Subwoofer Blending


I am considering buying a REL or Velodyne (or similar)subwoofer and want to "cut off" my Proac 2.5s at 50-60 HZ, blending in the subwoofer. I want to ease the burden on my SET and also get better bass response. I know most people recommend running speakers and subwoofer full range, I don't want to do this. Will I need an outboard electronic x-over or these products have built in x-overs for the purpose? Does my pre-amp need a special input for connection, would I just be able to use a line level input?

Hi, I have a general comment. More amps for the same money don't mean better sound than the same money spent on a "better" stereo or mono amp. You wont more push from you low watt amps I believe. If the single ended low watt sound is your thing and you wont more steam try what I did, also no cost for tube replacement etc. PASS ALEPH single ended amps probably have the sound you like and real horsepower to drive normal speakers but not very difficult speakers. I have mono 100watt ALEPH mod.2 and love them. Very Rare on used market but can be found ($3,000+used). The 30 watt stereo ALEPH is not the same weight and effortless sound and the 60watt stereo is good but not the = of the 100 watt mono. The 200 watt mono is going to cost a fortune in electric bills.

I believe a subwoofer is a mistake for most systems. I found that most speakers that go to 45hz with a decent 7 or 8in. woofer will produce plenty of base when the powersupply and sources are of high enought quality. Many products don't spend the $ on beefy powersupplies using first class parts. Your room size does effect base response in that a big room needed to have more air moved. 20 by 30ft. room will need need a 10in. driver of 87 to 90 db. with some real muscle before it to play a cello/stringbase conviencingly.

Last I believe you use a PLACETTE preamp. I am interested in them. Do you know anyone in the Chicago, Ill. area who owns one? Do you have the active model or the volume control alone? I am interested to hear more about this preamp. Thanks, in advance, for responding to my questions about the placette. Best wishes, good listening. Peter H.
