Also, speaker level inputs are only for someone who does not have another preamp output to use. My solution for this problem is to get an electronic crossover. Speaker level inputs are a cost saving way out until you can afford the crossover.
Subwoofer insight.
This is new territory to me. Current speakers are 2 way with frequency response of 60Hz-20KHz with +/- 2dB. Sensitivity rated as 86dB. Chance to purchase a pair of REL 7 tis. I feel like I am missing something but will have to buy the subs to try out. My basic question is this. Does this purchase sound wise? I know what I am willing to spend but do you think I will notice an appreciable improvement. I know that no one can listen through my ears but this is my first time doing this. Source is 75 watt integrated tube amp, McIntosh MA-2275. Thoughts appreciated. I am leaning towards going forward with the deal but would appreciate some feedback. Room is large and open, 28X38 feet with 9 foot ceilings. Thanks for any feedback.

A simple 6db/oct XO HiPass is easy to make. See http://www.ielogical.com/assets/Audio/PassiveXO1.png for a picture The circuit is just a Y with the appropriate cap in the main amp line. Fc = 1/(2 π R C) where R is Ω and C is in F. 10nF is 0.000,000,010F R is amp input impedance See http://sim.okawa-denshi.jp/en/CRhikeisan.htm As a general rule for small 2 ways, ½ to an octave above the claimed -3db point is a good rule of thumb. e.g. for 60Hz speaker, 85 to 120Hz. 85Hz is not exactly ½ octave, but close enough. Use good caps. Teflon or Polypropylene or Polystyrene. Avoid mylar and worse. |
Simply visit their website and they have a page where you can enter the data of your room size and speakers and they will match you with the perfect subNonsense! Limited speaker brands, model choices and room parameters. An utter waste of time! Some of the most egregious sonic travesties experienced have included REL subs in dealer show rooms. 20 years ago REL were tops and they still make some very good subs today. Others are price point pathetics. |
I started my REL experience a while back with a used (200 bucks) Q150e 10" 150 watt little gem that works perfectly. I'm big on the "high level" Speakon connection as long runs of RCAs is just silly to me...balanced if available would be fine as is the wireless feature on new subs, but otherwise I simply made my REL cables from Canare Star Quad and it works swimmingly. My second used REL came along a couple of years later as a Q108MKII 100 watt 8". Also 200 bucks, also perfect. I'm in the "2 subs or more" crowd as it just makes bass seem more balanced and effortless...however, if one sub is all you can do, do it. Running the main speakers full range also sounds best to me, and since they're very efficient my main amp doesn't need any help with crossovers limiting its bass...I dial in the best sound from the main speakers and then roll in the subs to where they just sound right. Note my room sounds like a room, the room tuning consists of furniture, a rug, and a high sloping ceiling. No deleterious reflections or bass boom issues in my sweet spot. I turn the RELs up and down a little from time to time relative to the recording and very rarely use a Schiit Loki EQ...works for me. |
