@craig john, @Mark Seaton

Craig and Mark, I just wanted to say thanks for your contributions over the last couple of days. The various aspects discussed are much clearer to me now due to your explanations. Thanks again.

Please drop in more often! smile.gif

Also, time didn't help the HF compression driver smooth out as much as I had hoped. ETA on the veneered Noesis: six weeks.
It will be nice to read your thoughts on a comparison between the two speakers. You came out strong in support of the JBls, But my guess is you will be more impressed with this purchase. A first hand comparison is the best way to decide. smile.gif
Congratulations
Chris

No, there isn't anywhere to read about the specs unless you can read Jeff's mind wink.gif. He is on his 3rd prototype woofer, the CD/Horn are ready and you saw the cabinet (nice little piece of work there). He did give me the basic specs on the custom designed woofer that I don't think he would mind my posting:

I just finished the design for the third 15" driver prototype which will be here in 2 weeks. The driver has 190oz magnet, 16.5mm xmax, 19hz fs.
That gives all the DIY'ers a heads up so that they can start speculating on material costs rolleyes.gif

But seriously wink.gif, this is going to be a very serious loudspeaker and clearly not for everyone. I was intrigued enough by the theory of this full range tower to sell of an already great performing system and pay the toll. How it will turn out is anyones guess, but it certainly is an interesting experiment in HT audio and I can't wait to get started playing. cool.gif

BTW, nice setup PI. smile.gif

No doubt. That is a fine looking speaker there. I would sure like to see the polars on that horn.

I can't wait for you to get them. Very anxious to hear your first impressions and how you set them up. It will be a beast...I'm so tempted to book a flight to your gtg!

They say they are rated for only 1625w, but what is my 15A outlet rated for??

I have one of these on each triax. I have run my system up to reference with the subs 6-8db hot and they didn't get hot or shut down.

I have some other remote on/off solutions listed on my web site. http://www.speakerpower.net/documents.html
I'll tear down one of these and perhaps add it to the list. Good to hear it is working for you.

At 16.5 mm xmax...... it looks like after 20hz they will have not.much left if any, if used as a primary sub systemd..... I could tell you within 30$ how much the driver are, Its not any mystery. all you have to do is look at any other offerings with close to the same specs and that will give you a good idea, then minus volume discount.
These look to be similar in specs to the dayton HO's but likely made by FI. woofers would be around 200$.

Still should be some serious speakers though!!!! Looking forward to getting mine.

They only have a 500 watt tungsten rating which suggests the relay contacts are not very robust. I'm not sure where a sub amp load falls on the resistive/tungsten scale, but until I know I'm leary. They're certainly inexpensive, but long term reliability is important to me.

Solid performance to 20 Hz will still give an impressive experience. Seems to me that going sans subs may be realistic as long as the room works with the placement.
post #15971 of 18474
Their - 3dB point was 18Hz so you can assume their port tune is somewhere in that realm.

I wouldn't expect much subsonic ULF performance out of a 20hz ported sub, any more than I expect it out of a ported tower.

I'm remain unconvinced subsonic ULF is worth pursuit - even after hearing sixteen 18" subwoofers in a small 1,500 cubic foot room and demoing many of the popular demo tracks specififically designed to highlight the merits of the ULF. In other words I wouldn't lose any sleep at all over the inability to reproduce subsonic ULF at high levels.
post #15972 of 18474
That Speakerpower SP2-4800 (2400wpc @ 4ohm x 2ch) would be a great 2 channel amp to drive to drive a pair of 215ts. That would be the same power as a Cap 2400, S1, or SubM HP.

I know the direct price went up but Jeff could probably hook someone up and Mark said he had plans of offering Speakerpower amps for sale. smile.gif

Wow! 215!!
post #15974 of 18474
Ok, the Noesis 212 and custom Noesis center are in the house smile.gif I also recenlty put in some bass traps, absorption panels and diffusion panels.

I've enjoyed my Monster Power HTS 5100 MK II for this purpose... You can get it for way below MSRP.

http://www.bhphotovideo.com/c/product/410411-REG/Monster_Power_109099_Signature_Series_HTS_5100.html

$254 shipped instead of $800.

Depending on rack vs. sub placement - it might be an option.

As to power filtering benefits - I can't say I hear a clear audible difference - but I can say it makes a clear visible difference in flickering on my projector (or lack of, when in use - through multiple projector tests) - and I do like the triggered/outlet based switching function -- you can have several different delay lengths set to different outlets.

Thanks Brandon. Jeff did a great job on the craftmanship of the center. Turned out better than I had thought it would.

Its the 228 body and 8 inch drivers with a 212 compression driver. Not sure the ID number of the BMS 212 compression driver but I assume it is what you posted smile.gif

What was the cost of it? I wonder if Jeff will start to offer this design now?

LOL.... I'm a little bummed he didn't come up with this last year when I bought my 228HT's...lol

Thanks for the kind comments Chris. I have a lot of character flaws including needing symmetry in my HT and being obsessive about cleanliness. I might have HT ADD smile.gif

Frohlich did you notice any improvement with the room treatments?

I can PM you the cost. Hint: start with a 228 add in the cost of the 212 compression driver, custom cabinet and crossover. I do think if he made it a regular production model with a cost between the 228 and 212, there would be a market for it.

As for as the room treatments, I want to say yes but when you add room treatments, and new pre/pro (went from XT to XT32) and new speakers in a short timeframe...it is hard to tell where the improvements came from. I would actually say going to XT32 and the Noesis were a bigger improvement then the bump I got from the room treatments.

Yeah sure if you don't mind PM me the price, if I had to take a guess of what a production version would cost if he put it into the lineup. I'd say $1800, basically minus the price of the 228HT's compression driver and add the cost of the 4593ND driver.

Welcome to the family.....biggrin.gif

I am thinking that you could eliminate the stands you have your Noesis sitting on......and pickup some 215's....wink.gif

Thanks, Chris! The JBL's were indeed impressive: midbass and midrange were the best I've ever heard in my system. Top octave was hit and miss on the JBL's. I know I won't get the same bass extension and impact with the 212HT, but working on a DIY build with quad 18" Epik Dragon drivers (in two dual opposed enclosures) to fill in below 80 Hz. I couldn't pass up $99 for these drivers in Epik's going-out-of-business sale, and with a pair of Behringer EP1500's laying around sounded like a fun project. I'm excited to hear the BMS 4593 driver I've read so much about - should be super clean and reasonably smooth throughout its entire range. I will post impressions when I get them dialed in.

Cheers,
Matt

I got tired of waiting for the 215...so I built my own. For you DIY guys, I used a 4593D compression driver, two 12" for mids, and one 18" for lows. Height is 90" and Baltic birch was used, but of course. cool.gif

Sorry, didn't get a chance to do a build thread. Next time wink.gif
