How do you think a sundown E v4 or v3 15” would go or a SA v2 15” would go in the Tham15 enclosure or do you think the turbo sound nuq118 would go I know that’s a 6th order and the other is a tapped horn but what would work better for outside movie nights and stuff using one of those 2 drivers

Its the original version, there has been claims that it is the loudest one (most cabinet volume). Not sure about the sound quality differences with or without the reflectors.

e15lf seems to be almost identical to RCF L15P540, according to specs.  Thus, I can say it works. Not the best driver for tham but it does give very tight/punchy and detailed bass.

Even more comparsions. Real world listening tests still showing P540 as better choice for Tham15, compared to P200/A.   So now I tested P200/A 8ohm vs. P540, here are the results (Red=P200a):


At 40Hz, P540 is about 3dB louder and overall flatter bass response. 

P200A has a lot bigger VAS (190 vs 100) and much lower FS (33 vs 56) while Qts, BL etc are pretty close.  Maybe this will help choosing the drivers for Tham 15.  It does like low vas high FS drivers according to this.
(I have actually noticed the same with HOG scoop. Low VAS medium FS the best and of course, strong motor).

Now let's test the same drivers in cubo 15...

Yes, I have noticed the same. 

Just punished my tham15 @ 1kW of power, oh my.. it slams hard!  And it has much better cone load compared to cubo. P540 was not happy in cubo (over excursion and flapping etc) but no problems in tham.  Brutal thing being so small but requires careful EQ settings.

Big up for sharing your findings Tonskulus, the forum has become awfully quiet nowadays.

Thumbs Up

Yep. Overall Tham15 is one of the best for my needs. Cubo might be louder but its also bigger and tonal characteristics are not so good to my taste. 
I have designed two ml-tqwt enclosures for 4 and 6" full range drivers and they are amazing.  The openness and good integration of bass frequencies with upper band is so good.

A Speaker will only loosen up based on its environment. If you are swapping a speaker in different boxes on a constant basis, that speaker will break in according to the box that gave the loudspeaker enough room to move freely.

If you are looking for a speaker that offers minuet deviation from it's published TS Parameters look to wards Eminence or the old Made in England Celestion.

B&C, Faital Pro, Electro-voice, Beyma, Fane, in addition to, RCF drivers will offer significant changes on their Parameters once measured in free air based on my experience.

You should also focus on one design and disregard the one(s) that do not meet up to your requirements. If the tham 15 gives you what you are looking for from a tonal standpoint, you do not need to focus on the cubo 15. Get rid of the cubo boxes and build more tham bins. Don't get caught up spending a lot of money on drivers to band aid a box design in which, all in all you really do not like the tone it projects when, you have a next design that satisfies your tonal requirements.

Best Regards,

Yes I do know those things pretty well but you never know how much parameters will shift over time..more or less and this makes some confusion for design progress and simulation. Thats why I measure parameters after break in progress to be used with sim software. 

Anyway I need to look for more 15" drivers to be measured with different cabs like Tham.  15TBX100 seems to be a good candidate, or cheaper alternative 15PS100.

Short video, tham in action, low power but there was good amount of bass!
