You must be referring to Tapped Horn paper not Labhorn paper.

Danley's Labhorn paper compares his Labhorn stack to an idealised vented cabinet stack.

The perception of loud however is a different story as the 18 will compress and breakup way before the 15 TH resulting in higher frequency harmonics and distortions making it "sound louder" even though the TH is busy rearranging your heart rate. This is real world experience..
Do you have real world experience with this? Meyer doesn't make a single 18 do they?

You made the claim that a diy 15 TH is way better sounding than a pro vented sub. Well given the same volume box and SAME % of distortion... its NOT. The 700Hp wins handily on low frequency extension and Max SPL...

Price, weight, efficiency, simplicity even all that I give you... DIY TH wins in spades. You don't need to argue there... but rhetoric that a DIY TH 15 (that runs out of excursion with <250w) is besting a linear, low distortion, low power compression 2x18 pro sub with fancy sense electronic trickery and greater PE, sound wise is just wrong. And that's singly not a truckload.

Ah I see. You are right sir! Any commercial double 18 properly powered by the manufacturers suggested and supplied amplifiers, and processing gear is going to BE BETTER than any diy cabinet ever made in the world.
Since Danley is a DIYer and so was John Meyer we can eliminate them as well.
Which commercial speaker company do you work for or represent whose equipment we should be buying, sir?

I've never seen a single Meyer but I've played with a single loaded and resealed 650-p. I have seen and played with the processors (insides) as well as the old Meyer modified Jbl 2" drivers. Cool stuff. I work with Meyer 650's and UPa's quite often and occasionally with an Msl4 rig. I have recieved compliments from Meyer owners... Like the Kravits Center people and other major Meyer players in the area. I was going for the Meyer sound as my holy grail when I built both of my pa's.
If I had 80 thousand dollars, I'd have a Meyer system or a Danley.


I'll let you know how my Molly Hachet show goes next month.

You're not making your point. Danley showed the world that he could blow-away stacks of dual 18's with six LabSub horns. That their port nonlinearity and power compression were their downfall.

Preliminary indications show that a THAM15 should be producable on a single sheet, but the definitive result remains until the build is finalized.

This information was given to me from a person who is now preparing to build a pair of THAM15 MKII's that incorporates four refectors in the hornpath, good news initially, and hope they do not change.

Even if that is the case, the difference in size coompared to Jbell's excellent design makes me wonder if they keep up, time will tell.

jbell I really like your plan, I have modified it for my needs.

I'm using 18mm wood and have used a square throat like in the furybox to hopefully reduce excursion at high levels. most of the dimensions have changed to accommodate the thicker wood but luckily doesn't seem to have made much difference to the output.

Its not strictly a single sheet anymore because the baffle is now two pieces but I'm using some spare 12mm wood i have.

These plots are calculated with a Kappa Pro 15lf2, any thought on using this driver? lower xmax but hornresp shows lower excursion.

I'll post plans etc soon but my laptops broken.

Screamer was using a little hyperbole to say that his DIY TH-15 would introduce unheard of level of fidelity to a "pro guy" used to direct radiators. I gave an example of pro woofers that are more far more linear and more extended. (granted they are more SD, displacement and power handling)


I fail to see what relevance a Lab sub stack has to do with a different alignment, used singly or pairs. You know as well as I TD has claimed that large stacks of FLH will trump TH for efficiency.

Hi Hell on wheels,
Have you read Danley's paper on the Labhorn?
Have you compared Labhorn to Tapped Horn?
