mod before you go crazy searching for parts that fit?

 

Good advice, (slow down) The crossovers & diaphragms were done when I got em, so I was wanting to finish off the job :-)

[Chorus 1 Questions]

Been reading/learning alot, now my 1st post is a speaker mod question 😃

 

I have a pair of mint Oak Chorus 1's with Crites crossovers & titanium diaphragms. Chorus 1's have 2 front ports & no rear passive. I've seen an older thread online where someone put in 7" long tubes where the two factory "ports" (really just 2 holes thru the mdf) are to increase/lower the bass freq response.

 

Anyone here ever done that? If so, what fit? I ordered a 4" port from speaker express, but the 4" is the tube Internal diameter, not outer, so it didn't fit...Also went by my local carpet dealer, same problem, outer diameter is too big. & btw I don't want to enlarge/recut the factory holes. Ideas?
