    Re: Active 3 way, pro-sound drivers

    The Byz alignment is much like the AE alignment option you have there. The enclosure is small for this woofer, and the tune is very low. My anechoic F3 is upper 20s and a shallow roll off to F10 in the teens. But I sacrifice a lot of sensitivity, getting maybe 84dB for one watt.

    I rather like the specs for the AE you have there. For most music, 40Hz is plenty low, and with the shallow roll off those enclosures will offer to those massive 15" cones, I really feel like you'll get plenty of palpable bass. And while the long term power rating of the other woofer is higher, the AE has no trouble handling short term bursts to 1000W. The lower tuning option will probably be somewhat more problematic matching to the room and speaker position. And the AE has spectacular performance into the mid range. Getting it to integrate with the mids will be easy and give you a variety of options in terms of acoustic slope, with a 1st order slope a real option.
    Pete,

    Thanks for the info. What you say makes a lot of sense to me. I have this voice in the back of my mind telling me you are right and that I should not be chasing the lowest anechoic F3 and F10 I can get but rather look at what it will give me in room and how well that will work acoustically. It's hard to convince myself to give up the pretty graph that has that night flat line extending down deeper to the mid 20's. I will use this probably 80/20 for movies/music so deeper bass than music needs will be part of my desire. Obviously I'm not expecting infra bass into the teens out of this.

    Not much progress last night but as I continue on the build I'll add info.

    Thanks again for taking time to help educate a rookie,

      To say that it shocks first time listeners would not be an exaggeration. Think PA system style dynamics with mastering studio sound quality.

      Pete's right about their power handling too. Before I made the subs, we played around with EQ to see how low we could force them to play. Natural rolloff is around 70Hz in this cabinet, sealed. We pushed them flat to 40Hz and ran the Crown K2 wide open. Those cones were jumping! They didn't like it, but took the abuse just fine.

        What type of physician? I'm a psychiatrist.

        Just a note or warning. Over the years many people have ordered from AE (John Janowitz) and had to wait terribly long to hear from him or get any product. Many have given up in frustration and gone away mad after vilifying him online. It has not been about the product, but the lack of service.

          Steve,

          I'm an ENT. Glad to see I'm not the only doc crazy enough to be into diy sound gear. I have wondered that about AE. I've never tried to get speakers from them but the website is lacking and I've heard stuff about having to wait for batches to be built etc. The B&C woofers were back ordered a couple days but will ship tomorrow. Al at US Speakers is very good to deal with. If they get here and I open them then it's a done deal. I am still considering the options so perhaps I'll contact AE in the meantime to see if the td15s is in stock just so I'll know.

              You definitely have to patient with AE, otherwise look elsewhere. While mine is a bit extreme of a case due to a delay in parts from overseasd, the fact does remain that I initially placed my order for woofers in October, 2011, and I didn`t receive the final invoice until March, 2013

              I`m not saying I wouldn`t shop from AE again, but i wouldn`t do it knowing that it`s my only DIY project in the near future.

                I'm seeing good reports from AVS that group buy orders are already getting filled. This would be within a matter of weeks rather than years like the previous group buy. Here's to hoping John can keep the parts moving this time.

                Both times I've ordered(non group buy), I've had shipments within a week or two.

                  Well I just emailed to see if the TD15S is in stock. We'll see.

                    To the best of my knowledge, AE does not stock any drivers. Each one is built to order.

                      John sometimes stocks the TD-15M. I had a pair arrive in a couple of weeks.

                          Not that it helps, but there is a set of TD12Ss in the classifieds right now.

                            Well at $575 for the pair it is pretty much MSRP. I guess with a product that is good and also scarce you don't have to come down on price. The TD12S doesn't model too well in my box.

                            I think the B&C gives me a nice compromise between the deeper bass extension of a HiFi woofer like a RSS390 and a more traditional pro woofer like the AE products (at least with regards to the TS parameters; not trying to imply that their motors are traditional or lackluster). So with the B&C I get better extension than the TD woofers and better sensitivity than something like the RSS390. I'm sold

                            Updates to follow (slowly....)

                              Well, today I got the woofer cutouts done in the baffles. The boxes won't have any removable panels. I figure that with a hole that big in the baffle I'll be able to have adequate access to change anything needed just by removing the woofer.

                              My woofers haven't arrived yet (were out of stock at US Speakers). I did hear from John at AE that he has one pair of TD15S 4 ohm in stock that were built by mistake that are available for immediate shipping. Tempting...

                              I made one stupid measurement error and the hole on one baffle is 1/4" higher than the one on the other baffle. At the moment I'm not planning to rebuild that baffle. It certainly won't make any difference in the sound.

                                Looks like an excellent project!!

                                I run the TD15S in 170ltr tuned with 6" port 11" long. Enjoy it very much with all kinds of music.

                                The mids and tweeters are ones I've had my eye on for a long time.

                                I stuck with the Waynes new H290C horn and DE250 which may seem far from perfect wiht the 550hz dip and high Xover but the sound stage is excellent. A full 180deg or more with good recordings. I couldn't get that soundstage with a JBL 2118 and SB 29 crossed at 500 and 2K.

                                It'll be interesting to see how you make out with the parts you choose. You should have a dominating 2nd HD for a nice tone. That's hard to come by. And worth every penny. For those on a budget (under $2000) A three way with Td15S, 6ND430 and SB 29 crossed active at 550hz and passive at 2Khz could be a satisfying combo.
