yeah, two THT's will cover the bass department lol. that will be a nice setup. a ton of performance per dollar for sure.

lol, that they do... quick question before I hit the "order button" on PE

it lists TWO of the 20uf capacitors and one of the 1.5 capacitors on the spreadsheet on DIYSOUNDGROUP... but the PICTURE seems to show 3 different sized capacitors (unless the picture is just making them out to be different. I just wanted to make sure I was doubling up on the20uf capacitors or whether it was a mistype that hadn't been corrected.. (the one in the middle looks slightly smaller). here's the picture for reference

That photo was originally taken for the Karma-15. Just order the parts that it says to order on the Cheap Thrills page and you'll be good to go.

Hey Erich,

Any updates on the flatpacks for the Cheap Thrills speaker kits?

Thanks in advance,
Mike

Well, I got the cheap thrills hooked up today in my shop being pushed off a single channel of an ep4000 and all I can say is holy hell loud. Had a set of Polk RTA-12's hooked up before these in the same spot and although those speakers still sounded great would reach their limits long before these CT's do. Every time someone listened to them they would always say how clear it sounded.
Its been awhile since I listened to my tempest for music but at first listen they sound quite similar really... I honestly can't say I'd choose one over the other but the CT's were considerably cheaper so I'd likely go with them if size wasn't an issue.

Only issue I have now is that I run out of bass when I start playing the CT's really loud... one 18 isn't enough think I'm going to need 3 more. It never ends....

The CT is the best deal going if you don't mind the size. I have one Cheap Thrill run off a Lepia amp pushing about 10 watts to the speaker. They are really efficient and I can't believe you're running it with the EP4000, I'm guessing you could get by with a lot less power. wink.gif


The designer didn't want any donation on this one, but I really should set something up.

hah, well I'm using a cheap pyle pre/pro amp and the speaker outputs literally fried but the pre-outs still work so I use one channel to run both speakers and then one for a sub currently... Its a bit excessive but even still the amp clip lights were coming on before the speaker was tapping out but it was wayyy to loud in a 4000sqft shop.

I built the boxes with the help of my father in his A/C'ed shop and hooked it up to his little radio to test them and it was quite amazing the sensitivity difference also... 10 on the dial was quite loud with the CT while you could barely hear the speakers that came with it.

Finished the cabinets with the help of a friend who just happens to be a pretty great cabinet guy by trade. I don't suppose this really qualifies as DIY since really the only thing I did was draw the plan in Sketchup for him.



Cabinets are piano black gloss finish on birch.

On to the crossover this week. Doing that myself ( I haven't soldered anything in years).

I am seriously bummed that I missed the Celestion 15 buyout opportunity! I was seriously wanting to do a build with a Seos12/Celestion15/DNA360 for my 4 surrounds! Does anyone know if or when Parts Express will get some more, or if there are any other places that carry them?

the TF1525 appears to be its replacement.

http://celestion.com/product/99/tf1525/

frequency response and impedance sweep look pretty darn close to the buyout driver BS-15300 8ohm.

both are high qts and would probably work quite similarly if that is what you are looking for.

similar sensitivity and roughly the same top end rolloff.

you might ask bill if it is close enough to be a direct replacement.

street price appears to be around $95 or so, but who knows what you might get if you ask for a discount. :-)

Listen. It's All Good.

I wonder if what bill was hearing that he liked so much about that driver is the result of the small coil and therefore low normalized inductance. the impedance sweep doesn't arch up very much at all. almost looks like a more sophisticated motor with shorting rings and such.

Listen. It's All Good.

That might be part of it, I don't know. I also liked the 10" Advent woofer earlier on when used with at QSC waveguide. A characteristic of both the Celestion buyout and the Advent 10" woofer is that they roll off smoothly at the high end without massive breakup peaks to mess with, makes the crossover easy and not needing to be too sharp. That was part of why the CT was so cheap to do, too.

The nice thing about the overall sound of these is how the waveguides and large woofers blend, crossover area isn't noticeable at all. Very clear sound, but unlike most "crystal clear" speaker sounds (which are crystal only in the treble) the sound is as clear in the midrange and upper bass, too. The sound seems to not come from the speaker. TD15 can do that too, of course, and probably the big JBLs, but the price difference between that and the Celestion woofers (particularly the buyout) is a lot.

BTW, I only designed the crossover for the CT. Erich had the concept, did the box and baffle sizing and layout and did all the dusty and heavy work. I wanted him to make it 12cuft so it could play ported to 32Hz! Because I wouldn't be the one who had to carry it....

They are close, but not 100% the same. The Karma-15 was designed with that Celestion woofer before the buyouts came along.

So can the TF1525 be used in the same enclosure and with the same crossover as the CT? I would love to use one of these TF1525's in a Seos-12/DNA360 for use as my surrounds. Heck, I may order some of these just to play with and to sharpen my active crossover skills!

Any hope of a Cheap Thrill with the 15" SOES? Any hypothesis on if that would improve the design or just be different?

There has been speculation that the Seos-15 when paired with a BMS-4550 might possibly be a little better, but most consider the Seos-12 and Seos-15 to be pretty close in terms of performance, especially with the DNA-360.

The woofers for the Cheap Thrill speaker were sold out at Parts Express. They won't be getting any more of those woofers in because they were a buy out.

I bought three before they were gone, so I will most likely end up making the 12" CT for my LCR.

Those prices do make you wonder what is possible if you were to buy in bulk. Crowd Source funded speaker project, anyone?

Props to Bill Waslo.

I have finished my Cheap Thrill build and these are everything I had hoped for. I set them up in my basement theater this afternoon and have enjoyed everything I have listened to thus far. Listening to Finnish classical guitarist Timo Korhonen I can hear the faint rustle of his clothes and his occasional breathing as he plays. (Most classical guitarist can't sit still as they play). I watched the 2009 Star Trek release and heard background noise on the bridge in several scenes I don't believe I noticed in previous viewings (I know, could be placebo).

I would not characterize the highs as harsh, and would characterize the mid-range as a little dark and very pleasing.

It's been fun. Up next are Fusion 8 for surrounds.

Finish was done with a tinted water based conversion varnish. I am lucky enough to have a friend who is a cabinet guy by trade.

What's a good value alternative right now ? Or then best next step up option ?

Was it determined you can just use the new model Celestion instead ?

Or should I look at alternate option?

if I'm correct the celestion alternative (TF1525) that Bill pointed out was the same driver that was used in the Karma 15 ... basically make the cheap thrills a Karma 15... I'm not sure if the Karma 15 was a step down from the CT (besides have 1mm less xmax on the woofer) or if it was a modified Karma 15 and the cheap buy out made it a better bang for your buck than the Karma 15. you'd have to ask Bill

I'm wondering how the Celestion TF1525-E would work in there. same Xmax as the buyout driver, and nearly the same price as the 1525 ... just don't know enough about the other specs to see if it's compatible.

I think I'd like to use DNA 360 anyways instead of 350


It's not much more - and it seems better right ?

I would love hear about this too. Anyone heard both? Or have an opinion ?

So which is better assuming your budget was unlimited? (Not asking about value, let's assume both cost $1- which is a better choice ?)
